Verification of miR-1246 target genes. (A-C) The expression levels of miR-1246, miR-126, miR-142-3p, and miR-142-5p (A) and early B cell factor 1 (EBF1) protein (B, C) were analyzed after transfection with miR-1246 inhibitor or inhibitor control. (D-F) The expression levels of miR-1246, miR-126, miR-142-3p, miR-142-5p (D), and EBF1 protein (E, F) were analyzed after transfection with the miR-1246 mimic or mimic control. Bars show the mean ± SD results in three healthy donors or three patients with active SLE. All experiments were performed in triplicate. The Western blot image is a representative image (n = 3). (G) Schematic representation of the EBF1 luciferase reporter construct is shown. The sequence of the miR-1246 binding site in the 3′-untranslated region (3′-UTR) of EBF1 (gray box) is shown on the left. Mutated residues are shown in red. (H) Relative firefly luciferase activity in Jurkat cells co-transfected with an empty vector (mimic control) or an miR-1246 mimic, together with luciferase reporter constructs containing either a wild-type (WT) or a mutated (Mut) EBF1 3′-UTR are shown. Values in (H) are the mean ± SD results from three independent experiments. (**P < 0.01).
