Researchers uncover mechanisms of estrogen in promoting cell death in breast cancer

... membrane of cell organelles called mitochondria. Estradiol increased the expression of several proteins on the membrane of cell mitochondria, led to depolarization of the mitochondrial membrane, and stimulated the release of a molecule called cytochrome c into the cell's interior, where it could activate several ...
