Abstract:Hyperglycemia plays an important role in the pathogenesis of diabetic complications including accumulation of methylglyoxal (MG), a highly reactive α-dicarbonyl metabolite of glucose degradation pathways. MG reacts in a non-enzymatic reaction with arginine residues of proteins which results in the formation of argpyrimidine. In several cell lines Hsp27 was found to be the most argpyrimidine containing protein. Whether Hsp27, which is high expressed in cardiac tissue, is also modified in heart, remains unclear.… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
