Application

Exendin-4 has been used as incretin mimetics for the treatment in HepG2 cells to exclude the influence of auxiliary material. It has also been used as an r (GLP-1R) agonist to exclude interference from auxiliary material.

Exendin-4 has been used for the treatment of ob/ob mouse model to determine the glucose and insulin concentrations and homeostasis model of assessment (HOMA), and for the determination of nuclear factor-?? (NF-?B) p65 level in macrophages treated with exendin-4.

Biochem/physiol Actions

Activates GLP-1 (glucagon-like peptide-1) receptors to increase intracellular cAMP in pancreatic acinar cells; has no effect on VIP receptors.

Exendin-4 mimics the activity of mammalian incretin hormone glucagon-like peptide 1 (GLP-1), and thus, functions in the control of glucose. This includes the secretion of insulin in a glucose dependent manner, negative regulation of high glucagon secretion, and increased duration of stomach emptying. In type 2 diabetes patients, this peptide can be administered subcutaneously for glycemic control, when metformin is unable to produce adequate results. It promotes the neogeneration and proliferation of ?-cells, and thus aids in the regeneration of pancreas. It acts as a ligand to exendin receptor, and leads to an elevation of acinar cell cAMP levels.

General description

Exendin-4 is an incretin mimetic peptide, which is composed of 39 amino acids. It is an analog of glucagon-like peptide 1 (GLP-1), and an insulinotropic agent, with a long half-life. Exendin-4 was historically isolated from the venom of Gila monster lizard called Heloderma suspectum.
