Expressions of aquaporin-4, matrix metallo-proteinase-2 and matrix metallo-proteinase-14 in peritumor edematous zone of glioma and clinical implications

To distinguish the expressions of matrix metallo-poteinase and aquaporin in peritumor edematous zone and normal brain tissue for different pathological levels of glioma and explore the relationship of glioma cell invasiveness and brain edema. The immunohistochemical method of SP was employed to dete...

description To distinguish the expressions of matrix metallo-poteinase and aquaporin in peritumor edematous zone and normal brain tissue for different pathological levels of glioma and explore the relationship of glioma cell invasiveness and brain edema. The immunohistochemical method of SP was employed to detect the expressions of aquaporin-4 (AQP-4), matrix metallo-proteinase-2 (MMP-2) and matrix metallo-proteinase-14 (MMP-14) in glioma and normal brain tissue. Due to a rarity of glioma Grades I and II, grades I and II glioma were pooled into low malignancy group (LMG) and grades III and IV into high malignancy group (HMG). The software program SPSS 11.0 was used for Kolmogorov-Smirnov test of independent samplets. The differences were detected between normal brain tissue and LMG and HMG. Also the relationship of AQP4, MMP-2 and MMP-14 was analyzed. With the advancing pathological grades of glioma, the expression of AQP-4, MMP-2 and MMP-14 were higher in positive areas. There were significant deviations among 3 groups.
