摘要: 目的 探讨臭椿酮(AIL)对非小细胞肺癌顺铂耐药细胞系A549/DDP的增敏作用。方法 采用MTT检测AIL对A549和A549/DDP细胞活力的影响;Chou-Talalay中效法分析臭椿酮与顺铂的联合用药指数(CI);流式细胞术检测细胞周期及凋亡,Western blotting法检测凋亡相关蛋白表达水平。结果 AIL(0.6μmol/L)与DDP(50μg/mL)联合用药有协同作用;细胞周期阻滞在G1期,同时细胞凋亡率升高;Caspase-3和 Bcl-2蛋白表达下降,Cleaved Caspase3、Bax、CDK4和CyclinD1的蛋白表达升高。结论 AIL可增强A549/DDP细胞对DDP的敏感性,协同DDP抑制A549/DDP细胞的生长,促进其凋亡。

Abstract: Objective To investigate the sensitization effect of Ailanthone (AIL) on cisplatin-resistant A549/DDP cells of non-small cell lung cancer. Methods The effects of AIL on the viability of A549 and A549/DDP cells were detected by MTT. Analysis of the combined drug use index(CI) of Ailanone and cisplatin using Chou-Talalay. Cell cycle and apoptosis were detected by flow cytometry, and the expression of apoptosis-related proteins were detected by Western blotting. Results AIL (0.6μmol/L) and DDP (50μg/mL) had synergistic effect. Cell cycle arrest and apoptosis rate increased in G1 phase. The protein expression of caspase-3 and bcl-2 decreased, but the protein expression of Cleaved Caspase3, Bax, CDK4 and CyclinD1 increased. Conclusion AIL enhanced the sensitivity of DDP to A549/DDP, and increased the growth inhibition and apoptosis of DDP on A549/DDP.
