Abstract
The relationship between erythrocyte membrane n-3 PUFA and breast cancer risk is controversial. We aimed to examine the associations of erythrocyte membrane n-3 PUFA with odds of breast cancer among Chinese women by using a relatively large sample size. A case-control study was conducted including 853 newly diagnosed, histologically confirmed breast cancer cases and 892 frequency-matched controls (5-year interval). Erythrocyte membrane n-3 PUFA were measured by GC. Logistic regression and restricted cubic spline were used to quantify the association between erythrocyte membrane n-3 PUFA and odds of breast cancer. Erythrocyte membrane α-linolenic acid (ALA), docosapentaenoic acid (DPA) and total n-3 PUFA were inversely and non-linearly associated with odds of breast cancer. The OR values (95 % CI), comparing the highest with the lowest quartile (Q), were 0·57 (0·43, 0·76), 0·43 (0·32, 0·58) and 0·36 (0·27, 0·49) for ALA, DPA and total n-3 PUFA, respectively. Erythrocyte membrane EPA and DHA were linearly and inversely associated with odds of breast cancer ((EPA: ORQ4 v. Q1 (95 % CI) = 0·59 (0·45, 0·79); DHA: ORQ4 v. Q1 (95 % CI) = 0·50 (0·37, 0·67)). The inverse associations were observed between ALA and odds of breast cancer in postmenopausal women, and between DHA and oestrogen receptor+ breast cancer. This study showed that erythrocyte membrane total and individual n-3 PUFA were inversely associated with odds of breast cancer. Other factors, such as menopause and hormone receptor status, may warrant further investigation when examining the association between n-3 PUFA and odds of breast cancer.

Abstract
Triple-negative breast cancer (TNBC) is a special subtype of breast cancer that is difficult to treat. It is crucial to identify breast cancer-related genes that could provide new biomarkers for breast cancer diagnosis and potential treatment goals. In the development of our new high-risk breast cancer prediction model, seven raw gene expression datasets from the NCBI gene expression omnibus (GEO) database (GSE31519, GSE9574, GSE20194, GSE20271, GSE32646, GSE45255, and GSE15852) were used. Using the maximum relevance minimum redundancy (mRMR) method, we selected significant genes. Then, we mapped transcripts of the genes on the protein-protein interaction (PPI) network from the Search Tool for the Retrieval of Interacting Genes (STRING) database, as well as traced the shortest path between each pair of proteins. Genes with higher betweenness values were selected from the shortest path proteins. In order to ensure validity and precision, a permutation test was performed. We randomly selected 248 proteins from the PPI network for shortest path tracing and repeated the procedure 100 times. We also removed genes that appeared more frequently in randomized results. As a result, 54 genes were selected as potential TNBC-related genes. Using 14 out the 54 genes, which are potential TNBC associated genes, as input features into a support vector machine (SVM), a novel model was trained to predict high-risk breast cancer. The prediction accuracy of normal tissues and TNBC tissues reached 95.394%, and the predictions of Stage II and Stage III TNBC reached 86.598%, indicating that such genes play important roles in distinguishing breast cancers, and that the method could be promising in practical use. According to reports, some of the 54 genes we identified from the PPI network are associated with breast cancer in the literature. Several other genes have not yet been reported but have functional resemblance with known cancer genes. These may be novel breast cancer-related genes and need further experimental validation. Gene ontology (GO) enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were performed to appraise the 54 genes. It was indicated that cellular response to organic cyclic compounds has an influence in breast cancer, and most genes may be related with viral carcinogenesis.

Abstract
Background:
In view of the estrogenic receptor inhibitory properties of coumarin
nucleus, long chain nature of fatty acid and anti-breast cancer activity of fatty acids, it was proposed
to attach long chain fatty acids at 3rd,4th and 7th position of coumarin nucleus and evaluate for their
anti-breast cancer activity through suitable in-vitro methods.
Methods:
The present study focuses a library of fatty acid coumarin conjugates as ligands to the
ligand-binding domain of the human estrogen receptor α (PDB ID 2IOG) and their binding affinities
using GLIDE module of Schrodinger after ascertaining their drug-likeness with QIKPROP. The
compounds LNAC 8, SAC 1 and OAC 5 are the best hits based on their docking scores as well as
the Prime MM-GBSA free energy of binding. Based on the in-silico results and synthetic feasibility
the compounds SAC 1 PAC 1 and OAC 1 are synthesized, characterized and investigated for their
time interval growth inhibitory effect on MCF-7 which is an ER positive breast cancer cell lines.
Results:
SAC 1, showed better in vitro growth inhibitory effect in sub micromolar range as
compared to Tamoxifen, a standard estrogen receptor modulator.
Conclusion:
Conclusively, in silico molecular docking studies have been very useful in predicting
the pharmacokinetic profiles and the binding affinities of new hits before a detailed preclinical and
clinical evaluation.

Abstract
Aim: To understand the importance of homologous recombination repair pathway in development of breast carcinoma (BC), alterations of some key regulatory genes like BRCA1, BRCA2, FANCC and FANCD2 were analyzed in pretherapeutic/neoadjuvant chemotherapy (NACT)-treated BC samples. Materials & methods: Alterations (deletion/methylation/expression) of the genes were analyzed in 118 pretherapeutic and 41 NACT-treated BC samples. Results: High deletion/methylation (29–68%) and 64–78% overall alterations of the genes were found in the samples. Concordance was evident between alteration and protein expression of the genes. Estrogen/progesterone receptor-negative tumors showed significantly high alterations even in NACT-treated samples having low CD44 and proliferating cell nuclear antigen expression. Pretherapeutic patients with alterations showed poor prognosis. Conclusion: Alterations of homologous recombination repair pathway genes are needed for the development of BC.

Abstract
Omega-3 fatty acids (FA) are polyunsaturated essential FA with anti-inflammatory properties. The most potent are the marine-derived eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which counteract the pro-inflammatory omega-6 FA. Americans take in an average of only 100 mg of EPA plus DHA per day resulting in a low omega-3:omega-6 intake ratio of 1:10 favoring inflammation. Cohort and/or case control studies suggest EPA and DHA are promising for breast, colon, and prostate cancer risk reduction. Mechanistic studies largely in preclinical models suggest EPA and DHA reduce synthesis of prostaglandin E2 and other inflammatory cytokines, decrease aromatase activity and proliferation, promote differentiation and apoptosis, and enhance insulin sensitivity. Animal models using 7% to 20% omega-3 added to chow are promising; however, this amount of omega-3 in a diet is unlikely to be acceptable to humans. The optimal EPA:DHA ratio or the lowest effective dose of EPA and DHA for cancer prevention is unclear, but it is likely to be more than 600 mg/day, which is six times the average American intake. Most phase II prevention trials use 1 to 3.3 g of EPA and DHA, which is safe and well tolerated. Two grams of EPA was associated with fewer polyps in individuals with familial adenomatous polyposis in a randomized, placebo-controlled trial. Identification of serum risk biomarkers modulated by EPA and DHA in healthy humans has remained elusive, but phase II prevention trials with tissue obtained for risk and response biomarkers are ongoing.

Abstract
The aim of the study is to understand the importance of the Wnt/β-catenin pathway in the development of breast cancer (BC) and its association with different clinicopathological parameters. Alterations (deletion/methylation/expression) of some Wnt/β-catenin pathway antagonists like APC, SFRP1/2, CDH1 and activator β-catenin (CTNNB1) were analyzed in primary BC in Indian patients. High frequencies (65-70%) of overall alterations (deletion/methylation) of the antagonists were seen in the BC samples. Also, 99% (156/158) of the samples showed alterations in any one of the genes, indicating the importance of this pathway in the development of this tumor. Co-alterations of these genes were observed in 30% of samples, with significantly high alterations in late-onset (37%) and estrogen receptor (ER)-/progesterone receptor (PR)- (37%) BC compared with early onset (21%) and ER/PR+ (18%) BC samples, respectively. Significantly high (P-value = 0.001-0.02) alterations of APC and CDH1 genes were seen in ER-/PR- BC compared with ER/PR+ BC. Immunohistochemical analysis showed reduced expression of the Wnt antagonists in BC concordant with their molecular alterations. Nuclear localization of β-catenin showed significant association with alterations in the antagonists and was also significantly high in the ER-/PR- BC samples. Alterations of SFRP2 coupled with a late clinical stage and low/nulliparity predicted the worst prognosis in BC patients. Therefore, the present study suggests that cumulative alterations in more than one Wnt antagonist along with increased nuclear accumulation of β-catenin play an important role in the development of BC and have significant clinical as well as prognostic importance.

Abstract
Insights from vitamin D-resistant New World primates and their human homologues as models of natural and pathological insensitivity to sterol/steroid action have uncovered a family of novel intracellular vitamin D and estrogen regulatory proteins involved in hormone action. The proteins, known as "vitamin D or estrogen response element-binding proteins", behave as potent cis-acting, transdominant regulators to inhibit steroid receptor binding to DNA response elements and is responsible for vitamin D and estrogen resistances. This set of interactors belongs to the heterogeneous nuclear ribonucleoprotein (hnRNP) family of previously known pre-mRNA-interacting proteins. This review provides new insights into the mechanism by which these novel regulators of signaling and metabolism can act to regulate responses to vitamin D and estrogen. In addition the review also describes other molecules that are known to influence nuclear receptor signaling through interaction with hormone response elements.
