abstractText | FGF21 is an atypical member of the FGF family that functions as a hormone to regulate carbohydrate and lipid metabolism. Here we demonstrate that the actions of FGF21 in mouse adipose tissue, but not in liver, are modulated by the nuclear receptor Rev-erbalpha, a potent transcriptional repressor. Interrogation of genes induced in the absence of Rev-erbalpha for Rev-erbalpha-binding sites identified betaKlotho, an essential coreceptor for FGF21, as a direct target gene of Rev-erbalpha in white adipose tissue but not liver. Rev-erbalpha ablation led to the robust elevated expression of betaKlotho. Consequently, the effects of FGF21 were markedly enhanced in the white adipose tissue of mice lacking Rev-erbalpha. A major Rev-erbalpha-controlled enhancer at the Klb locus was also bound by the adipocytic transcription factor peroxisome proliferator-activated receptor (PPAR) gamma, which regulates its activity in the opposite direction. These findings establish Rev-erbalpha as a specific modulator of FGF21 signaling in adipose tissue. |
