Upregulation of circZNF652 reversed the inhibitory effects of miR-486-5p on GBM cell growth, migration, invasion, and EMT process. (a) and (b) Cell viability was examined using CCK-8 assay after A172 and U87 cells were transferred with NC mimic, miR-486-5p mimic, miR-486-5p mimic+pcDNA3.1, miR-486-5p mimic+pcDNA-SERPINE1. (c) and (d) The colony formation number was measured using colony formation assay after A172 and U87 cells were transferred with NC mimic, miR-486-5p mimic, miR-486-5p mimic+pcDNA3.1, miR-486-5p mimic+pcDNA-SERPINE1. (e)-(h) Cell migration and invasion were determined using wound healing assay and transwell assay after A172 and U87 cells were transferred with NC mimic, miR-486-5p mimic, miR-486-5p mimic+pcDNA3.1, miR-486-5p mimic+pcDNA-SERPINE1. (i)-(l) The protein level of E-cadherin, N-cadherin, vimentin was detected using Western blotting after A172 and U87 cells were transferred with NC mimic, miR-486-5p mimic, miR-486-5p mimic+pcDNA3.1, miR-486-5p mimic+pcDNA-SERPINE1. **P < 0.01, ***P < 0.001.
