| In recent years, it has become clear that the islets secrete several more hormones, including gastrin and pancreatic polypeptide. |
| The molecule closely simulates the hormone gastrin, which is involved with hydrochloric acid secretion. |
| There was no tumoral expression for serotonin, glucagon, insulin, gastrin, vasointestinal peptide, or pancreatic polypeptide. |
| It produces excessive gastrin, resulting in disproportionate amounts of hydrochloric acid and pepsin leading to severe peptic ulcer disease. |
| Further work is needed to establish whether the homologous CCK and gastrin act as separate peptides in dogfish sharks. |
| The tumors secrete the hormone gastrin, which results in excess acid production and often peptic ulcer disease. |
