Glucagon receptor levels, glucagon-stimulated and other forms of adenylyl cyclase activity, and regulatory component activity of adenylyl cyclase were determined in hepatic plasma membranes of rats administered streptozotocin without and with insulin to produce varying degrees of hyperglycemia.

The glucagon-receptor antagonist also suppressed the potentiation of glucose-induced insulin release by addition of 10 nmol/l glucagon.

In mice, genetic deletion of the glucagon receptor (Gcgr) results in increased levels of the insulinotropic hormone glucagon-like peptide 1 (GLP-1), which may contribute to the alterations in glucose homeostasis observed in Gcgr-/- mice.

Although Gcgr-/-Glp1r-/- islets exhibited increased sensitivity to the incretin glucose-dependent insulinotropic polypeptide (GIP), mice lacking both Glp1r and the GIP receptor (Gipr) maintained preservation of the enteroinsular axis following reduction of Gcgr signaling.

Finally, glucagon has a key role in promoting the catabolic consequences associated with states of deficient insulin action, which supports the therapeutic potential in developing glucagon receptor antagonists or inhibitors of glucagon secretion.

As both Pcsk2(-/-) and Gcgr(-/-) mice exhibit increased production of glucagon-like peptide-1 (GLP-1), which is absent in Gcg(gfp/gfp), GLP-1 is the likely cause of the difference in metabolic impact of glucagon deficiency in these animal models.
