title: Up-Regulation of microRNA-183 Promotes Cell Proliferation and Invasion in Glioma By Directly Targeting NEFL.
abstract: Glioblastoma multiforme (GBM) is the most common and lethal type of primary malignant brain tumor. In recent years, increasing reports suggest that discovery of microRNAs (miRNAs) might provide a novel therapeutical target for human cancers, including GBM. The expression and roles of microRNA-183 (miR-183) has been explored in several types of human cancers, including in GBM, and plays important roles in tumor initiation and progression. However, its biological functions in GBM remain largely unknown. In this study, we demonstrated that miR-183 was significantly up-regulated in astrocytoma tissues and glioblastoma cell lines. Introduction of miR-183 mimics into U251 cells could promoted, while its antisense oligos inhibited cell proliferation and invasion. Moreover, we identified neurofilament light polypeptide (NEFL) as a novel target gene of miR-183. The expression levels of NEFL are inversely correlated with that of miR-183 in human astrocytoma clinical specimens. In addition, NEFL-siRNA could significantly attenuate the inhibitory effects of knockdown miR-183 on the proliferation and invasion of U251 cells via mTOR signaling pathway. Overall, This study revealed that miR-183 promotes glioma cell proliferation by targeting NEFL, and also demonstrated that miR-183 could be a potential target for GBM treatment.
