The biological functions of long noncoding RNAs (lncRNAs) in the glioma have gained much attention in recent researches. However, the deepgoing mechanism by which lncRNA regulates the gliomagenesis is still ambiguous. In this work, we found that lncRNA CASC11 was significantly up-regulated in the glioma specimens and cells, and the ectopic overexpression indicated the poor prognosis of glioma patients. CASC11 expression could be activated by the transcription factor SP1. In vivo and vitro, the knockdown of CASC11 impaired the proliferation, migration and tumor growth of glioma cells. In mechanical experiments, the miR-498 was found to target the 3'-UTR of lncRNA CASC11 and FOXK1 mRNA. Taken together, the data suggest the regulation of SP1/ CASC11/miR-498/FOXK1 in the gliomagenesis, which might provide a potential therapeutic strategy for glioma.
