Acetohexamide is a drug used to treat type II diabetes and is tightly bound to the protein human serum albumin (HSA) in the circulation. It has been proposed that the binding of some drugs with HSA can be affected by the non-enzymatic glycation of this protein. This study used high-performance affinity chromatography to examine the changes in acetohexamide-HSA binding that take place as the gly...

The use of different expression systems to produce the same recombinant human protein can result in expression-dependent chemical modifications (CMs) leading to variability of structure, stability and immunogenicity. Of particular interest are recombinant human proteins expressed in plant-based systems, which have shown particularly high CM variability. In studies presented here, recombinant hu...

OBJECTIVE This study aims to evaluate the relationship between tissue advanced glycation end products, as reflected by skin autofluorescence, and vascular calcification in chronic kidney disease. APPROACH AND RESULTS Three hundred patients with stage 3 to 5 chronic kidney disease underwent multislice computed tomography to estimate total coronary artery calcium score (CACS) and had tissue adv...

Advanced glycation end products (AGEs), generated through nonenzymatic glycosylation of proteins, lipids, and nucleic acids, accumulate in the body by age thus being considered as biomarkers of senescence. Senescence is characterized by a breakdown of immunological self-tolerance, resulting in increased reactivity to self-antigens. Previous findings suggest that AGE and its receptor RAGE may be...

hsa plays an important role in transporting metabolites and drugs throughout the vascular system.  in as much as its performance is very vital in the presents of different kinds of ligands at the specific body temperatures, its examination is crucial. this molecule can undergo increased glycation in diabetes. therefore, glucose as the one of the most fundamental ligands dealing with albumin in ...

BACKGROUND Atherosclerosis is an inflammatory disease in which a perpetuated activation of NFkappaB via the RAGE (receptor for advanced glycation end products)-MAPK signalling pathway may play an important pathogenetic role. As recently S100 proteins have been identified as ligands of RAGE, we sought to determine the effects of the proinflammatory heterodimer of S100A8/S100A9 on the RAGE-NFkapp...

the non-enzymatic glycation of low density lipoprotein (ldl) is a naturally occurring chemical modification of apolipoprotein b as a result of condensation between lysine residues and glucose. glycated ldl is poorly recognized by ldl receptors and initiates different processes that can be considered proatherogenic. thus, ldl glycation may contribute in the increased atherosclerotic risk of pati...

nonenzymatic glycation of low density lipoprotein (ldl) is a reaction of glucose and other reducing sugars with apolipoprotein b100 (apo-b100) lysine residues. in diabetes, this reaction is greatly accelerated and is important in the pathogenesis of diabetic complications. the objective of this study was to investigate in vitro effects of ?-tocopherol, ascorbic acid and lycopene on ldl glycatio...
