Clinical Utility

Pancreastatin is a 49 amino acid peptide produced by degradation of chromogranin A. It inhibits chromogranin A and parathyroid hormone release. Pancreastatin also inhibits release of somatostatin upon glucose stimulation. It may also control carbohydrate metabolism and hyperglycemia. Pancreastatin reduces the early phase of glucose induced insulin release. Suppression of insulin release upon glucose stimulation is a characteristic feature of Type-2 diabetes. Pancreastatin could play an important therapeutic role in the treatment of diabetes. Pancreastatin also inhibits the release of somatostatin. It may also control carbohydrate metabolism and hyperglycemia.
