Somatostatin is a hormone and neuropeptide expressed in the pancreas, gastrointestinal tract, hypothalamus, and other tissues. It regulates directly the secretion of insulin, glucagon, many of the gastrointestinal hormones, and growth hormone. It is therefore surprising the somatostatin knockout (sst-ko) mice have a very mild phenotype. We subjected sst-ko mice and heterozygous siblings which served as controls to a high-calorie diet, and confirmed that sst-ko mice gain weight...

The gastric mucosa is a dynamic and regenerative tissue that functions in extreme conditions of low pH, mechanical insults and bacterial exposure. The mucosa is composed of pit and neck cells which secrete protective mucus, parietal and chief cells that secrete acid and digestive enzymes, enteroendocrine cells that affect motility, secretion and satiety, rare tuft cells, and at two stem-cell compartments. We studied the response of the gastric mucosa to sleeve gastrectomy surg...
