目的:研究青蒿琥酯诱导人胃癌SGC-7901细胞凋亡作用及其可能机制.方法:应用流式细胞术(FCM)、透射电镜(TEM)等方法检测不同浓度下青蒿琥酯对人胃癌SGC-7901细胞生长的影响,并应用Western Blot法检测凋亡相关基因Bcl-2、Bax的表达水平。结果:经青蒿琥酯处理后,人胃癌SGC-7901细胞凋亡率升高,并具有时间浓度依赖性(P lt;0.05),癌细胞被阻滞于G0/G1期;电镜观察肿瘤组织中散在凋亡细胞及凋亡小体;Western Blot法检测到凋亡相关基因Bcl-2表达减弱,Bax表达增强(P lt;0.05)。结论:青蒿琥酯能有效抑制人胃癌SGC7901细胞增殖并诱导其凋亡,其机制可能与下调凋亡相关基因Bcl-2、上调Bax表达有关。
