目的:研究青蒿琥酯誘導人胃癌SGC-7901細胞凋亡作用及其可能機制.方法:應用流式細胞術(FCM)、透射電鏡(TEM)等方法檢測不同濃度下青蒿琥酯對人胃癌SGC-7901細胞生長的影響,并應用Western Blot法檢測凋亡相關基因Bcl-2、Bax的表達水平。結果:經(jīng)青蒿琥酯處理后,人胃癌SGC-7901細胞凋亡率升高,并具有時間濃度依賴性(P lt;0.05),癌細胞被阻滯于G0/G1期;電鏡觀察腫瘤組織中散在凋亡細胞及凋亡小體;Western Blot法檢測到凋亡相關基因Bcl-2表達減弱,Bax表達增強(P lt;0.05)。結論:青蒿琥酯能有效抑制人胃癌SGC7901細胞增殖并誘導其凋亡,其機制可能與下調(diào)凋亡相關基因Bcl-2、上調(diào)Bax表達有關。
