Effects of auransterol on caspase activity in HT-29 colon cancer cells. (A) Effects of auransterol (0–50 μM) on activity of caspase 3 and 7 after 24 h of treatment. (B) Protein expression of procaspase-3 and (C) procaspase-7. Paclitaxel was used as positive control (0.01 μM). Data are expressed as the means ± SEM (n = 3) and analyzed by one-way ANOVA using Dunnett’s multiple-comparison test (**P < 0.01, ***P < 0.01) of three independent assays.
