title: Protein synthesis in human gastric mucosa: effects of pentagastrin, secretin, and 13-nle-motilin.
abstract: This study in man (n = 35) deals with the effects of in vivo administration of pentagastrin, synthetic secretin, and 13-norleucine-motilin (13-nle-motillin), respectively, on the in vitro incorporation of 14C-leucine into gastric mucosal protein. From the results presented it may be concluded that pentagastrin has a trophic influence on gastric mucosa in man, too, while protein synthesis in human duodenal mucosa remains unaltered. As the incorporatin of 14C-leucine into gastric mucosal protein is inhibited both by secretion and 13-nle-motiln, it may be hypothesised that secretin and motilin act as functional antagonists of gastrin in the regulation of human gastric mucosal protein synthesis.
