背景与目的:FGFR2是受体型酪氨酸激酶,c～cbl是泛素一蛋白酶体通路中的一个新的RINGFinger型泛素连接酶,本研究探讨FGFR2和c-Cbl在胃癌组织中的表达及其临床意义.方法:构建胃痛组织芯片,应用免疫组化SP法,检测两种蛋白的表达情况.结果:FGFR2和c-Cbl在胃癌组织中的阳性表达率分别为77.4%和71.0%.FGFR2蛋白表达与浸润深度及病珲分期有关(P<0.05),而与性别、年龄、分化程度及淋巴结转移无关;c-Cbl蛋白表达与浸润深度及病理分期有关(P<0.05),而与性别、年龄、分化程度及淋巴结转移无关.FGFR2与C-Cbl的表达强度呈正相关.结论:FGFR2和c-Cbl在胃痛中高表达;FGFR2及C-Cbl蛋白的表达强度与胃痛的浸润深度及病理分期均呈正相关:FGFR2与C-Cbl的表达强度均呈正相关.%Background and purpose: FGFR2 is a receptor tyrosine kinase and c-Cbl is a new RING finger type of ubiquitin ligase in the ubiquitin-proteasomes path. The purpose of this study was to evaluate the expression and significance of FGFR2 and c-Cbl in gastric carcinoma. Methods: The expression of FGFR2 and c-Cbl were detected by immunohistochemical method of SP. Results: The positive expression rates of FGFR2 and c-Cbl were 77.4%,71.0% in gastric carcinoma, respectively, both were higher than those normal tissue (P<0.05);The expression of FGFR2 and c-Cbl were positively correlated with depth of invasion and TNM staging, and there was a positive relationship between the expressions of FGFR2 and c-Cbl. Conclusion. The expressions of FGFR2 and c-Cbi were associated with some clinicopathologic features in gastric carcinoma, indicating that their expression may be the prognostic factors for gastric carcinoma.
