Background: Glioma is one of the most malignant tumors worldwide. This study was aimed to study the effect of miR-379-5p/MGST1 on cell proliferation, migration, invasion and EMT in glioma.
Methods: RT-qPCR detected the expression of miR-379-5p and MGST1 in RNA level in glioma cell lines. Bioinformatic analysis was made to explore the associations between miR-379-5p and MGST1 while survival analysis was made with regards to MGST1 expression in glioma patients. Western blot analysis was applied to measure the EMT changes. MTT examined the cell viability. Transwell was used to detect the cellular invasion and migration. The binding sites between miR-379-5p and MGST1 were validated by luciferase reporter assays.
Results: miR-379-5p expression was lower in glioma cells. MiR-379-5p increase inhibited the viability, migration, invasion and EMT while inhibition of miR-379-5p showed a reverse effect. MGST1 inhibition curbed the cell functions. MiR-379-5p targeted and regulated MGST1 expression. Lower MGST1 is related to higher survival rate.
Conclusion: miR-379-5p could regulate glioma cell viability, migration, invasion and EMT through MGST1, suggesting that miR-379-5p/MGST1 axis might function in the regulation of glioma progression.
