neuromedin u

Neuromedin U (rat) acetate 是一种 23 个氨基酸的脑肠肽。 Neuromedin U (NMU) 通过其在中枢神经系统中的同源受体 NMUR2 调节几种重要的生理功能，包括能量平衡、压力反应和伤害感受。

Neuromedin U,a 23-amino acid brain-gut peptide, regulates several important physiological functions through its cognate receptor NMUR2 in the central nervous system, including energy balance, stress response, and nociception.

Neuromedin U, rat TFA is a 23-amino acid brain-gut peptide.

Neuromedin U (NMU) is a neuropeptide first demonstrated to drive smooth muscle contraction.1Translated as a 174 amino acid propeptide, NMU is cleaved to different lengths in different animals. It has diverse receptor-mediated rolesin vivo, as it regulates feeding, vasoconstriction, nociception, and bone remodeling and contributes to obesity, cancer and septic shock.2,2NMU-25 is the active form of NMU in humans. It binds with high affinity to receptors on human left ventricle and coronary artery (KDs = 0.26 and 0.11 nM, respectively), eliciting endothelium-independent vasoconstriction.3NMU-25 also suppresses glucose-stimulated insulin secretion in human islets, and this effect is lost in NMU R165W mutants, resulting in early-onset obesity.4 1.Mitchell, J.D., Maguire, J.J., and Davenport, A.P.Emerging pharmacology and physiology of neuromedin U and the structurally related peptide neuromedin SBritish Journal of Pharmacology15887-103(2009) 2.Greenwood, H.C., Bloom, S.R., and Murphy, K.G.Peptides and their potential role in the treatment of diabetes and obesityRev.Diabet.Stud.8(3)355-368(2011) 3.Mitchell, J.D., Maguire, J.J., Kuc, R.E., et al.Expression and vasoconstrictor function of anorexigenic peptides neuromedin U-25 and S in the human cardiovascular systemCardiovascular Research81353-361(2009) 4.Alfa, R.W., Park, S., Skelly, K.R., et al.Suppression of insulin production and secretion by a decretin hormoneCell Metabolism21(2)323-333(2015)
