摘要: 目的 通过检测PPARγ和p27kip1、Skp2三种蛋白在HCC中的表达情况,探讨PPARγ和p27kip1、Skp2蛋白在肝癌发生发展过程中的作用 。方法 收集河北医科大学第四医院病理证实的肝细胞癌组织标本57例和20例正常肝组织标本。随访截止时间为2011年1月1日。结合随访资料探讨PPARγ、P27kip1及Skp2蛋白在肝癌中表达的临床意义。结果 统计学相关分析显示:在肝细胞癌组织中,PPAR-γ蛋白与Skp2、P27kip1蛋白表达无相关性(P>0.05); Skp2与P27kip1蛋白的表达呈显著负相关 (r=-0.307,P=0.020)。Skp2蛋白低表达组的1、3、5年生存率显著高于高表达组(χ2=14.718,P=0.000)。结论 在肝细胞癌组织中,PPAR-γ蛋白的阳性表达率和Skp2蛋白的高表达率明显升高,P27kip1蛋白的阳性表达率明显下调,并与肝细胞癌的恶性生物学行为密切相关,Skp2与P27kip1蛋白的表达呈显著负相关,Skp2可作为判断肝细胞癌预后的指标。

Abstract: Objective The aim of this expriment is to investigate the expression and significance of PPARγ, p27kip1 and Skp2 in hepatocellular carcinoma. Method Immunohistochemistry was performed for PPAR-γ, p27Kip1, and Skp2 in 57 cases HCC patients who had undergone operations at the Fourth Hospital of Hebei Medical University, between 2004 and 2007. Results A significant inverse correlation was found between p27Kip1 andSkp2 expression in HCC(r=-0.307,P=0.020).There was no significantcorrelation between PPAR-γ and P27kip1、Skp2 expression in HCC. Conclusion The expression of Skp2 was negatively correlated with P27kip1 in HCC,High Skp2 expression was significantly associated with poor prognosis. Skp2 might serve as the key prognostic factors in HCC.
