. 1997 Jan;
112(1):136-43.
PMID: 8978352
Background & Aims: Helicobacter pylori infection in patients who have peptic ulcer disease is associated with altered regulation of gastric secretion, hypergastrinemia, and diminished somatostatin expression in gastric mucosa. Tumor...

PMID: 8997255
H(+)-K(+)-adenosinetriphosphatase (H(+)-K(+)-ATPase) is the principal enzyme responsible for the process of gastric acid secretion. This enzyme is expressed in a cell-type-specific manner in gastric parietal cells. To explore the mechanisms...

PMID: 8897880
Previously, we demonstrated that a single histamine H2 receptor can couple to both the adenosine 3',5'-cyclic monophosphate and inositol 1,4,5-trisphosphate/intracellular Ca2+ signaling pathways in a stimulatory manner. We undertook the...

PMID: 8864424
There is evidence that gastric Helicobacter pylori (Hp) infection promotes duodenal ulceration by releasing gastrin. We therefore asked how Hp releases gastrin. Tumour necrosis factor alpha (TNF-alpha) is up-regulated in...
