General description

[D-Lys3]-GHRP6 (growth hormone releasing peptide 6) is a synthetic analog of the orexigenic peptide hormone called ghrelin.

Application

[D-Lys3]-GHRP-6 has been used:
  • to study its role in incretin dysfunction and hyperglycemia in cystic fibrosis
  • as an antagonist of growth hormone secretagogue receptor (GHS-R)
  • as ghrelin receptor antagonist to study the dose-dependent effects of intraduodenal ghrelin on the glucose infusion rate (GIR) during pancreatic-euglycemic clamp procedure (PECs)

[D-Lys3]-GHRP6 has been used-
  • to treat bovine somatotropes to determine the release of GH from treated cells and non-treated or control cells
  • for intraperitoneal injection to groups of broiler chicken to determine the effect on feed intake, weight gain, and feed conversion ratio

Biochem/physiol Actions

[D-Lys3]-GHRP-6, a selective growth-hormone secretagogue receptor (GHSR) antagonist displays pro-autophagic effects on skeletal muscle. It can be used to study the dependency of GHSR-1a signalling mediated by acylated ghrelin.
[D-Lys3]-GHRP6 (growth hormone releasing peptide 6) induces the secretion of growth hormone (GH). In the membrane of clonal GC somatotropes, this peptide elevates the number of functional voltage-gated Ca2+ and Na+ channels. Chronic treatment with this peptide causes an elevation in Na+ macroscopic current in bovine pituitary somatotropes in culture, which results in an increase in the release of GH.

A variety of ion channels are expressed in the plasma membrane of somatotropes within the anterior pituitary gland. Modification of these channels is linked to intracellular Ca2+ levels and therefore to hormone secretion. Previous investigations have shown that the gut-derived

The synthetic hexapeptide, His-D-Trp-Ala-Trp-D-Phe-Lys-NH2 (GHRP, Growth Hormone-Releasing Peptide), has no structural similarities with any of the GH-releasing peptides known and its action in releasing GH is by a complementary but yet not clearly defined action on the pituitary as well
