RBM24 and breast cancer: Furthermore, a luciferase reporter assay showed that miR-625-5p directly targeted the RBM24 3′UTR (Fig. 6d, e), and western blot analysis confirmed that RBM24 protein expression was reduced by miR-625-5p mimic transfection into BC cells compared to transfection with its antagomir (Fig. 6f).
