Cellular and Molecular Targets of Gastrinisolated and characterized by Gregory and Tracy (.) in 1961, and since then became a subject of intensive study. It is one of the most well studied peptide hormones (.). Nevertheless, in spite of an enormous amount of research that was already conducted on gastrin, it might be just a beginning of an

Within the GI tract, these responses, such as slowing of gastric emptying, gallbladder emptying, pancreatic exocrine secretion, and inhibition of gastric acid secret

Effects of Aging on Gut Hormonese. In 1987, 29 6 million Americans, or 12% of the population, were 64 yr of age or older. The number of elderly will likely increase, and by 2050, demographers estimate that nearly one-fifth (20%) of Americans will be at least 65 yr of age .. It is projected that people at age 75 will live at least

Intraluminal Regulatory Peptides and Intestinal Cholecystokinin Secretioness in understanding how CCK secretion is regulated is apparent when one compares what is known about the regulation of gastrin secretion with that established for CCK .. This is more remarkable because gastrin, which is phylogenetically CCK’s younger sibling ., was purified and sequenced from porci

Neuroendocrine Regulation of Intestinal Peristalsis insures that digestion and absorption of nutrients is complete, and that unabsorbable residue is expelled. The process responsible for postprandial propulsion is a propagated reflex, the peristaltic reflex. This reflex can be initiated by distension (i.e., radial muscle stretch) of the gut wall or
