Fibroblast Growth Factor 21 (FGF21)

Target
FGF21
Molecular classification
Fibroblast Growth Factor family, Endocrine hormone, Hepatokine
01

Overview

Fibroblast growth factor 21 (FGF21) is an atypical member of the fibroblast growth factor family, functioning primarily as an endocrine hormone. It is mainly secreted by the liver and plays a crucial role in regulating glucose and lipid metabolism, enhancing insulin sensitivity, and modulating energy expenditure. Elevated levels are observed in metabolic disorders like obesity and type 2 diabetes, making it a promising therapeutic target for these conditions.
