5-Oxo-ETE (5-oxo-6,8,11,14-eicosatetraenoic acid) is an arachidonic acid metabolite formed by the oxidation of 5S-hydroxy-6,8,11,14-eicosatetraenoic acid (5-HETE) by 5-hydroxyeicosanoid dehydrogenase (5-HEDH), a microsomal enzyme found in leukocytes and platelets. 5-HEDH is highly selective for 5S-HETE, and displays little activity for other

The 5-lipoxygenase (5-LO) product 5-oxo-6,8,11,14-eicosatetraenoic acid (5-oxo-ETE), which is a potent chemoattractant for myeloid cells, is known to promote the survival of prostate cancer cells. In the present study, we found that PC3 prostate cancer cells and cell lines derived

Human polymorphonuclear leukocytes (PMNL) convert 6-trans isomers of leukotriene B4 (LTB4) to dihydro metabolites (Powell, W.S., and Gravelle, F. (1988) J. Biol. Chem. 263, 2170-2177). In the present study we investigated the mechanism for the initial step in the formation

The most frequent site of organ involvement in patients with any form of mastocytosis is the skin. Cutaneous expressions include urticaria pigmentosa, mastocytoma, diffuse and erythrodermic cutaneous mastocytosis, and telangiectasia macularis eruptiva perstans. The cutaneous lesions tend to appear early

5-Oxo-6E,8Z,11Z,14Z-eicosatetraenoic acid (5-oxo-ETE) is a metabolite of the 5-lipoxygenase (5-LO) product 5S-hydroxy-6E,8Z,11Z,14Z-eicosatetraenoic acid (5-HETE), formed by the microsomal enzyme 5-hydroxyeicosanoid dehydrogenase (5-HEDH). 5-oxo-ETE is a chemoattractant for neutrophils and eosinophils, both in vitro and in vivo.
