RESUMEN

Aim To explore the mechanism of timosaponin A III increasing cisplatin sensitization of non-small cell lung cancer cisplatin-resistant A549/DDP cells. Methods The cell proliferation was detected by CCK8,the cell apoptosis was detected by Annexin V/ PI,and the cell cycle distribution was measured by PI. The effect of the combined drug on cell proliferation was detected by cell clone formation. The mRNA expression levels of C-myc, cysteinyl aspartate-specific protease-3 (caspase-3) were detected by reverse transcription polymerase chain reaction (RT-PCR). Western blot and Flow Cytometry were performed for the mechanism study. Results The results of CCK8 and clone formation showed that the timosaponin AM group significantly increased the sensitivity of cisplatin to A549/DDP cells. Compared with the cisplatin group a-lone,the combination of timosaponin AM and cisplatin significantly elevated the apoptosis rate of A549/DDP cells (P < 0.05) , induced cell cycle arrest in G
