Differential effects of JS-K on cell death, apoptosis and PP2A activation in five HHC cells and L02 cells.a Dose-dependent effects of JS-K on cell death in the five HCC cells and L02 cells. The cells were exposed to JS-K at the indicated concentrations for 24, 48, 72 h. b Dose-dependent effects of JS-K on cell apoptosis in the five HCC cells and L02 cells. c-d Effects of JS-K on the expression of PP2A. The cells were treated with JS-K at the indicated concentration for 24 h. Cell lysates were prepared and assayed for PP2A by Western blotting. Data are mean ± SD. n = 3 for each concentration. *P < 0.05,**P < 0.01, vs. control group
