1 Interestingly, the specific progesterone receptor antagonist RU486 induced UCP1 and UCP2 mRNAs, including UCP1 mRNA expression in non-NE-treated brown adipocytes, suggesting a profound effect of this antiprogestagen on brown adipocyte thermogenic capacity. Mifepristone uncoupling protein 1 Homo sapiens

3 Thus, are conclude that testosterone, 17-beta-estradiol, progesterone and RU486 have distinct actions on brown adipocytes, thus modulating UCP1 and UCP2 mRNA expression and/or lipid accumulation, and that sex hormones are factors that may explain in part the gender-dependent BAT thermogenic response. Mifepristone uncoupling protein 1 Homo sapiens
