- W1011776285 abstract "目的 研究青蒿琥酯（artesunate,Art）体外诱导人肺腺癌A549细胞凋亡及对半胱天冬氨酸蛋白酶9（cysteine containing aspartate9,caspase-9）和caspase-3活性的影响。方法 Art处理A549细胞,流式细胞计数（Flow Cytometry,FCM）检测细胞周期和细胞凋亡,比色法检测caspase-9活性,westernblot检测caspase-3变化。结果 FCM显示A549细胞经100mg/L Art作用24h,出现S期细胞减少（P〈0.01）,G2/M期细胞数目增多（P〈0.01）,细胞凋亡率增加（P〈0.0）。不同浓度（10mg/L、25mg/L、50mg/L、100mg/L）的Art作用A549细胞24h,caspase-9活性呈浓度依赖性增加,分别为对照组的9.87倍、23.33倍（P〈0.01）、38.47倍（P〈0.01）和60.47倍（P〈0.01）。Western blot显示A549细胞经100mg/L Art作用6、12、24h后,细胞浆中caspase-3活化,分别为对照组1.2倍、1.6倍（P〈0.01）、1.8倍（P〈0.01）。结论 青蒿琥酯可通过增加caspase-9和caspase-3的活性,诱导A549细胞凋亡,为阐明Art的抗癌机理,指导青蒿琥酯用于肿瘤治疗提供实验依据。" @default.
