Abstract:
Recently, increasing studies have suggested that miRNAs play a significant role in the occurrence and development of glioma. More researches are needed to explore the role of miRNAs in glioma, which will help to find new therapeutic targets. miR-212-5p has been reported to be involved in the progression in many cancers. However, whether miR-212-5p has a regulative effect on glioma remains un clear. In this study, we aimed to explore the effect of miR-212-5p on glioma development and its mechanism. Here, we demonstrated that miR-212-5p was lowly expressed in glioma cell. miR-212-5p suppressed the glioma cell proliferation, inhibited the migratory and invasive capabilities and promoted apoptosis in glioma cells. Besides, miR-212-5p also inhibited tumor growth in vivo. We found small ubiquitin-like modifier 2 (SUMO2) was the target of miR-212-5p, and miR-212-5p suppressed SUMO2 expression to regulate the proliferation, migration, and apoptosis of glioma cells. These findings indicated that miR-212-5p may be a possible therapeutic target for the treatment for glioma.
Insights
MicroRNA-212-5p (miR-212-5p) is downregulated in glioma. This microRNA inhibits glioma cell proliferation, migration, and invasion, suggesting its potential as a therapeutic target.

When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...
