Activation of caspase 3/7 in breast and prostate cancer cells by SC/D-F9. MCF-7 and MDA-MB-231 cells were treated with DMSO (0.1%) or SC/D-F9 (8.5 or 10.0 μg/ml, repectively) for 24 hr while the PC-3 and DU-145 cells were treated with DMSO (0.1%) or SC/D-F9 (7.4 and 7.2 μg/ml, respectively) for 48 hr. The cells were reacted with the green fluorescent-labeled caspase inhibitor, FAM-VAD-FMK, and observed under a fluorescent microscope.
