We found a potent hyperglycemic effect of proadrenomedullin N‐terminal 20 peptide (PAMP) after intra‐third cerebroventricular administration at a dose of 10 nmol in fasted mice. PAMP has four homologous residues with bombesin (BN), a hyperglycemic peptide. PAMP showed affinity for gastrin‐releasing peptide preferring receptor (GRP‐R) and neuromedin B preferring receptor. The PAMP‐induced hyperglycemic effect was inhibited by [D‐Phe6, Leu‐NHEt13, des‐Met14]‐BN (6–14), GRP‐R specific antagonist, indicating that the hyperglycemic effect is mediated at least in part via GRP‐R. Furthermore, pretreatment of α‐adrenergic blocker inhibited the PAMP‐induced hyperglycemia and hyperglucagonemia, suggesting that the increase of glucagon secretion through α‐adrenergic activation is involved in this hyperglycemic effect of PAMP.
