We investigated the structural requirements for bombesin (BB)-like peptides to stimulate amylase secretion in rat pancreatic acini and examined the responsible intracellular signal transduction pathways. The tetradecapeptide BB-(1-14) was a full agonist, whereas the heptapeptide BB-(8-14) did not evoke amylase secretion. The mammalian BB analog neuromedin C decapeptide [NMC-(5-14)] was as poten...
