摘要 目的探讨survivin基因小干扰RNA(siRNA)对肺癌细胞A549侵袭和Akt信号通路的影响。方法应用survivin siRNA转染处理人肺癌细胞系A549后,采用实时定量PCR和Western印迹检测survivin基因mRNA和蛋白水平,采用软琼脂集落培养试验检测锚着不依赖性增殖,采用Boyden小室模型试验检测癌细胞的侵袭能力,采用Western印迹检测Akt磷酸化水平。结果与对照组比较,转染组survivin基因mRNA和蛋白水平下调。Western印迹检测结果显示,转染组Akt磷酸化水平受到明显抑制。结论 survivin siRNA可抑制人肺癌细胞侵袭,抑制Akt磷酸化水平是其机制之一。
