摘要 目的探讨Survivin基因沉默对脑胶质瘤细胞株C6体外细胞增殖、细胞周期和凋亡的影响。方法设计并合成针对Survivin基因的siRNA,构建Survivin-shRNA和阴性对照shcontrol慢病毒表达载体并感染脑胶质瘤C6细胞,用Western Blot法检测感染后C6细胞Survivin蛋白表达的抑制率,MTT法观察感染后24、48和72 h细胞增殖的变化,流式细胞术检测感染后48 h细胞凋亡和细胞周期的改变。结果 Survivin shRNA慢病毒载体感染C6细胞后Survivin蛋白的抑制率约为80%,阻滞C6细胞由G1期进入S期,抑制细胞的生长,增加了细胞的凋亡。结论 Survivin shRNA慢病毒表达质粒特异高效地抑胶质瘤C6细胞Survivin基因的表达,阻断C6细胞的细胞周期,抑制其增殖并促进凋亡。
