The dual luciferase reporter gene assay (Figure 3E) showed that the luciferase activity of the wild type (WT) of USP30 untranslated region (3¢ UTR) significantly decreased when exposed to miR-137-5p mimic. However, there was no significant change in the luciferase activity of the mutant type (MUT) of ZC3H12B 3¢ UTR (p > 0.05).
