glucagon , human

Glucagon is a 29-amino-acid peptide hormone liberated in the alpha cells of the islets of Langerhans. Glucagon-producing alpha cells represent one of the earliest populations of detectable islet cells in the developing endocrine pancreas.

Glucagon 对蛋白质和氨基酸的代谢产生显著的调节作用。它抑制了氨基酸与肝脏、肌肉以及胰腺蛋白的结合，增加氮的排出，并促进肝脏内尿素的合成。同时，Glucagon 增加了肝脏中转氨酶和尿素循环酶的浓度，提高了肝脏对氨基酸的摄取，并加强了氨基酸与肝糖原之间的结合，从而降低了血液中的氨基酸浓度。

Skyrin is a fungal metabolite characterized by a bisanthraquinone structure. It interferes with glucagon signaling through adenylate cyclase without binding to the glucagon receptor. At 10 μM, skyrin reduces both glucagon-stimulated cAMP production and glycogenolysis. It does not interfere with epinephrine or glucagon-like peptide 1 effects on these parameters.[1] Reference：[1].

It binds to PACAP receptors on SH-SY5Y and SK-N-MC human neuroblastoma and T47D human breast cancer cells (IC50s = 24.5, 106, and 105 nM, respectively) and inhibits cAMP accumulation induced by PACAP (1-38) (Kis = 457, 102, and 283 nM, respectively, in SH-SY5Y, SK-N-MC, and T47D cells). In vivo, in newborn pigs, PACAP (6-27) (10 μM) inhibits vasodilation of pial arterioles induced by PACAP (1-27) and PACAP (1-38) . It also inhibits PACAP (1-27)-stimulated increases in plasma insulin and glucagon levels and pancreatic venous blood flow in dogs when administered locally to the pancreas at a dose of 500 μg.
