ABSTRACT
Objective To explore the apoptosis of K562/G01 cells induced by triptolide through MDM2/p53 signaling pathway. Methods K562/G01 cell line was treated with different concentrations of triptolide. MTT was used to detect the cell proliferation inhibition rate. FCM was used to determine the apoptosis rate changes in 12 h and 24 h. The mRNA expression levels of bcr-abl, XIAP, MDM2, p53 were detected by real-time quantitative PCR. Results After treatment by 10, 20, 40, 80, 100 nmol/L TP in 12, 24, 48 h, the viability of K562/G01 cells was inhibited in time-dose dependence manner. K562/G01 cells was treated by 20 nmol/L, 40 nmol/L TP after 12 h, 24 h, the cell apoptosis rate was rising with drug concentration and time. The bcr-abl, XIAP, MDM2 mRNA expression was down-regulated and p53 mRNA expression was up-regulated by TP. Conclusion TP can inhibit the growth of K562/G01 cell line and induce apoptosis through XIAP-MDM2-p53 signaling pathway.
