耗材描述
Pancreatic Polypeptide, bovine
产品活性:Pancreatic Polypeptide, bovine 是由 36 个氨基酸组成的直链多肽,由胰腺中产生,能够抑制由分泌素和胆囊素诱导的胰腺分泌。Pancreatic Polypeptide, bovine 是神经肽 (NPY) 受体激动剂,对 NPYR4 有很高的亲和性。

研究领域:GPCR/G Protein | Neuronal Signaling
作用靶点:Neuropeptide Y Receptor
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 (Ca2+)i levels in BRIN BD11 cells at 1 μM. Pancreatic Polypeptide, bovine inhibits secretin- and cholecystokinin-stimulated pancreatic secretion. 125I-Pancreatic Polypeptide, bovine shows no specific binding to pancreatic acini.
In Vivo: Pancreatic Polypeptide (25 nmol/kg bw, i.p.) 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.
