The lipid peroxidation product 4-hydroxy-2-nonenal: Advances in chemistry and analysis☆
4-Hydroxy-2-nonenal (HNE) is one of the most studied products of phospholipid peroxidation, owing to its reactivity and cytotoxicity. It can be formed by several radical-dependent oxidative routes involving the formation of hydroperoxides, alkoxyl radicals, epoxides, and fatty acyl cross-linking reactions. Cleavage of the oxidized fatty acyl chain results in formation of HNE from the methyl end...
متن کامل4-Hydroxy-nonenal—A Bioactive Lipid Peroxidation Product †
This review on recent research advances of the lipid peroxidation product 4-hydroxy-nonenal (HNE) has four major topics: I. the formation of HNE in various organs and tissues, II. the diverse biochemical reactions with Michael adduct formation as the most prominent one, III. the endogenous targets of HNE, primarily peptides and proteins (here the mechanisms of covalent adduct formation are desc...
متن کاملThe covalent modification of spectrin in red cell membranes by the lipid peroxidation product 4-hydroxy-2-nonenal.
Spectrin strengthens the red cell membrane through its direct association with membrane lipids and through protein-protein interactions. Spectrin loss reduces the membrane stability and results in various types of hereditary spherocytosis. However, less is known about acquired spectrin damage. Here, we showed that alpha- and beta-spectrin in human red cells are the primary targets of the lipid ...
متن کاملThe lipid peroxidation product 4-hydroxy-2-nonenal induces tissue factor decryption via ROS generation and the thioredoxin system.
Many pathophysiologic agents transform cryptic tissue factor (TF) on cells to prothrombotic TF, and one such stimulus is 4-hydroxy-2-nonenal (HNE), the most abundant aldehyde produced by the oxidation of ω-6 polyunsaturated fatty acids. HNE was shown to induce reactive oxygen species (ROS) generation and p38 MAPK activation, but the link between them and their role in TF decryption are unclear....
متن کاملThe lipid peroxidation product, 4-hydroxy-2-trans-nonenal, alters the conformation of cortical synaptosomal membrane proteins.
Alzheimer's disease (AD) is widely held to be a disorder associated with oxidative stress due, in part, to the membrane action of amyloid beta-peptide (A beta). A beta-associated free radicals cause lipid peroxidation, a major product of which is 4-hydroxy-2-trans-nonenal (HNE). We determined whether HNE would alter the conformation of synaptosomal membrane proteins, which might be related to t...
