title: A possible physiological function of pancreatic pro-colipase activation peptide in appetite regulation.
abstract: Pancreatic pro-colipase activation peptide, a pentapeptide with the sequence VPDPR was found to significantly suppress food intake of 20 h fasted Sprague-Dawley rats in a dose-dependent way. A rat treated with pro-colipase-enriched pellets for 26 days showed decreased daily food intake and retarded growth, which were restored during a following period of regular feeding. Genetically obese Zucker rats (fa/fa) were found to contain a reduced content of pancreatic pro-colipase (60% reduction), whereas the pancreatic lipase content was normal. A physiological function of pancreatic pro-colipase activation peptide as an endogenous satiety signal is suggested.
