摘要 目的研究Dickkopf-1蛋白及β-catenin蛋白在舌癌中的表达与舌癌临床病理特征的关系。方法应用免疫组织化学SP法检测60例舌癌组织,30例正常舌黏膜组织中Dickkopf-1的阳性表达和β-catenin的异常表达,分析它们与舌癌临床病理指征的关系,及二者表达改变对舌癌的侵袭能力和Wnt/β-catenin信号通路活性的影响。结果舌癌中Dickkopf-1蛋白的阳性表达低于正常舌黏膜组织(P<0.01),β-catenin蛋白的异常表达高于正常舌黏膜组织(P<0.01);Dickkopf-1和β-catenin蛋白在舌癌中的表达与肿瘤分化程度、临床分期及有无淋巴转移有关(P<0.01)。舌癌中Dickkopf-1的阳性表达与β-catenin的异常表达呈负相关(r=-0.529,P<0.01)。结论 Dickkopf-1和β-catenin蛋白的异常表达或缺失与舌癌的发生和发展密切相关,其机制可能与活化Wnt/β-atenin信号通路有关。
