Correlations between body fat content and BAT thermogenic activity. A BAT mass; B mitochondria protein content; C cytochrome c oxidase activity, COX; D gene expression of uncoupling protein 1, ucp1, E serum T3 levels, and F serum T4 levels. Animals were exposed to 21, 10 and 0 °C for 14 days and transferred to a warm temperature at 30 °C on days 15–42. *, significant coefficients (P < 0.05), ***, P < 0.001
