Phosphatidylinositol 3 kinase pathway and 4-hydroxy-2-nonenal-induced oxidative injury in the RPE.

PURPOSE 4-Hydroxy-2-nonenal (4-HNE) is a major lipid peroxidation product in the retina and the retinal pigment epithelium. The purpose of the present study was to investigate how NF-E2-related factor-2 (Nrf2) and phosphatidylinositol 3 (PI3K) pathways affect the responses of cultured human retinal pigment epithelial (RPE) cells to 4-HNE. METHODS Cultured ARPE-19 cells were treated with diffe...

1 4 - hydroxy - 2 - nonenal : a critical target in oxidative stress ? 1

20 In this perspective, we summarize and discuss critical advancements in the study of 421 hydroxy-2-nonenal (4-HNE) as it relates to diseases and clinical complications either caused or 22 exacerbated by oxidative stress. Since its identification in 1980, 4-HNE has been extensively 23 studied with an emphasis on its formation, its role in pathology, and its targets. As a reactive 24 aldehyde, ...

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 ...

4-hydroxy-2-nonenal Induces Endothelial Cell Injury via Pkcδ and Biphasic Jnk Activation

4-Hydroxy-2-nonenal (4-HNE), a major product generated during oxidative stress, exhibits cytotoxic effects; however, the mechanisms of 4-HNE-induced endothelial cell injury are not well defined. To explore this issue, we examined how 4-HNE damages human umbilical vein endothelial cells (HUVECs) and found that 4-HNE induced biphasic activation of c-Jun N-terminal kinase (JNK). Both preand post-t...

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...
