Survivin反义寡核苷酸对人卵巢癌细胞株IL-6/STAT3信号通路的影响和意义
摘要:目的通过分析人卵巢癌细胞株转染Survivin反义寡核苷酸(As0DN)后IL-6/STAT3信号通路及其下游相关癌基因的表达以及其侵袭能力的改变,探讨Survivin ASODN在抑制人卵巢癌细胞转移中的可能作用、机制和临床价值。方法脂质体(Lipofectamine 2000)介导SurvivinASODN转染人卵巢癌SKOV3细胞株(实验组),同时设空脂质体对照,Transwell小室检测细胞株侵袭能力的改变,荧光定量PCR检测两组细胞株中白细胞介素6(IL-6)、信号转导与活化因子3(STAT3)、Survivin、血管内皮生长因子(VEGF)基因的表达,Westernblot检测IL-6、STAT3、磷酸化的信号转导与活化因子3(p-STAT3)、Survivin、VEGF-A蛋白的表达。结果实验组细胞株中IL-6、STAT3、Survivin、VEGF基因表达均较对照组明显下调(P〈0.05);实验组细胞株中IE-6、STAT3、p-STAT3、Survivin、vEGF-A蛋白表达均较对照组明显下调(P〈0.05)。实验组细胞株侵袭能力较对照组明显下降(P〈0.01)。结论ASODN靶向抑制Survivin可有效降低人卵巢癌细胞侵袭转移能力,抑制IL-6/STAT3信号通路及其下游相关致癌基因的表达活性。Survivin ASODN可能在防治卵巢癌复发和转移治疗中有临床价值。
