Fibroblast growth factor (FGF) 21 is a member of the FGF superfamily. It is most closely related to FGF19 and FGF23, sharing 30–35% amino acid sequence homology. The FGF19 subfamily comprises FGF19, FGF21, and FGF23, and all three FGF19 subfamily members have recently emerged as metabolic hormones involved in the regulation of glucose, lipid, bile acid, and phosphate metabolism[1]. FGF21 provides sustained glucose and lipid control, amelioration of insulin resistance, improvements in β-cell function and mass, and beneficial changes in other lipoprotein and cardiovascular risk factor profiles[2].
