目的探討生長抑素類似物8肽(SS8)對人原發(fā)性肝癌細胞凋亡和cmyc蛋白表達的影響。方法體外培養(yǎng)肝癌細胞SMMC7721,用10 μg/ml SS8處理后,流式細胞儀檢測肝癌細胞凋亡率和cmyc蛋白的表達。結果與對照組相比,SS8使實驗組S期和G2/M期細胞數減少、G0/G1期細胞數增加,兩組細胞的凋亡率分別為6.1%和14.2%,差異有顯著性意義(P<0.05)。經SS8作用24 h后,實驗組cmyc蛋白表達水平為0.833±0.035,與對照組相比差異無顯著性意義(P>0.10),而在SS8作用48、72、96、120和144 h后,實驗組cmyc蛋白表達水平分別為0.818±0.04、0.721±0.029、0.669±0.026、0.648±0.045和0.642±0.028,較對照組顯著降低(P<0.05)。結論SS8有誘導肝癌細胞SMMC7721凋亡和降低cmyc蛋白表達的作用。
