摘要 目的探讨Hedgehog信号通路分子Shh及其下游转录因子Gli1与Foxm1在胃癌中的表达,进一步阐明其与临床病理特征的关系。方法应用免疫组化法检测70例胃癌和30例胃正常黏膜中Shh、Gli1和Foxm1的表达,并分析胃癌组织中Shh、Gli1、Foxm1蛋白表达与临床病理因素的关系及其相关性。结果 Shh、Gli1、Foxm1蛋白在胃癌组织中阳性表达率显著高于在正常胃黏膜组织(P<0.05)。三者的表达均与年龄、性别、肿瘤大小、浸润深度无明显相关(P>0.05)。Shh的在胃癌中的表达与组织分化程度、TNM分期、淋巴结转移相关(P<0.05)。Gli1的表达与组织的分化程度及有无淋巴结转移相关(P<0.05)。而Foxm1的表达只与胃癌有无淋巴结转移相关(P<0.05)。相关性分析显示Shh与Glil呈正相关(rs=0.818,P<0.05),Shh与Foxm1呈正相关(rs=0.615,P<0.05),Glil与Foxm1呈正相关(rs=0.897,P<0.05)。结论 Shh、Gli1、Foxm1三者在胃癌中呈高表达,三者在胃癌的发生发展过程中具有协同及相互调节作用,Shh、Gli1、Foxm1三者可以作为胃癌早期诊断、判断预后的指标,同时为临床开发新药物及临床化疗提供理论基础。
