| Description | FGF-21 is an atypical member of the FGF superfamily and functions as an endocrine hormone. It is mainly secreted by the liver but also by other tissues including adipocytes, pancreas, and skeletal muscle. It can act not only locally but also can travel through the circulatory system and function as an endocrine hormone. FGF-21 signals through a complex formed by classic FGF receptors and the coreceptor β-Klotho. Although it has been shown that FGF-21 can bind all FGFR isotypes, in vitro studies have shown that FGF-21 prefers FGFR1c/β-Klotho complex. Since the expression of β-Klotho is restricted to several tissues including liver, adipose tissues, pancreas, CNS and testes, it is believed that these tissues are the major sites of FGF-21 action. In liver, FGF-21 can induce gluconeogenesis, fatty acid oxidation, triglyceride degradation, and ketogenesis. It has also been reported that PGC-1α, a key regulator of mitochondrial energy metabolism, can be induced by FGF-21. In adipose tissue, FGF-21 regulates lipolysis and stimulates glucose uptake independent of insulin. In pancreatic islets, FGF-21 can increase insulin expression. Transgenic mice overexpressing FGF-21 are protected from diet-induced obesity; therefore, FGF-21 has been considered a promising potential therapy for the treatment of obesity-related disorders. FGF-21 can cross the blood-brain barrier and FGF-21 has been shown to regulate peripheral metabolism and circadian behavior by acting on the nervous system. |
