  • Title: NPY L7P polymorphism and metabolic diseases.
    Author: Pesonen U.
    Journal: Regul Pept; 2008 Aug 07; 149(1-3):51-5. PubMed ID: 18499283.
    Abstract:
    Neuropeptide Y (NPY) is an abundant and widespread peptide in mammalian nervous system, both in the central and peripheral nervous systems. NPY is a multifunctional neurotransmitter with multiple modulator effects in the regulation of physiological functions and responses in the body. NPY is a potent orexigenic peptide, which has effects on energy balance at the level of energy intake, expenditure, and partition. There are many association studies between the NPY gene variants and cardiovascular and metabolic disease. Most of them are done by using p.L7P substitution as a marker. At the moment it seems that the p.L7P substitution of preproNPY protein causes altered NPY secretion, which leads to haemodynamic disturbances caused by sympathetic hyperactivity and to various effects caused by altered local signalling by NPY. SNP association studies using p.L7P polymorphism suggest that this functional substitution may be a strong independent risk factor for various metabolic and cardiovascular diseases.
