Figure 7. The cell apoptosis could be enhanced by the combination of cisplatin and sh-TRPM2-AS in OvC cells. (A) Cisplatin at corresponding IC50 concentrations inhibited 50% cell viability in CAOV3 and SKOV3 cells transfected with sh-TRPM2-AS. NC, negative control. (B) The combination of cisplatin and sh-TRPM2-AS significantly enhanced cell apoptosis in CAOV3 and SKOV3 cells. Blank, blank control. NC, negative control. **P<0.001 compared with blank control; ##P<0.001, compared with NC+cisplatin. (C) The OvC cells treated with cisplatin at corresponding IC50 concentrations and the transfection of sh-TRPM2-AS inhibited the protein expression of p27 and BCL-2, and promoted the protein expression of Bax. p27, BCL-2 and Bax were the cell apoptosis-associated proteins. NC, negative control. *P<0.05, **P<0.001 compared with negative control.
