Nitro-Oleic Acid Regulates Endothelin Signaling in Human Endothelial Cells.

Nrf2-dependent and -independent responses to nitro-fatty acids in human endothelial cells: identification of heat shock response as the major pathway activated by nitro-oleic acid.

Electrophilic fatty acid derivatives, including nitrolinoleic acid and nitro-oleic acid (OA-NO(2)), can mediate anti-inflammatory and pro-survival signaling reactions. The transcription factor Nrf2, activated by electrophilic fatty acids, suppresses redox-sensitive pro-inflammatory gene expression and protects against vascular endothelial oxidative injury. It was therefore postulated that activ...

All-trans Retinoic Acid Regulates the Balance of Treg-Th17 Cells through ERK and P38 Signaling Pathway

Fatty acid transduction of nitric oxide signaling: nitrolinoleic acid potently activates endothelial heme oxygenase 1 expression.

Nitroalkenes are a class of cell signaling mediators generated by NO and fatty acid-dependent redox reactions. Nitrated fatty acids such as 10- and 12-nitro-9,12-octadecadienoic acid (nitrolinoleic acid, LNO(2)) exhibit pluripotent antiinflammatory cell signaling properties. Heme oxygenase 1 (HO-1) is up-regulated as an adaptive response to inflammatory mediators and oxidative stress. LNO(2) (1...

Protection of nitro-fatty acid against kidney diseases.

Nitrated derivatives of unsaturated fatty acids are endogenously formed under oxidative and nitrative stress condition and are defined as electrophilic fatty acids containing a nitro group to a carbon-carbon double bond. Among the most studied nitro derivatives of unsaturated fatty acids are nitro-oleic acid (OA-NO2) and nitro-linoleic acid (LNO2). These products exhibit novel protective action...

Nitro-fatty acids reduce atherosclerosis in apolipoprotein E-deficient mice.

OBJECTIVE Inflammatory processes and foam cell formation are key determinants in the initiation and progression of atherosclerosis. Electrophilic nitro-fatty acids, byproducts of nitric oxide- and nitrite-dependent redox reactions of unsaturated fatty acids, exhibit antiinflammatory signaling actions in inflammatory and vascular cell model systems. The in vivo action of nitro-fatty acids in chr...
