Sulforaphane increased anti-apoptotic protein expression in p53-WT cells, but not in p53-KO cells. HCT116 cells were treated with sulforaphane for 8 h. The protein levels of Bcl-2 and Bax were analyzed by western blotting. Values represent mean ± SEM (N = 5). Bars not sharing same alphabetical letter represent statistically significant differences among groups (p < 0.05). NS, not significant
