Fig. 6: SCEL is a direct target of miR-126.

a The predicted binding sites between miR-126 and SCEL 3′-UTR. A mutation was generated in 3′-UTR of SCEL in the complementary site for miR-126 binding. b Co-transfection of WT/MUT SCEL 3′-UTR and mimics NC/miR-126 mimics/inhibitor NC/miR-126 inhibitor in HEK293T cells. Firefly luciferase activity was examined by dual luciferase reporter assay. Renilla luciferase activity was used to normalize the activity of firefly luciferase. Data were representative images or were expressed as the mean ± SD of n = 3 experiments. c, d miR-126 and SCEL levels in HUVECs were determined by qRT-PCR. U6 or GAPDH served as an internal control. *P < 0.05, **P < 0.01.
