BAT from obese mice showed increased ROS generation with a concomitant increase in antioxidant enzyme activity. Oxidative status in interscapular BAT (left), eWAT (middle) and iWAT (right) from NCD and HFD mice was assessed by determining ROS generation, oxidative damage to lipids, and antioxidant enzymes activity. (A) Total ROS were measured by determining the fluorescent probe DCFH-DA oxidation (DCF RFU: Dichlorofluorescein Relative Fluorescence Units). (B) Combined detection of malondialdehyde and 4-hydroxynonenal as major lipid peroxidation by-products, expressed together as lipoperoxides (LPO). (CE) Antioxidant activity of the enzymes catalase (CAT) (C), superoxide dismutase (SOD) (D) and glutathione peroxidase (E). Results are represented as mean ± SEM. n = 8–10; *p < 0.05; **p < 0.01.
