摘 要: | 目的 探讨人脑胶质瘤中基质金属蛋白酶-9(MMP-9)、肿瘤干细胞标志物CD133蛋白的表达及临床意义.方法 采用免疫组织化学方法检测66例不同级别胶质瘤组织标本及15例正常脑组织标本中MMP-9、CD133蛋白表达.结果 人脑胶质瘤标本中MMP-9、CD133蛋白表达明显升高;CD133及MMP-9蛋白总的阳性细胞表达率随着胶质瘤病理级别的增加而增高(P〈0.01);人脑胶质瘤中CD133蛋白的阳性细胞表达率和MMP-9蛋白阳性细胞表达率成正相关(P〈0.01).结论 人脑胶质瘤中MMP-9、CD133蛋白的表达与脑胶质瘤的恶性程度密切相关;可能在脑胶质瘤的侵袭性生长、复发和转移过程中起协同作用.

Abstract: | Objective To study the expression and clinical significance of MMP -9 and CD133 protein in human gliomas. Methods Sixty - six cases of gliomas and fifteen cases of normal brain tissues were tested by immunohistochemistry for MMP - 9 and CD133 protein. Results The expression of CD133 and MMP -9 were significantly higher in human gliomas than that in normal brain tissues. It was shown that the MMP -9 and CD133 protein expression were closely correlated with the grade of gliomas. There was a positive reciprocity between the positive rates of CD133 and MMP - 9 protein in human gliomas(P 〈0. 01 ). Conclusion There is a close relationship between the higher levels expression of MMP -9, CD133 protein and the progression of gliomas, which may play important roles together in aggressive growth,relapse and metastasis of gliomas. |
