gastrin-releasing peptide, human

Gastrin-Releasing Peptide, human is a regulatory human peptide that elicits gastrin release and regulates gastric acid secretion and enteric motor function. The post-ganglionic fibers of the vagus nerve that innervate the G cells of the stomach release GRP, which stimulates the G cells to release gastrin.

Gastrin-Releasing Peptide, human(TFA) is a regulatory human peptide that elicits gastrin release and regulates gastric acid secretion and enteric motor function. The post-ganglionic fibers of the vagus nerve that innervate the G cells of the stomach release GRP, which stimulates the G cells to release gastrin.

Gastrin-releasing peptide (GRP) is a neuropeptide that stimulates gastrin release. It binds to (Ki = 300 nM) and stimulates amylase secretion in rat pancreatic AR42J cells (EC50 = 0.3 nM). GRP increases proliferation of human liver carcinoma HepG2 and MHCC97H cells but does not affect the proliferation of normal HL-7702 liver cells at a concentration of 1 nM. In vivo, GRP (0.35 nmol/kg/h) increases both pancreatic exocrine secretion and pancreatic polypeptide (PP) release in rats. It dose-dependently stimulates gastrin, pancreatic amylase, lipase, bilirubin, and acid output and induces gallbladder contraction in humans when administered at doses ranging from 1 to 27 pmol/kg per hour.

PACAP (1-38) free acid is a deamidated PACAP (1-38) derived from humans, sheep, and rats. PACAP (1-38) free acid can activate the human PAC1 receptor and promote cyclic adenosine monophosphate synthesis in NS‑1 neuroendocrine cells and non-neuroendocrine HEK293 cells.

Biotin-Gastrin Releasing Peptide, human, is a biotinylated derivative of gastrin-releasing peptide (GRP), a neuropeptide known for its growth-stimulatory and tumorigenic properties [1].

PACAP (1-38), human, ovine, rat TFA is an endogenous neuropeptide and a high-affinity agonist for the PAC1 receptor. This 38-amino acid peptide binds to the PAC1 receptor to activate adenylate cyclase, inducing an increase in intracellular cAMP levels and triggering downstream signaling. Research demonstrates that C-terminal amidation of PACAP (1-38), human, ovine, rat TFA is dispensable for its biological activity at the PAC1 receptor, with the non-amidated form retaining full agonistic potency. It plays crucial roles in neuroprotection, regulation of insulin secretion, and vasodilation.
