摘要: 目的: 探讨survivin基因在人原发性肝癌发生发展中的作用及可能的机制。方法:应用逆转录聚合酶链反应(RT-PCR)法检测15例原发性肝癌患者的肝癌组织、癌旁组织及肝正常组survivin基因及相关基因c-myc、p53、STAT3和VEGF的mRNA表达水平,应用Western blotting法及免疫组织化学染色法检测上述组织中survivin基因的蛋白表达水平及其定位。结果: 肝癌组织及癌旁组织中survivin基因mRNA的表达量均显著高于正常肝组织(P<0.01), 肝癌组织中survivin基因mRNA的表达量明显高于癌旁组织(P<0.01),肝癌及癌旁组织中c-myc、 STAT3、VEGF基因mRNA的表达量均显著高于正常肝组织(P<0.01),而p53基因mRNA的表达量显著低于正常肝组织(P<0.01)。肝癌组织及癌旁组织中survivin基因的蛋白表达水平均显著高于正常肝组织(P<0.01),且肝癌组织中survivin基因的表达水平显著高于癌旁组织(P<0.01)。结论:survivin基因的异常表达在肝癌的发生发展中起促进作用,可作为治疗的理想靶点。

Abstract: To explore the role and possible mechanism of survivin gene during the progress of originating and developing of human hepatocellular carcinoma(HCC). Methods Reverse transcriptase-polymerase chain reaction(RT-PCR) was used to detect mRNA expressions of survivin and related genes included STAT3,c-myc,p53 and VEGF in HCC tissues,tissues surrounding tumor and normal tissues of fifteen HCC cases.The protein expression of survivin gene was detected by Western blotting and immunohistochemical method.Results The mRNA expression levels of survivin gene in HCC tissues and tissues surrounding tumor were significant higher than that in normal liver tissues(P<0.01),and there was also significant difference between HCC tissues and tissues surrounding tumor (P<0.01).The mRNA expressions of c-myc,STAT3 and VEGF genes were up-regulated while the mRNA expression of p53 was down-regulated in HCC tissues and tissues surrounding tumor compared with normal tissues (P<0.01), there was also significant difference between HCC tissues and tissues surrounding tumor (P<0.01).The expression levels of survivin protein in HCC tissues and tissues surrounding tumor were higher than that in normal liver tissues (P<0.01), there was also significant difference between HCC tissues and tissues surrounding tumor (P<0.01).Conclusion The persistent activation of survivin gene plays a promotion role in the carcinogenesis of HCC,and survivin gene may act as a new target in therapy of HCC.
