Abstract
A peptide hormone has been isolated from porcine intestine. Its primary structure was found to consist of 36 amino acid residues in a sequence identical to that of the porcine pancreatic polypeptide, previously not isolated from intestines or a tissue other than pancreas. The gut polypeptide significantly suppresses glucose-induced insulin secretion in vitro. Using an immunohistochemical technique, we also identified cells in the porcine gastrointestinal tract that were immunoreactive with pancreatic polypeptide. The immunoreactivity disappeared after absorption with the isolated gut polypeptide or synthetic human pancreatic polypeptideKeywords
