Effect of HFD and AuNP treatment on pro-inflammatory markers in abdominal fat and liver. mRNA expression of F4/80 (a, d), TNFα (b, e), and TLR-4 (c, f) in Chow, OB, OB-EAu, OB-LAu and OB-HAu mice at 15 weeks. Results are expressed as mean ± S.E.M. Data were analyzed by one-way ANOVA followed by post hoc Bonferroni test; *P < 0.05, **P < 0.01 vs Chow; ^†P < 0.05, ^††P < 0.01 vs OB. Data analyzed with conditional student t test followed by Welch correction, τ P < 0.05 vs Chow; n = 5–8
