... 2009 angiogenesis arachidonic acid cyclo-oxygenase (COX) endothelial cell prostanoid protease-activated receptor (PAR) The initial step in the formation of prostanoids by endothelial cells is the stimulus-induced liberation of AA (arachidonic acid) from the sn -2 position of membrane...

... arachidonic acid cascade. Upon chronic administration, lithium and carbamazepine decrease the binding activity of activator protein-2 and, in turn, the transcription, translation and activity of its arachidonic acid-selective calcium-dependent phospholipase A 2 gene product, whereas chronic valproic acid non...

...Jaffar Nourooz-Zadeh A large body of evidence indicates that measurement of F 2 -isoprostanes, specific prostaglandin F 2 -like compounds derived from the non-enzymatic peroxidation of arachidonic acid, is a reliable biomarker of oxidant stress in the human body. Since the discovery of F 2...

.... In the present review, we focus on exogenous and endogenous effects of NEFAs, including the polyunsaturated fatty acid, arachidonic acid (or its metabolites generated from cyclo-oxygenase activity), on β-cell metabolism, and have explored the outcomes with respect to β-cell insulin secretion. The effects...

...P.C. Calder The n –6 polyunsaturated fatty acid, arachidonic acid, is a precursor of prostaglandins, leukotrienes and related compounds that have important roles as mediators and regulators of inflammation. Consuming increased amounts of long chain n –3 polyunsaturated fatty acids (found in oily...

...-known, and apparently ubiquitous, store-operated mechanism, subsequent studies suggested that this was unlikely. It is now known that, in many cell types, a novel non-capacitative Ca 2+ -selective pathway whose activation is dependent on arachidonic acid is responsible, and the channels involved [ARC...

... Porphyridium cruentum are rich in arachidonic acid (AA, 20: 4 ω 6) and eicosapentaenoic acid (EPA, 20: 5 ω 3). A mutant of this alga, impaired of growth at suboptimal temperatures, was shown to have reduced levels of EPA and of the eukaryotic molecular species of monogalactosyldiacylglycerol (MGDG...
