Gliomas are the most common type of primary brain tumors. CircRNA ephrin type-B receptor 4 (circEPHB4) is a circular RNA derived from the receptor tyrosine kinase EPHB4. However, the clinical significance and the specific roles of circEPHB4 in gliomas and glioma cancer stem cells (CSCs) have not been studied. Here, we found that circEPHB4 (hsa_circ_0081519) and SOX10 were up-regulated, while miR-637 was down-regulated in glioma tissues and cell lines. Consistently, circEPHB4 was positively correlated with SOX10, but negatively correlated with miR-637. The altered expressions of these molecules were independently associated with overall survival of patients. CircEPHB4 up-regulated SOX10 and Nestin by directly sponging miR-637, thereby stimulating stemness, proliferation, and glycolysis of glioma cells. Functionally, silencing circEPHB4 or increasing miR-637 levels in glioma cells was sufficient to inhibit xenograft growth in vivo. In conclusion, the circEPHB4/miR-637/SOX10/Nestin axis plays a central role in controlling stem properties, self-renewal as well as glycolysis of glioma cells and predicts the overall survival of glioma patients. Targeting this axis might provide a therapeutic strategy for malignant gliomas.
