Generic caspase-based apoptosis of CPC-treated oral cancer Ca9-22 cells and the effect of NAC pretreatment. a With or without 2 mM NAC pretreatment for 1 h, Ca9-22 cells treated with 0, 3, 6, 9, and 12 μM of CPC for 24 h were stained with 1 μl 500X TF2-VAD-FMK. The right side indicates the pancaspase (Pan) positive region in each panel. b Quantificative analysis of pan-caspase fluorescent intensity. Data, mean ± SD (n = 3). For the same drug treatment of different concentrations, data marks (a to e) without overlapping by the same lower-case letter significantly differed (one-way ANOVA with Tukey HSD Post Hoc Test)
