miR-9 directly targets E-cadherin. a – Bioinformatics prediction of the binding site of miR-9 with E-cadherin 3’UTR. b – The relative luciferase activity of E-cadherin wild-type (WT) or mutant (MUT) 3’UTR in HEK293 cells following transfection with miR-9 mimics. c – Relative expression of miR-9 in A549 cells transfected with miR-9 inhibitors. d – Relative expression of E-cadherin mRNA in A549 cells transfected with miR-9 inhibitors. *p < 0.01 vs. WT or NC
