Abstract

To examine the effect of GDM on the expression of MT1-MMP and u-PA genes in glioma cells. Glioma cell lines U251 and U87 were cultured in DMEM medium supplemented with 10% fetal bovine serum. RT-PCR was used to identify gene expression level. The level of u-PA mRNA was up-regulated significantly in the HGF group compared with the normal control group (P<0.05). The expression of MT1-MMP and u-PA was significantly lower in the GDM group than in the normal control and HGF groups (P<0.05). The expression of u-PA in the HGF+GDM group was down-regulated significantly compared with the normal control and HGF groups (P<0.05).GDM can inhibit expression of both MT1-MMP and u-PA in glioma cells.
