Fig. 3. Dietary quercetin increases uncoupling protein 1 (UCP1) expression in brown adipose tissue (BAT). C57BL/6 mice were fed a high-fat diet (HFD) without or with 0.05% quercetin (HFD or HFD+Que) for 9 weeks. (A) Sections obtained from BAT were stained with H&E and an anti-UCP1 antibody. Original magnification, ×200. The arrows indicate increased UCP1 staining. (B) A representative Western blot showing protein expression of UCP1 in BAT. Results are mean±standard error of the mean (n=6 mice per group). *P<0.05 compared with control.
