Most of the biological effects of intermediate RCS, mainly alpha,beta-unsaturated aldehydes, di-aldehydes, and keto-aldehydes, are due to their capacity to react with the nucleophilic sites of proteins, forming advanced lipoxidation end-products (ALEs).

Intervention strategies to inhibit protein carbonylation by lipoxidation‐derived reactive carbonyls 3. Pathophysiological relevance of lipoxidation adducts. Evidence for occurrence of lipoxidation products in vivo has expanded greatly in the last 10 years, as more sensitive and specific methodology has been developed, and now there are many examples of lipoxidized proteins in both healthy and diseased tissues. Much of the work has focused on HNE, but there are also many examples of adducts
The Amadori products undergo dehydration and rearrangements and develop a cross-link between adjacent proteins, giving rise to protein aggregation or advanced glycation end products (AGEs). A number of studies have shown that glycation induces the formation of the β-sheet structure in β-amyloid protein, α-synuclein, transthyretin (TTR), copper-zinc superoxide dismutase 1 (Cu, Zn-SOD-1), and

Sigma-Aldrich offers abstracts and full-text articles by [Rosemary E McDowell, Mary K McGahon, Josy Augustine, Mei Chen, J Graham McGeown, Tim M Curtis]. Similarly, advanced glycation end products (AGEs) are formed by reaction of carbonyl substances such as carbohydrates and proteins . ROS and RNS can also damage nucleic acids, generating pyrimidine and purine base adducts. 8-oxo-2 - deoxyguanosine is thought to be the most representative product of oxidative modifications of DNA and can correlate with the level of oxidative DNA damage in the
Lipoxidation reactions and the subsequent accumulation of advanced lipoxidation end products (ALEs) have been implicated in the pathogenesis of many of the leading causes of visual impairment. Here, we begin by outlining some of the major lipid aldehydes produced through lipoxidation reactions, the ALEs formed upon their reaction with proteins, and the endogenous aldehyde metabolizing enzymes involved in protecting cells against lipoxidation mediated damage.
Advanced glycoxidation [1 – 3] end products (AGEs) and advanced lipoxidation end-products (ALEs) are widely studied as reporters of oxidative and glycoxidative damage [4 – 8]. The most common analytical methods for their quantitative determination are based on ELISA or … Most of the biological effects of RCS, mainly alpha,beta-unsaturated aldehydes, di-aldehydes, and keto-aldehydes, are due to their capacity to react with cellular constituents, forming advanced lipoxidation end-products (ALEs). Specific carbonyls, such as alpha-dicarbonyls, may be aldehydic or ketonic (or both) , and are very potent Maillard reaction intermediates, yielding advanced glycation end products (AGEs) as well as advanced lipoxidation end products (ALEs). the role of AKR1B3 in regulating advanced glycosylation end products and advanced lipoxidation end products; Genetic deficiency of Ar significantly ameliorated development of key endpoints linked with early diabetic nephropathy in vivo. a Y48F/H110F double mutant of AKR1B3 completely lost PGDS activity and showed only 2.9% of PGFS activity

Advanced Lipoxidation End-products (ALEs) are modified proteins that can act as pathogenic factors in several chronic diseases. Several molecular mechanisms have so far been considered to explain (2013). Advanced glycoxidation and lipoxidation end products (AGEs and ALEs): an overview of their mechanisms of formation. Free Radical Research: Vol. 47, No. sup1, pp. 3-27. Advanced Lipoxidation End Products (ALEs) are glycated lipids and fats. They’re basically the same thing with minor differences. AGEs are thought to promote aging, inflammation, and worsen many diseases such as diabetes, atherosclerosis, chronic kidney disease, and Alzheimer’s [i] . A review from 2000 summarized additional identifications of different advanced lipoxidation end-products found in atherosclerotic lesions, including MDA-lysine , HNE-lysine , , and levuglandin E2 , which were analysed by both immunohistochemical and chemical techniques . lipid peroxidation products is remarkable. We will focus in this contribution on lipid peroxidation products with α,β-unsaturated keto/aldehyde moiety as reactivity site and engage in covalent interaction with proteins to exert their biological roles. Examples of such lipoxidation-derived electrophiles are compiled in …
