miR-127-5p mimic blocks the AKT/NF-κB signaling pathway by targeting TRAF1. Protein expression levels were (A) determined by western blotting, and (B) the ratios of p-AKT/AKT and p-65/p65 were semi-quantified. **P<0.01, ***P<0.001 vs. the control group (miR-NC mimic + pcDNA3.1); #P<0.05 vs. the miR-127-5p mimic group; &P<0.05 vs. the LPS + miR-127-5p mimic group. LPS, lipopolysaccharide; miR, microRNA; p, phosphorylated; TRAF1, tumor necrosis factor receptor-associated factor 1.
