Simvastatin induces apoptosis in human breast cancer cells: p53 and estrogen receptor independent pathway requiring signalling through JNK

The effect of simvastatin, a widely used statin for the treatment of hypercholesterolemia, was investigated in the estrogen receptor (ER)-positive MCF-7, and the ER-negative MDA-MB 231 human breast cancer cell lines. Simvastatin induced cell cycle arrest and apoptosis in both cells. These effects of simvastatin were not altered by 17-beta-estradiol treatment
