What is PANCREATIC POLYPEPTIDE (BOVINE)?

Biological Activity

Pancreatic Polypeptide, bovine is a linear polypeptide of 36 amino acids produced in the pancreas that inhibits pancreatic secretion induced by secretin and cholecystokinin. It is a neuropeptide (NPY) receptor agonist with high affinity for NPYR4.

in vitro

Pancreatic Polypeptide, bovine is an agonist of NPY receptor, with high affinity at NPYR4. Pancreatic Polypeptide (1 μM) does not alter proliferation in BRIN BD11 or 1.1B4 beta-cells, but reverses the decreased cell viability in BRIN BD11 cells induced by streptozotocin. Pancreatic Polypeptide (0.1 nM-1 μM) shows no effect on insulin secretion from isolated mouse islets, and does not affect the membrane potential and (Ca ²⁺ ) _i levels in BRIN BD11 cells at 1 μM. Pancreatic Polypeptide, bovine inhibits secretin- and cholecystokinin-stimulated pancreatic secretion. ¹²⁵ I-Pancreatic Polypeptide, bovine shows no specific binding to pancreatic acini.

in vivo

Pancreatic Polypeptide (25 nmol/kg bw, ip) reduces glucose-stimulated insulin concentrations but shows no effect on acute feeding behaviour in overnight fasted mice. Pancreatic Polypeptide, bovine (BPP; 40 μg/kg) inhibits CCK -33-induced pancreatic protein output during the entire bovine Pancreatic Polypeptide infusion period, but shows no effect on biliary protein output during CCK-33 or CCK-8 infusion.
