摘要 目的探讨半乳糖凝集素-3(Galectin-3)、整合素ανβ3在脑胶质瘤细胞中的表达及意义。方法采用免疫组化法,检测5例正常脑组织及40例Ⅰ~Ⅳ级脑胶质瘤中的Galectin-3、整合素ανβ3蛋白表达,分析二者之间的关系。结果在正常脑组织中,Galectin-3、整合素ανβ3蛋白表达均呈阴性。脑胶质瘤患者的Galectin-3、整合素ανβ3蛋白表达主要在肿瘤细胞胞质及胞膜,Ⅰ、Ⅱ级脑胶质瘤的阳性表达率分别为39.13%、34.78%,阳性指数(LI)分别为(5.65±3.47)%、(5.35±3.46)%;Ⅲ、Ⅳ级脑胶质瘤的阳性表达率分别为76.47%、82.35%,LI分别为(27.88±22.13)%、(23.53±17.56)%。Galectin-3、整合素ανβ3蛋白阳性表达率呈正相关(r=0.966,P〈0.05)。结论 Galectin-3、整合素ανβ3蛋白表达与脑胶质瘤的恶性程度及进展有关,检测二者表达有利于人脑胶质瘤恶性生物学行为的判断。
