Proteins involved in metabolic regulation and in inflammation were measured in rats fed control diets without (Ctrl) or with (HFr) 10% (w/v) fructose in the water, or HFr diets supplemented with catechin (C), quercetin (Q) or both (CQ) (20 mg/Kg/d). Adiponectin, visfatin, MCP1, resistin, and TNFα protein levels were determined in epididymal adipose tissue. Bands were quantified and results were referred to β-actin as loading control, and expressed relative to control values. Data represent means ± SEM of 6 rats per group. Values having different superscripts are significantly different, p < 0.05, one way ANOVA test.
