Introduction: Diabetes mellitus is one of the most common diseases in the world that imposes a tremendous health and societal burden whether that burden is measured in terms of sickness, use of health systems resources or costs. Hyperglycemia is the most important clinical sign of diabetes leading to glycation of the various proteins in the body that leading to change in nature, structure and...
Albumin, the major circulating protein in blood, can undergo increased glycation in diabetes. One of the main properties of this plasma protein is its strong affinity to bind many therapeutic drugs, including warfarin and ketoprofen. In this study, we investigated whether or not there were any significant changes related to in vitro or in vivo glycation in the structural properties and the bind...
in this study, we examined the antioxidant activities of methanolic extract of three endemic species of salvia from iran (s. lachnocalyx, s. reuterana and s. sahendica) employing various established in vitro systems including ferric reducing antioxidant power, trolox equivalent antioxidant capacity assay and scavenging of 1,1-diphenyl-2-picrylhydrazyl radical. the results revealed that s. reute...
AIM Albumin, a major protein in the blood circulation, can undergo increased glycation in diabetes. From recent studies, it has become evident that glycation has important implications for albumin actions and impact on cell functioning. This study compares the structural and functional properties of albumin glycated by glucose and methylglyoxal (MGO) with those of albumin purified from diabetic...
We tested whether polyphenolic substances in extracts of commercial culinary herbs and spices would inhibit fructose-mediated protein glycation. Extracts of 24 herbs and spices from a local supermarket were tested for the ability to inhibit glycation of albumin. Dry samples were ground and extracted with 10 volumes of 50% ethanol, and total phenolic content and ferric reducing antioxidant poten...
Hyperglycemia-induced oxidative stress plays a key role in the onset/progression of cardiovascular diseases. For example, it can trigger formation of advanced glycation end (AGE) products with ischemia-reperfusion performed under hyperglycemic conditions. For this study, we hypothesized that albumin modified by glycation loses its unique cardioprotective properties in the setting of ischemia-re...
Albumin is the most common protein found in serum, making up about 80% concentration of the circulating blood protein. It is replaced in the body approximately every 20-25 days. As with other proteins in the body, it is subject to non-enzymatic glycation by excess sugar. The glycation process is a condensation reaction between carbohydrate and free amino acid at the amino terminus of proteins o...
Non-enzymatic glycation of proteins is the major cause of diabetic complications and therefore, inhibition of this reaction could reduce the morbidity of this disease. The aim of this study was to evaluate the in vitro effects of aqueous and hydroethanol extracts of Echium italicum L., Anchusa arvensis L. and Trichodesma incanum (Bunge) A. DC. of Boraginaceae on albumin, hemoglobin, and crystal...
Human serum albumin has been used as a model protein for protein folding and ligand binding studies over many decades. Due to its long life period and high concentration in plasma, HSA is highly sensitive to glycation. It is reported that 175 mg/dL glucose concentration is a threshold of kidney activity for the beginning of excretion of glucose. pH denaturation of HSA in absence and presence of...
