Effect of miR-199a-3p overexpression on the expression of proteins in the phosphatidylinositol 3-kinase/AKT/NF-κB signaling pathway. Western blotting was used to measure p110α and p85 protein expression relative to GAPDH; and the ratio of p-AKT over AKT and NF-κB protein expression relative to histone H. *P<0.05 vs. NC. NC, negative control; miR, microRNA; AKT, protein kinase B; NF-κB, nuclear factor-κB; p110α, catalytic subunit; p85, regulatory subunit; p, phosphorylated.
