摘要 目的:探讨RNA干扰技术沉默survivin基因表达对人卵巢上皮癌A2780细胞增殖和凋亡的影响。方法:设计并合成靶向survivin的小分子干扰RNA(siRNA),构建慢病毒表达载体,MTT比色法检测细胞增殖率;流式细胞计数检测各组细胞周期和凋亡指数;Real-timePCR和Western blot方法观察对A2780细胞survivin mRNA水平及蛋白质表达的抑制效率。结果:survivin-siRNA能有效封闭survivin基因的表达,使survivin的mRNA相对水平明显降低(P<0.05);survivin-siRNA能明显抑制细胞增殖(P<0.05);survivin-siRNA使细胞G0/G1期细胞百分比明显增加,促进细胞的凋亡(P<0.05)。结论:利用RNA干扰技术沉默survivin基因的表达可以显著抑制人卵巢上皮癌A2780细胞的增殖,并在一定程度上诱导其自发凋亡,靶向survivin的RNA干扰技术在卵巢癌的基因治疗中具有一定的研究价值。
