4-Hydroxy-nonenal—A Bioactive Lipid Peroxidation Product †
نویسندگان
چکیده
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 described and the (patho-) physiological consequences discussed), and IV. the metabolism of HNE leading to a great number of degradation products, some of which are excreted in urine and may serve as non-invasive biomarkers of oxidative stress.

A 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 کاملElevated protein-bound levels of the lipid peroxidation product, 4-hydroxy-2-nonenal, in brain from persons with mild cognitive impairment.
Oxidative damage is a feature of many age-related neurodegenerative diseases, including Alzheimer's disease (AD). 4-Hydroxy-2-nonenal (HNE) is a highly reactive product of the free radical-mediated lipid peroxidation of unsaturated lipids, particularly arachidonic acid, in cellular membranes. In the present study we show for the first time in brain obtained at short postmortem intervals that th...

The study was designed with an aim to evaluate the protective effects of reduced glutathione on cyclophosphamide induced lipid peroxidation and also changes in cholesterol content. Goat liver and white New Zealand rabbit were used as lipid source for the models. Lipid peroxidation study was performed by measuring the malondial...
متن کاملLipid peroxidation product 4-hydroxynonenal as factor of oxidative homeostasis supporting bone regeneration with bioactive glasses.
Bone regeneration is a process of vital importance since fractures of long bones and large joints have a highly deleterious impact on both, individuals and society. Numerous attempts have been undertaken to alleviate this severe medical and social problem by development of novel bioactive materials, among which bioactive glass is the most attractive because of its osteoconductive and osteostimu...
متن کاملCytotoxicity and metabolism of 4 - hydroxy - 2 - nonenal and 2 - nonenal in H 202 - resistant cell lines
Toxic aldehydes, such as 4-hydroxy-2-nonenal (4HNE) and 2-nonenal (2NE), formed during lipid peroxidation have been isolated and implicated in the cytotoxic effects of oxidative stress. We have investigated the cytotoxicity and metabolism of 4HNE and 2NE in control (HA-1) cells and in two H202-resistant Chinese hamster fibroblast cell lines. The H202resistant cells were found to be significantl...
