Abstract
MicroRNAs can function as oncogenes or tumor suppressors in glioma. Previously, we showed that miR-107 inhibits glioma cell proliferation, migration, and invasion. Since tumor growth and invasion are closely related to angiogenesis, we further examined the role of miR-107 in glioma angiogenesis. In a co-culture of glioma cells and human brain microvascular endothelial cells (HBMVEC), overexpression of miR-107 in glioma cells led to the inhibition of HBMVEC proliferation, migration, and tube formation ability. ELISA, RT-PCR, and western blot assays revealed that upregulation of miR-107 in glioma cells inhibits VEGF expression. Our findings collectively support the critical involvement of miR-107 in glioma cell angiogenesis and highlight its potential as a therapeutic target for glioma.
