Introduction

guidelines
Uridine 5'-diphosphate-GlcNAc (UDP-Glc-NAc )respond to nutrient excess to activate O-GlcNAcylation (addition of O-linked N-acetylglucosamine) in the hexosamine signaling pathway (HSP). O-GlcNAc addition (and removal) is key to histone remodeling, transcription, proliferation, apoptosis, and proteasomal degradation. This nutrient-responsive signaling pathway also modulates important cellular pathways, including the insulin signaling cascade in. Alterations in O-GlcNAc metabolism are associated with various human diseases including diabetes mellitus and neurodegeneration. (PMID: 16317114) The incidence of type 2 diabetes (non-insulin-dependent diabetes mellitus) has increased to epidemic proportions, being described as a disease of 'chronic overnutrition'. Due to the chemical makeup of UDP-GlcNAc,it is well positioned to serve as a glucose sensor in that it is a high-energy compound that requires and/or responds to glucose, amino acid, fatty acid and nucleotide metabolism for synthesis. UDP-Glc-NAc is the donor substrate for modification of nucleocytoplasmic proteins at serine and threonine residues with N-acetylglucosamine. Elevated levels of O-GlcNAc have an effect on insulin-stimulated glucose uptake. (PMID: 12678487)
