Synaptosomal Toxicity and Nucleophilic Targets of 4-Hydroxy-2-Nonenal
4-Hydroxy-2-nonenal (HNE) is an aldehyde by-product of lipid peroxidation that is presumed to play a primary role in certain neuropathogenic states (e.g., Alzheimer disease, spinal cord trauma). Although the molecular mechanism of neurotoxicity is unknown, proteomic analyses (e.g., tandem mass spectrometry) have demonstrated that this soft electrophile preferentially forms Michael-type adducts ...
متن کاملEffect of 4-Hydroxy-2-Nonenal Modification on -Synuclein Aggregation
Several observations have implicated oxidative stress and aggregation of the presynaptic protein-synuclein in the pathogenesis of PD.-Synuclein has been shown to have affinity for unsaturated fatty acids and membranes enriched in PUFAs, which are especially sensitive to oxidation under conditions of oxidative stress. One of the most important products of lipid oxidation is 4-hydroxynonenal (H...
متن کاملFormation of 4-hydroxy-2-nonenal-modified proteins in ischemic rat heart.
4-Hydroxy-2-nonenal (HNE) is a major lipid peroxidation product formed during oxidative stress. Because of its reactivity with nucleophilic compounds, particularly metabolites and proteins containing thiol groups, HNE is cytotoxic. The aim of this study was to assess the extent and time course for the formation of HNE-modified proteins during ischemia and ischemia plus reperfusion in isolated r...
متن کاملAntibodies against 4-Hydroxy-2-nonenal Modified Epitopes Recognized Chromatin and Its Oxidized Forms: Role of Chromatin, Oxidized Forms of Chromatin and 4-Hydroxy-2-nonenal Modified Epitopes in the Etiopathogenesis of SLE
OBJECTIVES This study was undertaken to investigate the role of lipid oxidative-by-product 4-hydroxy-2-nonenal (HNE)-modified human serum albumin (HSA), chromatin, reactive oxygen species (ROS)-modified chromatin and nitric oxide (NO)-modified chromatin in systemic lupus erythematosus (SLE). METHODS HSA was modified by HNE. Immunogenicity of modified HSA was probed by inducing polyclonal anti...
متن کاملFatty Acids are Key in 4-Hydroxy-2-Nonenal-Mediated Activation of Uncoupling Proteins 1 and 2
The production of reactive oxygen species (ROS) in mitochondria is very sensitive to the proton motive force and may be decreased by mild uncoupling, mediated e.g. by mitochondrial uncoupling proteins (UCPs). UCPs were conversely hypothesized to be activated by ROS. Conclusions from experiments studying the reactive product of lipid peroxidation 4-hydroxy-2-nonenal (HNE) in isolated mitochondri...
