Glycation is a non-enzymatic process occurring inside or outside the host body by attaching a sugar molecule to a protein or lipid molecule. It is an important form of post-translational modification (PTM), which impairs the function and changes the characteristics of the proteins so that the identification of the glycation sites may provide some useful guidelines to understand various biologic...
Some suggest that measurements of plasma fructosamine concentration should be corrected for the plasma protein (or albumin) concentration because the extent of glycation per volume depends on both protein and glucose concentrations. Several reports, however, demonstrate a poor correlation between plasma fructosamine and albumin concentrations in diabetic patients. In vitro kinetic and in vivo s...
INTRODUCTION 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...
Advanced glycation end products (AGEs) play an important factor for pathophysiology of diabetes and its complications. Moringa oleifera is one of the medicinal plants that have anti-hyperglycemic activity. However, anti-glycation property of Moringa oleifera leaf extract on the different types of reducing monosaccharides-induced protein glycation has not been investigated. Therefore, the aim of...
The mechanisms involving iron toxicity in diabetes mellitus are not completely understood. However, the spontaneous reaction of reducing sugars with protein amino groups, known as glycation, has been shown to compromise the action of Tf (transferrin), the systemic iron transporter. In order to understand the structural alterations that impair its function, Tf was glycated in vitro and the modif...
We investigated the influence of glycated low density lipoprotein (LDL) for vascular smooth muscle cell (SMC) proliferation or injury. We utilized glycated, slightly oxidized LDL (GLDL-LOX), glycated, auto-oxidized LDL (GLDL) and glycated, metal-induced extensively oxidized LDL (GLDL-OX) to examine the effect of glycation itself or combined glycation and oxidation on SMC. GLDL-LOX induced SMC p...
Naturally occurring anti-glycation compounds have drawn much interest in recent years as they show potential in reducing or preventing the risk of chronic complications for diabetic patients. In this study, annotation of the genome-transcriptome data from tiger milk mushroom (Lignosus rhinocerus, syn. Lignosus rhinocerotis) to PlantCyc enzymes database identified transcripts that are related to...
Vitamin C, an antioxidant substance soluble in water, can react with amino groups of proteins to form schiff bases. As diabetes leads to glycation of various protein which has effect on structure and biochemical activity of them, the inhibition of this process seems very vital. For several years researches in this field have done their best to recognize the antidiabetics compounds. The aim of t...
conclusions these results revealed that resveratrol has beneficial effects on kidney by extenuating the oxidative stress and down-regulation of rage expression. results in resveratrol-treated rats with diabetes, malondialdehyde levels, plasma glucose and expression of rage were significantly reduced compared with the untreated group. moreover, the total antioxidant and insulin levels significan...
INTRODUCTION Non-enzymatic glycation of proteins has been implicated in various diabetic complications and age-related disorders. Proteins undergo glycation at the N-terminus or at the epsilon-amino group of lysine residues. The observation that only a fraction of all lysine residues undergo glycation indicates the role of the immediate chemical environment in the glycation reaction. Here we ha...
