Body and fat-pad weights of PparaFatKO and Pparafl/fl mice fed high-fat or normal-chow diets. Male (A) and female (B) PparaFatKO and Pparafl/fl mice were placed on high-fat (HFD) or normal-chow (NCD) diets for 30 weeks and body weights, total fat, inguinal white adipose tissue (iWAT), epididymal white adipose tissue (eWAT), and brown adipose tissue (BAT) were measured at the end of the study. ** p < 0.01, two-way ANOVA (vs. Pparafl/fl HFD) (± S.E.M.; male n = 11 NCD and n = 9 HFD, Pparafl/fl; female n = 13 NCD and n = 6 HFD, Pparafl/fl; male n = 13 NCD and n = 14 HFD, PparaHepKO; female n = 14 NCD and n = 6 HFD, PparaHepKO).
