Figure 4From: Upregulation of death receptor 5 and activation of caspase 8/3 play a critical role in ergosterol peroxide induced apoptosis in DU 145 prostate cancer cellsEffect of caspase 8 inhibitor Z-IETD-FMK on PARP in EP treated DU 145 prostate cancer cells. DU 145 cells were treated with EP (25 or 50 μM) and/or caspase 8 inhibitor Z-IETD-FMK. Western blot assay (a) and FACS analysis (b) were performed.Back to article page
