====== Long non-coding RNA in meningioma ====== The deepgoing role of [[Long non-coding RNA]] (lncRNAs) on [[meningioma]] is still unclear. Xing et al., investigated the roles of lncRNA [[LINC00460]] in meningioma tissue and uncover its molecular mechanism. Results revealed that LINC00460 expression level was significantly up-regulated in meningioma tissues and malignant meningioma 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. The study reveals that LINC00460 promotes MMP-9 expression through targeting miR-539, acting as an oncogenic RNA in the meningioma malignancy and accelerating the proliferation and metastasis of meningioma ((Xing H, Wang S, Li Q, Ma Y, Sun P.
