A gastrinoma is a gastrin-secreting tumor that can occur in the pancreas, although it is most commonly found in the duodenum. Duodenal wall gastrinomas have been identified in 40-50% of patients.

Gastrinoma: A GASTRIN-secreting neuroendocrine tumor of the non-beta ISLET CELLS, the GASTRIN-SECRETING CELLS. This type of tumor is primarily located in the PANCREAS or the DUODENUM. Majority of gastrinomas are malignant. They metastasize to the LIVER; LYMPH NODES; and BONE but rarely elsewhere. The presence of gastrinoma is one of three requirements to be met for identification of ZOLLINGER-ELLISON SYNDROME, which sometimes occurs in families with MULTIPLE ENDOCRINE NEOPLASIA TYPE 1; (MEN 1).

Significant differences in responses to intraperitoneally injected tyramine or cold exposure (-10 degrees C) were observed in young (3-4 mo) male Sprague-Dawley (S-D) and Fischer 344 (F344) rats cold-acclimated (CA) or non-cold-acclimated (non-CA). Non-CA S-D and F344 rats respond to tyramine by increased O2 uptake and elevation of colonic temperature, but, as we had reported previously, the optimal doses of tyramine required was significantly different for these two strains, i.e., 2 mg/kg for F344 vs. 20 mg/kg for S-D. The response to tyramine was significantly potentiated by cold acclimation in both strains of rats. Despite the different dosages of tyramine given to the animals, similar increases in O2 uptakes and colonic temperatures were observed. Differences between these two strains were also evident in their responses to a cold challenge (3 h, -10 degrees C). The ranking for cold tolerance (-10 degrees C) was as follows: CA F344 greater than non-CA F344 greater than CA S-D greater than ...
At a Glance Clinical manifestations of Zollinger-Ellison syndrome (ZES), a syndrome caused by a gastrin-secreting neuroendocrine tumor (gastrinoma), result from high gastric acid output due to hypertrophy of parietal and histamine-secreting enterochromaffin-like (ECL) cells, as well as direct stimulation of parietal cells. More than 90% of patients develop peptic ulcers, but only a small number…. ...

Gastrin-Releasing Peptide: Neuropeptide and gut hormone that helps regulate GASTRIC ACID secretion and motor function. Once released from nerves in the antrum of the STOMACH, the neuropeptide stimulates release of GASTRIN from the GASTRIN-SECRETING CELLS.
Several stimuli directly act on G Cells to induce their release of gastrin. These include the local presence of protein and amino acids as well as physical expansion of the stomach by the presence of food. Additionally, release of GRP onto G Cells by efferents of the vagus nerve induces gastrin release ...

Q. Write Short Notes on Gastrin, CCK, and Secretin Gastrin Gastrin is produced by cells called G cells in the antral portion of the gastric mucosa. G cells are flasked shapes, with a broad base containing many gastric granules and a narrow apex that reaches the mucosal surface. Gastrin is typical of a number of […]. ...

acetylcholine (ACh; M3 receptor), and histamine (H2 receptor). Acid is secreted across the parietal cell canalicular membrane by the H+/K+ ATPase proton pump into the gastric lumen. The gastrin that is secreted by antral G cells in response to intraluminal dietary peptides acts directly on parietal cells and also stimulates release of histamine from enterochromaffin-like (ECL) cells. The vagus nerve stimulates postganglionic neurons of the enteric nervous system to release acetylcholine ACh, which acts on parietal and ECL cells. In the antrum, release of gastrin-releasing peptide (GRP) from postganglionic neurons directly increases gastrin release, whereas release of ACh indirectly increases gastrin secretion by inhibiting release of somatostatin from antral D ... ...

Gastrin is a peptide hormone that stimulates secretion of gastric acid by the parietal cells of the stomach. Gastrin binds to a G-protein coupled receptor encoded by the CCKBR gene that also binds cholecystokinin (CCK), a brain regulatory peptide. The receptor is therefore known as the gastrin/cholecystokinin type B receptor. It is also known as cholecystokinin B receptor, cholecystokinin-2 receptor, CCK-B, CCKB-R, CCKRB, CCK2R, and GASR. The gastrin/cholecystokinin receptor is expressed mostly in central nervous system and the gastrointestinal tract. A misspliced transcript variant of the CCKBR gene that includes an intron has been associated with colorectal and pancreatic tumors.. ...
