Glioma is a common invasive cancer with unfavorable prognosis in patients. Long non-coding RNAs have been reported to participate in modulating diverse cellular processes. Here, we focused on exploring the role of long intergenic non-protein coding RNA 1410 (LINC01410) in glioma and its underlying mechanism. The expression levels and protein levels of genes were analyzed by quantitative real-time PCR (RT-qPCR) analysis and western blot. Loss-of-function assays were performed to assess the function of LINC01410 in glioma cells. The interactions among MYC, LINC01410, microRNA-506-3p (miR-506-3p) and notch receptor 2 (NOTCH2) were validated through Chromatin immunoprecipitation (ChIP), RNA Binding Protein immunoprecipitation (RIP), RNA pull-down and luciferase reporter assays. Our data supported that LINC01410 was up-regulated in glioma cells. Bioinformatics predictions and the integrated experiments identified that MYC activated LINC01410 transcription and LINC01410 promoted the levels of NOTCH2 through sponging miR-506-3p and further motivated Notch signaling pathway. Rescue assays validated that LINC01410 exerted its influential functions on glioma cell proliferation and apoptosis via enhancing NOTCH2 expression. Our studies identified that LINC01410 accelerates the progression of glioma through acting as a ceRNA for miR-506-3p and elevating NOTCH2 expression to further activate the Notch signaling pathway, which indicated that LINC01410 might act as a novel regulator of glioma progression.
