Pro-apoptotic effects of tectorigenin on human hepatocellular carcinoma HepG2 cells

Figure 10 Caspase activities in tectorigenin-treated HepG2 cells. Cells were treated with tectorigenin at the indicated concentrations for 24 and 48 h. Cytosolic extracts were prepared and assayed for caspase activities as described in “Materials and Methods”. A: Alteration of caspase-3 activity in tectorigenin-induced HepG2 cells for indicated time; B: Effect of tectorigein on caspase-8 activity in HepG2 cells; C: Changes of caspase-9 activity in tectorigenin-treated HepG2 cells at 5, 10 and 20 mg/L for 24 and 48 h. Data are expressed as the mean of three individual experiments ± SD. Difference was considered statistically significant when ^aP < 0.05 and ^bP < 0.01 vs control.
