目的:研究青蒿琥酯誘導(dǎo)人胃癌SGC-7901細(xì)胞凋亡作用及其可能機(jī)制.方法:應(yīng)用流式細(xì)胞術(shù)(FCM)、透射電鏡(TEM)等方法檢測(cè)不同濃度下青蒿琥酯對(duì)人胃癌SGC-7901細(xì)胞生長(zhǎng)的影響,并應(yīng)用Western Blot法檢測(cè)凋亡相關(guān)基因Bcl-2、Bax的表達(dá)水平。結(jié)果:經(jīng)青蒿琥酯處理后,人胃癌SGC-7901細(xì)胞凋亡率升高,并具有時(shí)間濃度依賴性(P lt;0.05),癌細(xì)胞被阻滯于G0/G1期;電鏡觀察腫瘤組織中散在凋亡細(xì)胞及凋亡小體;Western Blot法檢測(cè)到凋亡相關(guān)基因Bcl-2表達(dá)減弱,Bax表達(dá)增強(qiáng)(P lt;0.05)。結(jié)論:青蒿琥酯能有效抑制人胃癌SGC7901細(xì)胞增殖并誘導(dǎo)其凋亡,其機(jī)制可能與下調(diào)凋亡相關(guān)基因Bcl-2、上調(diào)Bax表達(dá)有關(guān)。
