Abstract: 目的探讨Survivin基因在胰腺癌中的表达及与bcl-2、p53蛋白表达的相互关系.方法用RT-PCR法检测49例胰腺癌、5例慢性胰腺炎和12例正常胰腺组织中Survivin mRNA的表达,免疫组织化学法检测胰腺癌中bcl-2、p53蛋白表达.结果 Survivin mRNA在胰腺癌中表达率为76%,在慢性胰腺炎及正常胰腺组织中不表达(P<0.05).Survivin基因表达与胰腺癌的分化程度、临床分期及淋巴结转移无相关性(P>0.05).Survivin基因表达与bcl-2蛋白表达不相关,与p53蛋白表达显著相关.结论 Survivin基因在胰腺癌中过度表达,提示该基因对胰腺癌发生和发展起重要作用;抑癌基因p53的失活与Survivin基因的表达可能在胰腺癌的发生中起协同作用.
