Abstract

Objective: To further explore the mechanism of paclitaxel-induced apoptosis of human hepatocellular carcinoma cell line HepG2 based on previous studies. Methods: ①After paclitaxel was applied to HepG2 cells, the colorimetric method was used to determine the changes of SOD activity, MDA content, and GSH content in HepG2 cells.②The effect of paclitaxel on mitochondrial membrane potential of HepG2 cells was detected by JC-1 staining at different times. Results: ①After HepG2 cells were treated with 5, 10, 20, 40, 80 μg•L-1 paclitaxel for 48 h, the MDA content gradually increased, SOD activity and GSH content gradually decreased, and the concentration was dependent.②JC-1 staining method detected that the mitochondrial membrane potential of HepG2 cells gradually decreased after 24h, 36h, and 48h of 80μg•L-1 paclitaxel on HepG2 cells, and there was a certain time dependence. CONCLUSION: Paclitaxel disrupts the oxidative equilibrium in HepG2 cells, causes oxidative stress in normal metabolic disorders of the cells, thereby oxidatively damages cells, and induces apoptosis in HepG2 cells.
