YM022 is a very potent, selective antagonist of the gastrin/cholecystokinin (CCK)-B receptor. The Ki value for CCKB is 68 pM vs 63 nM for CCKA. In rats, YM022 inhibits pentagastrin-induced gastric emptying with an ED50 or 7.8 nM/kg.

Capsaicin has beneficial pharmacological properties, such as the ability to improve appetite and digestion. However, capsaicin has been reported to suppress gastric acid output, but to increase secretion; no consensus as to its effects on gastric acid output has been
Gastrin-recognizing CCK2 receptors are expressed in parietal cells and in so-called ECL cells in the acid-producing part of the stomach. ECL cells are endocrine/paracrine cells that produce and store histamine and chromogranin A (CGA)-derived peptides, such as pancreastatin. The ECL

Cyclooxygenase (COX)-2 has been causally implicated in carcinogenesis. The evidence for increased COX-2 in the malignant progression of Barrett's esophagus is contradictory. We hypothesize that COX-2 expression may be causally affected by the gastrin status via the cholecystokinin 2 (CCK(2))

The gastric cholecystokinin-B/gastrin receptor (CCK-BR) is a key regulator of enterochromaffin-like cell function and proliferation. Over the last decade, a number of small non-peptide CCK-BR "antagonists" have been discovered. Here, we demonstrate that some of these non-peptide ligands in fact
In the present study, we investigated whether cholecystokinin (CCK) or its structurally related peptide gastrin participates in long term regulation of adipocyte leptin secretion. The levels of circulating leptin observed after 2 and 6 h of refeeding in 18-h fast
