ABSTRACT
@#Objective:
To explore the effect and possible mechanisms of has-miR-150-5p targeting HIF1α to regulate malignant biological behaviors of glioblastoma (GBM) U-251MG cells.Methods:
Real-time quantitative PCR (RT-PCR) was used to detect the expression of miR-150-5p and hypoxia inducible factor 1 (HIF1α) in U-251MG cells. Luciferase report assay was carried out to verify the biological relationship between miR-150-5p and HIF1α and their biological functions in U-251MG cells. The protein expressions of miR150-5pand HIF1α in U-251MG cells were detected by western blotting. The ability of cell migration was detected by wound healing test and cell invasion ability was detected by transwell test.Results:
After miR-150-5p mimic transfection, the mRNA expression of HIF1α was significantly reduced in U-251MG cells (P<0.01). Bioinformatics prediction and luciferase reporter assay demonstrated that miR-150-5p down-regulated HIF1α through directly binding to HIF1α 3’-untranslated region (3’-UTR) (all P<0.05). In U-251MG cells, miR-150-5p over-expression significantly inhibited HIF1α expression, cell invasion and migration (all P<0.05).Conclusion:
miR150-5p inhibits cell invasion and metastasis through negative regulation of HIF1α, indicating that miR-150-5p and HIF1α were both potential therapeutic targets for glioblastoma.
