The reactivity of α-oxoaldehyde with reactive oxygen species in diabetes complications
نویسندگان
چکیده
The reactions of three α-oxoaldehydes (methylglyoxal, glyoxal, and pyruvic acid) with hydroxyl radicals generated by sonolysis of water were investigated using an electron spin resonance (electron paramagnetic resonance) spin-trapping method, and their reaction kinetics were investigated. It is apparent from our experimental results that methylglyoxal exhibits the highest reactivity of the three α-oxoaldehydes. These α-oxoaldehydes can react with hydroxyl radicals faster than other well-known antioxidants can. The reactivity of hydroxyl radicals is higher than that of hydrogen peroxides.

Reactive oxygen species mediate TNF-α-induced inflammatory response in bone marrow mesenchymal cells
Objective(s): It is generally believed that the inflammatory response in bone marrow mesenchymal stem cells (BMSCs) transplantation leads to poor survival and unsatisfactory effects, and is mainly mediated by cytokines, including interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α). In this study, we explored the mechanisms underlying the TNF-α-induced inflammatory ...
متن کاملInduction of Activating Transcription Factor 6 via Activation of ERK and ROS-P38 MAPK is Related to Methylglyoxal-Induced Cytotoxicity in Human Retinal Pigment Epithelial Cells
Methylglyoxal (MGO), a reactive α-oxoaldehyde produced by glucose metabolism, is elevated in several diabetic complications, including diabetic retinopathy. The breakdown of retinal pigment epithelial cells is implicated in the progression of diabetic retinopathy. Increased concentrations of MGO lead to retinal pigment epithelial cell death. In this study, we investigated the involvement of act...

The present study was designed to determine the effects of the essential oil of Laurusnobilis L. (Lauraceae) and its three main components on α-glucosidase and reactive oxygenspecies scavenging activity. The chemical composition of the essential oil from Laurus nobilisL. leaves was analyzed by GC/GC-MS and resulted in the identification of 29 compounds,representing 99.18% of the total oil. 1,8-...

متن کاملDiabetes and Oxidative Stress: The Mechanism and Action
Abstract Diabetes mellitus is one of the major metabolic disorders. Diabetes is recognized for severe complications including diabetic nephropathy, neuropathy and retinopathy. Long-lasting effect of hyperglycemia results in increased oxidative stress. Oxidative stress results from an imbalance between radical-generating and radical scavenging systems. Increased oxidative stress has been shown ...
