Effect 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 کاملEnantioselective oxidation of trans-4-hydroxy-2-nonenal is aldehyde dehydrogenase isozyme and Mg2+ dependent.
trans-4-Hydroxy-2-nonenal (HNE) is a cytotoxic alpha,beta-unsaturated aldehyde implicated in the pathology of multiple diseases involving oxidative damage. Oxidation of HNE by aldehyde dehydrogenases (ALDHs) to trans-4-hydroxy-2-nonenoic acid (HNEA) is a major route of metabolism in many organisms. HNE exists as two enantiomers, (R)-HNE and (S)-HNE, and in intact rat brain mitochondria, (R)-HNE...
متن کاملA study on ceftriaxone-induced lipid peroxidation using 4-hydroxy-2-nonenal as model marker.
4-Hydroxy-2-nonenal, an indicator of lipid peroxidation process. was used as model marker to explore ceftriaxone-induced lipid peroxidation in goat liver homogenate. Ceftriaxone was found to induce lipid peroxidation significantly. It was further found that ascorbic acid could significantly arrest ceftriaxone-induced lipid peroxidation. The results corroborate the earlier findings with malondia...
متن کاملSynaptosomal 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 کاملPhosphatidylinositol 3 kinase pathway and 4-hydroxy-2-nonenal-induced oxidative injury in the RPE.
PURPOSE 4-Hydroxy-2-nonenal (4-HNE) is a major lipid peroxidation product in the retina and the retinal pigment epithelium. The purpose of the present study was to investigate how NF-E2-related factor-2 (Nrf2) and phosphatidylinositol 3 (PI3K) pathways affect the responses of cultured human retinal pigment epithelial (RPE) cells to 4-HNE. METHODS Cultured ARPE-19 cells were treated with diffe...
