Introduction
Asprosin is a fasting-induced glucogenic protein that responds to low dietary glucose by stimulating hepatic glucose release. It is
secreted by white adipose tissue and circulates in the plasma at nanomolar levels. Asprosin- induced hepatic glucose production is
mediated by G protein-cAMP-protein kinase A pathway and is shown to be pathologically related with human and mouse insulin
resistance.
