Endothelial Cell-Specific Loss Of Breast Cancer Susceptibility Gene 2 Exacerbates Atherosclerosis, David C.R. Michels
Electronic Thesis and Dissertation Repository
Despite mounting concern over the increased risk of cardiovascular disease in breast cancer patients, studies evaluating the common genetic/molecular link between these diseases are limited. Mutations in the breast cancer susceptibility genes (BRCA1&2) predispose carriers to breast and ovarian cancers due to compromised DNA damage repair capacity leading to DNA damage accumulation; in cancer cells, and in other cell-types including endothelial cells, causing atherosclerotic hallmarks of endothelial dysfunction/apoptosis. We present a new understanding of BRCA2’s protective functionality in the setting of atherosclerosis. Studies have thus far demonstrated that while loss of endothelial BRCA2 in mice does not affect a molecular …
