Disease relevance of Gastrin-Secreting Cells

  • Our data suggest that neither G-cell hyperplasia nor alterations in somatostatin release explain postvagotomy hypergastrinemia in the dog [1].
  • Effect of Helicobacter pylori products and recombinant cytokines on gastrin release from cultured canine G cells [2].
  • It was found that, although eradication of the H. pylori infection results in a dramatic reduction in stimulated gastrin secretion, it is not associated with a change in the numbers of antral G cells or D cells in patients with duodenal ulcer [3].
  • Certain cytokines released in H. pylori gastritis, such as tumor necrosis factor alpha and specific products of H. pylori, such as ammonia, release gastrin from G cells and might be responsible [4].
  • Intragastric balloons causing gastric hypertrophy, G-cell hyperplasia, and raised serum gastrin levels in rats [5].
 

High impact information on Gastrin-Secreting Cells

  • Percutaneous transhepatic venous sampling of gastrin: value in sporadic and familial islet-cell tumors and G-cell hyperfunction [6].
  • Gastric acid exerts a feedback inhibition on the secretion of gastrin from antral G cells [7].
  • The aim of this study was to examine whether the cytokines tumor necrosis factor alpha or interleukin 8 (IL-8), which are produced in the gastric mucosa of patients with H. pylori-induced peptic disease or H. pylori products, can stimulate gastrin release from isolated cultured canine G cells [2].
  • CONCLUSIONS: IL-8 stimulated gastrin release from isolated G cells, and the effect was potentiated by H. pylori products [2].
  • We speculate that G cells express type I IL-1 receptors and TNF P55 but not TNF P75 receptors [8].

Associations of Gastrin-Secreting Cells with chemical compounds

  • Gastrin release from the antral gastrin-expressing cell (G cell) is regulated by bombesin and luminal factors [14].
  • CONCLUSIONS: This is the first direct demonstration of GABA in gastrointestinal G cells [19].
  • CONCLUSIONS: The effects of capsaicin-induced changes in antral D- and G-cell secretion and acetylcholine discharge are due primarily to release of CGRP [24].
  • After PGE2 administration, no evidence of mucosal inflammation or atypia was observed, nor was there any evidence of ultrastructural changes in the overall appearance of the parietal and gastrin cells [25].
  • Chronic exogenous high dose adrenal cortical steroid administration to dogs resulted in a 137% increase in G-cell mass with an associated enhancement of peak serum gastrin levels [26].
 

Gene context of Gastrin-Secreting Cells

  • Bombesin dose-dependently increased gastrin secretion; this stimulatory effect on the G cell was significantly reduced after a 72-h starvation [27].
  • In a functional assay, using the fluorescent multidrug resistance protein 1 substrate 5-carboxyfluorescein, an increased efflux activity of HT29(col) cells was measured, as compared to the wild-type HT29 G(+) cells [28].
  • In normal tissues, VEGF immunoreactivity was detected in G cells and PP cells [29].
  • Conversely, duodenal G-cells process progastrin to gastrin tetratriacontapeptide (G34-NH(2)) with little processing at Lys(74)Lys(75) [30].
  • CONCLUSIONS: These data suggest that RUNX3 may play a physiologic role in chief cells and G cells in gastric mucosa, and that suppression of RUNX3 expression in intestinal metaplasia and carcinoma of human stomach may be implicated in gastric carcinogenesis [31].
