Application

Exendin Fragment 9-39 has been used to study its effect on basal microvascular permeability.It has also been used as a glucagon-like peptide-1 receptor (GLP-1R) antagonist:

  • to study to determine whether Ex-4 a GLP-1R agonist acts through GLP-1R, in mouse skeletal muscle cell line
  • to study its effects on the adaptation of islets in glucose-dependent insulinotropic polypeptide knockout mice
  • to study its in vivo effects on GLP-1 signaling on insulin response in mice

Biochem/physiol Actions

Exendin Fragment 9-39 is an antagonist of glucagon-like peptide-1 (GLP-1) receptor, and also acts as an inhibitor of the glucose-dependent insulinotropic polypeptide (GIP)-receptor binding. It also prevents the production of cAMP by GIP.GLP-1, along with GIP, acts as a physiological incretin.

Glucagon-like peptide-2 (GLP-2) has been suggested for the treatment of mucositis, but the peptide has also been shown to accentuate colonic dysplasia in carcinogen-treated mice. Recently, an effect on intestinal growth was discovered for glucagon-like peptide-1 (GLP-1), OBJECTIVE: To determine

Mice genetically deficient in the glucagon receptor (Gcgr(-/-)) show improved glucose tolerance, insulin sensitivity, and α-cell hyperplasia. In addition, Gcgr(-/-) mice do not develop diabetes after chemical destruction of β-cells. Since fibroblast growth factor 21 (FGF21) has insulin-independent glucose-lowering properties
