Abstract:

Objective To investigate the effect of miR-378-5p on glioma angiogenesis and its molecular mechanism. Methods The expression of miR-378-5p were detected by qRT-PCR in four glioma cells. The levels of VEGF were analyzed by ELISA. HUVECs were treated conditioned medium which collected by glioma cells supernatant. The effects of miR-378-5p on the proliferation, migration, invasion, and angiogenesis of HUVECs were detected by CCK-8, Transwell assay, and tubular formation assay. Results U251 was the highest expression of miR-378-5p, while U87 MG was the lowest expression. Glioma-conditioned media increased miR-378-5p levels significantly promoted the proliferation, migration, invasion, and angiogenesis of HUVECs. The results were contrary with glioma-conditioned media decreased miR-378-5p levels. miR-378-5p promoted the release of VEGF-A from glioma cells. The proliferation, migration, invasion, and angiogenesis of HUVECs treated-VEGF neutralizing antibody were significantly downregulated. Conclusion miR-378-5p promoted HUVECs proliferation, migration, invasion, and angiogenesis by increasing the release of VEGF from glioma cells.

Key words: microRNA-378-5p, glioma, angiogenesis, VEGF-A
