Mechanism of PX-12 induced apoptosis of hepatocellular carcinoma cells through oxidative stress
AIM:To explore the mechanism of PX-12 induced apoptosis of hepatocellular carcinoma cells.METHODS:Human hepatoma cell line Huh7 was se-lected as the main research object.After the cells were treated with thioredoxin inhibitor PX-12,the cell viability was detected by CCK8 method,the cell mi-gration ability was detected by cell scratch test,the cell proliferation ability was detected by cell prolif-eration kit,the levels of intracellular reactive oxygen species and apoptosis were detected by flow cy-tometry,and the expression of apoptosis-related proteins were detected by Western blot.RESULTS:Compared with the control group,the cell viability,migration ability and proliferation ability of PX-12 treatment group were significantly decreased(P＜0.05),and the level of intracellular reactive oxygen species was increased(P＜0.05)in a concentration-dependent manner.Apoptosis inhibitor Z-VAD-FMK and antioxidant NAC could restore the cell viability,and NAC could reduce the accumulation of intracel-lular reactive oxygen species induced by PX-12 and restore the apoptosis induced by PX-12(P＜0.05).CONCLUSION:PX-12 induces apoptosis of hepato-cellular carcinoma cells through oxidative stress.
