The Role of Advanced Glycation End Products in Progression and Complications of Diabetes

CONTEXT: Diabetic complications appear to be multifactorial in origin, but in particular, the biochemical process of advanced glycation, which is accelerated in diabetes as a result of chronic hyperglycemia and increased oxidative stress, has been postulated to play a central role in these disorders. Advanced glycation involves the generation of a heterogenous group of chemical moieties known as advanced glycated end products (AGEs), this reaction occurring as a result of a nonenzymatic reaction with glucose interacting with proteins, lipids, and nucleic acids, and involves key intermediates such as methylglyoxal. EVIDENCE SYNTHESIS: In this review we report on how these AGEs may exert deleterious effects in…
