BACKGROUND Helicobacter pylori-infection associated gastritis is known to be a significant risk factor of gastric cancer. Serum levels of Gastrin-17 and Pepsinogen1which are respectively biomarkers of gastric antral and corpus mucosal activity are well known parameters of atrophic gastritis. OBJECTIVES To determine the prevalence of Helicobacter pylori and atrophic gastritis amongst dyspeptic...

Gastrin plays a vital role in the development and progression of gastric cancer (GC). Its expression is up-regulated GC tissues several cell lines. Yet, underlying mechanism remains to be investigated. Here, we aim investigate gastrin proliferation. Gastrin-overexpressing model was constructed using SGC7901 cells. Then differentially expressed proteins were identified by iTRAQ analysis. Next, u...

The serum gastrin response to a standard protein meal has been determined in achlorhydric patients with atrophic gastritis and contrasted with the response in normal subjects whose gastric contents were kept continuously neutral by intragastric bicarbonate instillation. Five normal subjects showed a significant increase in serum gastrin from a mean (+/- SEM) of 17 +/- 3 pg/ml to 119 +/- 10 pg/m...

The objective of this study was to determine the effect of anti-gastrin antiserum in combination with varied dosages of cytotoxic drugs (5-Fluorouracil (5FU) + Cisplatin (CDDP)) in vivo growth of the human gastric cancer cell-line, SGC-7901, which expressed cholecystokininB/gastrin receptors and secreted gastrin. The anti-gastrin antiserum was obtained by immunizing rabbits using a novel immuno...

Minigastrin, a gastrin with 13 amino-acid residues, was recently isolated from tissues by Gregory and Tracy (1974). In this study, pure human natural nonsulphated minigastrin (HG-13-I) and pure human natural nonsulphated heptadecapeptide gastrin (HG-17-I) were compared with regard to acid-stimulating potency and rate of disappearance from blood. Three dogs with gastric fistulae and Heidenhain p...
