FIG. 6.

Apoptosis of T24 cells after treatment of p38 inhibitor SB203580 and compound K. (A) Cell growth rates of compound K treatment, SB203580 treatment, compound K with SB203580 treatment, and control were measured by CCK-8 assays and the data expressed as a mean percentage compared with that of control from four independent experiments. **p<0.01 versus control group; ^##p<0.05 versus CK group. The treatment time for all the cell groups was 24 hours. (B) The expression of cleaved procaspase 3, procaspase 9, and cytochrome c in the cytosol of T24 cells treated with p38 inhibitor SB203580 and compound K were analyzed by western blot. Representative data from three independent experiments are shown.
