miR-137-3p directly targets JNK3. (A) miR-137-3p-binding sites located on the 3ʹUTR of JNK3 mRNA and the wild-type or mutant site of JNK3 3ʹUTR were cloned into the pmirGLO plasmid. (B) and (C) miR-137-3p mimics or scramble control and wild-type or mutant JNK3 3ʹUTR were cotransfected into PC-3 or DU145 cells. miR-137-3p reduced luciferase activities in prostate cancer cells transfected with the wild-type 3ʹUTR but did not alter luciferase activities in cells transfected with the mutant JNK3 3ʹUTR. (D) Western blotting was performed after transfecting cells with miR-137-3p mimics or control, and (E) JNK3 protein levels were detected in xenograft samples. **p<0.01 compared to the corresponding controls.
