The Maillard reaction, which is generally termed nonenzymatic browning or glycation, has been implicated in accelerated aging and diabetic complications in vivo. Although the molecular basis of glycation-induced pathogenesis is not well understood, the following have been noted: (1) protein glycation leads to the formation and accumulation of toxic advanced(More)
Increasing evidence has shown advanced glycation end products (AGEs) receptor ligation (RAGE) to be an important part of complex interactions of the oxidative stress and pro-inflammatory responses. In this study, flavonoids were used to monitor the protective effects against the oxidative damage and inflammation mediated by AGEs in human monocytes. S100B(More)
The current study was designed to evaluate the effects of silymarin (SM) on advanced glycation endproduct (AGE) formation and monocyte activation induced by S100b, a specific ligand of receptor for AGEs. The in vivo verification of antiglycation, antioxidant, and antiinflammatory capacities was examined by 12 weeks of SM administration in(More)
In this study, the effects of phenolic acids [caffeic acid (CA), ferulic acid, m-coumaric acid, and chlorogenic acid] on methylglyoxal (MG)-induced protein glycation were investigated in vitro. Sodium dodecyl sulfate polyacrylamide gel electrophoresis and advanced glycation end products (AGEs)-specific fluorescence showed that MG-mediated protein(More)
In the process of glycation, methylglyoxal is a reactive dicarbonyl compound physiologically generated as an intermediate of glycolysis, and is found in high levels in blood or tissue of diabetic models. Biological glycation has been commonly implicated in the development of diabetic microvascular complications of neuropathy. Increasing evidence suggests(More)
SCOPE This study investigated whether flavonoids, such as hesperetin and hesperidin, inhibited amyloid β (Aβ)-impaired glucose utilization through regulating cellular autophagy in insulin-stimulated neuronal cells. METHODS AND RESULTS In this study, we used a toxic Aβ1-42 peptide to impair insulin-stimulated glucose utilization in Neuro-2A cells, and this(More)
Methylglyoxal is a reactive dicarbonyl compound generated as an intermediate of glycolysis during the physical glycation in the diabetic condition. It is considered to be a potent precursor of advanced glycation end products (AGEs) formation. Methylglyoxal itself and methylglyoxal-derived AGEs have been commonly implicated in the development of diabetic(More)
The purpose of this study was to investigate the distinct roles of advanced glycation end products (AGEs) on insulin-mediated glucose disposal in 3T3-L1 adipocytes and C2C12 skeletal muscle cells. AGE-modified proteins, namely, GO-AGEs, were prepared by incubating bovine serum albumin (BSA) with glyoxal (GO) for 7 days. Glucose utilization rates and the(More)
The fruit of Artocarpus communis Moraceae, a traditional starch crop, is a rich source of phytochemicals, such as flavonoids and their derivatives. The aim of this study was to investigate whether 5,7,4'-trihydroxy-6-geranylflavanone (AC-GF), a geranyl flavonoid derivative isolated from the fruits of A. communis, could decrease the activation of(More)
SCOPE Oxidative stress-aggravated chronic inflammatory diseases of the airway are well documented; hence, treatment with antioxidants to ameliorate oxidative stress might be an effective strategy to reduce airway complications. The aim of this study was to investigate the effect and molecular mechanism of diallyl sulfide (DAS), which is a natural(More)
