Identification of a negative feedback loop in biological oxidant formation fegulated by 4-hydroxy-2-(E)-nonenal
4-Hydroxy-2-(E)-nonenal (4-HNE) is one of the major lipid peroxidation product formed during oxidative stress. At high concentrations, 4-HNE is cytotoxic and exerts deleterious effects that are often associated with the pathology of oxidative stress-driven disease. Alternatively, at low concentrations it functions as a signaling molecule that can activate protective pathways including the antio...
متن کاملFormation of (2E)-4-Hydroxy-2-nonenal and (2E)-4-Hydroxy-2-hexenal by Plant Enzymes: A Review Suggests a Role in the Physiology of Plants
It is demonstrated that (3Z)-nonenal (NON) and (3Z)-hexenal (HEX) are oxidized in a cascade by lipoxygenase (LOX) and hydroperoxide peroxygenase (HP peroxygenase) into (2E)-4-hydroxy-2nonenal (HNE) and (2E)-4-hydroxy-2-hexenal (HHE), respectively. In turn, HNE inactivates LOX terminating the cascade. The hydroxy-alkenals produced serve to inhibit plant pathogens, which initiated the cascade. In...
متن کاملLipid peroxidation and 4-hydroxy-2-nonenal formation by copper ion bound to amyloid-beta peptide.
The lipid peroxidation product 4-hydroxy-2-nonenal (HNE) is proposed to be a toxic factor in the pathogenesis of Alzheimer disease. The primary products of lipid peroxidation are phospholipid hydroperoxides, and degraded reactive aldehydes, such as HNE, are considered secondary peroxidation products. In this study, we investigated the role of amyloid-beta peptide (A beta) in the formation of ph...
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...
