LncRNAs GAS5, NEAT1, GACAT3, CASC9, HMMR‐AS1, LINC00152, HOTAIRM1, AC003092.1, HOXD‐AS1, OIP5‐AS1, DANCR and so on have been reported to play oncogenic or tumour suppressive roles in glioma.32, 33, 41, 42, 43, 44, 45, 46, 47, 48, 49 Our study further proved the critical roles of lncRNAs in glioma and provided another candidate lncRNA for glioma prognosis and therapy. Here, PTGDR is linked to neoplasm.
