High impact information on 13-Hydroperoxyoctadecadienoic acid

• We determined the uptake and metabolism of unoxidized (linoleic or oleic acid) and oxidized linoleic acid (13-hydroperoxyoctadecadienoic acid, 13-HPODE) by endothelial cells, smooth muscle cells, and macrophages [1].
• Derivatives of diphenyl-N-hydroxyureas, 4-hydroxybenzofurans and 5-hydroxydihydrobenzofurans all stimulated the 5-lipoxygenase-mediated destruction of 13-hydroperoxyoctadecadienoic acid (13-HPOD) [2].
• Regulation of monocyte chemoattractant protein-1 by the oxidized lipid, 13-hydroperoxyoctadecadienoic acid, in vascular smooth muscle cells via nuclear factor-kappa B (NF-kappa B) [3].
• Upon reaction of egg PE with 13-hydroperoxyoctadecadienoic acid or other oxidized polyunsaturated fatty acids followed by phospholipase D-mediated hydrolysis, the formation of N-(hexanoyl)ethanolamine (HEEA), a head group of HEPE, was confirmed by isotope dilution liquid chromatography/tandem mass spectrometry [4].
• The obtained antibody recognized not only 15-HPETE-modified bovine serum albumin (BSA) but also 13-hydroperoxyoctadecadienoic acid (13-HPODE)-modified BSA [5].

Anatomical context of 13-Hydroperoxyoctadecadienoic acid

• The effects of 13-hydroperoxyoctadecadienoic acid (13-HPODE) on the cytosolic or microsomal acyl-CoA hydrolase (ACH) activity in rabbit kidney medulla and on the ACH-mediated prostaglandin (PG) formation from arachidonoyl-CoA (AA-CoA) were examined [6].
• Effect of 13-hydroperoxyoctadecadienoic acid on 15-hydroxy prostaglandin dehydrogenase activity in rabbit kidney cortex [7].
• Inhibition of 15-hydroxy prostaglandin dehydrogenase activity in rabbit gastric antral mucosa by 13-hydroperoxyoctadecadienoic acid [8].
• The effect of 13-hydroperoxyoctadecadienoic acid (13-HPODE) on the synthesis of prostaglandins (PGs) was examined in rabbit kidney medulla microsomes [9].

Associations of 13-Hydroperoxyoctadecadienoic acid with other chemical compounds

• The exclusive production of 13-hydroperoxyoctadecadienoic acid derivatives of dilinoleoyl phosphatidylcholine at pH 7.5 and 10 may result from the blockage of the carboxylic end of the fatty acid [10].

Gene context of 13-Hydroperoxyoctadecadienoic acid

• OBJECTIVE: Several proatherogenic agents including oxidized LDL and its major component, 13-hydroperoxyoctadecadienoic acid (13-HPODE), upregulate heme oxygenase-1 (HO-1) [11].
• In the presence of 13-hydroperoxyoctadecadienoic acid, the enzymatic catalysis of cyclooxygenase and 12-lipoxygenase was significantly increased in the GSH-depleted cells [12].
• The lipoxygenase product of linoleic acid, 13-hydroperoxyoctadecadienoic acid (13-HPODE), is a significant component of oxidized LDL and has been shown to be present in atherosclerotic lesions [13].

Analytical, diagnostic and therapeutic context of 13-Hydroperoxyoctadecadienoic acid

• Titration of the protein with 13-HPOD (13-hydroperoxyoctadecadienoic acid) generates a strong multicomponent EPR signal in the g' approximately 6 region, a yellow color associated with an increased absorption between 310 and 450 nm (epsilon 330nm = 2400 M-1 cm-1), and a 17% decrease in the intrinsic protein fluorescence [14].
• The effect of dopamine-melanin (DA-melanin), synthetic model of neuromelanin, on the stability of 13-hydroperoxyoctadecadienoic acid (13-HPODE) has been investigated using a reverse-phase high-performance liquid chromatography (HPLC) with UV detection [15].
