Breast cancer is a public health problem in the Western countries. Several studies have shown that BRCA2, like BRCA1 oncosuppressors, are strongly involved in hereditary and sporadic mammary carcinogenesis. It has also been suggested that soy has a protective effect against breast cancer in Asia and, more particularly, phytoestrogens such as daidzein and genistein. Thus, phytoestrogens may have...
Single Nucleotide Polymorphisms (SNPs) in genes involved in the DNA Base Excision Repair (BER) pathway could be associated with cancer risk in carriers of mutations in the high-penetrance susceptibility genes BRCA1 and BRCA2, given the relation of synthetic lethality that exists between one of the components of the BER pathway, PARP1 (poly ADP ribose polymerase), and both BRCA1 and BRCA2. In th...
The aim of this study was to estimate the contribution of deleterious mutations in BRCA1, BRCA2, MLH1, MSH2, MSH6 and PMS2 to invasive epithelial ovarian cancer (EOC) in the population. The coding sequence and splice site boundaries of all six genes were amplified in germline DNA from 2240 invasive EOC cases and 1535 controls. Barcoded fragment libraries were sequenced using the Illumina GAII o...
PURPOSE Several epidemiologic studies have reported that carriers of germline mutations in the BRCA2 gene have an increased risk of prostate cancer, with the highest risk observed in men diagnosed at earlier ages. However, studies of the contribution of BRCA2 mutations to the etiology of hereditary prostate cancer (HPC) have been inconsistent. EXPERIMENTAL DESIGN To further address this issue...
Mutation in homologous recombination repair (HRR) pathway is well established ovarian cancers. Multiple trials have shown variable efficacy prostate Mutations other than BRCA1/BRCA2 been recently reported We describe a unique case of an elderly male with metastatic castration-resistant cancer. He responded to hormonal therapy for 6 months but later progressed. Chemotherapy docetaxel produced se...
The majority of hereditary breast and ovarian cancers can be accounted for by germline mutations in the BRCA1 and BRCA2 genes. Genetic counselling and testing in high-risk patients in the Czech Republic began in 1997 in two centres (Masaryk Memorial Cancer Institute in Brno, MMCI, and the General University Hospital plus the First Faculty of Medicine, Charles University in Prague, 1FMUK). Healt...
Breast cancer (BC) is the most common cancer of women all over the world. BRCA1 and BRCA2 gene mutations comprise the most important genetic susceptibility of BC. Except for few common mutations, the spectrum of BRCA1 and BRCA2 mutations is heterogeneous in diverse populations. 185AGdel and 5382insC are the most important BRCA1 and BRCA2 alterations which have been encountered in most of the po...
Homologous recombination (HR) is critical for maintaining genome stability through precise repair of DNA double-strand breaks (DSBs) and restarting stalled or collapsed DNA replication forks. HR is regulated by many proteins through distinct mechanisms. Some proteins have direct enzymatic roles in HR reactions, while others act as accessory factors that regulate HR enzymatic activity or coordin...
Mutations in the breast cancer susceptibility gene 2 (BRCA2) are commonly found in familial pancreatic cancer. Recently, EMSY (11q13.5) has been described as a BRCA2 interacting protein capable of binding and inactivating the protein domain encoded by exon 3 of the BRCA2 gene. Amplification of EMSY occurs in 13% of sporadic breast cancers and is directly linked to increased expression. Here we ...
Since the discovery of the tumour suppressor BRCA2 (encoded by breast-cancer susceptibility gene 2), cells lacking the fully functional protein have consistently been found to show increased sensitivity to a variety of DNA-damaging agents, particularly those that cross-link DNA. In this short review, we will bring together these findings and discuss them in the light of our recent in vivo data ...
