“…The principles have mostly commonly been explored with linoleic acid and have focused on the formation of 4-hydroxy-2-nonenal (HNE), owing to the fact that it is one of the most abundantly formed lipid peroxidation products and has interesting biological effects [8,28,29]. The mechanisms are (i) reduction of hydroperoxide to an alkoxyl radical in the presence of a transition metal followed by β-scission; (ii) Hock rearrangement of a hydroperoxide and migration of a C-C to a C-O bond and cleavage; (iii) cyclization to form a dioxetane and subsequent cleavage.…”

The process of lipid oxidation generates a diverse array of small aldehydes and carbonyl-containing compounds, which may occur in free form or esterified within phospholipids and cholesterol esters. These aldehydes mostly result from fragmentation of fatty acyl chains following radical oxidation, and the products can be subdivided into alkanals, alkenals (usually D,β-unsaturated), γ-substituted alkenals and bis-aldehydes.Isolevuglandins are non-fragmented di-carbonyl compounds derived from H 2 -isoprostanes, and oxidation of the ω-3-fatty acid docosahexenoic acid yield analogous 22 carbon neuroketals. Non-radical oxidation by hypochlorous acid can generate D-chlorofatty aldehydes from plasmenyl phospholipids. Most of these compounds are reactive and have generally been considered as toxic products of a deleterious process. The reactivity is especially high for the D,β-unsaturated alkenals, such as acrolein and crotonaldehyde, and for γ-substituted alkenals, of which 4-hydroxy-2-nonenal and 4-oxo-2-nonenal are best Page | 2 known. Nevertheless, in recent years several previously neglected aldehydes have been investigated and also found to have significant reactivity and biological effects; notable examples are 4-hydroxy-2-hexenal and 4-hydroxy-dodecadienal. This has led to substantial interest in the biological effects of all of these lipid oxidation products and their roles in disease, including proposals that HNE is a second messenger or signalling molecule.However, it is becoming clear that many of the effects elicited by these compounds relate to their propensity for forming adducts with nucleophilic groups on proteins, DNA and specific phospholipids. This emphasizes the need for good analytical methods, not just for free lipid oxidation products but also for the resulting adducts with biomolecules. The most informative methods are those utilizing HPLC separations and mass spectrometry, although analysis of the wide variety of possible adducts is very challenging. Nevertheless, evidence for the occurrence of lipid-derived aldehyde adducts in biological and clinical samples is building, and offers an exciting area of future research.

“…The physiological concentration of HNE in the plasma is reportedly from 0.3-0.7 μM (164,165) but its concentration can reach as high 10 μM or more in plasma membrane under conditions of oxidative stress (166,167). While HNE is therefore considered as a biomarker of oxidative stress (167,168), it is also implicated in various oxidative stress-related diseases, including atherosclerosis (169), neurodegenerative diseases (170), and fibrosis (171).…”

During the past several years, major advances have been made in understanding how reactive oxygen species (ROS) and nitrogen species (RNS) participate in signal transduction. Identification of the specific targets and the chemical reactions involved still remains to be resolved with many of the signaling pathways in which the involvement of reactive species has been determined. Our understanding is that ROS and RNS have second messenger roles. While cysteine residues in the thiolate (ionized) form found in several classes of signaling proteins can be specific targets for reaction with H 2 O 2 and RNS, better understanding of the chemistry, particularly kinetics, suggests that for many signaling events in which ROS and RNS participate, enzymatic catalysis is more likely to be involved than non-enzymatic reaction. Due to increased interest in how oxidation products, particularly lipid peroxidation products, also are involved with signaling, a review of signaling by 4-hydroxy-2-nonenal (HNE) is included. This article focuses on the chemistry of signaling by ROS, RNS, and HNE and will describe reactions with selected target proteins as representatives of the mechanisms rather attempt to comprehensively review the many signaling pathways in which the reactive species are involved.

This has been markedly helped by identification of the specific targets in signaling pathways. In previous reviews, we defined how ROS, H 2 O 2 in particular,

“…A number of recent reviews covering studies on the role of HNE in the modulation of signaling processes are also available [2][3][4][17][18][19][20][21][22][23][24]. Most of these reviews have focused on the role of HNE in inducing apoptosis, regulation of the expression of genes, and its interactions with target proteins including the components of various signaling cascades.…”

Self-regulatory role of 4-hydroxynonenal in signaling for stress-induced programmed cell death

Within the last two decades, 4-hydroxynonenal has emerged as an important second messenger involved in the regulation of various cellular processes. Our recent studies suggest that HNE can induce apoptosis in various cells through the death receptor Fas (CD95)-mediated extrinsic pathway as well as through the p53-dependent intrinsic pathway. Interestingly, through its interaction with the nuclear protein Daxx, HNE can self-limit its apoptotic role by translocating Daxx to cytoplasm where it binds to Fas and inhibits Fas-mediated apoptosis. In this paper, after briefly describing recent studies on various biological activities of HNE, based on its interactions with Fas, Daxx, and p53, we speculate on possible mechanisms through which HNE may affect a multitude of cellular processes and draw a parallel between signaling roles of H 2 O 2 and HNE.
