Abstract

目的研究G蛋白信号调节子16(RGS16)与p53在人胶质瘤中表达及其相关性。方法利用免疫组织化学链霉亲合素生物素过氧化物酶复合物(SABC)法检测42例胶质瘤标本中RGS16与p53的表达。结果RGS16在10例胶质瘤旁正常脑组织有8例神经元阳性但胶质细胞阴性、42例胶质瘤中37例肿瘤细胞阳性,二者差异显著(P0.05);其中,RGS16与p53共同阳性表达11例,共同阴性表达1例,Kappa检验二者表达呈负相一致(P<0.05)。结论RGS16在胶质瘤中高表达而与病理分级无关,推测RGS16可能在胶质瘤发生中起作用。另外,胶质瘤中RGS16与p53表达呈负相关。 【英文摘要】 Objective To study the expression of RGS16 in human glioma and its relationship with p53. Methods The expression of RGS16 and p53 in protein level was studied by immunohistochemistry strept avidin-biotion-peroxidase-complex (SABC) method in 42 samples.Results In 10 normal brain tissues beside the human glioma, 8 cases expressed RGS16 in the neurons,but none in gliocytes; in 42 human gliomas, 37 cases expressed RGS16 in the glioma cells, and the difference between the normal tissue and the glioma was observe...军队医药卫生科研基金资助项目(02ma04);; 国家杰出青年自然科学基金资助项目(30125012);; 高等学校骨干教师及归国留学人员科研启动基金资助项目([1999]747
