Some mice were daily injected mouse recombinant FGF21 (rFGF21, purchased from Creative BioMart, Shirley, NY, USA) subcutaneously at 0.25 mg/kg body weight.. The mice were fasted for 6 h and then sacrificed by cervical dislocation after blood was collected via the retro-orbital venous sinus under anesthesia by inhalation of isoflurane.The mice were fasted for 6 h and then sacrificed by cervical dislocation after blood was collected via the retro-orbital venous sinus under anesthesia by inhalation of isoflurane.

Q&As

How is FGF21 expression regulated in adipose tissue?

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?

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?

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?

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?

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?

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?

FGF21 activates signaling pathways such as the AMP-activated protein kinase (AMPK) pathway, which contributes to its metabolic effects.
