BRCA1, PARP, and 53BP1: conditional synthetic lethality and synthetic viability.
BRCA1 plays a critical role in the regulation of homologous recombination (HR)-mediated DNA double-strand break repair. BRCA1-deficient cancers have evolved to tolerate loss of BRCA1 function. This renders them vulnerable to agents, such as PARP inhibitors, that are conditionally 'synthetic lethal' with their underlying repair defect. Recent studies demonstrate that BRCA1-deficient cells may ac...
متن کاملThe p53 mutational spectrum associated with BRCA1 mutant ovarian cancer.
PURPOSE Cancer-specific p53 mutational spectra have been identified. Data from murine models and human BRCA1-related hereditary breast cancers suggest that both unique and specific BRCA1-associated p53 mutations may be found in BRCA1-related ovarian cancers. EXPERIMENTAL DESIGN The p53 mutational spectrum from ovarian cancers containing either somatic or germ-line BRCA1 mutations was compared...
متن کاملA high-throughput functional complementation assay for classification of BRCA1 missense variants.
UNLABELLED Mutations in BRCA1 and BRCA2 account for the majority of hereditary breast and ovarian cancers, and therefore sequence analysis of both genes is routinely conducted in patients with early-onset breast cancer. Besides mutations that clearly abolish protein function or are known to increase cancer risk, a large number of sequence variants of uncertain significance (VUS) have been ident...
متن کاملBRCA1 Induces Major Energetic Metabolism Reprogramming in Breast Cancer Cells
The hypermetabolic nature of cancer cells and their increased reliance on "aerobic glycolysis", as originally described by Otto Warburg and colleagues, are considered metabolic hallmarks of cancer cells. BRCA1 is a major tumor suppressor in breast cancer and it was implicated in numerous pathways resulting in anticarcinogenic functions. The objective of our study was to address specific contrib...
متن کاملBRCA1 induces antioxidant gene expression and resistance to oxidative stress.
Mutations of the breast cancer susceptibility gene 1 (BRCA1), a tumor suppressor, confer an increased risk for breast, ovarian, and prostate cancers. To investigate the function of the BRCA1 gene, we performed DNA microarray and confirmatory reverse transcription-PCR analyses to identify BRCA1-regulated gene expression changes. We found that BRCA1 up-regulates the expression of multiple genes i...
