MiRNA-93 functions as an oncogene in glioma by directly targeting RBL2.
OBJECTIVE: Glioma is a tumor of the brain. Although the clinical regimens and surgical techniques for glioma have improved, therapies of advanced glioma remain challenging, carrying dismal overall survival and therapeutic success rates. Evidence has shown that miRNAs played important roles in glioma development. The current study aimed at investigating the function of a novel cancerogenic miRNA, miR-93, in glioma progression by investigating the expression and mechanism of it.
PATIENTS AND METHODS: qRT-PCR was conducted to assess the miR-93 expression and the mRNA expression of target gene in glioma tissues and cells. The invasion and migration abilities of the glioma cells were determined by transwell assays. Luciferase reporter assay was performed to confirm the target of miR-93.
RESULTS: The results indicated that miR-93 expression in glioma tissues and cells was increased significantly than that in normal brain tissues and cells. Furthermore, miR-93 promoted glioma cell migration and invasion. RBL2 was recognized as a direct target of miR-93 in glioma cells, and overexpression of RBL2 could reverse the stimulative effect of miR-93 in glioma cell.
CONCLUSIONS: The above findings suggested that miR-93 together with RBL2 could be diagnostic targets and novel prognostic markers for glioma.
