The 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 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 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 کاملInduction of rat aortic smooth muscle cell growth by the lipid peroxidation product 4-hydroxy-2-nonenal.
BACKGROUND Atherosclerotic lesion formation is a complex process, in part mediated by inflammatory and oxidative mechanisms including lipid peroxidation. To further characterize the potential role of lipid peroxidation products in atherogenesis, we studied the effects of 4-hydroxy-2-nonenal (HNE) on rat aortic smooth muscle cell growth. METHODS AND RESULTS HNE, at concentrations of 1.0 and 2....
متن کاملMass spectrometric characterization of covalent modification of human serum albumin by 4-hydroxy-trans-2-nonenal.
Several pieces of evidence indicate that albumin modified by HNE is a promising biomarker of systemic oxidative stress and that HNE-modified albumin may contribute to the immune reactions triggered by lipid peroxidation-derived antigens. In this study, we found by HPLC analysis that HNE is rapidly quenched by human serum albumin (HSA) because of the covalent adduction to the different accessibl...
