Lipid Peroxidation: Production, Metabolism, and Signaling Mechanisms of Malondialdehyde and 4-Hydroxy-2-Nonenal

Lipid peroxidation can be described generally as a process under which oxidants such as free radicals attack lipids containing carbon-carbon double bond(s), especially polyunsaturated fatty acids (PUFAs). Over the last four decades, an extensive body of literature regarding lipid peroxidation has shown its important role in cell biology and human health. Since the early 1970s, the total publish...

Synaptosomal Toxicity and Nucleophilic Targets of 4-Hydroxy-2-Nonenal

4-Hydroxy-2-nonenal (HNE) is an aldehyde by-product of lipid peroxidation that is presumed to play a primary role in certain neuropathogenic states (e.g., Alzheimer disease, spinal cord trauma). Although the molecular mechanism of neurotoxicity is unknown, proteomic analyses (e.g., tandem mass spectrometry) have demonstrated that this soft electrophile preferentially forms Michael-type adducts ...

Effect of 4-Hydroxy-2-Nonenal Modification on -Synuclein Aggregation

Several observations have implicated oxidative stress and aggregation of the presynaptic protein-synuclein in the pathogenesis of PD.-Synuclein has been shown to have affinity for unsaturated fatty acids and membranes enriched in PUFAs, which are especially sensitive to oxidation under conditions of oxidative stress. One of the most important products of lipid oxidation is 4-hydroxynonenal (H...

Novel role of 4-hydroxy-2-nonenal in AIFm2-mediated mitochondrial stress signaling.

Cardiovascular complications are major side effects of many anticancer drugs. Accumulated evidence indicates that oxidative stress in mitochondria plays an important role in cardiac injury, but how mitochondrial redox mechanisms are involved in cardiac dysfunction remains unclear. Here, we demonstrate that 4-hydroxy-2-nonenal (HNE) activates the translocation of the mitochondrial apoptosis indu...

4-Hydroxy-2-nonenal Induces Apoptosis by Inhibiting AKT Signaling in Human Osteosarcoma Cells

The onset of lipid peroxidation within cellular membranes is associated with changes in their physiochemical properties and enzymatic dysfunction of the membrane environment. There are increasing bodies of evidence indicating that aldehydic molecules generated endogenously during the process of lipid peroxidation are causally involved in most of the pathophysiological effects associated with ox...
