摘要
目的 研究siRNA对肝癌细胞株HepG2中Survivin基因表达的抑制作用。方法 设计、合成一对Survivin编码基因的反向重复序列 ,中间间隔 9个核苷酸序列 ,通过定向克隆至载体Psilencer2 1,构建siRNA真核表达载体 ,经稳定转染HepG2细胞后应用RT PCR及流式细胞术检测肝癌细胞中Survivin基因mRNA及蛋白质表达的抑制情况。结果 测序证实siRNA真核表达载体构建成功。通过RT PCR及流式细胞术检测 ,siRNA在mRNA及蛋白质水平抑制Sur vivin基因表达分别达 73%和 75 %。结论 构建的Psilencer (+) Survivin重组质粒能有效抑制Survivin基因在肝癌细胞株HepG2中的表达。为肿瘤的生物学治疗提供了新的方法和材料。
