Emerging evidence reveal that long noncoding RNAs (lncRNAs) participates in the epigenetic regulation of pathophysiological process. However, the deepgoing role of lncRNAs on meningioma is still unclear. In present study, we investigate the roles of lncRNA LINC00460 in meningeoma tissue and uncover its molecular mechanism. Results revealed that LINC00460 expression level was significantly up-regulated in meningeoma tissues and malignant meningeoma cell lines (IOMM-Lee, CH157-MN). Mechanically, loss-of-function assays showed that LINC00460 knockdown significantly suppressed the proliferation ability, increased the apoptosis and decreased the proteins (MMP-2, MMP-9, ZEB1) expression. Bioinformatics tools predicted that miR-539 both targeted with the 3'-UTR of LINC00460 and MMP-9 mRNA, which was confirmed by luciferase reporter assay and western blot analysis. In summary, our study reveals that LINC00460 promotes MMP-9 expression through targeting miR-539, acting as an oncogenic RNA in the meningeoma malignancy and accelerating the proliferation and metastasis of meningeoma.
