摘要：
Fibroblast growth factor 21 (FGF21) is a fasting-induced hepatokine that has potent pharmacologic effects in mice, which include improving insulin sensitivity and blunting growth. The single-transmembrane protein beta Klotho functions as a coreceptor for FGF21 in vitro. To determine if beta Klotho is required for FGF21 action in vivo, we generated whole-body and adipose tissue-selective beta Klotho-knockout mice. All of the effects of FGF21 on growth and metabolism were lost in whole-body beta Klotho-knockout mice. Selective elimination of beta Klotho in adipose tissue blocked the acute insulin-sensitizing effects of FGF21. Taken together, these data demonstrate that beta Klotho is essential for FGF21 activity and that beta Klotho in adipose tissue contributes to the beneficial metabolic actions of FGF21.
