lysozyme is a bactericidal enzyme whose structure and functions change in diabetes. chemical chaperones are small molecules including polyamines (e.g. spermine), amino acids (e.g. l-lysine) and polyols (e.g. glycerol). they can improve protein conformation in several stressful conditions such as glycation. in this study, the authors aimed to observe the effect of l-lysine as a chemical chaperon...

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 a...

Glycation, the nonenzymatic glycosylation of biomolecules, is commonly observed in diabetes and ageing. Reactive dicarbonyl species such as methylglyoxal and glyoxal are thought to be major physiological precursors of glycation. Because these dicarbonyls tend to be formed intracellularly, the levels of advanced glycation end products on cellular proteins are higher than on extracellular ones. T...

BACKGROUND AND PURPOSE Following intracerebral hemorrhage (ICH), high-mobility group box 1 protein (HMGB1) may promote neurogenesis that supports functional recovery. How HMGB1 regulates or participates in this process is unclear, as are the pattern recognition receptors and signaling pathways involved. METHODS ICH was induced by injection of collagenase in Sprague-Dawley rats, which were tre...

Abstract Glycation is a spontaneous post-translational modification of lysine, arginine, and the N-terminus proteins. Protein glycation closely related to pathogenesis human diseases, including diabetes, Alzheimer’s disease, renal cancer. The levels advanced end products (AGEs) are positively correlated with progression many diseases. However, it remains challenging analyze glycation-related pr...

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...

BACKGROUND The matrine-type alkaloids are bioactive components extracted from Sophora flavescens, which is used in treatment of diabetes mellitus in traditional Chinese medicine. Advanced glycation end products mediate diabetic vascular complications. This study was aimed to investigate the protective effects and molecular mechanisms of matrine-type alkaloids on advanced glycation end products-...
