摘要: 目的 研究雷公藤甲素对人肺腺癌A549 细胞增殖和凋亡的影响。方法 采用MTT 实验检测雷公藤甲素对体外培养的人肺腺癌A549 细胞增殖的影响, 运用流式细胞术、基因组DNA 电泳观察凋亡特征性“梯状”条带检测细胞凋亡, 采用caspase 活性定量检测试剂盒分析caspase-9, 3 的活化。结果 雷公藤甲素对体外培养的A549 细胞具有明显的抑制作用。流式细胞仪检测显示雷公藤甲素可以显著诱导A549细胞凋亡, DNA 电泳显示雷公藤甲素作用于A549细胞后出现凋亡细胞特有的DNA 阶梯状条带。雷公藤甲素作用后A549细胞caspase-9, caspase-3 活性明显升高。结论 雷公藤甲素可能通过线粒体信号通路抑制肺腺癌A549细胞的生长并诱导其凋亡。

Abstract: AIM: To study the effect of triptolide on cell proliferation and apoptosis in A549 human lung cancer cell.METHODS: The effect of triptolide on cell viability in A549 cell was evaluated by MTT assay.Cell apoptosis was observed by flow cytometry and DNA ladder analysis.Activities of caspase-9 and caspase-3 were assayed with caspase colorimetric assay kit.RESULTS: Triptolide( eg., 0.5 -4.0 μg·ml-1)inhibited cell growth and induced apoptosis in a dose-dependent way at 24 h in A549 cells.The activation of caspase-9 and caspase-3 was significantly increased at 24 h in A549 cells when exposed to triptolide ( eg., 0.5 -4.0 μg·ml-1).CONCLUSION: Triptolide induces apoptosis in A549 cells partly through mitochondrial signal transduction pathway.

Key words: triptolide, lung cancer, apoptosis
