Each histogram represents the mean ± S.D. of caspase activity obtained from four independent experiments and p-values were denoted as ‘*’ and ‘**’ indicating the level of significance over untreated control or zero time point. A: histogram for caspase-9/caspase-6 activity in K562 cells treated with various concentrations of benzamide; B: dose dependent increase of caspase-3 activity in K562 cells treated with different doses of benzamide; C: Caspase-3 activity in K562 cells treated with 5 mM benzamide for different time of interval.
