Effect of DK1913 on the activation of mitochondria-mediated caspase cascade in HCT116 cells. HCT116 cells were treated with 10 μM DK1913 for 24 h. Cell lysates were subjected to immunoblotting using antibodies against caspase-9, cleaved caspase-7, caspase-3, and PARP. Arrows: proform; arrowhead: cleaved form; GAPDH: internal control. Band intensities of each blot were measured using ImageJ software and expressed relative to the basal band intensity (set to 1) after adjusting to GAPDH levels. The data are expressed as means ± SD (n = 3). NS, not significant; ; ; ; compared with the 0-time control according to Dunnett’s multiple comparisons test.
