目的：检测胃癌及癌旁组织中 Wnt10b 的表达,探讨其与临床病理参数的关系。方法收集25例胃癌患者手术切除的癌组织及对应的癌旁组织,用实时荧光定量 PCR检测 Wnt10b mRNA的表达,Western-blot技术检测 Wnt10b蛋白的表达,分析 Wnt10b mRNA在胃癌组织中的表达与临床病理参数的关系。结果胃癌组织中 Wnt10b mRNA和蛋白表达水平明显高于癌旁组织(P<0.001),胃癌组织中 Wnt10b mRNA 表达阳性率与肿瘤远处转移相关(P<0.05),但与年龄、性别、肿瘤大小、TNM分期、分化程度和浸润深度无关。结论 Wnt10b在胃癌组织中呈活化状态,可能参与胃癌的发生发展。

Objective This study aimed to detect the expression of Wnt10b in paired tumor and non-cancerous tissues of gastric cancer (GC)patients and explore correlation of Wnt10b mRNA expression with the clinicopatho-logical parameters of GC.Methods The surgically resected paired cancerous and adjacent non-cancerous tissues of 25 GC patients were collected.The expression of Wnt10b mRNA was examined by Quantitative real-time PCR (qRT-PCR).Western-blot was employed to detect Wnt10b protein levels.Correlation between Wnt10b mRNA ex-pression and clinicopathological parameters was analyzed.Results The levels of Wnt10b mRNA in cancerous tis-sues were higher compared with matching adjacent non-cancerous tissues (P<0.001 ).The protein levels of Wnt10b were consistent with the expression levels of Wnt10b mRNA.Wnt10b mRNA expression was correlated with the lymph node metastasis of tumor (P<0.05),but no association was found between Wnt10b mRNA expres-sion and other clinicopathological parameters including age,gender,tumor size,TNM stage,differentitation stage and depth of invasion.Conclusion The expression levels of Wnt10b in cancerous tissues were higher than adjacent non-cancerous tissues,and there was correlation between the expression levels of Wnt10b and the lymph node me-tastasis of tumor.
