摘要
目的:探讨人脑胶质瘤中多种基因蛋白的异常表达及意义。方法:应用免疫组化技术检测102例手术切除人脑胶质瘤组织标本中增殖细胞核抗原(PCNA)及p53,p21ras及EGFR蛋白的表达。胶质瘤组织PCNA标记指数(PCNALI)为556±155,p53,p21ras及EGFR蛋白的表达率分别为586%,523%,42%,均显著高于正常脑组织。PCNALI及EGFR蛋白表达与胶质瘤恶性程度相关(P<001),p53,p21ras及EGFR蛋白的表达与胶质瘤恶性程度无关(P>005)。胶质瘤中PCNALI与EGFR蛋白表达无明显相关(P>005),而与p53和p21ras表达相关(P<005)。结论:p53,p21ras和EGFR异常表达与胶质瘤的发生发展相关,PCNALI是评估增殖活性的良好指标。
