BRCA1 and atherosclerosis: In order to get an insight about the cause and/or effect relationship of BRCA2 with atherosclerosis in ECs, we next measured BRCA2 expression levels in ECs treated with different doses (0, 5, 10, 20, 50, and 100 μg/ml) of oxLDL for 24 hr and measured BRCA1 and BRCA2 expression.
