Abstract:
Objective To determine the effect of caspase 9 in the apoptosis of hepatoma cells induced by flurouracil , and to investigate the activity alteration and proteolytic cleavage of caspase 9. Methods The human hepatoma HepG2 cells were treated with flurouracil for 2,4,8,16,24h respectively. The caspase 9 activity was detected using caspase 9 Fluorescent Assay Kit.Proteolytic cleavage of caspase 9 was analyzed by Western blot.The apoptotic rates of HepG2 cells induced by flurouracil with or without caspase 9 inhibitor treatment were measured by flow cytometry. Results Four hours after being treated with flurouracil, the caspase 9 activity in HepG2 cells increased gradually and reached the peak at 16h.Compared with the control group, the difference was significant (P
