Bohlender, Jürgen M., Sybille Franke, Günter Stein, and Gunter Wolf. Advanced glycation end products and the kidney. Am J Physiol Renal Physiol 289: F645–F659, 2005; doi:10.1152/ajprenal.00398.2004.—Advanced glycation end products (AGEs) are a heterogeneous group of protein and lipids to which sugar residues are covalently bound. AGE formation is increased in situations with hyperglycemia (e.g....

Throughout the industrialized (well-fed) Adverse effects of hyperglycaemia, once thought an epiphenomenon in the pathogenesis of diabetic microworld, diabetes mellitus is the most prevalent cause of end-stage renal disease (ESRD). Diabetic nephropathy and macrovascular complications, presently are a central focus of active clinical and basic investigation is as likely to develop in long-duratio...

Methylglyoxal can yield advanced glycation end products via nonenzymatic glycation of proteins. Whether methylglyoxal contributes to the pathogenesis of hypertension has not been clear. The aim of the present study was to investigate whether the levels of methylglyoxal and methylglyoxal-induced advanced glycation end products were enhanced and whether methylglyoxal increased oxidative stress, a...

Long-term continuous ambulatory peritoneal dialysis (CAPD) often causes peritoneal fibrosis and sclerosis with a loss of function, and some CAPD patients develop sclerosing encapsulating peritonitis. Glucose-based peritoneal dialysis fluids readily produce glucose degradation products by heat sterilization, and glucose degradation products accelerate the formation of advanced glycation end-prod...

Advanced glycation end products (AGEs) may play an important adverse role in process of atherosclerosis, diabetes, aging and chronic renal failure. Levels of N(epsilon)-carboxymethyllysine and fluorescent AGE values were estimated in two nutritional population groups--alternative group (vegetarians--plant food, milk products, eggs) and traditional group (omnivorous subjects). Vegetarians have a...

Advanced glycation end products (AGEs) are a heterogeneous, complex group of compounds that are formed when reducing sugar reacts in a non-enzymatic way with amino acids in proteins and other macromolecules. This occurs both exogenously (in food) and endogenously (in humans) with greater concentrations found in older adults. While higher AGEs occur in both healthy older adults and those with ch...

During long standing hyperglycaemic state in diabetes mellitus, glucose forms covalent adducts with the plasma proteins through a non-enzymatic process known as glycation. Protein glycation and formation of advanced glycation end products (AGEs) play an important role in the pathogenesis of diabetic complications like retinopathy, nephropathy, neuropathy, cardiomyopathy along with some other di...

Recent studies suggest that advanced glycation endproducts play an important role in cardiovascular complications of ageing, diabetes and end-stage renal failure. Since highly elevated levels of advanced glycation endproducts are present in serum of patients on maintenance haemodialysis, an accurate and rapid assay for their determination would be useful. This would be particularly valuable for...

Objective(s): This study aims to investigate the pathogenicity and possible mechanisms of S100A9 function in mice models of scleroderma. Materials and Methods: The content of S100A9 in the skin tissues of mice with scleroderma was determined. Different concentrations of bleomycin (BLM) and S100A9 were subcutaneously injected into the backs of mice simultaneously, and then pathological changes i...

A commonality among the chemically disparate compounds that inhibit the formation and accumulation of advanced glycation end products (AGEs) or their signalling pathways is their end organ protection in experimental models of diabetes complications. Although this group of therapeutics are structurally and functionally distinct with numerous mechanisms of action, the most important factor govern...
