Description : Fibroblast Growth Factor-21 (FGF-21) is a metabolic cytokine belonging to the heparin-binding FGF family. Along with FGF-19/15 and FGF-23, FGF-21 is categorized as a member of the atypical FGF subfamily, as it must be complexed to the Klotho co-receptor in order to bind to the FGF receptors and activate the downstream signaling pathway. In vivo FGF-21 is expressed in liver, pancreas, adipose tissue, and skeletal muscle, and it plays a central role in the energy metabolism. The expression of FGF-21 is stimulated by free fatty acids and insulin resistant states and is correlated with whole-body insulin resistance. FGF-21 activates glucose uptake in adipocytes and increases insulin sensitivity, implicating it as a novel target with potential anti-diabetic properties.

Ask a question
How is FGF21 expression regulated in adipose tissue? 10/31/2022

FGF21 expression in adipose tissue is regulated by various factors, including peroxisome proliferator-activated receptor gamma (PPARγ) activation.

What are the effects of FGF21 on lipid metabolism? 08/27/2020

FGF21 influences lipid metabolism by promoting the utilization of fatty acids for energy, contributing to the regulation of lipid homeostasis.

Can FGF21 be a biomarker for metabolic health? 08/07/2019

FGF21 levels are being explored as potential biomarkers for metabolic health, reflecting conditions such as insulin resistance and metabolic syndrome.

Is FGF21 involved in the regulation of insulin sensitivity? 03/03/2019

Yes, FGF21 plays a role in improving insulin sensitivity, making it a potential target for interventions in insulin resistance-associated conditions.

Does FGF21 have roles in energy expenditure? 11/11/2018

Yes, FGF21 influences energy expenditure by promoting thermogenesis in brown adipose tissue, contributing to overall metabolic regulation.

Are there gender-specific differences in FGF21 levels? 08/30/2017

Gender-specific differences in FGF21 levels have been reported, with some studies suggesting higher circulating FGF21 concentrations in females.

What signaling pathways does FGF21 activate? 01/09/2016
