摘要: [摘要] 目的 研究青蒿琥酯诱导食管癌细胞凋亡作用及探讨青蒿琥酯抗食管癌作用机制。方法 不同浓度的青蒿琥酯(Artesunate, Art)(0、10、20、40μg/ml) 作用Eca109细胞24h,流式细胞术(Flow cytometry, FCM)方法检测细胞凋亡、周期及细胞中bcl-2和bax蛋白的表达量。结果 青蒿琥酯作用Eca109细胞24h后,与对照组相比,细胞凋亡率显著增高P<0.05,且具有剂量依赖性。青蒿琥酯组与对照组相比,Eca109细胞中bcl-2蛋白表达水平及细胞增殖指数显著降低P<0.05,而bax蛋白表达量显著增高P<0.05,且具有剂量依赖性。结论 青蒿琥酯可以通过调节Eca109细胞中bcl-2、bax蛋白表达水平和细胞增殖,从而诱导Eca109细胞产生凋亡,起到抗食管癌作用。

Abstract: [Abstract] Objective To research inducing apoptosis function of artesunate and explore the mechanism of inhibition effect of artesunate on esophageal cancer. Methods Cell apoptosis, cell cycle, bcl-2 and bax protein expression level of Eca109 cells after the treatment of various concentration of artesunate(Art) (0、10、20、40μg/ml) for 24h were detected by flow cytometry(FCM). Results Cell apoptosis of Eca109 cells was significantly increased after the treatment of Art for 24h (P<0.05). The Eca109 cell bcl-2 protein expression level and cell proliferation index(PI) of Art group were lower than control group (P<0.05), but the bax protein expression level was higher in a concentration-dependent manner. Conclusion Artesunate have the inhibition effect to esophageal cancer by regulating the bcl-2, bax protein expression level and cell proliferation so inducing cell apoptosis.
