Verapamil-induced caspase expression in MCF7 and MDA-MB-231. Representative caspase immunoblots of MDA-MB-231 and MCF7 cells under different concentrations (0, 10, and 20 μM) of verapamil. a Caspase-3 expressed in MDA-MB-231 but not in MCF7 cells. b Verapamil concentration-dependent expression levels of caspase-3 in MDA-MB-231. c Caspase-9 expression in MCF7 cells. d Verapamil concentration-dependent expression levels of caspase-9 in MCF7. Alpha-actin was used as a loading control. Asterisk indicates statistical significance
