We subsequently verified the targeted relationship between CCAT1 and miR-218-5p by dual-luciferase assay, which exhibited decreased luciferase activity in cells transfected with miR-218-5p mimic and CCAT1-WT while no significant difference was apparent in cells transfected with miR-218-5p mimic and CCAT1-MUT ( p < 0.01, Fig. 2E ).
