Breast cancer risk is significantly elevated for women who carry germ-line mutations in the tumor suppressor gene BRCA1. While breast tissue is composed of multiple cell types and all of them inherit the same BRCA1 mutation in mutation-carrying women, BRCA1-associated breast cancer specifically originates from a cell type called luminal progenitor cells. BRCA1 plays a critical role in repair of damaged DNA, which is universally important for all proliferating cells in the body. Thus, it remains a puzzle as to why breast luminal cells in BRCA1 mutation carriers are most susceptible to tumor development. We recently uncovered an antagonizing relationship between BRCA1 and a dedicated transc...
