miR-127-5p targets TRAF 3'-UTR. (A) miR-127-5p targets the 2,118-2,124 position of TRAF 3'-UTR. (B) miR-127-5p expression levels were significantly increased in the miR-127-5p mimic group compared with the miR-NC mimic group. (C) Luciferase activity was significantly decreased in the miR-126-5p mimic group compared with the miR-NC mimic group in Ana-1 murine macrophages transfected with TRAF1-WT-3'UTR. **P<0.01 vs. the miR-NC mimic group. 3'-UTR, 3'-untranslated region; miR, microRNA; NC, negative control; TRAF1, tumor necrosis factor receptor-associated factor 1; WT, wild-type; MUT, mutant.
