摘要
The brain-gut hormones, cholecystokinin (CCK) and gastrin, regulate the growth of gastrointestinal mucosa and tumor cells. In this study, reverse transcription-polymerase chain reaction (RT-PCR) was used to evaluate messenger RNA expression for CCK, gastrin, CCK-A receptor, and CCK-B/gastrin receptor in surgical specimens of gastric cancers and in normal antrum and body mucosa of the stomach. The CCK mRNA expression was detectable in 4/14 (29%) samples of gastric cancer and in 3/12 (25%)samples of antral mucosa. However, the gastrin mRNA expression was not detectable in any gastric cancer samples, although it was detectable in all the samples of antral mucosa. The CCK-A receptor mRNA expression was detectable in 5/14 (36%) samples of gastric cancer and in 7/12 (58%) body mucosa. Three cases out of 14 (21%) of gastric cancer expressed both CCK gene and CCK-A receptor gene-The CCK-B receptor mRNA expression was detectable in only 1/14 (7%) samples of gastric cancer, although it was detectable in 10/12 (83%) body mucosa of the stomach. These findings may suggest a greater role for CCK and CCK-A receptor than for gastrin and CCK-B receptor in gastric cancers.
