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

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
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

The third intracellular loop domain of G protein-coupled receptors regulates their desensitization, internalization, and resensitization. Colorectal and pancreatic cancers, but not the nonmalignant tissue, express a splice variant of the cholecystokinin 2 receptor (CCK2R) called CCK(2i4sv)R that, because of intron
