Progrp and gastrin

WebDec 1, 2011 · ProGRP is a precursor form of gastrin-releasing peptide (GRP) (or mammalian bombesin), which is a neuropeptide hormone originally isolated from porcine gastric tissue [9]. GRP is widely distributed throughout the gastrointestinal and pulmonary tract. GRP is produced by SCLC cells and could be helpful in the monitoring of patients [10]. WebGastrin-releasing peptide (GRP) is synthesized, stored, and secreted by enteric neurons in the stomach and intestines and acts locally via a neurocrine mode. Administration of GRP, …
