The effect of NLRX1 on MAVS-RLR-mediated downstream signaling pathways in HBV serum-treated HepG2-NTCP cells. The HepG2-NTCP cells were transfected with NLRX1-overexpressed plasmid or NLRX1 siRNA for 48 h, and then were treated with HBV serum for another 48 h prior further analysis. (A) Western blotting was used to analyze the protein level of p65, p-p65, IRF3, IRF7, p-IRF3, and p-IRF7. (B) The phosphorylation ratios of p65, IRF3, and IRF7 were analyzed on the basis of the gray value. (C) The effect of NLRX1 on the activity of IFN-α, IFN-β, and IL-6 promoters was calculated using a luciferase reporter assay. All experiments were independently repeated for three times. One-way ANOVA was applied for the comparison of three sets of data.
HBV: hepatitis B virus; ANOVA: analysis of variance.
*: P < 0.05; **: P < 0.01.
