Female peri-ovarian WAT displays a higher browning propensity than male epididymal WAT. A. Bioluminescence quantification of lysates generated from iBAT, iWAT, skeletal muscle, and peri-gonadal WAT derived from 5-weeks-old male and female KI mice. Luminescence was normalized to corresponding protein concentrations, n = 6. Data were analyzed with unpaired t test, *P < 0.05 (Mean ± SD). B. Gene expression analysis of male epididymal and female peri-ovarian WAT of KI mice, n = 6. Data were analyzed with Two-way-ANOVA, *P < 0.05, **P < 0.01, ***P < 0.001 (Mean ± SD). C. Representative hematoxylin and eosin staining of epididymal and peri-ovarian WAT; black arrows indicate the multilocular adipocytes, n = 6.
