[Expression of CD147 and MMP-2 in human gliomas and its correlations with prognosis].

OBJECTIVE: To investigate the expressions of CD147 and MMP-2 in human gliomas and to study the relationship between their expression and prognosis. METHODS: Immunohistochemistry SP methods were applied to detect the expression of CD147 and MMP-2 in 50 cases of gliomas and RT-PCR also applied to analyze the expression level of CD147 mRNA. The relationship between the expression level and the glioma prognosis were analyzed statistically depends on the follow-up investigation of the disease development. RESULTS: The positive rates of CD147 and MMP-2 in human gliomas were 72. 0% and 78. 0%, and coexpression of CD147 and MMP-2 in gliomas was 70. 0%. CD147 protein was positively correlated with the expression of MMP-2 protein (r =0. 737, P<0. 01). CD147 mRNA expression was also detected in low and high grade gliomas by RT-PCR, but their expression levels were obviously enhanced in high grade gliomas. There was a significant difference in each grade gliomas. The higher expression of CD147, the shorter survival time of the patients. The variations were significant statistically. CONCLUSION: There was positive correlation between the expressions of CD147, MMP-2 in human gliomas and the degree of malignancy and prognosis. CD147 and MMP-2 may be a prognostic factor of human gliomas and targets for chemotherapeutical strategies.
