OBJECTIVES: To explore the role of SEPT7 in glioma cell invasion. METHODS: SEPT7 was transfected into human glioma cell lines U251 and TJ899, the invasive abilities were evaluated by transwell assay, scratch assay, and 3-D/2-D Matrigel growth. The expression of MMP2/9, MT1-MMP, integrin alpha(v)beta(3), and TIMP1/2 was detected by immunohistochemistry, immunofluorescence, and Western blot analyses. Distribution of alpha-tubulin was examined by laser scanning confocal analysis. RESULT: After SEPT7 trasfection, cell invasion was inhibited, expression of MMP2/9, MT1-MMP, and integrin alpha(v)beta(3) was decreased, while TIMP1/2 was increased, and alpha-tubulin was redistributed. CONCLUSION: These results suggest that SEPT7 plays an important role in the glioma cell invasion.
