Invasive Ductal Carcinoma (causes)
Invasive ductal carcinoma (IDC),
also known
as infiltrating ductal carcinoma, is cancer that
began growing in a milk duct and has invaded the
fibrous or fatty tissue of the breast outside of
the duct. IDC is the most common form of breast
cancer, representing 80 percent of all breast
cancer diagnoses.
The causes of invasive ductal carcinoma have not been conclusively established. Researchers have determined that cancer can form when the cells in a milk-producing duct undergo changes that cause them to grow uncontrollably, divide very rapidly or remain viable longer than they should. The result is an accumulation of excess cells that can form a mass, or tumor, and potentially spread to nearby lymph nodes and distant areas of the body. The underlying reason for those cellular changes, however, remains unclear.
By evaluating the results of extensive studies, scientists have identified certain hormonal, environmental and lifestyle factors that are believed to influence a person's breast cancer risk, such as smoking, poor nutrition and prior radiation therapy administered to the chest area. Even so, it's important to keep in mind that some individuals who have no risk factors develop cancer, while others with one or more risk factors do not. Most likely, the precise cause is a complex interaction of many factors.
In rare cases, the causes of invasive ductal carcinoma have been traced to inherited attributes, such as mutations of the:
(a)
Breast cancer gene 1 (BRCA1), a tumor suppressor gene,
(b)
Breast cancer gene 2 (BRCA2), a tumor suppressor gene, or
(c)
ErbB2 gene, which produces the HER2 protein that promotes cellular proliferation.

Unraveling myoepithelial cell plasticity in breast cancer: a transcriptomic approach.
Journal of histotechnology, 49(3):162-172.
Myoepithelial cells (MECs) are integral to mammary gland physiology, classically serving a structural and tumor-suppressive role. While their function in normal breast tissue and ductal carcinoma in situ is well characterized, their behavior in human invasive breast cancer has not been previously examined. In this study, we performed a comprehensive transcriptomic analysis of MECs isolated from seven archived human breast cancer specimens, directly comparing them with MECs from adjacent normal tissue to define gene expression changes associated with invasive progression. The analysis revealed marked transcriptomic reprogramming across three key domains: extracellular matrix (ECM) interactions, epithelial-mesenchymal transition (EMT), and cellular signaling. Notable findings include stromal remodeling characterized by overexpression of 17 distinct collagen genes; compromise of the basement membrane through upregulation of matrix metalloproteinases (MMPs 2, 9, 11, and 14); and dysregulation of epithelial markers (KRT5, KRT7, KRT14), consistent with a phenotypic shift toward a cancer-associated fibroblast (CAF)-like state. In addition, increased expression of pro-tumorigenic mediators such as SPARC, POSTN, and integrin subunits was observed. Despite the limited sample size, these results indicate substantial molecular plasticity in MECs, suggesting a transition from a tumor-suppressive to a tumor-promoting phenotype during invasive disease. Overall, this study identifies a fundamental shift in myoepithelial identity and provides a critical framework for future investigations into the role of MEC plasticity in driving breast cancer progression.

Spatial Transcriptomics and Bulk RNA-Seq Analysis Revealed Molecular Classification of Invasive Lobular Carcinoma.
Cancer science, 117(9):2586-2601.
Invasive lobular carcinoma (ILC) is a special type of breast cancer. The histological subtypes of ILC exhibit diverse morphological features, and the prognosis differs accordingly. Compared with patients with classic-ILC (C-ILC), patients with pleomorphic-ILC (P-ILC) have a worse prognosis, owing to high-grade nuclear atypia and mitotic cells. However, the molecular differences between C-ILC and P-ILC remain unclear. To address this gap, we performed spatial transcriptomic profiling on four fresh-frozen C-ILC samples and four fresh-frozen P-ILC samples, followed by confirmation of reproducibility in bulk RNA-seq datasets. We identified significant enrichment of cellular response to heat stress in P-ILC. Furthermore, molecular clustering analysis using genes differentially expressed across ILC samples in spatial transcriptome revealed that ILC has three molecular subtypes: proliferative (PR), immunoreactive (IM), and stroma-rich (ST), associated with distinct prognostic outcomes. Although these molecular subtypes did not completely correspond to C-ILC or P-ILC, PR tended to include P-ILC, and ST tended to include C-ILC. These molecular clusters exhibited features comparable to previously reported subtypes. Despite these phenotypic features, ILC is generally treated similarly to invasive ductal carcinoma (IDC), with limited consideration of molecular subtype classification. Our findings suggest that molecular profiling may more accurately reflect prognosis than conventional histological classification and may provide potential diagnostic markers and therapeutic targets.

Tumor-Secreted ADAMTSL4 Activates Latent TGFβ1 to Drive Cancer Cachexia.
Cancer discovery pii:787577 [Epub ahead of print].
UNLABELLED: Cancer cachexia is a devastating wasting syndrome with no approved therapies. In this study, we identify the tumor-derived glycoprotein ADAMTSL4 as a circulating factor associated with body weight loss in preclinical cachexia models and patients with colorectal and lung cancers. In mice, Adamtsl4 overexpression converted non-cachexia-inducing tumors into cachexia-inducing tumors, whereas its deletion in cachexia-inducing tumors spared fat and muscle, blunted muscle atrophy signatures, and reduced cachexia severity. ADAMTSL4 engages the latency-associated peptide (LAP) of TGFβ1, promoting local activation of TGFβ1 at muscle cell membranes. Genetic blockade of proTGFβ1 or pharmacologic inhibition of TGFβ signaling reduced ADAMTSL4-dependent wasting in adipocytes and muscle cells. Suppression of tumor-derived ADAMTSL4 attenuated skeletal muscle fibrosis in mice. Together, the association between increased circulating ADAMTSL4 levels and TGFβ-driven muscle atrophy and fibrosis gene signatures in patients with cachectic cancer identifies ADAMTSL4 as an upstream regulator of TGFβ1 and a potential therapeutic target in cancer cachexia.
SIGNIFICANCE: Cancer cachexia lacks effective therapies and remains a major cause of cancer-related morbidity and mortality. We identify tumor-derived ADAMTSL4 as an upstream regulator of latent TGFβ activation via LAP engagement that promotes multiorgan wasting and fibrosis-related remodeling. Targeting ADAMTSL4 may provide a selective therapeutic strategy without systemic TGFβ pathway blockade.

Pilot randomized controlled trial of a peer coach-led behavioral and educational intervention to enhance quality of life in patients living with hypersensitivity pneumonitis: Protocol for the RISE-HP study.
Contemporary clinical trials communications, 53:101678.
BACKGROUND: Hypersensitivity Pneumonitis (HP) is an interstitial lung disease caused by an inhalational environmental exposure. Patients living with HP experience significant stress, uncertainty, and hypervigilance about the management of their disease and prognosis. These factors lead to reduced health-related quality of life (HRQOL), an important outcome that no interventions currently target.
OBJECTIVE: The goal of this behavioral and educational intervention, RISE-HP, is to improve HRQOL in people who have HP. The objective of this pilot study is to assess feasibility, acceptability, and preliminary effectiveness of the RISE-HP intervention.
METHODS: This pilot randomized controlled trial will be conducted in patients over the age of 18 with a diagnosis of HP. Forty participants will be randomly assigned to receive either the RISE-HP intervention (meetings with a peer coach focused on living well with their HP using cognitive behavioral techniques and motivational interviewing) or an attention control (general health education sessions with a research assistant) for 10 weeks. Participants will complete four additional study visits (enrollment, 5 weeks, 10 weeks, and 14 weeks after intervention start) for patient reported outcome measure completion. Primary implementation outcomes will be feasibility and acceptability. Secondary patient-centered effectiveness clinical outcomes will be improvement in HRQOL as measured by the Kings Brief Interstitial Lung Disease (KBILD) questionnaire. Additional secondary patient-reported clinical outcomes include fatigue, anxiety, depression, and self-efficacy.
CONCLUSION: Overall, this study addresses an important gap in HP care by targeting HRQOL and offers a novel non-pharmacologic patient-centered approach to therapy in patients with HP.

Association of EBV EBNA1 C-terminal variations with severity of Invasive ductal carcinoma.
Molecular biology reports, 53(1):.
BACKGROUND: Breast cancer is a major cause of mortality, and Epstein-Barr virus (EBV) is considered a potential contributor to cancer development. EBV nuclear antigen 1 (EBNA1) plays a vital role in viral persistence. This study aimed to investigate the association among EBNA1 C-terminal variations and severity of invasive ductal carcinoma (IDC).
METHOD: A total of 60 female participants, were included in this study. EBV positive biopsy samples (N = 30) were obtained from the breast cancer patients while 30 healthy females served as control. The C-terminal region of EBNA1 gene was amplified and sequenced. Statistical analysis was carried out using SPSS v25.
RESULT: Among the breast cancer patients, 97% had IDC and 3% had ductal carcinoma in situ. Regarding tumor grade, 3% of the patients had grade I, 63% had grade II and 33% had grade III tumors. The P-Thr (70%) and its co-infection with V-leu (30%) were observed predominantly in patients with higher grade; however, no significant association was observed. A total of 15 consensus single-nucleotide polymorphisms were observed along with six random mutations. No significant association was reported among random SNPs with breast cancer severity. Phylogenetic analysis shows that our sequences of P-Thr exhibited high similarity with reference sequence NC_009334. All control samples were EBV negative.
CONCLUSION: P-Thr was the predominant EBNA1 prototype in study population. However, no significant association was found between EBNA1 variations with breast cancer severity.

Effect of NIMA-related kinase 2B on the sensitivity of breast cancer to paclitaxel in vitro and vivo.
Tumour biology : the journal of the International Society for Oncodevelopmental Biology and Medicine, 39(5):1010428317699754.
NIMA-related kinase 2B has been known to be an important centrosome regulatory factor. The aim of this study was to investigate the effect of NIMA-related kinase 2B on the sensitivity of breast cancer to paclitaxel. We detected the expression of NIMA-related kinase 2B messenger RNA in MCF-10 cells, including MCF-10A, MCF-10AT, MCF-10DCIS.com , and MCF-10CA1a. The influence of NIMA-related kinase 2B in nude mouse was also detected. The association between NIMA-related kinase 2B and clinicopathological factors was explored in invasive ductal carcinoma tissues. NIMA-related kinase 2B was lowly expressed in the precancerous cells, MCF-10A and MCF-10AT, and it was highly expressed in carcinomatous cells, MCF-10DCIS.com and MCF-10CA1a. The upregulation of NIMA-related kinase 2B can introduce the growth of MCF-10AT cells, knockdown of NIMA-related kinase 2B could remarkably inhibit cell proliferation in MCF-10DCIS.com and MCF-10 CA1a cells. Comparing the volume of the xenografts in nude mouse, we found that the tumors treated by NIMA-related kinase 2B small interfering RNA associated with paclitaxel were the smallest among all the groups. Expression of NIMA-related kinase 2B messenger RNA was associated with higher histological grades, positive lymph node, and high Ki67 index (>20%). The partial response rates were 75.0% in NIMA-related kinase 2B negative (NIMA-related kinase 2B-) patients and 15.8% in NIMA-related kinase 2B++ patients. The progressive disease rates were 10.0% in NIMA-related kinase 2B- patients and 52.6% in NIMA-related kinase 2B++ patients (p = 0.002). Our findings suggested that NIMA-related kinase 2B could play a role in the development and progression of breast cancer. Combination treatment using NIMA-related kinase 2B small interfering RNA and paclitaxel might be a novel potential therapy method for breast cancer.

Correlations between Tumor to Background Ratio on Breast-Specific Gamma Imaging and Prognostic Factors in Breast Cancer.
Journal of Korean medical science, 32(6):1031-1037.
The purpose of this study was to investigate the correlations between tumor-to-background ratio (TBR) obtained from breast-specific gamma imaging (BSGI) and the prognostic factors of breast cancer. Sixty-seven patients with invasive ductal carcinoma who underwent preoperative BSGI were enrolled. The BSGI images were visually scored from 1 to 5 according to a breast imaging reporting and data system (BIRADS). The TBR results obtained from positive BSGI images were compared according to the following prognostic factors: tumor size; axillary lymph node metastasis; nuclear grade (NG); histologic grade (HG); subtype; Ki-67; and the expression profile of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2). Among 67 images, 60 were classified as a positive finding (sensitivity 89.6%). A higher TBR value was significantly correlated with tumor size ≥ 2 cm (P = 0.001), axillary lymph node metastasis (P = 0.007), high HG (P = 0.029), negative PR status (P = 0.036), and Ki-67 ≥ 14% (P = 0.007). The TBR showed a significant difference between the luminal A and non-luminal A subtypes (P = 0.007). On multivariate analysis, TBR had a high correlation with tumor size ≥ 2 cm, axillary lymph node metastasis, and negative PR status (P = 0.003, 0.048, and 0.030, respectively). A high TBR on BSGI was significantly correlated with poor prognostic factors of breast cancer. Luminal A subtype, a breast cancer subtype with more favorable prognosis, was associated with a low TBR on BSGI.

Breast Reconstruction With Postmastectomy Radiation: Choices and Tradeoffs.
Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 35(22):2467-2470.
The Oncology Grand Rounds series is designed to place original reports published in the Journal into clinical context. A case presentation is followed by a description of diagnostic and management challenges, a review of the relevant literature, and a summary of the authors' suggested management approaches. The goal of this series is to help readers better understand how to apply the results of key studies, including those published in Journal of Clinical Oncology, to patients seen in their own clinical practice. A 45-year-old premenopausal woman presented with multifocal cancer in the right breast, with lesions at 1:00 and 4:00, the largest measuring approximately 3 cm on exam, and multiple palpable right axillary lymph nodes. A core biopsy confirmed invasive ductal carcinoma, grade 2 of 3, that was estrogen receptor positive, progesterone receptor positive, and HER2 negative. Fine needle aspiration of a right axillary node confirmed metastatic carcinoma. A positron emission tomography (PET)/ computed tomography done before starting chemotherapy demonstrated an absence of metastatic disease with expected avidity in two separate breast masses and multiple conglomerated 1-2 cm level I and II axillary lymph nodes. She received neoadjuvant chemotherapy with doxorubicin plus cyclophosphamide, followed by paclitaxel, and had a complete clinical response with resolution of the breast and axillary masses on exam. A repeat PET/computed tomography demonstrated reduced size of the breast and axillary disease, and no significant residual PET avidity. Her breast surgeon recommended a right mastectomy with axillary node dissection. As part of her multidisciplinary treatment plan, she consulted with two plastic surgeons to discuss reconstruction options. Plastic Surgeon A advised placement of an implant at the time of mastectomy while Surgeon B contrasted the pros and cons of an autologous transverse rectus abdominis muscle flap reconstruction with an implant based reconstruction. Surgeon B believed that autologous reconstruction would yield the best long-term cosmetic outcome. Before making her surgery decision, the patient consulted with a radiation oncologist to discuss the effect radiation may have on her reconstruction outcome.

Development of mammary hyperplasia, dysplasia, and invasive ductal carcinoma in transgenic mice expressing the 8p11 amplicon oncogene NSD3.
Breast cancer research and treatment, 164(2):349-358.
PURPOSE: NSD3 has been implicated as a candidate driver oncogene from the 8p11-p12 locus, and we have previously published evidence for its amplification and overexpression in human breast cancer. This aim of this study was to further characterize the transforming function of NSD3 in vivo.
METHODS: We generated a transgenic mouse model in which NSD3 gene expression was driven by the MMTV promoter and expressed in mammary epithelium of FVB mice. Mammary glands were fixed and whole mounts were stained with carmine to visualize gland structure. Mammary tumors were formalin-fixed, and paraffin embedded (FFPE) tumors were stained with hematoxylin and eosin.
RESULTS: Pups born to transgenic females were significantly underdeveloped compared to pups born to WT females due to a lactation defect in transgenic female mice. Whole mount analysis of the mammary glands of transgenic female mice revealed a profound defect in functional differentiation of mammary gland alveoli that resulted in the lactation defect. We followed parous and virgin NSD3 transgenic and control mice to 50 weeks of age and observed that several NSD3 parous females developed mammary tumors. Whole mount analysis of the mammary glands of tumor-bearing mice revealed numerous areas of mammary hyperplasia and ductal dysplasia. Histological analysis showed that mammary tumors were high-grade ductal carcinomas, and lesions present in other mammary glands exhibited features of alveolar hyperplasia, ductal dysplasia, and carcinoma in situ.
CONCLUSIONS: Our results are consistent with our previous studies and demonstrate that NSD3 is a transforming breast cancer oncogene.

Pathomimetic avatars reveal divergent roles of microenvironment in invasive transition of ductal carcinoma in situ.
Breast cancer research : BCR, 19(1):56.
BACKGROUND: The breast tumor microenvironment regulates progression of ductal carcinoma in situ (DCIS) to invasive ductal carcinoma (IDC). However, it is unclear how interactions between breast epithelial and stromal cells can drive this progression and whether there are reliable microenvironmental biomarkers to predict transition of DCIS to IDC.
METHODS: We used xenograft mouse models and a 3D pathomimetic model termed mammary architecture and microenvironment engineering (MAME) to study the interplay between human breast myoepithelial cells (MEPs) and cancer-associated fibroblasts (CAFs) on DCIS progression.
RESULTS: Our results show that MEPs suppress tumor formation by DCIS cells in vivo even in the presence of CAFs. In the in vitro MAME model, MEPs reduce the size of 3D DCIS structures and their degradation of extracellular matrix. We further show that the tumor-suppressive effects of MEPs on DCIS are linked to inhibition of urokinase plasminogen activator (uPA)/urokinase plasminogen activator receptor (uPAR)-mediated proteolysis by plasminogen activator inhibitor 1 (PAI-1) and that they can lessen the tumor-promoting effects of CAFs by attenuating interleukin 6 (IL-6) signaling pathways.
CONCLUSIONS: Our studies using MAME are, to our knowledge, the first to demonstrate a divergent interplay between MEPs and CAFs within the DCIS tumor microenvironment. We show that the tumor-suppressive actions of MEPs are mediated by PAI-1, uPA and its receptor, uPAR, and are sustained even in the presence of the CAFs, which themselves enhance DCIS tumorigenesis via IL-6 signaling. Identifying tumor microenvironmental regulators of DCIS progression will be critical for defining a robust and predictive molecular signature for clinical use.

A Prostate Cancer "Nimbosus": Genomic Instability and SChLAP1 Dysregulation Underpin Aggression of Intraductal and Cribriform Subpathologies.
European urology, 72(5):665-674.
BACKGROUND: Intraductal carcinoma (IDC) and cribriform architecture (CA) represent unfavorable subpathologies in localized prostate cancer. We recently showed that IDC shares a clonal ancestry with the adjacent glandular adenocarcinoma.
OBJECTIVE: We investigated for the co-occurrence of "aggression" factors, genomic instability and hypoxia, and performed gene expression profiling of these tumors.
A total of 1325 men were treated for localized prostate cancer from four academic institutions (University Health Network, CHU de Québec-Université Laval, Memorial Sloan Kettering Cancer Center [MSKCC], and Erasmus Medical Center). Pathological specimens were centrally reviewed. Gene copy number and expression, and intraprostatic oxygenation were assessed.
IDC/CA was separately assessed for biochemical relapse risk in the Canadian and MSKCC cohorts. Both cohorts were pooled for analyses on metastasis.
RESULTS AND LIMITATION: Presence of IDC/CA independently predicted for increased risks of biochemical relapse (HRCanadian 2.17, p<0.001; HRMSKCC 2.32, p=0.0035) and metastasis (HRpooled 3.31, p<0.001). IDC/CA+ cancers were associated with an increased percentage of genome alteration (PGA [median] 7.2 vs 3.0, p<0.001), and hypoxia (64.0% vs 45.5%, p=0.17). Combinatorial genomic-pathological indices offered the strongest discrimination for metastasis (C-index 0.805 [clinical+IDC/CA+PGA] vs 0.786 [clinical+IDC/CA] vs 0.761 [clinical]). Profiling of mRNA abundance revealed that long noncoding RNA, SChLAP1, was the only gene expressed at >3-fold higher (p<0.0001) in IDC/CA+ than in IDC/CA- tumors, independently corroborated by increased SChLAP1 RNA in situ hybridization signal. Optimal treatment intensification for IDC/CA+ prostate cancer requires prospective testing.
CONCLUSIONS: The poor outcome associated with IDC and CA subpathologies is associated with a constellation of genomic instability, SChLAP1 expression, and hypoxia. We posit a novel concept in IDC/CA+ prostate cancer, "nimbosus" (gathering of stormy clouds, Latin), which manifests as increased metastatic capacity and lethality.
PATIENT SUMMARY: A constellation of unfavorable molecular characteristics co-occur with intraductal and cribriform subpathologies in prostate cancer. Modern imaging for surveillance and treatment intensification trials should be considered in this adverse subgroup.

Tumor-associated myoepithelial cells promote the invasive progression of ductal carcinoma in situ through activation of TGFβ signaling.
The Journal of biological chemistry, 292(27):11466-11484.
The normal myoepithelium has a tumor-suppressing nature and inhibits the progression of ductal carcinoma in situ (DCIS) into invasive ductal carcinoma (IDC). Conversely, a growing number of studies have shown that tumor-associated myoepithelial cells have a tumor-promoting effect. Moreover, the exact role of tumor-associated myoepithelial cells in the DCIS-to-IDC development remains undefined. To address this, we explored the role of tumor-associated myoepithelial cells in the DCIS-to-IDC progression. We developed a direct coculture system to study the cell-cell interactions between DCIS cells and tumor-associated myoepithelial cells. Coculture studies indicated that tumor-associated myoepithelial cells promoted the invasive progression of a DCIS cell model in vitro, and mechanistic studies revealed that the interaction with DCIS cells stimulated tumor-associated myoepithelial cells to secrete TGFβ1, which subsequently contributed to activating the TGFβ/Smads pathway in DCIS cells. We noted that activation of the TGFβ signaling pathway promoted the epithelial-mesenchymal transition, basal-like phenotypes, stemness, and invasiveness of DCIS cells. Importantly, xenograft studies further demonstrated that tumor-associated myoepithelial cells enhanced the DCIS-to-IDC progression in vivo Furthermore, we found that TGFβ-mediated induction of oncogenic miR-10b-5p expression and down-regulation of RB1CC1, a miR-10b-5p-targeted tumor-suppressor gene, contributed to the invasive progression of DCIS. Our findings provide the first experimental evidence to directly support the paradigm that altered DCIS-associated myoepithelial cells promote the invasive progression of DCIS into IDC via TGFβ signaling activation.

To address this, we explored the role of tumor-associated myoepithelial cells in the DCIS-to-IDC progression. We developed a direct coculture system to study the cell-cell interactions between DCIS cells and tumor-associated myoepithelial cells. Coculture studies indicated that tumor-associated myoepithelial cells promoted the invasive progression of a DCIS cell model in vitro, and mechanistic studies revealed that the interaction with DCIS cells stimulated tumor-associated myoepithelial cells to secrete TGFβ1, which subsequently contributed to activating the TGFβ/Smads pathway in DCIS cells. We noted that activation of the TGFβ signaling pathway promoted the epithelial-mesenchymal transition, basal-like phenotypes, stemness, and invasiveness of DCIS cells. Importantly, xenograft studies further demonstrated that tumor-associated myoepithelial cells enhanced the DCIS-to-IDC progression in vivo Furthermore, we found that TGFβ-mediated induction of oncogenic miR-10b-5p expression and down-regulation of RB1CC1, a miR-10b-5p-targeted tumor-suppressor gene, contributed to the invasive progression of DCIS. Our findings provide the first experimental evidence to directly support the paradigm that altered DCIS-associated myoepithelial cells promote the invasive progression of DCIS into IDC via TGFβ signaling activation.},

Nascent RNA sequencing reveals mechanisms of gene regulation in the human malaria parasite Plasmodium falciparum.
Nucleic acids research, 45(13):7825-7840.
Gene expression in Plasmodium falciparum is tightly regulated to ensure successful propagation of the parasite throughout its complex life cycle. The earliest transcriptomics studies in P. falciparum suggested a cascade of transcriptional activity over the course of the 48-hour intraerythrocytic developmental cycle (IDC); however, the just-in-time transcriptional model has recently been challenged by findings that show the importance of post-transcriptional regulation. To further explore the role of transcriptional regulation, we performed the first genome-wide nascent RNA profiling in P. falciparum. Our findings indicate that the majority of genes are transcribed simultaneously during the trophozoite stage of the IDC and that only a small subset of genes is subject to differential transcriptional timing. RNA polymerase II is engaged with promoter regions prior to this transcriptional burst, suggesting that Pol II pausing plays a dominant role in gene regulation. In addition, we found that the overall transcriptional program during gametocyte differentiation is surprisingly similar to the IDC, with the exception of relatively small subsets of genes. Results from this study suggest that further characterization of the molecular players that regulate stage-specific gene expression and Pol II pausing will contribute to our continuous search for novel antimalarial drug targets.

The Pathologic Finding of Combined Lobular Carcinoma In Situ and Invasive Lobular Cancer May Indicate more than Just a High-Risk Marker Role of Lobular Carcinoma In Situ.
The American surgeon, 83(5):482-485.
For years, lobular carcinoma In Situ (LCIS) has been considered a high-risk marker for developing breast cancer. It is well known that ductal carcinoma In Situ is a precursor for the development of invasive ductal carcinoma, and ductal carcinoma In Situ is reported to be present in invasive ductal carcinoma in at least 40 per cent of cases. A similar relationship between LCIS and invasive lobular carcinoma (ILC) remains in question. This study evaluates the incidence of synchronous LCIS and ILC at our institution. This is a retrospective review of our tumor registry database of women diagnosed with LCIS or ILC from 2000 to 2014. Pathology reports were evaluated to determine the incidence of pure ILC and mixed ILC/LCIS. Those with both LCIS/ILC (mixed group) and those with pure ILC (pure group) were compared for age, surgical intervention, lymph node involvement, tumor size, nuclear grade, and margins between these two groups. A total of 182 women were identified with LCIS, ILC, or mixed LCIS and ILC. There were 76 subjects with pure ILC and 90 with mixed LCIS and ILC. The median and age range for each group were 63.6 (range: 40-97) for the mixed and 64.1 (range: 40-86) for pure groups. Tumor size was evaluated for each group and the median tumor size was 2.5 cm (range: 0.1-7.0cm) for the mixed group and 3.0 cm (range: 0.5-12.5 cm) for the pure group. Nodal involvement was present in 35.23 per cent of the mixed group and 46.3 per cent in the pure group. Surgical treatment for each group was similar, with mastectomy being the preferred surgical option over breast conservation therapy in the mixed and pure groups, 67.07 and 64.71 per cent, respectively. Presently, LCIS is considered a marker, or risk factor, for development of future breast cancer. This retrospective study does identify a strong relationship, 54 per cent, between LCIS and ILC at diagnosis. This high percentage of concurrent LCIS and ILC in surgical/pathological specimens supports the notion that LCIS may in fact have a precursory role in development of invasive lobular carcinoma of the breast. Additional studies to further investigate this relationship between LCIS and ILC, including genomic analysis, are presently underway.

Improvement of hydration and epidermal barrier function in human skin by a novel compound isosorbide dicaprylate.
International journal of cosmetic science, 39(5):518-526.
OBJECTIVE: The study involved the synthesis of a novel derivative of caprylic acid - isosorbide dicaprylate (IDC) - and the evaluation of its potential in improving water homoeostasis and epidermal barrier function in human skin.
METHODS: The effect of IDC on gene expression was assayed in skin organotypic cultures by DNA microarrays. The results were then confirmed for a few key genes by quantitative PCR, immuno- and cytochemistry. Final validation of skin hydration properties was obtained by four separate clinical studies. Level of hydration was measured by corneometer either by using 2% IDC lotion alone vs placebo or in combination with 2% glycerol lotion vs 2% glycerol only. A direct comparison in skin hydration between 2% IDC and 2% glycerol lotions was also carried out. The epidermal barrier function improvement was assessed by determining changes in transepidermal water loss (TEWL) on the arms before and after treatment with 2% IDC lotion versus placebo.
RESULTS: IDC was found to upregulate the expression of AQP3, CD44 and proteins involved in keratinocyte differentiation as well as the formation and function of stratum corneum. A direct comparison between 2% IDC versus 2% glycerol lotions revealed a three-fold advantage of IDC in providing skin hydration. Severely dry skin treated with 2% IDC in combination with 2% glycerol showed 133% improvement, whereas 35% improvement was observed with moderately dry human skin.
CONCLUSION: Topical isosorbide dicaprylate favourably modulates genes involved in the maintenance of skin structure and function, resulting in superior clinical outcomes. By improving skin hydration and epidermal permeability barrier, it offers therapeutic applications in skin ageing.

Standard Pathologic Features Can Be Used to Identify a Subset of Estrogen Receptor-Positive, HER2 Negative Patients Likely to Benefit from Neoadjuvant Chemotherapy.
Annals of surgical oncology, 24(9):2556-2562.
BACKGROUND: The benefit of neoadjuvant chemotherapy (NAC) in patients with estrogen receptor-positive (ER+)/human epidermal growth factor receptor 2-negative (HER2-) breast cancers and in invasive lobular carcinoma (ILC) is uncertain due to the low rates of pathologic complete response (pCR).
OBJECTIVE: The aim of this study was to determine if pathologic features can identify subsets likely to benefit from NAC.
METHODS: Patients with stage I-III ER+, HER2- breast cancer receiving NAC were retrospectively reviewed. Endpoints were downstaging to breast-conserving surgery (BCS) and nodal pCR after NAC. Patients were grouped by progesterone receptor (PR) status and grade/differentiation (high grade or poor [HP] vs. non-HP).
RESULTS: From 2007 to 2016, 402 ER+/HER2- cancers in patients receiving NAC were identified. Median age was 50 years, 98% were clinical stage II-III, and 75% were cN+. Overall pCR rate was 5%; breast pCR in 7% and nodal pCR in 15% of cN+ patients (p < 0.0001). Patients with ILC initially ineligible for BCS (n = 56) were less likely to downstage than those with invasive ductal carcinoma (IDC; n = 183, 16 vs. 48%, p ≤ 0.0001), with a similar trend in the axilla (p = 0.086). The rates of BCS eligibility after NAC were highest in PR-/HP patients (62%) and lowest in PR+/non-HP patients (29%) [p = 0.005]. In the axilla, nodal pCR among cN+ patients (n = 301) ranged from 0 to 35% (p < 0.0001) within these groups, and was most frequent in PR-/HP patients.
CONCLUSIONS: ER+/HER2- patients most likely to benefit from NAC are those with PR- and HP tumors. Patients with ILC are unlikely to downstage in the breast or axilla compared with IDC. The use of these criteria can assist in defining the initial treatment approach.

Genetic, Phenotypic, and Interferon Biomarker Status in ADAR1-Related Neurological Disease.
Neuropediatrics, 48(3):166-184.
We investigated the genetic, phenotypic, and interferon status of 46 patients from 37 families with neurological disease due to mutations in ADAR1. The clinicoradiological phenotype encompassed a spectrum of Aicardi-Goutières syndrome, isolated bilateral striatal necrosis, spastic paraparesis with normal neuroimaging, a progressive spastic dystonic motor disorder, and adult-onset psychological difficulties with intracranial calcification. Homozygous missense mutations were recorded in five families. We observed a p.Pro193Ala variant in the heterozygous state in 22 of 23 families with compound heterozygous mutations. We also ascertained 11 cases from nine families with a p.Gly1007Arg dominant-negative mutation, which occurred de novo in four patients, and was inherited in three families in association with marked phenotypic variability. In 50 of 52 samples from 34 patients, we identified a marked upregulation of type I interferon-stimulated gene transcripts in peripheral blood, with a median interferon score of 16.99 (interquartile range [IQR]: 10.64-25.71) compared with controls (median: 0.93, IQR: 0.57-1.30). Thus, mutations in ADAR1 are associated with a variety of clinically distinct neurological phenotypes presenting from early infancy to adulthood, inherited either as an autosomal recessive or dominant trait. Testing for an interferon signature in blood represents a useful biomarker in this context.

Comparison of HER2 amplification status among breast cancer subgroups offers new insights in pathways of breast cancer progression.
Virchows Archiv : an international journal of pathology, 471(5):575-587.
Although the prognostic and predictive significance of human epidermal growth factor receptor 2 (HER2) in invasive breast cancer is well established, its role in ductal carcinoma in situ (DCIS) remains unclear. Reports on combined evaluation of both HER2 protein expression and HER2 amplification status in pure DCIS and DCIS adjacent to invasive ductal carcinoma (i.e., admixed DCIS) are scarce. In this study, immunohistochemistry and fluorescence in situ hybridization (FISH) were used to assess HER2 status in 72 cases of pure DCIS, 73 cases of DCIS admixed with invasive ductal carcinoma (IDC), and 60 cases of pure IDC. HER2 copy number-based amplification was present in 49% of pure DCIS, 16% of admixed DCIS, 18% of admixed IDC, and 8% of pure IDC. Amplified pure DCIS with clusters of HER2 signals showed a significantly lower HER2 copy number than amplified admixed DCIS with clusters. Whereas pure DCIS and admixed DCIS presented significant differences, the in situ and invasive component of admixed tumors showed striking similarities regarding mean HER2 and chromosome 17 centromere (CEP17) copy number, grade, and estrogen and progesterone receptor expression. The discrepant prevalence of HER2 amplification among breast cancer subgroups indirectly suggests that HER2 may not play a crucial role in the transition of in situ to invasive breast cancer. The similarities in HER2 amplification status between the in situ and invasive component of admixed tumors hint at a common biological pathway for both components. Our data support the theory that pure DCIS, pure IDC, and admixed lesions have a common progenitor, but can progress as separate lineages.

abstract = {Although the prognostic and predictive significance of human epidermal growth factor receptor 2 (HER2) in invasive breast cancer is well established, its role in ductal carcinoma in situ (DCIS) remains unclear. Reports on combined evaluation of both HER2 protein expression and HER2 amplification status in pure DCIS and DCIS adjacent to invasive ductal carcinoma (i.e., admixed DCIS) are scarce. In this study, immunohistochemistry and fluorescence in situ hybridization (FISH) were used to assess HER2 status in 72 cases of pure DCIS, 73 cases of DCIS admixed with invasive ductal carcinoma (IDC), and 60 cases of pure IDC. HER2 copy number-based amplification was present in 49% of pure DCIS, 16% of admixed DCIS, 18% of admixed IDC, and 8% of pure IDC. Amplified pure DCIS with clusters of HER2 signals showed a significantly lower HER2 copy number than amplified admixed DCIS with clusters. Whereas pure DCIS and admixed DCIS presented significant differences, the in situ and invasive component of admixed tumors showed striking similarities regarding mean HER2 and chromosome 17 centromere (CEP17) copy number, grade, and estrogen and progesterone receptor expression. The discrepant prevalence of HER2 amplification among breast cancer subgroups indirectly suggests that HER2 may not play a crucial role in the transition of in situ to invasive breast cancer. The similarities in HER2 amplification status between the in situ and invasive component of admixed tumors hint at a common biological pathway for both components. Our data support the theory that pure DCIS, pure IDC, and admixed lesions have a common progenitor, but can progress as separate lineages.},

Myiasis associated with an invasive ductal carcinoma of the left breast: case study.
Revista do Instituto de Medicina Tropical de Sao Paulo, 59:e35.
Most breast cancers originate in the ductal epithelium and are referred to as invasive ductal carcinoma. In this study we report on the clinical procedures adopted to diagnose myiasis in association with infiltrating metastatic breast carcinoma in a female patient. A 41 years old woman came to the Federal Hospital of Andaraà complaining of intense itching, warmth, redness and hardening of the breast, which had acquired the aspect of an orange peel. A lesion in the left breast was cavitated, dimpled, had fetid odor, and had fibrotic and infected air nodules filled with exudate and Dipteran larvae. The tissue was cleaned and 33 larvae were extracted. The patient was hospitalized and received Ivermectin. Eighteen of the larvae extracted from the patient were placed in 70% alcohol, and twelve were placed in a container with sterile wood shavings under controlled conditions until they metamorphosed into adults. The taxonomic identification of the flies revealed that the culprit was Cochliomyia hominivorax. A histopathological exam conducted three months earlier had revealed infiltrating ductal carcinoma. Two months after the myiasis treatment, the breast tissue had healed. The patient had waited ten days from the onset of the myiasis to seek treatment, and that delay interfered negatively in the prognosis of both the neoplasm and the myiasis. This study is relevant to public health in view of the strong social impact of myiasis.

Association of nuclear FOXP3 expression with low Ki67 index and better prognosis in patients with breast invasive ductal carcinoma.
Neoplasma, 64(5):754-761.
Recent studies have provided clear evidence that some types of human cancer cells expressed Forkhead Box Protein 3 (FOXP3). However, the presence and role of FOXP3 in breast cancer are still contradictory up to now. In this study, we detected the expression of FOXP3 protein by immunohistochemistry in 123 cases of breast invasive ductal carcinoma. It exhibited that the subcellular localization of FOXP3 expression in breast cancer cells is heterogeneous. In nucleus, FOXP3 expression ratio was 47.97% (59/123) and the nuclear FOXP3 expression was significantly associated with lower Ki67 index (P=0.041), negative vessel tumor embolus (P=0.024). It was also significantly correlated with the molecular subtypes of breast cancer (P=0.002), displaying the highest ratio in the Luminal A subtype (68.18%). Kaplan-Meier analysis indicated that high nuclear FOXP3 expression was associated with better overall survival (OS) (94.92% vs. 82.81%, P=0.022) and disease-free survival (DFS) (91.53% vs. 76.56%, P=0.026). Moreover, nuclear FOXP3 represented an independent prognostic factor for OS (P =0.033) in multivariate analysis. However, in cytoplasm, FOXP3 expression ratio was 63.41% (78/123) and no statistic prognostic significance was found. Thus, our data demonstrated that nuclear FOXP3 expression correlated with low Ki-67 index and better outcome in breast invasive ductal carcinoma, indicating that FOXP3 acted as a potential prognostic marker for breast cancer.

IQ-domain GTPase-activating protein 1 promotes the malignant phenotype of invasive ductal breast carcinoma via canonical Wnt pathway.
Tumour biology : the journal of the International Society for Oncodevelopmental Biology and Medicine, 39(6):1010428317705769.
IQ-domain GTPase-activating protein 1 is a scaffolding protein with multidomain which plays a role in modulating dishevelled (Dvl) nuclear translocation in canonical Wnt pathway. However, the biological function and mechanism of IQ-domain GTPase-activating protein 1 in invasive ductal carcinoma (IDC) remain unknown. In this study, we found that IQ-domain GTPase-activating protein 1 expression was elevated in invasive ductal carcinoma, which was positively correlated with tumor grade, lymphatic metastasis, and poor prognosis. Coexpression of IQ-domain GTPase-activating protein 1 and Dvl in the nucleus and cytoplasm of invasive ductal carcinoma was significantly correlated but not in the membrane. Postoperative survival in the patients with their coexpression in the nucleus and cytoplasm was obviously lower than that without coexpression. The positive expression rates of c-myc and cyclin D1 were significantly higher in the patients with nuclear coexpression of Dvl and IQ-domain GTPase-activating protein 1 than that with cytoplasmic coexpression, correlating with poor prognosis. IQ-domain GTPase-activating protein 1 significantly enhanced cell proliferation and invasion in invasive ductal carcinoma cell lines by interacting with Dvl in cytoplasm to promote Dvl nuclear translocation so as to upregulate the expression of c-myc and cyclin D1. Collectively, our data suggest that IQ-domain GTPase-activating protein 1 may promote the malignant phenotype of invasive ductal carcinoma via canonical Wnt signaling, and it could be used as a potential prognostic biomarker for breast cancer patients.

Prognostic impact of proliferation for resected early stage 'pure' invasive lobular breast cancer: Cut-off analysis of Ki67 according to histology and clinical validation.
Breast (Edinburgh, Scotland), 35:21-26.
INTRODUCTION: The intent of this analysis was to investigate and validate the prognostic potential of Ki67 in a multi-center series of patients affected by early stage 'pure' invasive lobular carcinoma (ILC).
METHODS: Clinical-pathological data of patients affected by ILC were correlated with overall survival and disease-free survival (OS/DFS); data from a parallel invasive ductal carcinoma (IDC) patients' cohort were gathered as well. The maximally selected Log-Rank statistics analysis was applied to Ki67 continuous variable to estimate the appropriate cut-off. The Subpopulation Treatment Effect Pattern Plot (STEPP) analysis was performed as well.
RESULTS: Data from overall 1097 (457/222 ILC: training/validation set; 418 IDC) patients were gathered. The identified optimal Ki67 cut-offs were 4% and 14% for DFS in ILC and IDC cohort, respectively. In ILC patients, the Ki67 cut-off was an independent OS predictor. Ten-years OS and DFS were 89.9% and 77.2% (p = 0.007) and 79.4% and 69.2% (p = 0.03) for patients with Ki67 ≤ 4% and >4%, respectively. In IDC patients, 10-years OS was 93.8% and 71.7%, p = 0.02, DFS was 84.0% and 52.6%, p = 0.0003, for patients with Ki67 ≤ 14% and >14%, respectively. In the validation set, the optimal Ki67 OS cut-off was 5%. The STEPP analysis showed that in the presence of low Ki67 values, IDC patients have a better DFS than ILC patients, while with the increase of values the prognosis tends to overlap.
CONCLUSIONS: Despite the retrospective design of the study, the prognostic relevance of Ki67 (as well as its optimal cut-off) seems to significantly differ according to breast cancer histology.

PSIP1/p75 promotes tumorigenicity in breast cancer cells by promoting the transcription of cell cycle genes.
Carcinogenesis, 38(10):966-975.
Breast cancer (BC) is a highly heterogeneous disease, both at the pathological and molecular level, and several chromatin-associated proteins play crucial roles in BC initiation and progression. Here, we demonstrate the role of PSIP1 (PC4 and SF2 interacting protein)/p75 (LEDGF) in BC progression. PSIP1/p75, previously identified as a chromatin-adaptor protein, is found to be upregulated in basal-like/triple negative breast cancer (TNBC) patient samples and cell lines. Immunohistochemistry in tissue arrays showed elevated levels of PSIP1 in metastatic invasive ductal carcinoma. Survival data analyses revealed that the levels of PSIP1 showed a negative association with TNBC patient survival. Depletion of PSIP1/p75 significantly reduced the tumorigenicity and metastatic properties of TNBC cell lines while its over-expression promoted tumorigenicity. Further, gene expression studies revealed that PSIP1 regulates the expression of genes controlling cell-cycle progression, cell migration and invasion. Finally, by interacting with RNA polymerase II, PSIP1/p75 facilitates the association of RNA pol II to the promoter of cell cycle genes and thereby regulates their transcription. Our findings demonstrate an important role of PSIP1/p75 in TNBC tumorigenicity by promoting the expression of genes that control the cell cycle and tumor metastasis.

Impact of the 21-gene recurrence score on outcome in patients with invasive lobular carcinoma of the breast.
Breast cancer research and treatment, 165(3):757-763.
PURPOSE: Invasive lobular carcinoma (ILC) of the breast has unique clinicopathologic characteristics, compared to invasive ductal carcinoma. The role of the 21-gene Recurrence Score (RS) has not been clearly defined for ILC. We sought to determine the prognostic value of RS and the impact of adjuvant chemotherapy on long-term survival in patients with ILC.
METHODS: Utilizing the Surveillance, Epidemiology and End Results database from 2004 to 2013, we identified records of women aged 18-74 years, diagnosed with estrogen receptor (ER)-positive ILC (stage I to III) with RS available. We categorized patients into risk groups based on the traditional RS cutoffs and into those of the Trial Assigning Individualized Options for Treatment (TAILORx). Five-year breast cancer-specific survival (BCSS) was analyzed using the Kaplan-Meier method and Cox proportional hazards models.
RESULTS: Of the 7316 women included, 21% were in the low-risk; 71%, intermediate-risk; and 8%, high-risk groups as per TAILORx RS cutoffs. The 5-year BCSS was 99% in the low-risk, 99% in the intermediate-risk, and 96% in the high-risk groups. A high-risk RS as per TAILORx cutoff was independently associated with increased mortality (hazard ratio [HR] of death 2.37, 95% confidence interval [CI] 1.14-4.95) when compared to a low-risk RS. In both the high-risk and intermediate-risk groups, adjuvant chemotherapy was not significantly associated with the HR of death (high-risk, HR 1.14, 95% CI 0.55-2.38; intermediate-risk, HR 1.08, 95% CI 0.62-1.87).
CONCLUSION: For patients with ER-positive ILC, 8% were in the high-risk and 72% were in the intermediate-risk groups as per the TAILORx RS cutoffs. In the high-risk group, the RS predicted a lower 5-year BCSS. Adjuvant chemotherapy did not seem to confer a survival benefit for either the intermediate- or the high-risk cohorts.

abstract = {PURPOSE: Invasive lobular carcinoma (ILC) of the breast has unique clinicopathologic characteristics, compared to invasive ductal carcinoma. The role of the 21-gene Recurrence Score (RS) has not been clearly defined for ILC. We sought to determine the prognostic value of RS and the impact of adjuvant chemotherapy on long-term survival in patients with ILC.
METHODS: Utilizing the Surveillance, Epidemiology and End Results database from 2004 to 2013, we identified records of women aged 18-74 years, diagnosed with estrogen receptor (ER)-positive ILC (stage I to III) with RS available. We categorized patients into risk groups based on the traditional RS cutoffs and into those of the Trial Assigning Individualized Options for Treatment (TAILORx). Five-year breast cancer-specific survival (BCSS) was analyzed using the Kaplan-Meier method and Cox proportional hazards models.
RESULTS: Of the 7316 women included, 21% were in the low-risk; 71%, intermediate-risk; and 8%, high-risk groups as per TAILORx RS cutoffs. The 5-year BCSS was 99% in the low-risk, 99% in the intermediate-risk, and 96% in the high-risk groups. A high-risk RS as per TAILORx cutoff was independently associated with increased mortality (hazard ratio [HR] of death 2.37, 95% confidence interval [CI] 1.14-4.95) when compared to a low-risk RS. In both the high-risk and intermediate-risk groups, adjuvant chemotherapy was not significantly associated with the HR of death (high-risk, HR 1.14, 95% CI 0.55-2.38; intermediate-risk, HR 1.08, 95% CI 0.62-1.87).
CONCLUSION: For patients with ER-positive ILC, 8% were in the high-risk and 72% were in the intermediate-risk groups as per the TAILORx RS cutoffs. In the high-risk group, the RS predicted a lower 5-year BCSS. Adjuvant chemotherapy did not seem to confer a survival benefit for either the intermediate- or the high-risk cohorts.},

Immune Escape in Breast Cancer During In Situ to Invasive Carcinoma Transition.
Cancer discovery, 7(10):1098-1115.
To investigate immune escape during breast tumor progression, we analyzed the composition of leukocytes in normal breast tissues, ductal carcinoma in situ (DCIS), and invasive ductal carcinomas (IDC). We found significant tissue and tumor subtype-specific differences in multiple cell types including T cells and neutrophils. Gene expression profiling of CD45[+]CD3[+] T cells demonstrated a decrease in CD8[+] signatures in IDCs. Immunofluorescence analysis showed fewer activated GZMB[+]CD8[+] T cells in IDC than in DCIS, including in matched DCIS and recurrent IDC. T-cell receptor clonotype diversity was significantly higher in DCIS than in IDCs. Immune checkpoint protein TIGIT-expressing T cells were more frequent in DCIS, whereas high PD-L1 expression and amplification of CD274 (encoding PD-L1) was only detected in triple-negative IDCs. Coamplification of a 17q12 chemokine cluster with ERBB2 subdivided HER2[+] breast tumors into immunologically and clinically distinct subtypes. Our results show coevolution of cancer cells and the immune microenvironment during tumor progression.Significance: The design of effective cancer immunotherapies requires the understanding of mechanisms underlying immune escape during tumor progression. Here we demonstrate a switch to a less active tumor immune environment during the in situ to invasive breast carcinoma transition, and identify immune regulators and genomic alterations that shape tumor evolution.

Invasive ductal carcinoma: relationship between pathological characteristics and the presence of axillary metastasis in 220 cases.
Revista do Colegio Brasileiro de Cirurgioes, 44(2):163-170.
OBJECTIVE: to analyze the relation of anatomopathological features and axillary involvement in cases of invasive ductal carcinoma.
METHODS: this is a cross-sectional study of 220 breast cancer patients submitted to radical mastectomy or quadrantectomy with axilar emptying, from the Mastology Service of the Assis Chateaubriand Maternity School, Ceará, Brazil. We submitted the tumors to histological processing and determined the histological (HG), tubular (TG) and nuclear (NG) grades, and the mitotic index (MI) by the classification of Scarff-Bloom-Richadson, verified the presence of angiolymphatic invasion (AI) and measured the largest tumor diameter (TD). We then correlated these variables with the presence of axillary metastases.
RESULTS: the mean patients'age was 56.81 years ± 13.28. Tumor size ranged from 0.13 to 22 cm, with an average of 2.23cm ± 2.79. HG3, TG3 and NG3 prevailed, respectively 107 (48.6%), 160 (72.7%) and 107 (48.6%). Mitotic indexes 1, 2 and 3 presented a homogeneous distribution, respectively 82 (37.2%), 68 (31%) and 70 (31.8%). We observed no relation between the HG, TG and NG with the occurrence of axillary metastases (p=0.07, p=0.22 and p=0.21, respectively). Mitotic indices 2 and 3 were related with the occurrence of axillary metastases (p=0.03). Tumors larger than 2cm and cases that presented angiolymphatic invasion had a higher index of axillary metastases (p=0.0003 and p<0.0001).
CONCLUSION: elevated mitotic indexes, tumors with a diameter greater than 2cm and the presence of angiolymphatic invasion were individuallyassociatedwith the occurrence of axillary metastases.

Maximizing the Clinical Benefit of Anthracyclines in Addition to Taxanes in the Adjuvant Treatment of Early Breast Cancer.
Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 35(23):2600-2603.
The Oncology Grand Rounds series is designed to place original reports published in the Journal into clinical context. A case presentation is followed by a description of diagnostic and management challenges, a review of the relevant literature, and a summary of the authors' suggested management approaches. The goal of this series is to help readers better understand how to apply the results of key studies, including those published in Journal of Clinical Oncology, to patients seen in their own clinical practice. A healthy 56-year-old postmenopausal woman discovered a palpable mass at the one o'clock position of the left breast. After an initial biopsy confirmed breast cancer, she underwent mastectomy and axillary node dissection for a left-sided breast cancer that measured 3.5 cm. There was extensive lymphovascular invasion. Pathology review indicated a poorly differentiated, grade 3 invasive ductal carcinoma and ductal carcinoma in situ (largest focus, 3.5 cm). The margins were negative. Two of the 11 axillary lymph nodes contained metastatic carcinoma. Immunohistochemical studies previously obtained on the core biopsy indicated that the tumor was positive for estrogen receptor expression (50%), negative for progesterone receptor expression, and had a Ki-67 score of 60%. There was no amplification of the human epidermal growth factor receptor 2/ neu gene. Staging scans were negative for metastatic disease. Our multidisciplinary tumor board recommended adjuvant chemotherapy, postmastectomy radiation therapy, and endocrine therapy. A 52-year-old postmenopausal woman presented with a palpable mass of the right breast. An initial core biopsy confirmed carcinoma in the breast. She underwent quadrantectomy and axillary node dissection. The final pathology report disclosed a moderately differentiated invasive ductal carcinoma (diameter, 2.5 cm). The margins were negative. None of the three sentinel lymph nodes contained metastatic carcinoma. Immunohistochemical studies showed that the tumor was positive for estrogen receptor expression (90%) and for progesterone receptor expression (40%) and had a Ki-67 score of 20%. There was no amplification of the human epidermal growth factor receptor 2/ neu gene. Staging scans were negative for metastatic disease. A genomic assay was obtained and suggested an intermediate to high risk of recurrence. Her past medical history was notable for hypertension and moderately overweight status (body mass index, 39 kg/m[2]). Our multidisciplinary tumor board recommended adjuvant chemotherapy, postsurgical radiation therapy, and endocrine therapy.

High expression of Rac1 is correlated with partial reversed cell polarity and poor prognosis in invasive ductal carcinoma of the breast.
Tumour biology : the journal of the International Society for Oncodevelopmental Biology and Medicine, 39(7):1010428317710908.
The change of cell polarity is usually associated with invasion and metastasis. Partial reverse cell polarity in IDC-NOS may play a role in lymphatic tumor spread. Rac1 is a kind of polarity related protein. It plays an important role in invasion and metastasis in tumors. We here investigated the expression of Rac1 and partial reverse cell polarity status in breast cancer and evaluated their value for prognosis in breast cancer. The association of the expression of Rac1 and MUC-1 with clinicopathological parameters and prognostic significance was evaluated in 162 cases of IDC-NOS paraffin-embedded tissues by immunohistochemical method. The Rac1 messenger RNA expression was measured by real-time polymerase chain reaction in 30 breast cancer patients, which was divided into two groups of partial reverse cell polarity and no partial reverse cell polarity. We found that lymph node metastasis of partial reverse cell polarity patients was higher than no partial reverse cell polarity patients (Z = -4.030, p = 0.000). Rac1 was upregulated in partial reverse cell polarity group than no partial reverse cell polarity group (Z = -3.164, p = 0.002), and there was correlationship between the expression of Rac1 and partial reverse cell polarity status (rs = 0.249, p = 0.001). The level of Rac1 messenger RNA expression in partial reverse cell polarity group was significantly higher compared to no partial reverse cell polarity group (t = -2.527, p = 0.017). Overexpression of Rac1 and partial reverse cell polarity correlates with poor prognosis of IDC-NOS patients (p = 0.011). Partial reverse cell polarity and lymph node metastasis remained as independent predictors for poor disease-free survival of IDC-NOS (p = 0.023, p = 0.046). Our study suggests that partial reverse cell polarity may lead to poor prognosis of breast cancer. Overexpression of Rac1 may lead to polarity change in IDC-NOS of the breast. Therefore, Rac1 could be a therapeutic target for breast cancer.

Breast Cancer in Patients of Rheumatoid Arthritis with Methotrexate Therapy Mimicking Histopathological Changes after Neoadjuvant Chemotherapy.
The Tokai journal of experimental and clinical medicine, 42(2):104-108.
Two breast cancer patients with a history of treatment for long-term rheumatoid arthritis (RA) had histological findings similar to histological changes seen in resected mammary gland specimens following neoadjuvant chemotherapy (NAC). The first patient was a 64-year-old woman who visited our hospital after feeling a lump in her left breast. The second patient was a 68-year-old woman who visited our hospital for an indentation in her left nipple. They were diagnosed with breast cancer following detailed examinations and underwent mastectomy. Both patients had a history of RA and were being treated with Methotrexate. The histological diagnoses of these patients were invasive ductal carcinoma, but frequent dispersal of cancer cell nests, stromal fibrosis, elastosis, edema and inflammatory cell infiltration were seen. Fibrosis was also found in the dissected lymph node. These histological findings were extremely similar to changes that occur in the mammary gland tissue after NAC; however, these patients had not undergone NAC. Methotrexate, which was being administered as an anti-rheumatic drug to the two patients, might have played a role similar to that of metronomic chemotherapy, which involves the continuous use of low-dose anti-cancer drugs, resulting in histological changes similar to those seen after NAC.

Pancreatic metastasis from invasive pleomorphic lobular carcinoma of the breast: a rare case report.
Diagnostic pathology, 12(1):52.
BACKGROUND: Invasive pleomorphic lobular carcinoma (PLC) is an aggressive subtype of invasive lobular carcinoma of the breast, which has its own histopathological and biological features. The metastatic patterns for PLC are distinct from those of invasive ductal carcinoma. In addition, pancreatic metastasis from PLC is extremely rare.
CASE PRESENTATION: We report a rare case of a 48-year-old woman presenting with clinical gastrointestinal symptoms and pancreatic metastasis of PLC. The pancreatic tumor was composed of pleomorphic tumor cells arranged in the form of solid sheets and nests and as single files, with frequent mitotic figures, nucleolar prominence, high nuclear to cytoplasmic ratio and loss of cohesion. The malignant cells were positive for p120 (cytoplasmic) and GATA3 and negative for estrogen receptor, progesterone receptor, human epidermal growth factor receptor 2, E-cadherin, gross cystic disease fluid protein 15 and mammaglobin, which indicated a lobular carcinoma phenotype of the breast.
CONCLUSIONS: To the best of our knowledge, this is one of the few reported cases in the literature of pancreatic metastasis of invasive lobular carcinoma of the breast, of which the definitive diagnosis was obtained only after surgery. Rare metastasis sites should be considered, particularly, when a patient has a medical history of PLC.

Atypical Proliferative (Borderline) Serous Tumor in the Brain: A Case Report.
International journal of gynecological pathology : official journal of the International Society of Gynecological Pathologists, 37(1):52-56.
A 59-year-old woman with a remote history of invasive ductal carcinoma of the breast was found on a follow-up computed tomography scan of her brain to have a 1-cm lesion in the right frontal lobe in 2008. In the ensuing years, before her current admission, multiple imaging studies of the brain revealed that the lesion was stable and it was, therefore, interpreted as a small area of encephalomalacia related to a thrombosed cortical vein, a cavernoma, or treated metastatic breast cancer. In 2013, the patient underwent a bilateral salpingo-oophorectomy for ovarian tumors that were diagnosed as bilateral serous cystadenofibromas. A partial omentectomy showed no evidence of implants. In June 2016, the brain lesion was completely excised and diagnosed as an atypical proliferative (borderline) serous tumor. Immunohistochemical staining demonstrated that the tumor cells were immunoreactive for Pax8, WT-1, ER, and CK-7 and negative for Gata-3, PR, TTF-1, CDX-2, Napsin A, and CK-20, which was consistent with that diagnosis. We present a brief review of possible mechanisms to account for this unusual presentation and speculate that the most likely one is exfoliation of fallopian tube epithelial cells into the peritoneal cavity, which then gain access to lymphatics resulting in cells implanting in the brain and subsequently progressing to an atypical proliferative (borderline) serous tumor.

Expression of podoplanin in stromal fibroblasts plays a pivotal role in the prognosis of patients with pancreatic cancer.
Surgery today, 48(1):110-118.
PURPOSE: To investigate the role of podoplanin (PDPN) expression in invasive ductal carcinoma of the pancreas (IDCP) in humans.
METHODS: Tumor samples were obtained from 95 patients with IDCP. Immunohistochemical staining was done to evaluate the expression of PDPN in cancer tissues.
RESULTS: PDPN was detected predominantly in stromal fibroblasts, stained with α-smooth muscle actin. The cutoff value of PDPN-positive areas was calculated according to a histogram. There was no significant difference in clinicopathologic factors between patients with high vs. those with low PDPN expression. The high PDPN group showed significantly poorer disease-free and disease-specific survival rates than the low PDPN group. Among patients from the high PDPN group, those with lymph node metastases and those with a tumor larger than 20 cm in diameter had significantly poorer prognoses than similar patients from the low PDPN group. Multivariate Cox proportional hazards analysis indicated that a high expression of PDPN was an independent risk factor for disease-specific survival.
CONCLUSIONS: PDPN expression in cancer-related fibrotic tissues is associated with a poor prognosis, especially in patients with large tumors or lymph node metastases.

Overexpression of Pofut1 and activated Notch1 may be associated with poor prognosis in breast cancer.
Biochemical and biophysical research communications, 491(1):104-111.
PURPOSE: The present study was to evaluate the prognostic value of protein expression of Pofut1 and Notch1 signaling in breast cancer.
MATERIAL AND METHODS: Formalin-fixed paraffin-embedded 314 breast specimens including 174 infiltrating ductal carcinoma(IDC), 50 ductal carcinoma in situ(DCIS) and 90 adjacent normal tissue(ANT) were immunohistochemically examined to evaluate the protein expression of Pofut1, activated Notch1(N1IC) and Slug on specimens. Survival analysis was performed by Kaplan-Meier method and Cox's proportional-hazards model. A online database was computationally used to further explore the prognostic role of Pofut1 and Notch1 mRNA expression by Kaplan-Meier Plotter.
RESULTS: Pofut1, Slug and N1IC expression were significantly increased in IDC compared to ANT(all p < 0.05). High expression of Pofut1, Slug and N1IC were associated with tumor aggressiveness including lymph node metastasis (LNM: p = 0.005 for Pofut1, p < 0.001 for N1IC, p = 0.017 for Slug), advanced stage(p = 0.039 for Pofut1, p = 0.025 for N1IC) and higher histological grade(p = 0.001 for N1IC). Additionally, high expression of Pofut1 was found to be significantly associated with high expressions of N1IC and Slug in IDC(r = 0.244, p = 0.001; r = 0.374, p < 0.001, respectively), similar correlation was also observed between high N1IC and Slug expression(r = 0.496, p < 0.001). Moreover, Kaplan-Meier and Cox's regression analysis indicated the significant prognostic value of elevated Pofut1, N1IC, Slug expressions, positive LNM and advanced tumor stage for the prediction of a shorter disease-free survival (DFS) and overall survival(OS). The web-based analysis also suggested a significant association of high Pofut1 and Notch1 mRNA expression with worse survival outcome.
CONCLUSION: Our findings suggested that overexpression of Pofut1 and activated Notch1 signaling may be associated with a poor prognosis in breast cancer.

Inpatient weight curve trajectory as a prognostic factor among adolescents with anorexia nervosa: a preliminary report.
Eating and weight disorders : EWD, 23(5):645-651.
OBJECTIVE: To investigate the predictive value of weight restoration trajectories for relapse within the first year after discharge from inpatient treatment among adolescents with AN.
METHODS: Forty four inpatient adolescents (5 boys, 39 girls) aged 11-18 (M 14.85, SD 1.87) diagnosed with anorexia were assessed at admission and discharge from a general hospital inpatient ward. Re-hospitalizations within 1 year of discharge were recorded. Factors assessed included 1/BMI at admission, 2/BMI at discharge, 3/percent from target weight (PFTW) at discharge, 4/length of hospitalization, and 5/a weight restoration trajectory measuring weight drops during inpatient weight restoration (rates of negative cubic variation in body weight (NCV).
RESULTS: Logistic regression indicated that negative cubic variation rates (NCV) predicted re-hospitalization. PFTW was found only marginally significant.
CONCLUSION: Variations in weight restoration during inpatient treatment may be used to identify patients at risk for relapse. NCV can alert clinicians to initiate early relapse prevention interventions before discharge. Level of Evidence Level III, cohort study.

Widespread alternative exon usage in clinically distinct subtypes of Invasive Ductal Carcinoma.
Scientific reports, 7(1):5568.
Cancer cells can have different patterns of exon usage of individual genes when compared to normal tissue, suggesting that alternative splicing may play a role in shaping the tumor phenotype. The discovery and identification of gene variants has increased dramatically with the introduction of RNA-sequencing technology, which enables whole transcriptome analysis of known, as well as novel isoforms. Here we report alternative splicing and transcriptional events among subtypes of invasive ductal carcinoma in The Cancer Genome Atlas (TCGA) Breast Invasive Carcinoma (BRCA) cohort. Alternative exon usage was widespread, and although common events were shared among three subtypes, ER+ HER2-, ER- HER2-, and HER2+, many events on the exon level were subtype specific. Additional RNA-seq analysis was carried out in an independent cohort of 43 ER+ HER2- and ER- HER2- primary breast tumors, confirming many of the exon events identified in the TCGA cohort. Alternative splicing and transcriptional events detected in five genes, MYO6, EPB41L1, TPD52, IQCG, and ACOX2 were validated by qRT-PCR in a third cohort of 40 ER+ HER2- and ER- HER2- patients, showing that these events were truly subtype specific.

Detection of Putative Stem-cell Markers in Invasive Ductal Carcinoma of the Breast by Immunohistochemistry: Does It Improve Prognostic/Predictive Assessments?.
Applied immunohistochemistry & molecular morphology : AIMM, 26(10):760-768.
INTRODUCTION: Experimental evidences from the last 2 decades supports the existence of a special type of neoplastic cell with stem-like features [cancer stem cell (CSC)] and their role in the pathophysiology and therapeutic resistance of breast cancer. However, their clinical value in human breast cancer has not been fully determined.
MATERIALS AND METHODS: An immunohistochemistry panel of 10 putative CSC markers (CD34, C-KIT, CD10, SOX-2, OCT 3/4, p63, CD24, CD44, CD133, and ESA/EPCAM) was applied to 74 cases of breast cancer, followed in a Regional Cancer Center of Minas Gerais State, Brazil, from 2004 to 2006. Possible associations between CSC markers and classic variables of clinicopathologic relevance were investigated.
RESULTS: The most frequently positive CSC markers were CD44, CD24, CD133, and ESA (the others were present in <15% of the cases). Two CSC profiles were defined: CD24/CD44 (CSC-1) and CD133/ESA (CSC-2). CSC-1 was significantly associated to patients older than 40 years, tumors of <2.0 cm in diameter, early clinical stages (P<0.05), and increased death risk of 4 times (P=0.03; 95% confidence interval, 1.09-14.41). CSC-2 was related to increased relapse risk of 3.75 times (P=0.04; 95% confidence interval, 1.02-13.69).
CONCLUSION: The detection of the most frequently positive CSC markers by immunohistochemistry is of clinicopathologic and prognostic relevance.

Breast cancer neoplastic seeding in the setting of image-guided needle biopsies of the breast.
Breast cancer research and treatment, 166(1):29-39.
PURPOSE: To identify clinicopathologic, technical, and imaging features associated with neoplastic seeding (NS) following image-guided needle breast biopsy.
METHODS: We performed an institutional review board-approved retrospective review of patients presenting with a new diagnosis of breast cancer or suspicious breast findings requiring biopsy with subsequent diagnosis of NS. The time from biopsy to NS diagnosis was calculated. Histology, grade, estrogen receptor (ER) status, progesterone receptor (PR) status, HER2 status, T category, and N category were recorded. Biopsy guidance method, needle gauge, and number of passes were reviewed in addition to the mammographic and sonographic features of the primary tumors and the NS.
RESULTS: Eight cases of NS were identified in 4010 patients. The mean time from biopsy to NS diagnosis was 60.8 days. The most frequent histology was invasive ductal carcinoma (7/8). Six cases were grade 3 (75.0%). Five primary breast cancers were ER, PR, and HER2 negative (62.5%). Seven patients underwent biopsy with ultrasound guidance. Multiple-insertion, non-coaxial ultrasound-guided core-needle biopsy was done in 6 cases. Mammographic presentation of NS was focal asymmetry (3/7 cases), mass (1/7), calcifications only (1/7), or occult (2/7). Sonographic presentation of NS was most often a mass (7/8) with irregular shape (5/7) and without circumscribed margins (6/7) and was occult in 1 case (1/8). NS distribution was subdermal and intradermal.
CONCLUSION: High-grade, triple-negative breast cancers and multiple-insertion, non-coaxial biopsies may be risk factors for NS. NS should be suspected on the basis of the superficial and linear pattern of disease progression in these patients.

GeneXpert HIV-1 quant assay, a new tool for scale up of viral load monitoring in the success of ART programme in India.
BMC infectious diseases, 17(1):506.
BACKGROUND: Recent WHO guidelines identify virologic monitoring for diagnosing and confirming ART failure. In view of this, validation and scale up of point of care viral load technologies is essential in resource limited settings.
METHODS: A systematic validation of the GeneXpert® HIV-1 Quant assay (a point-of-care technology) in view of scaling up HIV-1 viral load in India to monitor the success of national ART programme was carried out. Two hundred nineteen plasma specimens falling in nine viral load ranges (<40 to >5 L copies/ml) were tested by the Abbott m2000rt Real Time and GeneXpert HIV-1 Quant assays. Additionally, 20 seronegative; 16 stored specimens and 10 spiked controls were also tested. Statistical analysis was done using Stata/IC and sensitivity, specificity, PPV, NPV and %misclassification rates were calculated as per DHSs/AISs, WHO, NACO cut-offs for virological failure.
RESULTS: The GeneXpert assay compared well with the Abbott assay with a higher sensitivity (97%), specificity (97-100%) and concordance (91.32%). The correlation between two assays (r = 0.886) was statistically significant (p < 0.01), the linear regression showed a moderate fit (R[2] = 0.784) and differences were within limits of agreement. Reproducibility showed an average variation of 4.15 and 3.52% while Lower limit of detection (LLD) and Upper limit of detection (ULD) were 42 and 1,740,000 copies/ml respectively. The misclassification rates for three viral load cut offs were not statistically different (p = 0.736). All seronegative samples were negative and viral loads of the stored samples showed a good fit (R[2] = 0.896 to 0.982).
CONCLUSION: The viral load results of GeneXpert HIV-1 Quant assay compared well with Abbott HIV-1 m2000 Real Time PCR; suggesting its use as a Point of care assay for viral load estimation in resource limited settings. Its ease of performance and rapidity will aid in timely diagnosis of ART failures, integrated HIV-TB management and will facilitate the UNAIDS 90-90-90 target.

Amplification and overexpression of PSCA at 8q24 in invasive micropapillary carcinoma of breast.
Breast cancer research and treatment, 166(2):383-392.
PURPOSE: Invasive micropapillary carcinoma (IMPC) of the breast has distinct histological features and molecular genetic profiles. Gains/amplifications of 8q24 are found associated with IMPC. Although the prostate stem cell antigen (PSCA) gene is located at chromosome 8q24, and found over-expressed in prior studies, its prognostic values and biological significance in IMPC have not been well studied.
METHODS: Fluorescence in situ hybridization (FISH) was used to assess the frequencies of PSCA copy number gains in IMPC, invasive ductal carcinoma of no special type (IDC-NST), and invasive lobular carcinoma (ILC) samples. The protein expression levels of PSCA were examined in 56 IMPC, 72 IDC-NST, and 56 ILC samples using immunohistochemical analysis.
RESULTS: PSCA gene amplification was detected in 45.2% (14/31) of the IMPC, 28.1% (9/32) of the IDC-NST, and none (0/25) of the ILC. PSCA protein expression was observed in 58.9% (33/56), 40.3% (29/72), and 3.6% (2/56) of IMPC, IDC-NST, and ILC samples, respectively. The concordant rate of the immunohistochemistry and FISH data was 85.2%. PSCA gene amplification highly correlated with its protein overexpression (rs = 0.687, P < 0.001), suggesting that gene amplification is an important mechanism involved in PSCA overexpression. Our univariate analysis showed that the patients with PSCA-positive IMPC had a decreased disease-free survival (DFS) compared to PSCA-negative IMPC patients (P = 0.003). Our multivariate analysis confirmed the worse DFS in PSCA-positive IMPC patients (P = 0.022).
CONCLUSIONS: Our results indicate that PSCA may be an attractive target in the 8q24 amplicon and that it may serve as a molecular marker of metastasis and recurrence in IMPC. The differential expression of PSCA may be associated with cell adhesion. Detection of PSCA protein and gene amplification may help manage and predict the prognosis of IMPC patients.

HPK1 positive expression associated with longer overall survival in patients with estrogen receptor-positive invasive ductal carcinoma‑not otherwise specified.
Molecular medicine reports, 16(4):4634-4642.
Hematopoietic progenitor kinase 1 (HPK1) belongs to the mitogen activated protein kinase kinase kinase kinase (MAP4K) family of serine/threonine kinases, which have been associated with the incidence and progression of a variety of gastrointestinal malignant tumors in humans. However, the potential association between HPK1 expression and breast cancer, particularly invasive ductal carcinoma‑not otherwise specified (IDC‑NOS) development, has not yet been examined. To address this gap, the present study aimed to evaluate HPK1 expression in IDC‑NOS samples and to determine a relationship with clinical prognostic indicators, such as the expression levels of estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2), as well as overall survival of the patients with IDC‑NOS. HPK1 mRNA and protein expression in samples from 148 patients with IDC‑NOS were detected using immunohistochemistry, western blotting and reverse transcription‑quantitative polymerase chain reaction. A total of 54 out of 148 (36.5%) samples were HPK1‑positive, and 100 out of 148 (67.6%) were ER‑positive. Of the latter, 28% (28/100) were HPK1‑positive, and a significant negative association of HPK1 expression with ER positivity was observed (P=0.002; r=‑0.254). In addition, 43.2% (64/148) and 32.4% (48/100) of IDC‑NOS tissues were PR‑ or HER2‑positive, respectively; however, neither indicator correlated with HPK1 (P=0.109 and P=0.558, respectively). HPK1 expression, axillary lymph node metastasis and tumor‑node‑metastasis (TNM) stage were identified as independent factors of overall survival (OS) in the ER‑positive group (P<0.05), and HPK1 positivity was associated with increased OS (P=0.048). HPK1 mRNA levels did not differ between IDC‑NOS and normal adjacent breast tissues, whereas HPK1 protein levels were lower in IDC‑NOS (P<0.05). These results suggested that HPK1 protein may be a potentially effective IDC-NOS therapeutic target.

Bcl-2 antigen expression in luminal A and triple-negative breast cancer.
Medical oncology (Northwood, London, England), 34(9):161.
Biomarkers for the prognosis of breast cancer have been routinely used in clinical practice, including the expression of hormone receptors, Ki-67 and HER-2. More recently, Bcl-2 has been recognized as an important prognostic factor in breast cancer, although controversies persist with respect to the significance of its expression. The aim of the present study was to evaluate Bcl-2 antigen expression in luminal A and triple-negative breast cancer. Sixty women with invasive ductal carcinoma were included in the study and divided into two groups: Group A (luminal A) and Group B (triple-negative), with 30 cases in each group. Immunohistochemistry was performed on tissue sections to evaluate Bcl-2 antigen expression. Fisher's exact test was used to compare the proportions of cases with cells expressing Bcl-2 between the two subtype cancer groups, with statistical significance being established at p < 0.05. The number of cases with cells expressing Bcl-2 in Groups A and B was 26 (86.7%) and 12 (40.0%), respectively (p < 0.0003). In the present study, the expression of the anti-apoptotic protein Bcl-2 was greater in luminal A breast cancer tissue samples compared to triple-negative breast cancer.

Hormesis enables cells to handle accumulating toxic metabolites during increased energy flux.
Redox biology, 13:674-686.
Energy production is inevitably linked to the generation of toxic metabolites, such as reactive oxygen and carbonyl species, known as major contributors to ageing and degenerative diseases. It remains unclear how cells can adapt to elevated energy flux accompanied by accumulating harmful by-products without taking any damage. Therefore, effects of a sudden rise in glucose concentrations were studied in yeast cells. This revealed a feedback mechanism initiated by the reactive dicarbonyl methylglyoxal, which is formed non-enzymatically during glycolysis. Low levels of methylglyoxal activate a multi-layered defence response against toxic metabolites composed of prevention, detoxification and damage remission. The latter is mediated by the protein quality control system and requires inducible Hsp70 and Btn2, the aggregase that sequesters misfolded proteins. This glycohormetic mechanism enables cells to pre-adapt to rising energy flux and directly links metabolic to proteotoxic stress. Further data suggest the existence of a similar response in endothelial cells.

abstract = {Energy production is inevitably linked to the generation of toxic metabolites, such as reactive oxygen and carbonyl species, known as major contributors to ageing and degenerative diseases. It remains unclear how cells can adapt to elevated energy flux accompanied by accumulating harmful by-products without taking any damage. Therefore, effects of a sudden rise in glucose concentrations were studied in yeast cells. This revealed a feedback mechanism initiated by the reactive dicarbonyl methylglyoxal, which is formed non-enzymatically during glycolysis. Low levels of methylglyoxal activate a multi-layered defence response against toxic metabolites composed of prevention, detoxification and damage remission. The latter is mediated by the protein quality control system and requires inducible Hsp70 and Btn2, the aggregase that sequesters misfolded proteins. This glycohormetic mechanism enables cells to pre-adapt to rising energy flux and directly links metabolic to proteotoxic stress. Further data suggest the existence of a similar response in endothelial cells.},

Histone 4 lysine 8 acetylation regulates proliferation and host-pathogen interaction in Plasmodium falciparum.
Epigenetics & chromatin, 10(1):40.
BACKGROUND: The dynamics of histone modifications in Plasmodium falciparum indicates the existence of unique mechanisms that link epigenetic factors with transcription. Here, we studied the impact of acetylated histone code on transcriptional regulation during the intraerythrocytic developmental cycle (IDC) of P. falciparum.
RESULTS: Using a dominant-negative transgenic approach, we showed that acetylations of histone H4 play a direct role in transcription. Specifically, these histone modifications mediate an inverse transcriptional relationship between the factors of cell proliferation and host-parasite interaction. Out of the four H4 acetylations, H4K8ac is likely the rate-limiting, regulatory step, which modulates the overall dynamics of H4 posttranslational modifications. H4K8ac exhibits maximum responsiveness to HDAC inhibitors and has a highly dynamic distribution pattern along the genome of P. falciparum during the IDC. Moreover, H4K8ac functions mainly in the euchromatin where its occupancy shifts from intergenic regions located upstream of 5' end of open reading frame into the protein coding regions. This shift is directly or indirectly associated with transcriptional activities at the corresponding genes. H4K8ac is also active in the heterochromatin where it stimulates expression of the main antigenic gene family (var) by its presence in the promoter region.
CONCLUSIONS: Overall, we demonstrate that H4K8ac is a potential major regulator of chromatin-linked transcriptional changes during P. falciparum life cycle which is associated not only with euchromatin but also with heterochromatin environment. This is potentially a highly significant finding that suggests a regulatory connection between growth and parasite-host interaction both of which play a major role in malaria parasite virulence.

PD-L1 in breast cancer: comparative analysis of 3 different antibodies.
Human pathology, 72:28-34.
The interaction of programmed cell death-1 and its ligand-1 (PD-L1) serves as a regulatory check against excessive immune response to antigen and autoimmunity. We compared the performance of 3 different PD-L1 antibodies (Ventana SP263, Dako 22C3, and BioCare RbMCAL10 antibodies) in 136 invasive ductal carcinoma specimens including 43 primary, 48 locally metastatic, and 46 distantly metastatic diseases. PD-L1 expression was correlated with clinicopathologic parameters including tumor size, grade, lymphovascular invasion, estrogen receptor, progesterone receptor, HER2, Ki67, molecular type, and triple-negative status. There was excellent agreement between the 3 antibodies, with highly significant κ values (P≤.001). PD-L1 expression was more likely to be associated with higher tumor grade and estrogen receptor-negative, progesterone receptor-negative, triple-negative, and highly proliferative tumors (P<.001). When we studied PD-L1 expression at 0, 1%-9%, 10%-49%, and ≥50% cutoff points by the 3 antibodies, there were 20 discordant cases between the antibodies. Sixteen were of inconsequential impact as far as low and high PD-L1 expression. The 4 differences between antibodies did exhibit an interesting pattern of expression, where there was a general agreement between the BioCare and Ventana antibodies with consistently higher PD-L1 expression compared with the Dako antibody. Given the high concordance, it is not surprising that all 3 antibodies demonstrated the same associations with all pathologic and clinical parameters studied. Standardization studies to identify reliable biomarkers that help in patient selection for immune therapy to improve the risk-benefit ratio for these drugs are still needed.

Onychomadesis associated with chemotherapy: case report and mini literature review.
Drug design, development and therapy, 11:2373-2376.
The side effects of chemotherapy drugs have increased in recent years, and some side effects can lead to onychomadesis. A 72-year-old woman who was diagnosed with an invasive ductal carcinoma of the right breast underwent a modified radical mastectomy in April 2015, followed by chemotherapy with capecitabine and nanoparticle albumin-bound paclitaxel (nab-paclitaxel). Subsequently, the patient experienced palmoplantar redness, pain, onycholysis, a transparent serous exudate, and onychomadesis. The chemotherapy was discontinued, and the patient was treated with oral vitamin B6, a polymyxin ointment, and a high-energy red light. The palmoplantar redness and pain were alleviated after 1 month. However, although her fingernails improved, dysesthesia symptoms remained, and all her toenails exhibited defects or deformities at a 24-month follow-up. The symptoms of this disorder should be recognized by dermatologists.

Solitary Adrenal Metastases from Breast Invasive Ductal Carcinoma.
Chirurgia (Bucharest, Romania : 1990), 112(4):473-476.
The usual neoplastic dissease involving suprarenal glands are adrenal metastaes. The majority of suprarenal metastatic disease arise from lung cancer, followed by the stomach and colon cancer, oesophagus, the liver/bile ducts cancer and renal cell carcinoma. Invasive mammary carcinoma usually spreads to the bones, lungs, lymph nodes, liver and the brain. Adrenal gland metastases from invasive no special type carcinoma represents an extremly low rate number of cases. We discuss about a 66 year old patient who presented with a solitary adrenal metastases from triple negative breast invasive carcinoma. The patient underwent total left adrenalectomy in June 2016. No further adjuvants therapies were performed. At the time of writing the patient is in good condition, without any evidence of recurrence. The role of surgical and adjuvant therapy in treating adrenal metastases after breast cancer in survival rate will be determined in future studies.

FGFR2-Driven Signaling Counteracts Tamoxifen Effect on ERα-Positive Breast Cancer Cells.
Neoplasia (New York, N.Y.), 19(10):791-804.
Signaling mediated by growth factors receptors has long been suggested as one of the key factors responsible for failure of endocrine treatment in breast cancer (BCa). Herein we present that in the presence of tamoxifen, FGFs (Fibroblast Growth Factors) promote BCa cell growth with the strongest effect being produced by FGF7. FGFR2 was identified as a mediator of FGF7 action and the FGFR2-induced signaling was found to underlie cancer-associated fibroblasts-dependent resistance to tamoxifen. FGF7/FGFR2-triggered pathway was shown to induce ER phosphorylation, ubiquitination and subsequent ER proteasomal degradation which counteracted tamoxifen-promoted ER stabilization. We also identified activation of PI3K/AKT signaling targeting ER-Ser167 and regulation of Bcl-2 expression as a mediator of FGFR2-promoted resistance to tamoxifen. Analysis of tissue samples from patients with invasive ductal carcinoma revealed an inversed correlation between expression of FGFR2 and ER, thus supporting our in vitro data. These results unveil the complexity of ER regulation by FGFR2-mediated signaling likely to be associated with BCa resistance to endocrine therapy.

Expression of YES-associated protein (YAP) and its clinical significance in breast cancer tissues.
Human pathology, 68:166-174.
The transcriptional co-activator YES-associated protein (YAP) has been reported to act as both an oncogene and tumor suppressor in breast cancers. In this study, we evaluated YAP expression immunohistochemically in 324 breast cancer tissues and correlated the expression with clinicopathological findings and patient survival data. Additionally, we reviewed the literature to clarify the role of YAP in breast cancer. We detected YAP, estrogen receptor, progesterone receptor (PR), and human epidermal growth receptor-2 (HER2) expression and a Ki67 labeling index >20% in 53.4%, 49.0%, 45.0%, 28.3%, and 57.4% of invasive ductal carcinoma tissues, respectively. YAP is mainly localized within the tumor cell nuclei, and its expression was associated with the PR status and luminal A subtype. YAP expression also inversely correlated with the HER2 and Ki67 levels and lymph node metastasis. Kaplan-Meier curves revealed associations of YAP expression with favorable disease-free survival (DFS) and overall survival in patients with luminal A breast cancer and with favorable DFS association among patients with invasive ductal carcinoma, luminal B (HER2-), and luminal B (HER2+) breast cancers. A multivariate Cox analysis revealed that YAP expression and PR status were independent favorable predictors of DFS and overall survival, respectively, among patients with breast cancer, whereas tumor-node-metastasis stage and an old age were independent predictors of a poor DFS. Our results, together with the literature review findings, suggest that YAP could be a prognostic marker in patients with breast cancer.

Expression of periostin in breast cancer cells.
International journal of oncology, 51(4):1300-1310.
Periostin (POSTN) is a protein involved in multiple processes important for cancer development, both at the stage of cancer initiation and progression, as well as metastasis. The aim of this study was to determine the expression of POSTN in the cells of non-invasive ductal breast carcinoma in situ (DCIS) and invasive ductal carcinoma (IDC) and to correlate it with clinicopathological data. Immunohistochemical studies (IHC) were conducted on 21 cases of fibrocystic breast change (FC), 44 cases of DCIS and 92 cases of IDC. POSTN expression at mRNA (real-time PCR) and protein level (western blot analysis) was also confirmed in selected breast cancer cell lines (MCF-7, SK-BR-3, MDA-MB-231 and BO2). Statistically significant higher level of POSTN expression in IDC and DCIS cancer cells compared to FC was noted. Also, the level of POSTN expression in the cytoplasm of IDC cells was shown to increase with the increasing degree of tumour malignancy (G) and significantly higher expression of POSTN was observed in each degree of tumour malignancy (G) relative to FC. Statistically significant higher POSTN expression was observed in tumours with estrogen receptor-negative (ER-) and progesterone receptor-negative (PR-) phenotypes in comparison to estrogen receptor-positive (ER+) and progesterone receptor-positive (PR+) cases, as well as significant negative correlation between POSTN expression in cancer cells and expression of ER and PR (p<0.05). Additionally, statistically significant differences in POSTN expression were shown between particular breast cancer cell lines, both at mRNA and protein level. Observed POSTN expression was the lowest in the case of MCF-7, and the highest in MDA-MB-231 and BO2 of the most aggressive potential clinically corresponding to G3 tumours. POSTN expression in the cytoplasm of IDC cancer cells may play an important role in cancer transformation mechanism.

Also, the level of POSTN expression in the cytoplasm of IDC cells was shown to increase with the increasing degree of tumour malignancy (G) and significantly higher expression of POSTN was observed in each degree of tumour malignancy (G) relative to FC. Statistically significant higher POSTN expression was observed in tumours with estrogen receptor-negative (ER-) and progesterone receptor-negative (PR-) phenotypes in comparison to estrogen receptor-positive (ER+) and progesterone receptor-positive (PR+) cases, as well as significant negative correlation between POSTN expression in cancer cells and expression of ER and PR (p<0.05). Additionally, statistically significant differences in POSTN expression were shown between particular breast cancer cell lines, both at mRNA and protein level. Observed POSTN expression was the lowest in the case of MCF-7, and the highest in MDA-MB-231 and BO2 of the most aggressive potential clinically corresponding to G3 tumours. POSTN expression in the cytoplasm of IDC cancer cells may play an important role in cancer transformation mechanism.},

A single nucleotide polymorphism in codon F31I and V57I of the AURKA gene in invasive ductal breast carcinoma in Middle East.
Medicine, 96(37):e7933.
Although few studies have suggested a carcinogenic role for polymorphism of F31I and V57I codons of AURKA gene in invasive ductal carcinoma, contradictory results from different populations mandates regional investigations. We aimed to determine polymorphisms of F31I and V57I codons of AURKA gene and their association with cancer prognosis in patients compared with controls in an eastern population of Iran.A case-control study was conducted on specimens from 100 patients and 100 age- and gender-matched controls. DNA was extracted and the codons F31I and V57I were amplified. The different genotypes were analyzed by PCR-RFLP and electrophoresis.In codon F31I, the frequency of Phe/Ile was 70% and 82% in patients and healthy controls respectively, whereas (Ile/Ile) was 30% in patients and 18% in healthy (P = .047). Analyzing V57I genotypes showed a higher homozygote Val/Val genotype in patients compared with controls (76% vs 68%), whereas the frequency of heterozygous Val/Ile genotype was lower in patients (17%) than controls (30%), yielding a marginal association between breast cancer and Val/Val genotype (P = .048). No association was observed between SNPs of either F31I or V57I genotypes and histological grades. However, there was a significant association between tumor stages and F31I genotype (P for trend = .003).This is the first report of F31I and V57I polymorphisms in AURKA gene in breast cancer in Iran. Determination of allelic polymorphism of those codons will help to understand background genetic predisposition and could have prognostic value in management of breast cancer in the target population.

Breast cancer metastases to the thyroid gland - an uncommon sentinel for diffuse metastatic disease: a case report and review of the literature.
Journal of medical case reports, 11(1):269.
BACKGROUND: Metastases to the thyroid are rare. The most common primary cancer to metastasize to the thyroid is renal cell carcinoma, followed by malignancies of the gastrointestinal tract, lungs, and skin, with breast cancer metastases to the thyroid being rare. Overall, the outcomes in malignancies that have metastasized to the thyroid are poor. There are no prospective studies addressing the role of surgery in metastatic disease of the thyroid. Isolated thyroidectomy has been proposed as a local disease control option to palliate and prevent the potential morbidity of tumor extension related to the airway. Here, we present a case of a patient with breast cancer metastases to the thyroid gland and discuss the role of thyroidectomy in the context of the current literature.
CASE PRESENTATION: A 62-year-old Afro-Caribbean woman was diagnosed as having bilateral breast carcinoma in 2004, for which she underwent bilateral mastectomy. The pathology revealed multifocal disease on the right, T2N0(0/20)M0 grade 1 and 2 invasive ductal carcinoma, and on the left side, T3N1(2/18)M0 grade 1 invasive ductal carcinoma. Surgery was followed by adjuvant chemotherapy and regional radiotherapy. The disease was under control on hormonal therapy until 2016, when she developed cervical lymphadenopathy. The fine-needle aspiration cytology of the thyroid was reported as papillary thyroid cancer; and the fine-needle biopsy of the left lateral nodal disease was more suggestive of breast malignancy. She underwent a total thyroidectomy and a clearance of the central compartment lymph nodes and a biopsy of the lateral nodal disease. The histopathological analysis was consistent with metastatic breast cancer in the thyroid and lymph nodes with no evidence of a primary thyroid malignancy.
CONCLUSIONS: A past history of a malignancy elsewhere should raise the index of suspicion of metastatic disease in patients presenting with thyroid lumps with or without cervical lymphadenopathy. Detection of metastases to the thyroid generally indicates poor prognosis, obviating the need of surgery in an already compromised patient. An empirical thyroidectomy should be considered in select patients for local disease control.

Integrated molecular analysis of Tamoxifen-resistant invasive lobular breast cancer cells identifies MAPK and GRM/mGluR signaling as therapeutic vulnerabilities.
Molecular and cellular endocrinology, 471:105-117.
Invasive lobular breast cancer (ILC) is an understudied malignancy with distinct clinical, pathological, and molecular features that distinguish it from the more common invasive ductal carcinoma (IDC). Mounting evidence suggests that estrogen receptor-alpha positive (ER+) ILC has a poor response to Tamoxifen (TAM), but the mechanistic drivers of this are undefined. In the current work, we comprehensively characterize the SUM44/LCCTam ILC cell model system through integrated analysis of gene expression, copy number, and mutation, with the goal of identifying actionable alterations relevant to clinical ILC that can be co-targeted along with ER to improve treatment outcomes. We show that TAM has several distinct effects on the transcriptome of LCCTam cells, that this resistant cell model has acquired copy number alterations and mutations that impinge on MAPK and metabotropic glutamate receptor (GRM/mGluR) signaling networks, and that pharmacological inhibition of either improves or restores the growth-inhibitory actions of endocrine therapy.

Podoplanin increases the migration of human fibroblasts and affects the endothelial cell network formation: A possible role for cancer-associated fibroblasts in breast cancer progression.
PloS one, 12(9):e0184970.
In our previous studies we showed that in breast cancer podoplanin-positive cancer-associated fibroblasts correlated positively with tumor size, grade of malignancy, lymph node metastasis, lymphovascular invasion and poor patients' outcome. Therefore, the present study was undertaken to assess if podoplanin expressed by fibroblasts can affect malignancy-associated properties of breast cancer cells. Human fibroblastic cell lines (MSU1.1 and Hs 578Bst) overexpressing podoplanin and control fibroblasts were co-cultured with breast cancer MDA-MB-231 and MCF7 cells and the impact of podoplanin expressed by fibroblasts on migration and invasiveness of breast cancer cells were studied in vitro. Migratory and invasive properties of breast cancer cells were not affected by the presence of podoplanin on the surface of fibroblasts. However, ectopic expression of podoplanin highly increases the migration of MSU1.1 and Hs 578Bst fibroblasts. The present study also revealed for the first time, that podoplanin expression affects the formation of pseudo tubes by endothelial cells. When human HSkMEC cells were co-cultured with podoplanin-rich fibroblasts the endothelial cell capillary-like network was characterized by significantly lower numbers of nodes and meshes than in co-cultures of endothelial cells with podoplanin-negative fibroblasts. The question remains as to how our experimental data can be correlated with previous clinical data showing an association between the presence of podoplanin-positive cancer-associated fibroblasts and progression of breast cancer. Therefore, we propose that expression of podoplanin by fibroblasts facilitates their movement into the tumor stroma, which creates a favorable microenvironment for tumor progression by increasing the number of cancer-associated fibroblasts, which produce numerous factors affecting proliferation, survival and invasion of cancer cells. In accordance with this, the present study revealed for the first time, that such podoplanin-mediated effects can affect tube formation by endothelial cells and participate in their pathological properties in the tumor context. Our experimental data were supported by clinical studies. First, when IDC and DCIS were analyzed by immunohistochemistry according to the presence of podoplanin-expressing cells, the numbers of cancer-associated fibroblasts with high expression of this glycoprotein were significantly higher in IDC than in DCIS cases. Second, using immunofluorescence, the co-localization of PDPN-positive CAFs with blood vessels stained with antibody directed against CD34 was observed in tumor stroma of IDC samples.

The Quest for more Research on Painful Diabetic Neuropathy.
Neuroscience, 387:28-37.
A 62-year-old diabetologist diagnosed himself to have diabetes type-2, with an HbA1c of 9.5. Five months after lifestyle intervention and a multi-drug approach, HbA1c was 6.3, systolic blood pressure was below 135mmHg and BMI reduced to 27. But he suffered from severe painful diabetic neuropathy. Therefore he decided to visit his friend, a famous neuroscientist at an even more famous university. He asked him several plain questions: 1. What is the natural course of painful diabetic neuropathy? 2. Why do I have, despite almost normalizing HbA1c, more problems than before? 3. Are you sure my problems are due to diabetes or should we do a nerve biopsy? 4. Are there imaging techniques helpful for the diagnosis of this diabetic complication, starting in the distal nerve endings of the foot and slowly moving ahead? 5. Can you suggest any drug, specific and effective, for relieving painful diabetic neuropathy? This review will use the experts' answers to the questions of the diabetologist, not only to give a summary of the current knowledge, but even more to highlight areas of research needed for improving the fate of patients with painful diabetic neuropathy. Based on the unknowns, which exceed the knowns in diabetic neuropathy, a quest for more public support of research is made.

Further evidence to demonstrate the significance of serum appearance of anti-p53 antibody as a marker for progressive potential in invasive ductal carcinoma of the breast.
The journal of medical investigation : JMI, 64(3.4):241-244.
BACKGROUND: Serum appearance of anti-p53 antibody (p53Ab) has been reported as an indicator for progressive potential of human tumor tumors including breast cancer. But its significance in breast cancer has not been discussed fully.
METHODS: Relationship between serum appearance of p53Abs and representative data accounting for progressive potential in breast cancer, nuclear grade (NG), triple negative cancer, and the cumulative score based on these two data (TGS) was investigated among 129 women with invasive ductal carcinoma (IDC) of the breast, who had been treated with surgical resection.
RESULTS: There was a significant correlation between appearance of p53Abs and recurrence of the tumors (P = 0.035). Significant correlation of serum appearance of p53Abs with negative expression of ER (P = 0.011), the proportion of TNBC (P = 0.013), NG (P = 0.017), and TGS (P = 0.0005).
CONCLUSIONS: Preoperative serum appearance of p53Abs can be correlated with pathological nuclear grade, incidence of triple negative breast cancer, and TGS. These results might demonstrate more powerful significance of serum appearance of p53Abs as an indicator of progressive potential in IDC of the breast. J. Med. Invest. 64: 241-244, August, 2017.

Tumori, 103(Suppl. 1):e5-e8 pii:3677046D-6264-43EF-89CD-2EC37EFC68CD.
INTRODUCTION:: NUT midline carcinoma (NMC) is a rare and aggressive epithelial cancer arising from median organs. It is driven by chromosomal translocation t(15;19) involving the rearrangement of NUT (nuclear protein in testis) and BRD4 (bromodomain 4) genes leading to fusion oncoprotein BRD4-NUT.
CASE PRESENTATION:: We report the case of a woman who was previously treated with induction chemotherapy, surgery, radiotherapy and adjuvant trastuzumab for HER-2 positive invasive ductal carcinoma of the breast. After 6 months of follow-up a lung nodule appeared. A biopsy showed an adenocarcinoma fetal type/lung blastoma, so a left inferior lobectomy was performed: NMC harboring BRD4-NUT rearrangement was diagnosed. After 9 months of follow-up, bone and soft tissue metastases occurred, so the patient was given radiotherapy. Next-generation sequencing technology identified somatic mutations in deleted in colorectal cancer (DCC), mixed lineage leukemia protein 3 (MLL3), and splicing factor 3B subunit 1 (SF3B1) genes in NMC cells from both primitive cancer and metastases. The patient was treated with the experimental BRD4 inhibitor for 10 months, until the disease progressed to the lung and bone. After spinal cord compression, the patient was offered palliative radiotherapy to bone and eventually died aged 39 years.
CONCLUSIONS:: To the best of our knowledge, our case is the first DCC, MLL3, and SF3B1 mutated NUT midline carcinoma reported in the literature. If these mutations were confirmed to play a role in this neoplasm, clinical trials analyzing targeted therapies should be considered, eg. colorectal cancer-like chemotherapies for DCC mutations, hypomethylating agents for MLL3 mutations or SF3B1 inhibitors in case of specific somatic mutations.

Correlation Between Expression of Twist and Podoplanin in Ductal Breast Carcinoma.
Anticancer research, 37(10):5485-5493.
BACKGROUND/AIM: As a result of activation of transcription factors engaged in epithelial-mesenchymal transition (EMT), such as Twist, inhibition of epithelial markers and an increased expression of mesenchymal markers are observed. One of the specific markers of cancer-associated fibroblasts is podoplanin (PDPN) - a mucin-type membrane glycoprotein. The aim of this work was to study the localisation and intensity of expression of Twist and PDPN on the mRNA and protein level in cases of invasive ductal breast carcinoma (IDC), and its association with patients' clinico-pathological data.
MATERIALS AND METHODS: The study included archival material in a form of 80 paraffin IDC blocks and 11 IDC fragments frozen in liquid nitrogen. Immunohistochemical expression of Twist and PDPN was evaluated using light microscope and semiquantitative scale for evaluation of nuclear expression or immunoreactive scale (IRS) for evaluation of cytoplasmic expression. Material was isolated from frozen IDC fragments using laser micro-dissection (from cancer and stromal cells, separately) and was used to perform real-time PCR.
RESULTS: Twist expression was higher in stromal cells in comparison to cancer cells. Analysis of patients' survival rate showed, that higher expression of Twist in cancer cells was associated with shorter overall survival time and shorter event-free survival time. The expression of PDPN was also higher in stromal cells in comparison with cancer cells. In addition, positive correlation was observed between expression of Twist and PDPN in stromal cells of IDC (r=0.267; p<0.05).
CONCLUSION: The relationship between the higher expression of Twist in both cancer and stromal cells and shorter patients' survival indicates Twist as a potential useful prognostic marker in IDC. Positive correlation of Twist and PDPN expression may indicate the role of PDPN in EMT in IDC.

CDH1 mutation screen in a BRCA1/2-negative familial breast-/ovarian cancer cohort.
Archives of gynecology and obstetrics, 297(1):147-152.
PURPOSE: Mutations in the CDH1 gene are linked both to diffuse gastric cancer and invasive lobular carcinoma (ILC). A high mutation rate is found in families fulfilling the diagnostic criteria for hereditary diffuse gastric cancer. Aim of this study was to clarify whether or not there is a significant contribution of CDH1 mutations in hereditary breast-/ovarian cancer (HBOC).
METHODS: Ninety-seven unrelated probands fulfilling the diagnostic criteria for HBOC (96 affected, 1 unaffected) but tested negative for pathogenic BRCA1/2 mutations were screened for CDH1 mutations by denaturing high performance liquid chromatography (DHPLC) and subsequent Sanger sequencing of suspicious and positive DHPLC results.
RESULTS: In total, we found two potentially pathogenic CDH1 alterations, c.1774G > A, pAla592Thr, and c.2512 A > G, p.Ser838Gly, classified as variants of unknown significance according to ClinVar. In addition, we detected a high number of known CDH1 polymorphisms (n = 62), some of them more frequent in patients with lobular (55%) than in those with invasive ductal carcinoma (27%).
CONCLUSION: Although none of the probands studied carried a clearly pathogenic CDH1 mutation, CDH1 could be considered a potential breast cancer gene, esp. for ILC worth including it in the NGS (next generation sequencing) HBOC panel.

The importance of early detection of calcifications associated with breast cancer in screening.
Breast cancer research and treatment, 167(2):451-458.
PURPOSE: The aim of this study was to assess how often women with undetected calcifications in prior screening mammograms are subsequently diagnosed with invasive cancer.
METHODS: From a screening cohort of 63,895 women, exams were collected from 59,690 women without any abnormalities, 744 women with a screen-detected cancer and a prior negative exam, 781 women with a false positive exam based on calcifications, and 413 women with an interval cancer. A radiologist identified cancer-related calcifications, selected by a computer-aided detection system, on mammograms taken prior to screen-detected or interval cancer diagnoses. Using this ground truth and the pathology reports, the sensitivity for calcification detection and the proportion of lesions with visible calcifications that developed into invasive cancer were determined.
RESULTS: The screening sensitivity for calcifications was 45.5%, at a specificity of 99.5%. A total of 68.4% (n = 177) of cancer-related calcifications that could have been detected earlier were associated with invasive cancer when diagnosed.
CONCLUSIONS: Screening sensitivity for detection of malignant calcifications is low. Improving the detection of these early signs of cancer is important, because the majority of lesions with detectable calcifications that are not recalled immediately but detected as interval cancer or in the next screening round are invasive at the time of diagnosis.

Ovarian Metastases of Breast Cancers With Signet Ring Cells: A Report of 17 Cases Including 14 Krukenberg Tumors.
International journal of gynecological pathology : official journal of the International Society of Gynecological Pathologists, 37(6):507-515.
Krukenberg tumor, defined as metastatic adenocarcinoma to the ovary containing at least 10% signet ring cells, usually arises from the stomach but can also originate from other sites. We reviewed 17 metastatic breast carcinomas to the ovary with signet ring cells to potentially identify features indicative of mammary origin as opposed to other possible primary sites. The patients ranged from 41 to 76 (mean, 53.6) yr. Fourteen had a prior history of invasive breast carcinoma (invasive ductal carcinoma, 4; invasive lobular carcinoma, 3; adenocarcinoma not otherwise specified, 3; carcinoma with ductal and lobular features, 2; and unspecified carcinoma, 2) and metastases were identified 2 to 284 (mean, 79) mo after the original diagnosis. Three patients had no known history of invasive breast carcinoma: 1 was subsequently diagnosed with invasive lobular carcinoma, 1 had suspicious bilateral breast masses identified on imaging, and 1 was lost to follow-up. Bilateral ovarian metastases were present in 87%, and the tumors ranged from 3.8 to 19 (mean, 8) cm. Microscopically the ovarian architecture was effaced in 71% by discrete tumor lobules separated by striking edema. The tumors exhibited a variety of histologic patterns: nests were most common (88%), followed by cords (82%), diffuse sheets (82%), single cells (71%), small clusters (41%), glands (29%), and follicle-like cysts (12%). Signet ring cells comprised 2% to 70% (mean, 33%) of the tumors, with 14 cases meeting the criteria for Krukenberg tumor. Signet ring cells were most frequently observed within diffuse sheets (71%) and cords (65%). Tumor cells arranged in nests, cords, and diffuse sheets are typical of Krukenberg tumor of breast origin, and the patterns recapitulate those seen in primary breast carcinomas. Features characteristic of gastrointestinal origin, such as extracellular mucin, intestinal-type glands, dirty necrosis, microcysts, and goblet cell carcinoid-like foci, were absent. The overall morphologic picture in cases of ovarian spread of breast cancer with signet ring cells is usually strongly suggestive of mammary origin. The diagnosis can be further supported by the clinical history and immunohistochemical evaluation.

Negative genic switch of HER-2 in the primary tumor instead of the synchronous metastatic nodal lesions after neoadjuvant chemotherapy in a patient with primary HER2-positive breast cancer.
World journal of surgical oncology, 15(1):189.
BACKGROUND: A few retrospective studies have indicated that neoadjuvant chemotherapy (NAC) in breast cancer may change biomarker profiles of the primary tumor. Little is known about the status of HER-2 gene of the synchronous nodal metastases when that of the residual tumor undergoes negative conversion in a neoadjuvant setting.
CASE PRESENTATION: We describe a female patient with left breast cancer (T2N2M0) who underwent negative conversion of HER-2 in the primary tumor instead of the synchronous nodal lesions after NAC. Core needle biopsy showed invasive ductal carcinoma with HER2 immunohistochemistry (IHC) (2+) and amplified HER-2 gene determined by fluorescence in situ hybridization (FISH). Then, the patient underwent 4 cycles of anthracycline- and taxane-based NAC and subsequent left modified radical mastectomy. Postoperative pathology showed invasive ductal carcinoma involving 4 of 12 surgically excised axillary lymph nodes with HER2 IHC (1+) and FISH negative (HER2 gene not amplified) in the residual tumor of the breast specimen. Due to the negative genic switch of HER2 after NAC, the patient rejected to accept trastuzumab. Under the patient's consent, the synchronous nodal lesions were further investigated and showed HER2 IHC(-) but FISH positive (HER-2 gene amplified). Therefore, the patient agreed to accept adjuvant trastuzumab treatment every 3 weeks for 1 year.
CONCLUSIONS: We propose further assessment of HER2 gene in the synchronous nodal metastases, especially when negative genic switch of HER-2 occurs in the primary tumor after NAC in order to tailor the systemic regimens for breast cancer patients.

Serum IGF-1 is associated with cognitive functions in early, drug-naïve Parkinson's disease.
PloS one, 12(10):e0186508.
OBJECTIVE: Cognitive deficits are common in Parkinson's disease (PD) since the early stages and many patients eventually develop dementia. Yet, occurrence of dementia in PD is unpredictable. Evidence supports the hypothesis that insulin-like growth factor-1 (IGF-1) is involved in cognitive deficits. Our aim was to evaluate the relationship between serum IGF-1 levels and neuropsychological scores in a large cohort of drug-naïve PD patients during the earliest stages of the disease.
METHODS: Serum IGF-1 levels were determined in 405 early, drug-naïve PD patients and 191 healthy controls (HC) enrolled in the Parkinson's Progression Markers Initiative (PPMI). The association between serum IGF-1 levels and neuropsychological scores was evaluated with linear regression analysis.
RESULTS: IGF-1 levels were similar in PD and HC. In PD patients the lowest IGF-1 quartile was a predictor of lower performances at the Semantic Fluency task (β = -3.46, 95%CI: -5.87 to -1.01, p = 0.005), the Symbol Digit Modalities Score (β = -2.09, 95%CI: -4.02 to -0.15, p = 0.034), and Hopkins Verbal Learning Test Retention (β = -0.05, 95%CI: -0.09 to -0.009, p = 0.019).
CONCLUSIONS: Lower serum IGF-1 levels are associated to poor performances in cognitive tasks assessing executive function, attention and verbal memory in a large cohort of early PD patients. Follow-up studies are warranted to assess if IGF-1 is related to the development of dementia in PD.

abstract = {OBJECTIVE: Cognitive deficits are common in Parkinson's disease (PD) since the early stages and many patients eventually develop dementia. Yet, occurrence of dementia in PD is unpredictable. Evidence supports the hypothesis that insulin-like growth factor-1 (IGF-1) is involved in cognitive deficits. Our aim was to evaluate the relationship between serum IGF-1 levels and neuropsychological scores in a large cohort of drug-naïve PD patients during the earliest stages of the disease.
METHODS: Serum IGF-1 levels were determined in 405 early, drug-naïve PD patients and 191 healthy controls (HC) enrolled in the Parkinson's Progression Markers Initiative (PPMI). The association between serum IGF-1 levels and neuropsychological scores was evaluated with linear regression analysis.
RESULTS: IGF-1 levels were similar in PD and HC. In PD patients the lowest IGF-1 quartile was a predictor of lower performances at the Semantic Fluency task (β = -3.46, 95%CI: -5.87 to -1.01, p = 0.005), the Symbol Digit Modalities Score (β = -2.09, 95%CI: -4.02 to -0.15, p = 0.034), and Hopkins Verbal Learning Test Retention (β = -0.05, 95%CI: -0.09 to -0.009, p = 0.019).

Androgen Receptor Expression and Bicalutamide Antagonize Androgen Receptor Inhibit β-Catenin Transcription Complex in Estrogen Receptor-Negative Breast Cancer.
Cellular physiology and biochemistry : international journal of experimental cellular physiology, biochemistry, and pharmacology, 43(6):2212-2225.
BACKGROUND/AIMS: Little is known about the potential mechanism of action for androgen receptor (AR) targeting treatment in estrogen receptor (ER)-negative breast cancer. This study aimed to evaluate AR status and its prognosis in four breast cancer subtypes. Bicalutamide has been identified as an AR antagonist and used for treating AR+/ER- breast cancer in a phase II trial. Our studies will clarify its mechanism in breast cancer treatment.
METHODS: A total of 510 consecutive cases of invasive ductal cancer (IDC) were evaluated in this study. The expression of AR was analyzed by immunohistochemistry and compared with patient survival, and its implications were evaluated in four subtypes of IDC. We examined bicalutamide as an AR antagonist to inhibit proliferation and increased apoptosis in AR+/ER- breast cancer cell lines. We explored the tumor suppressive functions of bicalutamide in vitro and vivo and its related mechanisms in AR+/ER- breast cancer.
RESULTS: AR expression was related to that of ER (P<0.001), PR (P<0.001), Her2 (P=0.017), Ki-67(P=0.020) and to four subtypes (P<0.001). AR retained independent prognostic signifcance (P=0.007, ER- cases; P=0.001, ER+ cases; P=0.001, total cases). We found that bicalutamide significantly decreased viability and increased apoptosis in vitro and vivo. The mechanistic analysis revealed that bicalutamide blocked androgen-stimulated oncogenic AR and Wnt/β-catenin signaling and inhibited the growth of AR+/ER- breast cancer.
CONCLUSION: Our studies provide novel insights into bicalutamide as an antagonist of AR function in AR+/ER- breast cancer and reveal the mechanistic basis for targeting AR as a therapeutic opportunity for patients with AR+/ER- breast cancer.

Invasive micropapillary carcinoma of the breast has a better long-term survival than invasive ductal carcinoma of the breast in spite of its aggressive clinical presentations: a comparison based on large population database and case-control analysis.
Cancer medicine, 6(12):2775-2786.
There are controversies in the comparison of overall survival between invasive micropapillary carcinoma of the breast (IMPC) and invasive ductal carcinoma (IDC). The objective of this study was to compare the long-term survival outcome between non-metastatic IMPC and IDC. The Surveillance, Epidemiology, and End Results database was searched to identify women with non-metastatic IMPC and IDC diagnosed between 2001 and 2013. Comparisons of patient and tumor characteristics were performed using Pearson's chi-square. The propensity score matching method was applied with each IMPC matched to one IDC. Breast cancer-specific survival (BCSS) and overall survival (OS) were estimated using the Kaplan-Meier product limit method and compared across groups using the log-rank statistic. Multivariate analysis was performed through Cox models. IMPC was presented with aggressive clinical presentations such as larger tumor, more positive lymph nodes, and more advanced stage compared with IDC. A higher rate of estrogen receptor (ER)/progesterone receptor (PR) positivity was also observed in IMPC. With a median follow-up of 64 months, IMPC had a better BCSS (P = 0.031) and OS (P = 0.012) compared with IDC. In a case-control analysis IMPC was still an independent favorable prognostic factor for BCSS (HR = 0.410, P < 0.001, 95% CI: 0.293-0.572) and OS (HR = 0.497, P < 0.001, 95% CI: 0.387-0.637). In subgroup analysis, IMPC always showed a better survival outcome compared with IDC except in AJCC stage I and histologic grade I disease. IMPC has a better long-term survival outcome compared with IDC in spite of its highly aggressive clinical presentation.

The Role of Molecular Testing in the Differential Diagnosis of Salivary Gland Carcinomas.
The American journal of surgical pathology, 42(2):e11-e27.
Salivary gland neoplasms are a morphologically heterogenous group of lesions that are often diagnostically challenging. In recent years, considerable progress in salivary gland taxonomy has been reached by the discovery of tumor type-specific fusion oncogenes generated by chromosome translocations. This review describes the clinicopathologic features of a selected group of salivary gland carcinomas with a focus on their distinctive genomic characteristics. Mammary analog secretory carcinoma is a recently described entity characterized by a t(12;15)(p13;q25) translocation resulting in an ETV6-NTRK3 fusion. Hyalinizing clear cell carcinoma is a low-grade tumor with infrequent nodal and distant metastasis, recently shown to harbor an EWSR1-ATF1 gene fusion. The CRTC1-MAML2 fusion gene resulting from a t(11;19)(q21;p13) translocation, is now known to be a feature of both low-grade and high-grade mucoepidermoid carcinomas associated with improved survival. A t(6;9)(q22-23;p23-34) translocation resulting in a MYB-NFIB gene fusion has been identified in the majority of adenoid cystic carcinomas. Polymorphous (low-grade) adenocarcinoma and cribriform adenocarcinoma of (minor) salivary gland origin are related entities with partly differing clinicopathologic and genomic profiles; they are the subject of an ongoing taxonomic debate. Polymorphous (low-grade) adenocarcinomas are characterized by hot spot point E710D mutations in the PRKD1 gene, whereas cribriform adenocarcinoma of (minor) salivary glands origin are characterized by translocations involving the PRKD1-3 genes. Salivary duct carcinoma (SDC) is a high-grade adenocarcinoma with morphologic and molecular features akin to invasive ductal carcinoma of the breast, including HER2 gene amplification, mutations of TP53, PIK3CA, and HRAS and loss or mutation of PTEN. Notably, a recurrent NCOA4-RET fusion has also been found in SDC. A subset of SDC with apocrine morphology is associated with overexpression of androgen receptors. As these genetic aberrations are recurrent they serve as powerful diagnostic tools in salivary gland tumor diagnosis, and therefore also in refinement of salivary gland cancer classification. Moreover, they are promising as prognostic biomarkers and targets of therapy.

The Epithelial-Mesenchymal Transition Pathway in Two Cases with Gastric Metastasis Originating from Breast Carcinoma, One with a Metachronous Primary Gastric Cancer.
Recent patents on anti-cancer drug discovery, 13(1):118-124.
BACKGROUND: Metastases to the stomach are extremely rare and the metastatic pathway is not well understood.
OBJECTIVE: To present two unusual gastric metastases and a review of the literature regarding the pathway of Epithelial Mesenchymal Transition (EMT) in the metastatic cells.
METHOD: The clinicopathological aspects of the two cases were presented in the light of the most recent patents. Data about patents were obtained from the online databases PubMed, World Intellectual Property Organization (WIPO) and Google patents.
RESULTS: In the first case, in a 73-year-old female, total gastrectomy was performed for a Gastric Cancer (GC) that was proved to be, based on the immunohistochemical features (positivity for mammaglobin and estrogen receptor and negativity for E-cadherin, β-catenin, CD44 and maspin), a metastasis from an invasive lobular carcinoma of the breast, that was later confirmed. In the second case, a 67-year-old female with invasive ductal carcinoma of the breast, which benefited from chemotherapy and mastectomy, presented a metachronous gastric adenocarcinoma with collision-type metastatic breast ductal carcinoma. The aggressiveness of the GC cells was induced through the E-cadherin/maspin pathway, while the CD44-related stem-like properties of the tumor cells induced the aggressiveness of ductal carcinoma.
CONCLUSION: In females with breast cancer, a possible metastasis in the stomach should be taken into account. Maspin and VSIG1 are not involved in breast cancer histogenesis. The Wnt/β-catenin signaling is not involved in the lobular carcinoma progression. The CD44/HER2 positivity in ductal carcinoma cells might indicate high risk of distant metastasis and low response to chemotherapy.

Maspin expression and subcellular localization in invasive ductal carcinoma of the breast: Prognostic significance and relation to microvessel density.
Journal of the Egyptian National Cancer Institute, 29(4):177-183.
Maspin (Mammary serine protease inhibitor) is a tumor suppressor serine. Its clinical significance and role in breast carcinoma are contradictory and inconclusive. Researches demonstrated that the function of maspin differs according to its subcellular localization. This study was conducted to investigate the expression of maspin in invasive ductal carcinoma (IDC) of the breast with special emphasis on its subcellular localization and to evaluate its prognostic role in relation to clinicopathological parameters and microvessel density (MVD) of the tumor. The expression of maspin was evaluated immunohistochemically in 45 IDC cases. The positive rate of maspin expression was 73.3%. Maspin positivity was significantly related to higher tumor grade (p value = 0.041), nodal metastasis (p value = 0.044), perineural invasion (p value = 0.047), and high CD34+MVD (p value = 0.002). Nuclear maspin was detected in 36.6% whereas cytoplasmic maspin was detected in 63.4% of maspin positive cases. A significant inverse relationship was observed between nuclear maspin and high tumor grade (p value = 0.016), and nodal metastasis (p value = 0.047). These results suggest that maspin expression has a prognostic role in breast cancer. Maspin expression is related to increased angiogenesis. Subcellular localization of maspin can strongly affect cancer prognosis. Cytoplasmic maspin relates to poor prognostic parameters whereas nuclear maspin relates to good prognostic ones.

Clinicopathological characteristics and survival outcomes in pleomorphic lobular breast carcinoma of the breast: a SEER population-based study.
Cancer medicine, 6(12):2867-2875.
The purpose of this study was to explore the clinicopathological features and survival outcome of pleomorphic lobular carcinoma (PLC) of breast, we identified 131 PLC patients and 460,109 invasive ductal carcinoma (IDC) patients in the Surveillance, Epidemiology, and End Result (SEER) database. PLCs presented with increased lymph node involvement, older age, higher AJCC stage and grade, and lower median survival months (PLC 84 ± 51.03 vs. IDC 105.2 ± 64.39 P < 0.01). Compared to IDC patients, PLC patients were more inclined to be treated with mastectomy. In univariate analysis, PLC patients showed a worse disease-specific survival (DSS) than that of IDC patients (hazard ratio = 0.691, 95% confidence interval 0.534-0.893, P < 0.01). In multivariate analysis, we took into account other prognostic factors and found that the histology types were no longer an independent prognostic factor (P = 0.120). DSS have no difference between matched IDC and PLC groups (P = 0.615). This result may be due to PLCs presenting higher tumor stage, higher tumor grade, and higher rate of LN metastasis than IDCs. Our conclusion is that PLC and IDC have many different characteristics, but there is not enough difference on the DSS.

EGFR conjunct FSCN1 as a Novel Therapeutic Strategy in Triple-Negative Breast Cancer.
Scientific reports, 7(1):15654.
Emerging evidence indicates that Fascin-1 (FSCN1) may possess a causal role in the development of several types of cancers and serves as a novel biomarker of aggressiveness in certain carcinomas. However, the regulatory mechanism of FSCN1 in triple-negative breast cancer (TNBC) cell invasion and migration is still largely unknown. In our study, we observed that the FSCN1 expression rates were significantly higher in invasive ductal carcinoma, compared with both usual ductal hyperplasia and ductal carcinoma in situ. FSCN1 expression was significantly higher in cases of TNBC compared with the non-TNBC subtype. Overexpression of FSCN1 promoted TNBC cell migration and invasion. Epidermal growth factor induced the expression of FSCN1 through activation of MAPK, which subsequently promoted cell migration and invasion. A significant decrease in FSCN1 expression following the co-treatment of FSCN1 siRNA and Gefitinib, compared with the separate treatment of FSCN1 siRNA or Gefitinib. Furthermore, we found that there was a significant association between FSCN1 expression and poor relapse-free survival and overall survival. Therefore, we suggest that co-targeting epidermal growth factor receptor and FSCN1 dual biomarker may be used as a novel therapeutic strategy for TNBC.

Factors affecting the under-diagnosis of atypical ductal hyperplasia diagnosed by core needle biopsies - A 10-year retrospective study and review of the literature.
International journal of surgery (London, England), 49:27-31.
INTRODUCTION: Due to the possibility of underestimation, surgical excision is usually offered to patients with atypical ductal hyperplasia (ADH) diagnosed with core needle biopsy (CNB). Here we review the 10-year data of patients with ADH diagnosed by CNB, aiming to identify the factors associated with under-diagnosis.
METHODS: Retrospective review of database from 1st Jan 2005 to 31st Dec 2014 was performed; patients with ADH diagnosed by CNB were identified. Diagnosis upgrade rate and its risk factors were evaluated.
RESULTS: 104 patients were found to have ADH on CNB, 101 patients received excisional biopsy while 3 patients refused operation. 34 patients had ductal carcinoma in situ (DCIS) after excision, 6 had invasive ductal carcinoma, 1 had lobular carcinoma in situ and 1 had angiosarcoma. CNB under-diagnosed up to 41.6% of malignant lesions. Breast mass on presentation and suspicious mammograms (BIRADS ≥ 4) are associated with diagnosis upgrade (P = 0.0005, 0.0001). Literature review of 39 studies between 1997 and 2017 revealed 3125 excision procedures performed for ADH diagnosed by CNB, the pooled median diagnosis upgrade rate was 25% (Range 4-54%).
CONCLUSION: We recommend excision in all patients with ADH diagnosed by CNB, especially in patients with suspicious mammographic features.

Activation of Yap1/Taz signaling in ischemic heart disease and dilated cardiomyopathy.
Experimental and molecular pathology, 103(3):267-275.
Genetic manipulation of key components of the evolutionally conserved Hippo pathway has shown that the precise control of these signaling molecules is critical to cardiac development and response to stresses. However, how this pathway is involved in the progression of cardiac dysfunction in different heart diseases remains unclear. We investigated the expressional levels and subcellular localization of Yap1, Taz, and Tead1 and determined Hippo target gene expression in failing human hearts with ischemic heart disease (IHD) and idiopathic dilated cardiomyopathy (IDC) and mouse desmin-related cardiomyopathy (DES). Our results demonstrated that Yap1, Taz, and Tead1 were significantly increased in failing human and DES hearts compared with the non-failing controls (NFH) or wild type (WT) mouse hearts at both mRNA and protein levels. Interestingly, adult human and mouse hearts had more Taz than Yap1 by mRNA and protein expression and their increases in diseased hearts were proportional and did not change Yap1/Taz ratio. Yap1, Taz, and Tead1 were accumulated in the nuclear fraction and cardiomyocyte nuclei of diseased hearts. The ratio of Yap1 phosphorylated at serine 127 (human) or serine 112 (mouse) to the total Yap1 (pYap1/Yap1) was significantly lower in the nuclear fraction of diseased hearts than that in normal controls. More importantly, Hippo downstream targets Ankrd1, Ctgf, and Cyr61 were transcriptionally elevated in the diseased hearts. These results suggest that Yap1/Taz signaling is activated in human and mouse dysfunctional hearts. Further investigation with relevant animal models will determine whether this pathway is a potential target for preventing and reversing abnormal remodeling during the progression of different cardiac disorders.

Visual biofeedback using transperineal ultrasound in second stage of labor.
Ultrasound in obstetrics & gynecology : the official journal of the International Society of Ultrasound in Obstetrics and Gynecology, 52(1):91-96.
OBJECTIVE: To assess the obstetric and psychological effects of visual biofeedback by transperineal ultrasound (TPU) during the second stage of labor.
METHODS: This was a prospective, single-center observational study of low-risk nulliparous women with epidural analgesia undergoing vaginal delivery. Visual biofeedback using TPU was provided to 26 women during the second stage of labor. Pushing efficacy was assessed by the change in the angle of progression (AoP) at rest and during pushing efforts, before and after biofeedback. Obstetric outcomes included incidence of perineal tearing, mode of delivery and length of second stage of labor. Psychological outcomes were assessed by self-reported measures obtained during the postnatal hospital stay and included measures of perceived control and maternal satisfaction with childbirth, as well as level of maternal feelings of connectedness with the newborn. Obstetric and psychological results were compared with those of a control group of 69 women who received standard obstetric coaching from midwives.
RESULTS: Pushing efficacy increased significantly following visual biofeedback by TPU (P = 0.01), as indicated by a significantly lower delta AoP before (mean, 22.2° (95% CI, 13.9-31.7°)) compared with after (mean, 35.2° (95% CI, 25.9-45.3°)) biofeedback. A significant association was found between visual biofeedback and an intact perineum following delivery (P = 0.03). No significant differences were found between the two groups with regard to mode of delivery or length of the second stage. Feelings of maternal connectedness with the newborn were significantly stronger (P = 0.003) in women who received visual biofeedback than in those who did not. However, perceived control during childbirth and maternal satisfaction with childbirth did not differ significantly between the biofeedback and control groups.
CONCLUSIONS: This pilot study suggests that biofeedback using TPU may serve as a complementary tool to coached maternal pushing during the second stage of labor, with obstetric as well as psychological benefits. Further studies are required to confirm our findings and define the optimal duration of the intervention. Copyright © 2017 ISUOG. Published by John Wiley & Sons Ltd.

Attenuated psychosis and basic self-disturbance as risk factors for depression and suicidal ideation/behaviour in community-dwelling adolescents.
Early intervention in psychiatry, 13(3):532-538.
BACKGROUND AND AIMS: Adolescents at clinical high risk (CHR) for psychosis, as defined by the presence of attenuated psychosis symptoms (APS), exhibit increased levels of suicidal ideation and behaviour. However, no research thus far has examined the link between basic self-disturbances (SDs), an established marker for CHR, and suicidality/self-harm in this population. The goal of this pilot study was to assess the association between SD, depression and suicidal ideation and behaviour among non-help-seeking adolescents from the community.
METHOD: A total of 100 community-dwelling adolescents (age range: 13-16) were assessed using the Examination of Anomalous Self-experience, Prodromal Questionnaire, Structured Interview for Prodromal Syndromes, Mood and Anxiety Symptom Questionnaire and the Schedule for Affective Disorders and Schizophrenia for School-Age Children (K-SADS). The K-SADS was used to derive a binary diagnosis of unipolar depression, as well as to measure suicidal ideation and behaviour and self-harm.
RESULTS: In a multiple regression analysis, SD accounted for variance in depressive symptoms and suicidality/self-harm over and above that accounted for by APS. Moreover, SD accounted for variance in suicidality/self-harm over and above that accounted for by depression symptoms.
CONCLUSIONS: These pilot results suggest that SD might be a unique dimension of vulnerability to depression and suicidality/self-harm in adolescence. Also, they encourage assessment of SD as part of a suicide risk assessment, particularly in the context of risk for subsequent psychosis.

Long Non-Coding RNAs in Metabolic Organs and Energy Homeostasis.
International journal of molecular sciences, 18(12):.
Single cell organisms can surprisingly exceed the number of human protein-coding genes, which are thus not at the origin of the complexity of an organism. In contrast, the relative amount of non-protein-coding sequences increases consistently with organismal complexity. Moreover, the mammalian transcriptome predominantly comprises non-(protein)-coding RNAs (ncRNA), of which the long ncRNAs (lncRNAs) constitute the most abundant part. lncRNAs are highly species- and tissue-specific with very versatile modes of action in accordance with their binding to a large spectrum of molecules and their diverse localization. lncRNAs are transcriptional regulators adding an additional regulatory layer in biological processes and pathophysiological conditions. Here, we review lncRNAs affecting metabolic organs with a focus on the liver, pancreas, skeletal muscle, cardiac muscle, brain, and adipose organ. In addition, we will discuss the impact of lncRNAs on metabolic diseases such as obesity and diabetes. In contrast to the substantial number of lncRNA loci in the human genome, the functionally characterized lncRNAs are just the tip of the iceberg. So far, our knowledge concerning lncRNAs in energy homeostasis is still in its infancy, meaning that the rest of the iceberg is a treasure chest yet to be discovered.

Moreover, the mammalian transcriptome predominantly comprises non-(protein)-coding RNAs (ncRNA), of which the long ncRNAs (lncRNAs) constitute the most abundant part. lncRNAs are highly species- and tissue-specific with very versatile modes of action in accordance with their binding to a large spectrum of molecules and their diverse localization. lncRNAs are transcriptional regulators adding an additional regulatory layer in biological processes and pathophysiological conditions. Here, we review lncRNAs affecting metabolic organs with a focus on the liver, pancreas, skeletal muscle, cardiac muscle, brain, and adipose organ. In addition, we will discuss the impact of lncRNAs on metabolic diseases such as obesity and diabetes. In contrast to the substantial number of lncRNA loci in the human genome, the functionally characterized lncRNAs are just the tip of the iceberg. So far, our knowledge concerning lncRNAs in energy homeostasis is still in its infancy, meaning that the rest of the iceberg is a treasure chest yet to be discovered.},

The NADPH organizers NoxO1 and p47phox are both mediators of diabetes-induced vascular dysfunction in mice.
Redox biology, 15:12-21.
AIM: NADPH oxidases are important sources of reactive oxygen species (ROS). Several Nox homologues are present together in the vascular system but whether they exhibit crosstalk at the activity level is unknown. To address this, vessel function of knockout mice for the cytosolic Nox organizer proteins p47phox, NoxO1 and a p47phox-NoxO1-double knockout were studied under normal condition and during streptozotocin-induced diabetes.
RESULTS: In the mouse aorta, mRNA expression for NoxO1 was predominant in smooth muscle and endothelial cells, whereas p47phox was markedly expressed in adventitial cells comprising leukocytes and tissue resident macrophages. Knockout of either NoxO1 or p47phox resulted in lower basal blood pressure. Deletion of any of the two subunits also prevented diabetes-induced vascular dysfunction. mRNA expression analysis by MACE (Massive Analysis of cDNA ends) identified substantial gene expression differences between the mouse lines and in response to diabetes. Deletion of p47phox induced inflammatory activation with increased markers of myeloid cells and cytokine and chemokine induction. In contrast, deletion of NoxO1 resulted in an attenuated interferon gamma signature and reduced expression of genes related to antigen presentation. This aspect was also reflected by a reduced number of circulating lymphocytes in NoxO1-/- mice.
INNOVATION AND CONCLUSION: ROS production stimulated by NoxO1 and p47phox limit endothelium-dependent relaxation and maintain blood pressure in mice. However, NoxO1 and p47phox cannot substitute each other despite their similar effect on vascular function. Deletion of NoxO1 induced an anti-inflammatory phenotype, whereas p47phox deletion rather elicited a hyper-inflammatory response.

Expression of GHRH-R, a Potentially Targetable Biomarker, in Triple-negative Breast Cancer.
Applied immunohistochemistry & molecular morphology : AIMM, 26(1):1-5.
PURPOSE: Growth hormone-releasing hormone (GHRH) has been shown to modify the growth behavior of many cancers, including breast. GHRH is produced by tumor cells, acts in an autocrine/paracrine manner, and requires the presence of GHRH receptor (GHRH-R) on the tumor cells to exert its effects. GHRH activity can be effectively blocked by synthetic antagonists of its receptor and hence, the expression of GHRH-R by tumor cells could serve as a predictor of response to GHRH-R antagonist therapy. In this study, we investigated the expression of GHRH-R in triple-negative breast cancers (TNBC). As TNBCs are morphologically and immunophenotypically heterogenous, the staining results were also correlated with the histologic subtypes of these tumors.
MATERIALS AND METHODS: On the basis of histomorphology and immunophenotype, 134 cases of primary TNBCs were further subdivided into medullary, metaplastic, apocrine, and invasive ductal carcinomas of no special type (IDC-NST). Immunohistochemistry for GHRH-R was performed on paraffin sections and the staining results were assessed semiquantitatively as negative, low expression, moderate, and high expression.
RESULTS: Of the 134 TNBCs, 85 were classified as IDC-NST, 25 as metaplastic, 16 as medullary, and 8 as apocrine carcinoma. Overall, positive reaction for GHRH-R was seen in 77 (57%) of tumors including 66 (77.6%) of IDC-NST. All medullary carcinomas were negative for GHRH-R and, with the exception of 1 case with low expression, none of the metaplastic carcinomas expressed GHRH-R (P<0.005).
CONCLUSIONS: A considerable number of TNBCs are positive for GHRH-R as a predictor of potential response to anti-GHRH-R treatment. This expression however, varies considerably between histologic subtypes of triple-negative breast cancers. Although most medullary and metaplastic carcinomas do not express GHRH-R, three fourths of the IDC-NST show a positive reaction. Testing for GHRH-R expression is therefore advisable if anti-GHRH-R therapy is being considered.

Inhibition of fucosylation in human invasive ductal carcinoma reduces E-selectin ligand expression, cell proliferation, and ERK1/2 and p38 MAPK activation.
Molecular oncology, 12(5):579-593.
Breast cancer tissue overexpresses fucosylated glycans, such as sialyl-Lewis X/A (sLe[X][/A]), and α-1,3/4-fucosyltransferases (FUTs) in relation to increased disease progression and metastasis. These glycans in tumor circulating cells mediate binding to vascular E-selectin, initiating tumor extravasation. However, their role in breast carcinogenesis is still unknown. Here, we aimed to define the contribution of the fucosylated structures, including sLe[X][/A] , to cell adhesion, cell signaling, and cell proliferation in invasive ductal carcinomas (IDC), the most frequent type of breast cancer. We first analyzed expression of E-selectin ligands in IDC tissue and established primary cell cultures from the tissue. We observed strong reactivity with E-selectin and anti-sLe[X][/A] antibodies in both IDC tissue and cell lines, and expression of α-1,3/4 FUTs FUT4, FUT5, FUT6, FUT10, and FUT11. To further assess the role of fucosylation in IDC biology, we immortalized a primary IDC cell line with human telomerase reverse transcriptase to create the 'CF1_T cell line'. Treatment with 2-fluorofucose (2-FF), a fucosylation inhibitor, completely abrogated its sLe[X][/A] expression and dramatically reduced adherence of CF1_T cells to E-selectin under hemodynamic flow conditions. In addition, 2-FF-treated CF1_T cells showed a reduced migratory ability, as well as decreased cell proliferation rate. Notably, 2-FF treatment lowered the growth factor expression of CF1_T cells, prominently for FGF2, vascular endothelial growth factor, and transforming growth factor beta, and negatively affected activation of signal-regulating protein kinases 1 and 2 and p38 mitogen-activated protein kinase signaling pathways. These data indicate that fucosylation licenses several malignant features of IDC, such as cell adhesion, migration, proliferation, and growth factor expression, contributing to tumor progression.

High PD-L1/CD86 MFI ratio and IL-10 secretion characterize human regulatory dendritic cells generated for clinical testing in organ transplantation.
Cellular immunology, 323:9-18.
Human regulatory dendritic cells (DCreg) were generated from CD14 immunobead-purified or elutriated monocytes in the presence of vitamin D3 and IL-10. They exhibited similar, low levels of costimulatory CD80 and CD86, but comparatively high levels of co-inhibitory programed death ligand-1 (PD-L1) and IL-10 production compared to control immature DC (iDC). Following Toll-like receptor 4 ligation, unlike control iDC, DCreg resisted phenotypic and functional maturation and further upregulated PD-L1:CD86 expression. Whereas LPS-stimulated control iDC (mature DC; matDC) secreted pro-inflammatory tumor necrosis factor but no IL-10, the converse was observed for LPS-stimulated DCreg. DCreg weakly stimulated naïve and memory allogeneic CD4[+] and CD8[+] T cell proliferation and IFNγ, IL-17A and perforin/granzyme B production in MLR. Their stimulatory function was enhanced however, by blocking PD-1 ligation. High-throughput T cell receptor (TCR) sequencing revealed that, among circulating T cell subsets, memory CD8[+] T cells contained the most alloreactive TCR clonotypes and that, while matDC expanded these alloreactive memory CD8 TCR clonotypes, DCreg induced more attenuated responses. These findings demonstrate the feasibility of generating highly-purified GMP-grade DCreg for systemic infusion, their influence on the alloreactive T cell response, and a key mechanistic role of the PD1 pathway.

A proteolytic fragment of histone deacetylase 4 protects the heart from failure by regulating the hexosamine biosynthetic pathway.
Nature medicine, 24(1):62-72.
The stress-responsive epigenetic repressor histone deacetylase 4 (HDAC4) regulates cardiac gene expression. Here we show that the levels of an N-terminal proteolytically derived fragment of HDAC4, termed HDAC4-NT, are lower in failing mouse hearts than in healthy control hearts. Virus-mediated transfer of the portion of the Hdac4 gene encoding HDAC4-NT into the mouse myocardium protected the heart from remodeling and failure; this was associated with decreased expression of Nr4a1, which encodes a nuclear orphan receptor, and decreased NR4A1-dependent activation of the hexosamine biosynthetic pathway (HBP). Conversely, exercise enhanced HDAC4-NT levels, and mice with a cardiomyocyte-specific deletion of Hdac4 show reduced exercise capacity, which was characterized by cardiac fatigue and increased expression of Nr4a1. Mechanistically, we found that NR4A1 negatively regulated contractile function in a manner that depended on the HBP and the calcium sensor STIM1. Our work describes a new regulatory axis in which epigenetic regulation of a metabolic pathway affects calcium handling. Activation of this axis during intermittent physiological stress promotes cardiac function, whereas its impairment in sustained pathological cardiac stress leads to heart failure.

miRNAs as Biomarkers for Predicting the Progression of Ductal Carcinoma in Situ.
The American journal of pathology, 188(3):542-549.
Ductal carcinoma in situ (DCIS) is defined as a proliferation of neoplastic cells within the duct of the mammary gland that have not invaded into the surrounding stroma. DCIS is considered a precursor to invasive ductal carcinoma (IDC); however, approximately half of DCIS may progress to IDC, if left untreated. Current research has shown that the genomic and transcriptomic changes are present in DCIS before the emergence of invasive disease, indicating that the malignant nature of the DCIS is defined before invasion. However, important questions remain surrounding the specific changes and processes required for malignant progression and identification of prognostic indicators of aggressiveness. miRNAs are small regulatory RNAs that can modulate gene expression by complementary binding to target mRNAs and inducing translational repression and/or mRNA degradation. In the past decade, research has shown that miRNA expression is dysregulated in IDC and that these changes are already present at the DCIS stage. Therefore, changes in miRNA expression may provide the necessary information to identify a clinical indicator of the aggressiveness of DCIS. Herein, we review the miRNA signatures identified in DCIS, describe how these signatures may be used to predict the aggressiveness of DCIS, and discuss future perspectives for DCIS biomarker discovery.

BACKGROUND: Wild type p53-induced phosphatase 1 (Wip1), encoded by the protein phosphatase magnesium dependent 1 delta (PPM1D), inhibits p53. PPM1D amplification has been reported in breast cancer. Breast cancer can sometimes develop without a tumor protein 53 (TP53) mutation. In these cases, the p53 pathway might be disrupted by alternative mechanisms, and Wip1 is reported to be a key molecule involved.
MATERIALS AND METHODS: Primary invasive ductal carcinoma specimens were obtained from 201 cases, for which archival tissue samples for immunohistochemistry were available. We evaluated Wip1 and p21 protein expression (201 cases), Wip1 mRNA expression (63 cases), PPM1D DNA copy number (71 cases) and TP53 status (36 cases) using available samples among the 201 cases, and analyzed their relationships with clinicopathological factors and prognosis.
RESULTS: The nuclear expression of Wip1 protein was positive in 21 cases (10.4%). The PPM1D DNA copy number was significantly correlated with Wip1 protein expression. All cases with PPM1D amplification by single-nucleotide polymorphism comparative genomic hybridization array showed positive nuclear Wip1 expression. Wip1 protein expression was positively correlated with p21 expression. The tumors with positive Wip1 and negative p21 expression showed the poorest prognosis among all tumor types.
CONCLUSION: The protein expression of Wip1 might be regulated by PPM1D amplification, independent of TP53 status. Positive Wip1 and negative p21 expression was associated with the poorest prognosis and suggests the loss of p53 function.

Induction of human tolerogenic dendritic cells by 3'-sialyllactose via TLR4 is explained by LPS contamination.
Glycobiology, 28(3):126-130.
The human milk oligosaccharide 3'-sialyllactose (3'SL) has previously been shown to activate murine dendritic cells (DC) in a Toll-like receptor (TLR) 4-mediated manner ex vivo. In this study we aimed to investigate whether 3'SL has similar immunomodulatory properties on human DC. 3'SL was shown to induce NF-κB activation via human TLR4. However, LPS was detected in the commercially obtained 3'SL from different suppliers. After the removal of LPS from 3'SL, we studied its ability to modify DC differentiation in vitro. In contrast to LPS and 3'SL, LPS-free 3'SL did not induce functional and phenotypical changes on immature DC (iDC). iDC that were differentiated in the presence of LPS or 3'SL showed a semi-mature phenotype (i.e., fewer CD83+CD86+ DC), produced IL-10 and abrogated IL-12p70 and tumor necrosis factor-alpha levels upon stimulation with several TLR ligands. Differentiation into these tolerogenic DC was completely abrogated by LPS removal from 3'SL. In contrast to previous reports in mice, we found that LPS-free 3'SL does not activate NF-κB via human TLR4. In conclusion, removing LPS from (oligo)saccharide preparations is necessary to study their potential immunomodulatory function.

Invasive micropapillary carcinoma of the breast overexpresses MUC4 and is associated with poor outcome to adjuvant trastuzumab in HER2-positive breast cancer.
BMC cancer, 17(1):895.
BACKGROUND: Invasive micropapillary carcinoma of the breast (IMPC) is a histological tumor variant that occurs with low frequency characterized by an inside-out formation of tumor clusters with a pseudopapillary arrangement. IMPC is an aggressive tumor with poor clinical outcome. In addition, this histological subtype usually expresses human epidermal growth factor receptor 2 (HER2) which also correlates with a more aggressive tumor. In this work we studied the clinical significance of IMPC in HER2-positive breast cancer patients treated with adjuvant trastuzumab. We also analyzed mucin 4 (MUC4) expression as a novel biomarker to identify IMPC.
METHODS: We retrospectively studied 86 HER2-positive breast cancer patients treated with trastuzumab and chemotherapy in the adjuvant setting. We explored the association of the IMPC component with clinicopathological parameters at diagnosis and its prognostic value. We compared MUC4 expression in IMPC with respect to other histological breast cancer subtypes by immunohistochemistry.
RESULTS: IMPC, either as a pure entity or associated with invasive ductal carcinoma (IDC), was present in 18.6% of HER2-positive cases. It was positively correlated with estrogen receptor expression and tumor size and inversely correlated with patient's age. Disease-free survival was significantly lower in patients with IMPC (hazard ratio = 2.6; 95%, confidence interval 1.1-6.1, P = 0.0340). MUC4, a glycoprotein associated with metastasis, was strongly expressed in all IMPC cases tested. IMPC appeared as the histological breast cancer subtype with the highest MUC4 expression compared to IDC, lobular and mucinous carcinoma.
CONCLUSION: In HER2-positive breast cancer, the presence of IMPC should be carefully examined. As it is often not informed, because it is relatively difficult to identify or altogether overlooked, we propose MUC4 expression as a useful biomarker to highlight IMPC presence. Patients with MUC4-positive tumors with IMPC component should be more frequently monitored and/or receive additional therapies.

Analysis of Immune Cells in Single Sciatic Nerves and Dorsal Root Ganglion from a Single Mouse Using Flow Cytometry.
Journal of visualized experiments : JoVE.
Nerve-resident immune cells in the peripheral nervous system (PNS) are essential to maintaining neuronal integrity in a healthy nerve. The immune cells of the PNS are affected by injury and disease, affecting the nerve function and the capacity for regeneration. Neuronal immune cells are commonly analyzed by immunofluorescence (IF). While IF is essential for determining the location of the immune cells in the nerve, IF is only semi-quantitative and the method is limited to the number of markers that can be analyzed simultaneously and the degree of surface expression. In this study, flow cytometry was used for quantitative analysis of leukocyte infiltration into sciatic nerves or dorsal root ganglions (DRGs) of individual mice. Single cell analysis was performed using DAPI and several proteins were analyzed simultaneously for either surface or intracellular expression. Both sciatic nerves from one mouse that were treated according to this protocol generated ≥ 30,000 single nucleated events. The proportion of leukocytes in the sciatic nerves, determined by expression of CD45, was approximately 5% of total cell content in the sciatic nerve and approximately 5-10% in the DRG. Although this protocol focuses primarily on the immune cell population within the PNS, the flexibility of flow cytometry to measure a number of markers simultaneously means that the other cells populations present within the nerve, such as Schwann cells, pericytes, fibroblasts, and endothelial cells, can also be analyzed using this method. This method therefore provides a new means for studying systemic effects on the PNS, such as neurotoxicology and genetic models of neuropathy or in chronic diseases, such as diabetes.

Cribriform and intraductal prostate cancer are associated with increased genomic instability and distinct genomic alterations.
BMC cancer, 18(1):8.
BACKGROUND: Invasive cribriform and intraductal carcinoma (CR/IDC) is associated with adverse outcome of prostate cancer patients. The aim of this study was to determine the molecular aberrations associated with CR/IDC in primary prostate cancer, focusing on genomic instability and somatic copy number alterations (CNA).
METHODS: Whole-slide images of The Cancer Genome Atlas Project (TCGA, N = 260) and the Canadian Prostate Cancer Genome Network (CPC-GENE, N = 199) radical prostatectomy datasets were reviewed for Gleason score (GS) and presence of CR/IDC. Genomic instability was assessed by calculating the percentage of genome altered (PGA). Somatic copy number alterations (CNA) were determined using Fisher-Boschloo tests and logistic regression. Primary analysis were performed on TCGA (N = 260) as discovery and CPC-GENE (N = 199) as validation set.
RESULTS: CR/IDC growth was present in 80/260 (31%) TCGA and 76/199 (38%) CPC-GENE cases. Patients with CR/IDC and ≥ GS 7 had significantly higher PGA than men without this pattern in both TCGA (2.2 fold; p = 0.0003) and CPC-GENE (1.7 fold; p = 0.004) cohorts. CR/IDC growth was associated with deletions of 8p, 16q, 10q23, 13q22, 17p13, 21q22, and amplification of 8q24. CNAs comprised a total of 1299 gene deletions and 369 amplifications in the TCGA dataset, of which 474 and 328 events were independently validated, respectively. Several of the affected genes were known to be associated with aggressive prostate cancer such as loss of PTEN, CDH1, BCAR1 and gain of MYC. Point mutations in TP53, SPOP and FOXA1were also associated with CR/IDC, but occurred less frequently than CNAs.
CONCLUSIONS: CR/IDC growth is associated with increased genomic instability clustering to genetic regions involved in aggressive prostate cancer. Therefore, CR/IDC is a pathologic substrate for progressive molecular tumour derangement.

Multiclonal Invasion in Breast Tumors Identified by Topographic Single Cell Sequencing.
Cell, 172(1-2):205-217.e12.
Ductal carcinoma in situ (DCIS) is an early-stage breast cancer that infrequently progresses to invasive ductal carcinoma (IDC). Genomic evolution has been difficult to delineate during invasion due to intratumor heterogeneity and the low number of tumor cells in the ducts. To overcome these challenges, we developed Topographic Single Cell Sequencing (TSCS) to measure genomic copy number profiles of single tumor cells while preserving their spatial context in tissue sections. We applied TSCS to 1,293 single cells from 10 synchronous patients with both DCIS and IDC regions in addition to exome sequencing. Our data reveal a direct genomic lineage between in situ and invasive tumor subpopulations and further show that most mutations and copy number aberrations evolved within the ducts prior to invasion. These results support a multiclonal invasion model, in which one or more clones escape the ducts and migrate into the adjacent tissues to establish the invasive carcinomas.

Triple negative breast cancer: A clinico-epidemiological and histopronostic study of 90 cases.
La Tunisie medicale, 95(1):37-44.
PURPOSE: The aim of this study was to describe the clinico-epidemiological and histopronostic characteristics of triple negative breast cancer (TNBC) and to evaluate the therapeutic results in tunisian women.
METHODS: We reported the results of a retrospective study including 90 patients treated for TNBC between Junuary 2008 and December 2009 in the Salah Azaiz Institute of Tunis.
RESULTS: TNBCoccured in 14% of diagnosed breast cancers. The mean age at diagnosis was 53.67 years. Family history of breast cancer was reported in 10% of cases.The majority of tumors were classified as T2 (41%) and associated with invasive ductal carcinoma histological type (99%) and SBR grade-II (54%). Tumor lymph node metastases were detected in 44% of patients.Among operated patients, 46% of patients underwent conservative surgery and 54% radical surgery. Chemotherapy and postoperative radiotherapy were given in97% and 80%of patients, respectively. After a median follow-up of 33.51 months, 61% of patients remained free of disease, 12% hadloco-regional recurrence, 9% had disease progression during chemotherapy and 21% developed systemic disease.
CONCLUSION: TNBC diagnosis is often made in the advanced stage and has a tendency to recur after treatment. The variable responseto chemotherapy is due to the molecular tumor heterogeneity. The development of targeted therapies is necessary to improve outcome of chemoresistant TNBC.

abstract = {PURPOSE: The aim of this study was to describe the clinico-epidemiological and histopronostic characteristics of triple negative breast cancer (TNBC) and to evaluate the therapeutic results in tunisian women.
METHODS: We reported the results of a retrospective study including 90 patients treated for TNBC between Junuary 2008 and December 2009 in the Salah Azaiz Institute of Tunis.
RESULTS: TNBCoccured in 14% of diagnosed breast cancers. The mean age at diagnosis was 53.67 years. Family history of breast cancer was reported in 10% of cases.The majority of tumors were classified as T2 (41%) and associated with invasive ductal carcinoma histological type (99%) and SBR grade-II (54%). Tumor lymph node metastases were detected in 44% of patients.Among operated patients, 46% of patients underwent conservative surgery and 54% radical surgery. Chemotherapy and postoperative radiotherapy were given in97% and 80%of patients, respectively. After a median follow-up of 33.51 months, 61% of patients remained free of disease, 12% hadloco-regional recurrence, 9% had disease progression during chemotherapy and 21% developed systemic disease.
CONCLUSION: TNBC diagnosis is often made in the advanced stage and has a tendency to recur after treatment. The variable responseto chemotherapy is due to the molecular tumor heterogeneity. The development of targeted therapies is necessary to improve outcome of chemoresistant TNBC.},

Role of nestin expression in angiogenesis and breast cancer progression.
International journal of oncology, 52(2):527-535.
Nestin is an intermediate filament protein and a stem cell marker expressed in several tumours. There is growing evidence of an association between the expression level of nestin and the pathogenesis of triple-negative breast cancer (TNBC). Nestin is also expressed in newly forming tumour vessels and is a valuable marker of ongoing angiogenesis. In this study, we aimed to evaluate the prognostic value of nestin expression in breast tumour cells and to determine whether this expression influences angiogenesis. Immunohistochemical (IHC) analyses were carried out on 124 cases of invasive ductal carcinoma (IDC) of the breast with a panel of murine monoclonal antibodies against nestin, CD31, CD34, SOX-18 and Ki‑67. We evaluated nestin expression in tumour and endothelial cells, Ki‑67 in tumour cells, and CD31, CD34 and SOX-18 in endothelial cells. Our results demonstrated that nestin expression in tumour cells correlated with the area and number of vessels expressing nestin, CD31, CD34 and SOX-18. We also found a positive correlation between nestin-expressing vessels and SOX-18-expressing vessels. Our results are consistent with those of previous studies, in which nestin expression in endothelial cells was shown to be strongly associated with triple-negative subtype, poorly differentiated G3 tumours, a higher proliferation index and a shorter overall survival. Nestin expression was also examined in human breast cancer cell lines (MCF-7, SK-BR-3, MDA‑MB‑231 and BO2 cells) representing a different level of tumour aggressiveness and reflecting histological grade. A higher nestin protein level was observed in more aggressive MDA‑MB‑231 and BO2 cells than in MCF-7 and SK-BR-3 cells.

The PPARγ agonist efatutazone delays invasive progression and induces differentiation of ductal carcinoma in situ.
Breast cancer research and treatment, 169(1):47-57.
PURPOSE: Ductal carcinoma in situ (DCIS) is a pre-invasive lesion of the breast considered a precursor of invasive ductal carcinoma. This study aimed to determine whether activated PPARγ acts as a tumor suppressor in human DCIS progression.
METHODS: We utilized the high-affinity PPARγ agonist, efatutazone, to activate endogenous PPARγ in a well-defined model for the progression of basal (triple negative) DCIS, MCFDCIS cells, cultured under 2D and 3D conditions. We studied the effects of activated PPARγ on DCIS progression in MCFDCIS xenograft and C3(1)/Tag transgenic mice treated with 30 mg/kg of efatutazone.
RESULTS: In vitro, efatutazone did not alter the MCFDCIS cell proliferation but induced phenotypic and gene expression changes, indicating that activated PPARγ is able to differentiate MCFDCIS cells into more luminal and lactational-like cells. In addition, MCFDCIS tumorsphere formation in 3D was reduced by PPARγ activation. In vivo, efatutazone-treated MCFDCIS tumors exhibited fat deposition along with upregulation of PPARγ responsive genes in both epithelial and stromal compartments, suggesting features of milk-producing mammary epithelial cell differentiation. The efatutazone-treated lesions were less invasive with fewer CD44+/p63+ basal progenitor cells. PPARγ activation downregulated Akt phosphorylation in these tumors, although the ERK pathway remained unchanged. Similar trends in gene expression changes consistent with lactational and luminal cell differentiation were observed in the C3(1)/Tag mouse model after efatutazone treatment.
CONCLUSIONS: Our data suggest that activation of the PPARγ pathway differentiates DCIS lesions and may be a useful approach to delay DCIS progression.

[A Case of Advanced Breast Cancer with Liver Metastasis Successfully Treated with Multi-Disciplinary].
Gan to kagaku ryoho. Cancer & chemotherapy, 45(1):190-192.
We report a case of advanced breast cancer with liver metastasis(T2N1M1, Stage IV)achieving a significant improvement of QOL by multi-disciplinary therapy. The patient was 37-year-old woman who had breast lump and axillary lymph nodes swelling with liver metastasis. A core needle biopsy for breast tumor led to a diagnosis of an invasive ductal carcinoma, negative for estrogen receptor and progesterone receptor, and positive for HER2/neu protein expression. The Ki-67 positive cell index was 40%. She received 16 courses of DOC plus HER plus PER(docetaxel 75mg/m / 2, trastuzumab 6 mg/kg, pertu- zumab 450mg/body, and received 4 courses of EC(epirubicin 90mg/m / 2, cyclophosphamide 600 mg/m2). The breast lesion and liver metastatic lesion disappeared after chemotherapy. We checked up whole body. There was no metastatic lesion. Therefore, we diagnosed a clinical complete response. We performed muscle preserving mastectomy and axillary lymph nodes dissection. The pathological diagnosis from resected specimens were pathological complete response. The surgical margin was negative. She was started the endocrine therapy by tamoxifen(20mg/day). Three years after surgery, she was well without metastases. Multi-disciplinary therapy can improve patient QOL and the clinical outcomes in Stage IV advanced breast cancer.

Polypharmacy and adverse drug events among propensity score matched privately insured persons with and without spinal cord injury.
Spinal cord, 56(6):591-597.
STUDY DESIGN: Retrospective quasi-experimental design.
OBJECTIVES: To compare the incidence of adverse drug events (ADEs) between persons with and without spinal cord injury (SCI), while controlling for all potential and available risk factors.
SETTING: A commercially available claims dataset consisting of ~170 million patient cases in the United States between 2012 and 2013.
METHODS: Participants (aged 18-64 years) included 2779 persons with polypharmacy and traumatic or non-traumatic SCI and 2779 propensity score-matched persons with polypharmacy without SCI. The cohorts were matched using demographic variables including number of concomitant prescriptions, comorbidities, hospital admissions, age, gender, and geographic region. Inpatient and outpatient claims records containing 395 distinct IDC-9 codes indicative of ADEs were extracted. Incidence and frequency of ADEs were compared between groups using logistic and Poisson regression, respectively.
RESULTS: Persons with SCI were significantly more likely to experience an ADE than matched controls (Odds Ratio = 1.45, p < 0.0001). Among persons with ADEs (n = 1552), individuals with SCI experienced fewer ADEs over time than matched controls (Incidence Rate Ratio = 0.91, p < 0.0001).
CONCLUSIONS: While persons with SCI and polypharmacy are at a greater risk for experiencing an ADE, their medical care after an ADE may be better managed than that of a matched control population. There may be a need for practice guidelines that facilitate proactive identification of persons with SCI at the highest risk of ADE. Steps may then be taken to mitigate risk, in contrast to current practice trends that appear to take a reactive approach after an ADE has occurred.

TRPC proteins contribute to development of diabetic retinopathy and regulate glyoxalase 1 activity and methylglyoxal accumulation.
Molecular metabolism, 9:156-167.
OBJECTIVE: Diabetic retinopathy (DR) is induced by an accumulation of reactive metabolites such as ROS, RNS, and RCS species, which were reported to modulate the activity of cation channels of the TRPC family. In this study, we use Trpc1/4/5/6[-/-] compound knockout mice to analyze the contribution of these TRPC proteins to diabetic retinopathy.
METHODS: We used Nanostring- and qPCR-based analysis to determine mRNA levels of TRPC channels in control and diabetic retinae and retinal cell types. Chronic hyperglycemia was induced by Streptozotocin (STZ) treatment. To assess the development of diabetic retinopathy, vasoregression, pericyte loss, and thickness of individual retinal layers were analyzed. Plasma and cellular methylglyoxal (MG) levels, as well as Glyoxalase 1 (GLO1) enzyme activity and protein expression, were measured in WT and Trpc1/4/5/6[-/-] cells or tissues. MG-evoked toxicity in cells of both genotypes was compared by MTT assay.
RESULTS: We find that Trpc1/4/5/6[-/-] mice are protected from hyperglycemia-evoked vasoregression determined by the formation of acellular capillaries and pericyte drop-out. In addition, Trpc1/4/5/6[-/-] mice are resistant to the STZ-induced reduction in retinal layer thickness. The RCS metabolite methylglyoxal, which represents a key mediator for the development of diabetic retinopathy, was significantly reduced in plasma and red blood cells (RBCs) of STZ-treated Trpc1/4/5/6[-/-] mice compared to controls. GLO1 is the major MG detoxifying enzyme, and its activity and protein expression were significantly elevated in Trpc1/4/5/6-deficient cells, which led to significantly increased resistance to MG toxicity. GLO1 activity was also increased in retinal extracts from Trpc1/4/5/6[-/-] mice. The TRPCs investigated here are expressed at different levels in endothelial and glial cells of the retina.
CONCLUSION: The protective phenotype in diabetic retinopathy observed in Trpc1/4/5/6[-/-] mice is suggestive of a predominant action of TRPCs in Müller cells and microglia because of their central position in the retention of a proper homoeostasis of the neurovascular unit.

Salivary duct carcinoma.
Current opinion in otolaryngology & head and neck surgery, 26(2):142-151.
PURPOSE OF REVIEW: The review puts new information on geno- and phenotype of salivary duct carcinoma (SDC) in the perspective of the updated 2017 WHO classification.
RECENT FINDINGS: The proportion of SDC is increasing. This may be because of a true rise in incidence, but certainly to better diagnostic tests and changed WHO definitions. In this light, a substantial proportion of carcinoma expleomorphic adenoma is now attributed to the category of SDC. 'Low-grade SDC' and 'SDC in-situ' of the former WHO classification, are now named low-grade and high-grade intraductal carcinoma (IDC), respectively. Recent series quantify biologic aggressiveness: perineural growth, vascular invasion, and extracapsular extension in lymph node metastasis are each observed in two out of three patients with SDC. Most patients die within 3 years, but once 5-year disease-free survival is reached, further disease activity is exceptional. The typical molecular biological profile with high human epidermal growth factor receptor 2 and androgen receptor expression is increasingly successfully exploited in clinical trials for advanced SDC.
SUMMARY: The aggressive SDC is increasingly diagnosed. Despite intensive combined surgery and radiation therapy, many patients recur, for whom new bullets, targeting the molecular biological mechanisms, are the subject of ongoing clinical trials.

Recent series quantify biologic aggressiveness: perineural growth, vascular invasion, and extracapsular extension in lymph node metastasis are each observed in two out of three patients with SDC. Most patients die within 3 years, but once 5-year disease-free survival is reached, further disease activity is exceptional. The typical molecular biological profile with high human epidermal growth factor receptor 2 and androgen receptor expression is increasingly successfully exploited in clinical trials for advanced SDC.
SUMMARY: The aggressive SDC is increasingly diagnosed. Despite intensive combined surgery and radiation therapy, many patients recur, for whom new bullets, targeting the molecular biological mechanisms, are the subject of ongoing clinical trials.},

[A Case Report of Ipsilateral Nipple Skin Recurrence].
Gan to kagaku ryoho. Cancer & chemotherapy, 44(12):1595-1597.
We report our experience with a patient with breast cancer who showed recurrence in the nipple skin 5 years and 10 months after a breast-preserving surgery. The patient was a woman, and was 65-years old at the time of initial surgery. Breast-preserving surgery and axillary lymph-node dissection were performed for left breast cancer. Invasive ductal carcinoma of the breast(pT3N0M0)was triple-negative, and the patient postoperatively received adjuvant chemotherapy. Left breast pain developed 5 years and 6 months after surgery. Computed tomography showed no evidence of recurrence, and the symptoms resolved after treatment with non-steroidal anti-inflammatory drugs(NSAIDs). After 3 months, however, the left nipple had enlarged to about 1.5 cm, and the surrounding skin was red and painful. Treatment with NSAIDs was thus resumed. After 1 week, redness of the nipple skin and pain were improved. However, the nipple had enlarged to twice its normal size. Nipple skin biopsy was subsequently performed, and revealed adenocarcinoma invading the skin. Left axillary lymph-node metastasis was suspected, but there was no evidence of metastasis to other sites or recurrence. Conservative total mastectomy with axillary lymph-node dissection was thus performed. The histopathological diagnosis was the recurrence of invasive ductal carcinoma, arising mainly in the reticular layer of the dermis. Chemotherapy was administered postoperatively. There has been no evidence of recurrence as of 1 year after surgery.

[A Case of Long-Term Survival of Breast Cancer with Lymph Node and Liver Metastases Treated with Sequential Anti-HER2 Drugs, Chemotherapy, and Endocrine Therapy].
Gan to kagaku ryoho. Cancer & chemotherapy, 44(12):1838-1840.
A 50s-year-old woman underwent left partial mastectomy with axillary lymphadenectomy for breast cancer. Histological examination indicated invasive ductal carcinoma, pT1c, pN0, Stage I , ly(+), ER(+), PgR(+). She received adjuvant therapy with tamoxifen and 50 Gy of irradiation to the residual breast. Four years after mastectomy, she was found to have left Rotter lymph node metastasis; then, anastrozole was administered instead of tamoxifen. Nine months later, she was found to have liver metastasis. Immunohistostaining revealed that the breast cancer was HER2-positive; she received AC followed by paclitaxel(PTX)with trastuzumab(T), and achieved complete response(CR). Subsequently, abdominal, cervical lymph node, and liver metastases appeared. Letrozole followed by lapatinib with capecitabine, FEC100, PTX with T, eribulin, S-1, docetaxel with pertuzumab and T, everolimus with exemestane, bevacizumab, and PTX were then administered, resulting in long-term disease control. Sixteen years after mastectomy, she receives outpatient chemotherapy in performance status 1 state.

[A Case of Bladder Metastasis from Breast Cancer].
Gan to kagaku ryoho. Cancer & chemotherapy, 44(12):1933-1935.
A 64-year-old woman visited hospital with a chief complaint of a nodule at the left neck skin. Skin biopsy revealed adenocarcinoma, and the diagnosis was skin metastasis of unknown primary origin. Positron emission tomography and computed tomography showed multiple bone and lymph node metastasis, left breast tumor, bladder tumor, and hydronephrosis. A needle biopsy of breast revealed invasive ductal carcinoma, and transurethral biopsy of bladder revealed adenocarcinoma. The findings were similar to those for the breast and the expression pattern of estrogen-receptor was the same. We diagnosed her with breast cancer and bladder metastasis. We administered systemic chemotherapy, however she died 10 days later. Bladder metastasis of breast cancer is rarely encountered in clinical practice and is often accompanied by life threatening symptoms. Careful histopathological examinations and rapid systemic chemotherapy are significant.

Expression Analysis of miR-29b in Malignant and Benign Breast Tumors: A Promising Prognostic Biomarker for Invasive Ductal Carcinoma With a Possible Histotype-Related Expression Status.
Clinical breast cancer, 18(4):305-312.e3.
BACKGROUND: Aberrations in microRNA levels seem to provide valuable information regarding breast cancer prognosis and therapy. In this study, we sought to analyze miR-29b expression in breast tumors and thus explore its clinical value.
MATERIALS AND METHODS: One hundred twenty-one malignant and 56 benign breast tissue specimens were collected and subjected to extraction of total RNA, which was polyadenylated and reverse transcribed to cDNA. Subsequently, a highly sensitive quantitative real-time polymerase chain reaction protocol was developed and miR-29b levels, estimated via the comparative CT method, were finally subjected to comprehensive statistical analysis.
RESULTS: MiR-29b levels did not differ between the analyzed benign and malignant breast tissue specimens, but were found to be significantly (P = .010) decreased in invasive ductal adenocarcinomas compared with their lobular counterparts, albeit receiver operating characteristics curve analysis did not verify the latter correlation. Additionally, miR-29b expression was elevated in samples with positive estrogen receptor status (P = .021) in the overall population, whereas it was negatively correlated (P = .035) with primary tumor staging in the ductal subset and increased in poorly-differentiated tumors of lobular origin (P = .041). Furthermore, Kaplan-Meier and Cox regression analyses showed that patients with ductal carcinoma and elevated miR-29b levels had a significantly longer disease-free survival (P = .010) and a lower risk to relapse (hazard ratio = 0.35, 95% confidence interval, 0.15-0.81; P = .014).
CONCLUSION: Our results provide evidence that miR-29b levels constitute a promising biomarker of favorable prognosis for patients with invasive ductal breast carcinoma and imply that its expression status might be affected by the histological origin of breast malignancy.

Breast carcinoma in sclerosing adenosis: a clinicopathological and immunophenotypical analysis on 206 lesions.
Journal of clinical pathology, 71(6):546-553.
AIMS: To fully elucidate the clinicopathological features of breast carcinoma in sclerosing adenosis (SA-BC).
METHODS: Clinical and histological characteristics of 206 SA-BCs from 180 patients were retrospectively evaluated. Immunohistochemical phenotype was examined. The clinicopathological relevance of the topographical pattern of SA-BCs was analysed.
RESULTS: Overall, up to 46 patients (25.6%) had contralateral cancer, either SA associated or not. Of 99 cases who underwent core needle biopsy (CNB), 36 were underestimated as adenosis or atypical ductal hyperplasia at CNB, 5 invasive cases were misinterpreted as in situ carcinomas, whereas 4 ductal carcinoma in situ (DCIS) cases were overdiagnosed as invasive carcinoma. Microscopically, 163 tumours were in situ, including 136 DCIS, 19 lobular carcinomas in situ (LCIS) and 8 mixed DCIS/LCIS; of these carcinomas in situ (CIS), 37 had microinvasion. The DCIS group exhibited low, intermediate and high grades in 53.7%, 34.6% and 11.8% of cases, respectively, mostly with solid (43.4%) or cribriform (41.9%) pattern. Forty out of 43 invasive cases were invasive ductal carcinoma (IDC), mostly DCIS predominant. Immunophenotypically, luminal A phenotype was identified in 55.1%, 63.2% and 45.0% of DCIS, LCIS and IDC cases, respectively. Topographical type A group (carcinoma being entirely confined to SA, n=176) was characterised by smaller size, less invasiveness, lower grade and more frequency of luminal A immunophenotype compared with type B group (≥ 50% but not all of the carcinomatous lesion being located in SA, n=30) (all P<0.05).
CONCLUSIONS: CIS, especially non-high-grade DCIS, represents the most common variant of SA-BC, and luminal A is the most predominant immunophenotype. CNB assessment might be challenging in some SA-BCs. The topographical pattern has great clinicopathological relevance. Careful evaluation of the contralateral breast and long-term follow-up for patients with SA-BC is necessary given its high prevalence of bilaterality.

RJR Experience and Expertise
Researcher
Robbins holds BS, MS, and PhD degrees in the life sciences. He served as a tenured faculty member in the Zoology and Biological Science departments at Michigan State University. He is currently exploring the intersection between genomics, microbial ecology, and biodiversity — an area that promises to transform our understanding of the biosphere.
Educator
Robbins has extensive experience in college-level education: At MSU he taught introductory biology, genetics, and population genetics. At JHU, he was an instructor for a special course on biological database design. At FHCRC, he team-taught a graduate-level course on the history of genetics. At Bellevue College he taught medical informatics.
Administrator
Robbins has been involved in science administration at both the federal and the institutional levels. At NSF he was a program officer for database activities in the life sciences, at DOE he was a program officer for information infrastructure in the human genome project. At the Fred Hutchinson Cancer Research Center, he served as a vice president for fifteen years.
Technologist
Robbins has been involved with information technology since writing his first Fortran program as a college student. At NSF he was the first program officer for database activities in the life sciences. At JHU he held an appointment in the CS department and served as director of the informatics core for the Genome Data Base. At the FHCRC he was VP for Information Technology.
Publisher
While still at Michigan State, Robbins started his first publishing venture, founding a small company that addressed the short-run publishing needs of instructors in very large undergraduate classes. For more than 20 years, Robbins has been operating The Electronic Scholarly Publishing Project, a web site dedicated to the digital publishing of critical works in science, especially classical genetics.
Speaker
Robbins is well-known for his speaking abilities and is often called upon to provide keynote or plenary addresses at international meetings. For example, in July, 2012, he gave a well-received keynote address at the Global Biodiversity Informatics Congress, sponsored by GBIF and held in Copenhagen. The slides from that talk can be seen HERE.
Facilitator
Robbins is a skilled meeting facilitator. He prefers a participatory approach, with part of the meeting involving dynamic breakout groups, created by the participants in real time: (1) individuals propose breakout groups; (2) everyone signs up for one (or more) groups; (3) the groups with the most interested parties then meet, with reports from each group presented and discussed in a subsequent plenary session.
Designer
Robbins has been engaged with photography and design since the 1960s, when he worked for a professional photography laboratory. He now prefers digital photography and tools for their precision and reproducibility. He designed his first web site more than 20 years ago and he personally designed and implemented this web site. He engages in graphic design as a hobby.
