Increased glycolytic flux into the diabetic kidney, combined with glycolytic inefficiencies introduced by oxidative stress, acts to increase the generation of triose-phosphate intermediates, which spontaneously degrade to form methylglyoxal. At the same time, the glyoxalase-catalysed pathway that degrades excess methylglyoxal is impaired. The resulting dicarbonyl stress increases the accumulation of Advanced Glycation End-products (AGEs), as highly reactive dicarbonyls modify proteins, DNA, phospholipids and even small molecules like glutathione and nitric oxide. The resulting molecular dysfunction, contributes to the development and progression of kidney disease in diabetes. The importance ..
