HFD increases UCP1 protein levels without changes in BAT mitochondrial content. Whole interscapular BAT lysates were subjected to Western Blot analysis. (A) UCP1 protein levels using β-actin as a loading control. (B) Relative mRNA expression of BAT markers Ucp1, Zic1, Prdm16, PGc1α, Bmp8b, Cidea, Dio2, Fgf21, Hif1α and Leptin in NCD and HFD-fed mice. (C) TIM44 protein levels using β-actin as a loading control. Shown representative immunoblots out of at least 4 independent experiments. (D) Mitochondrial dynamics were determined by the relative mRNA expression of Mfn1, Mfn2 and Opa1 of BAT in NCD and HFD-fed mice. Results are represented as mean ± SEM. n = 8–10; *p < 0.05.
