摘要 目的:探讨Wnt2B基因在胃癌组织及相应癌旁组织中的表达及其意义。方法:采用逆转录多聚酶链式反应(RT-PCR)技术检测胃癌组织及相应癌旁组织中Wnt2B基因mRNA的表达水平。结果:Wnt2B基因在37例人类胃癌组织及相应癌旁组织中均有表达,阳性率达100%;Wnt2B基因在胃癌组织中的表达水平明显高于相应癌旁组织,差异具有统计学意义(P<0.001)。结论:Wnt2B基因可能参与了胃癌的发生发展过程,在胃癌组织中表达上调可能有助于胃癌的早期诊断。 Objective:To inv estigate the expression of Wnt2B gene in gastric carcinoma tissues and the corresponding paracarcinoma tissues and explore the relationship between the Wnt2B gene and gastric carcinogenesis.Methods: Total RNA was extracted from 37 cases of human gastric carcinoma tissues and the corresponding para-carcinoma tissues, and the levels of Wnt~ gene mRNA expression were evaluated by Reverse transcription-polymerase chain reaction (RT-PCR). Results: The expression of Wnt2B gene mRNA could be detected in all the cases of gastric carcinoma tissues,and the corresponding para-carcinoma tissues. The level of Wnt2B gene mRNA expression in gastric carcinoma tissues was significantly up-regulated (P〈0.001). Conclusion: Wnt2B gene participates in the gastric carcinogenesis. The up-regulated expression of Wnt2B gene mRNA during gastric carcinoma tissues may be of benefit for its prognosis.
