PAI-1在人脑胶质瘤中的表达及意义分析
Expression and Clinical Significance of Plasminogen Activator Inhibitor Type-1 in Human Glioma
-
摘要: 目的 研究人脑胶质瘤组织中纤维蛋白溶解酶原激活剂抑制剂-1(PAI-1)的表达,旨在了解其与人脑胶质瘤恶性生物学行为之间的关系,并探讨其在人脑胶质瘤中的作用及其临床意义.方法 采用免疫组化(ABC法)及ECL-Western blot(增强化学发光蛋白印迹法)两种方法测定41例人脑胶质瘤手术切除标本及10例颅脑外伤患者内减压术中切除的正常脑组织标本中的PAI-1的蛋白表达水平.结果 PAI-1蛋白则随着人脑胶质瘤级别的升高表达水平逐渐升高,而在正常脑组织中表达水平极低,甚至不表达;正常脑组织组、低级别组人脑胶质瘤及高级别组之问表达的差异有统计学意义(P<0.05);PAI-1蛋白的表达水平与人脑胶质瘤的病理级别之间呈正相关(P<0.05).结论 PAI-1蛋白的高表可达反映人脑胶质瘤的恶性生物学行为,在人脑胶质瘤的发生过程中起着重要作用.
