Investigating The Role Of Endothelial Breast Cancer Susceptibility Gene 2 In Doxorubicin-Induced Cardiotoxicity, Berk U. Rasheed
Electronic Thesis and Dissertation Repository
Doxorubicin (Dox) is a chemotherapeutic drug used to treat various malignancies including breast and ovarian cancers. Accumulating evidence implicates cardiac impairments associated with Dox treatment. The Breast Cancer Susceptibility Gene 2 (BRCA2) functions to maintain genome-wide stability by promoting DNA-damage repair. Accordingly, cardiomyocyte damage is specifically regulated by contributors of DNA damage repair such as BRCA2. The endothelium, the innermost cells of every blood vessel, act to protect our tissues from noxious elements, however, recent evidence suggests that BRCA2 knockdown compromises endothelial cell function. A putative role of endothelial BRCA2 during Dox-induced cardiotoxicity (DIC) remains unknown. We hypothesized that endothelial-specific …
