GIP and GLP-1 on Gastric Emptying, Appetite and Insulin-glucose

2014-08-27 03:15:30 | BioPortfolio


Academic phase 1 study which investigates the effects of the two incretin hormones glucose-insulinotropic peptide (GIP) and glucagon-like peptide-1 (GLP-1) on gastric emptying, appetite, insulin release and glucose disposal in the body. The hypothesis is that incretin hormones not only stimulate insulin release but also inhibits gastric emptying. This effect can be utilized for further drug development.


Effects of GIP and GLP-1 on gastric emptying, appetite control and insulin release in relation to glucose levels in the bloodstream. Infusions of GIP and GLP-1 are given under simultaneous gastric emptying study and appetite questionnaires and blood sampling for analysis of insulin, glucose, and other gut hormones such as glucagon, ghrelin, and PYY, as well as those administered, GIP and GLP-1.

Medical and Biotech [MESH] Definitions

A peptide of 36 or 37 amino acids that is derived from PROGLUCAGON and mainly produced by the INTESTINAL L CELLS. GLP-1(1-37 or 1-36) is further N-terminally truncated resulting in GLP-1(7-37) or GLP-1-(7-36) which can be amidated. These GLP-1 peptides are known to enhance glucose-dependent INSULIN release, suppress GLUCAGON release and gastric emptying, lower BLOOD GLUCOSE, and reduce food intake.

A pyrazine-derived DIPEPTIDYL-PEPTIDASE IV INHIBITOR and HYPOGLYCEMIC AGENT that increases the levels of the INCRETIN hormones GLUCAGON-LIKE PEPTIDE-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP). It is used in the treatment of TYPE 2 DIABETES.

A receptor for GLUCAGON-LIKE PEPTIDE 2 (GLP-2) that is expressed on the surface of intestinal cells as well as neural cells. GLP-2 and other peptides act through GLP-2R to regulate cellular responses to BLOOD GLUCOSE, INFLAMMATION, and FOOD INTAKE.

A receptor for GLUCAGON-LIKE PEPTIDE 1 (GLP-1) expressed primarily on the surface of beta and ductal exocrine cells of the pancreas, as well as cells of other tissues. GLP-1 acts through GLP-1R to potentiate signaling in pancreatic cells in response to glucose-stimulated insulin secretion (GSIS).

Peptides derived from proglucagon which is also the precursor of pancreatic GLUCAGON. Despite expression of proglucagon in multiple tissues, the major production site of glucagon-like peptides (GLPs) is the INTESTINAL L CELLS. GLPs include glucagon-like peptide 1, glucagon-like peptide 2, and the various truncated forms.
