DECPR induced caspase-3 and −9 activation in HT-29 cells. Cells were treated with different concentrations of DECPR for 24 h, in the presence or absence of specific inhibitors, following with a fluorometric analysis of caspases activities. Treated cells without inhibitors showed the significant activation for caspase-3 and −9 at 6.25 to 50 μg/mL concentrations, while there was no significant fold-change in caspase-8 activity. The data represent the means ± SEM of three independent experiments. *P < 0.05 compared with the untreated group.
