Carriers of mutations in the BRCA2 gene have a high risk of developing breast and other cancers. The BRCA2 gene, which is located on human chromosome 13, encodes a very large protein of only poorly understood function. To define regions of sequence conservation and highlight potentially functionally important domains, we have cloned and characterized the chicken BRCA2 gene, the first non-mammal...

PURPOSE High-grade serous carcinoma (HGSC) accounts for the majority of epithelial ovarian cancer deaths. Genomic and functional data suggest that approximately half of unselected HGSC have disruption of the BRCA pathway and defects in homologous recombination repair (HRR). Pathway disruption is regarded as imparting a BRCAness phenotype. We explored the molecular changes in HGSC arising in ass...

The recent completion of the draft human genome sequence (1) presents countless opportunities to investigate genome function and the importance of alterations in the genetic code in both health and disease. Among the most rapidly adopted of the emerging genomic technologies, microarray hybridization permits the parallel determination of the expression of tens of thousands of genes in tissue sam...

BACKGROUND Germ-line mutations of the BRCA2 gene are the highest known risk factors for male breast cancer (MBC). Mutations in BRCA2 are mainly point mutations in contrast to BRCA1 in which large genomic rearrangements are quite common. In recent literature, however, genomic alterations of BRCA2 have been linked especially to male breast cancer families. We wanted to screen large genomic deleti...

background: germ-line mutations of brca1 and brca2 genes are responsible for approximately 25-30% of dominantly inherited familial breast cancers; still a big part of genetic component is unknown. the aim of this study was to investigate genetic causes of familial breast cancer in a pedigree with recessive pattern of inheritance. methods: we applied exome sequencing as a useful approach in hete...

objective: in an attempt to develop safer and more effective gene therapy approaches as a realistic treatment for various forms of cancer, researchers are increasingly using tumor-specific promoters (tsp) to drive the expression of the gene of interest and eradicate cancer cells. in this study, for the first time we introduce the oct-4 promoter as a cancer-specific promoter with a high efficacy...

BACKGROUND Breast cancer is the most common cancer in women worldwide. About 5 to 10% of cases are due to an inherited predisposition in two major genes, BRCA1 and BRCA2, transmitted as an autosomal dominant form. Male breast cancer is rare and is mainly due to BRCA2 than BRCA1 germline mutations. OBJECTIVE Molecular study of BRCA2 gene in man with familial breast cancer. METHODS PCR and di...
