Involvement of leukotriene pathway in the pathogenesis of ischemia-reperfusion injury and septic and non-septic shock. [PDF]
The 5-lipoxygenase (5-LO) pathway is responsible for the production of leukotrienes (LTs), inflammatory lipid mediators which play a role in innate immunity. More recently, a pivotal role of LTs in ischemia-reperfusion and shock injury has been suggested.

Intake and metabolism of omega-3 and omega-6 polyunsaturated fatty acids: nutritional implications for cardiometabolic diseases [PDF]
Prospective observational studies support the use of long-chain omega-3 polyunsaturated fatty acids (PUFAs) in the primary prevention of atherosclerotic cardiovascular disease; however, randomised controlled trials, have often reported neutral findings ...

The cytokines interleukin-8 (IL-8) and granulocyte-macrophage colony-stimulating factor (GM-CSF) enhanced the extracellular release of arachidonate metabolites from ionophore-stimulated neutrophils by 145 ± 10% (mean ± S.E.M., n = 13) and 182 ± 11% (n ...

Expression of mRNA for phospholipase A(2), cyclooxygenases, and lipoxygenases in cultured human umbilical vascular endothelial and smooth muscle cells and in biopsies from umbilical arteries and veins [PDF]
Arachidonic acid (AA) is released by phospholipase A(2) (PLA(2)) and then converted into vasoactive and inflammatory eicosanoids by cyclooxygenases (COX) and lipoxygenases (LOX).

Influence of leukotriene gene polymorphisms on chronic rhinosinusitis
Background Chronic rhinosinusitis (CRS) is increasingly viewed as an inflammatory condition of the sinonasal mucosa interacting with bacteria and/or fungi. However, factors conferring susceptibility to disease remain unknown.

Decreased ovarian reserve, dysregulation of mitochondrial biogenesis, and increased lipid peroxidation in female mouse offspring exposed to an obesogenic maternal diet. [PDF]
Maternal diet during pregnancy influences the later life reproductive potential of female offspring. We investigate the molecular mechanisms underlying the depletion of ovarian follicular reserve in young adult females following exposure to obesogenic ...

Arachidonic acid and calcium metabolism in rnelittin stimulated neutrophils
Melittin, the predominant fraction of bee venom proteins, was studied in an experimental model of human neutrophil granulocytes to reveal its influence on eicosanoid release, metabolism and receptor function in relation to intracellular calcium ...

12-HETE is an Endogenous Modulator of BLT2 Triggering Vascular Degeneration, Dissection, and Rupture. [PDF]
In thoracic aortic dissection (TAD), elevated levels of the arachidonic acid metabolite 12‐HETE, produced by macrophage‐specific 12/15‐lipoxygenase (12/15‐LOX), bind to the BLT2 receptor on vascular cells. This activates the NOX‐1/ROS/NF‐κB signaling pathway, leading to IL‐6 release.

The chronic myeloid leukemia stem cell: stemming the tide of persistence [PDF]
Chronic myeloid leukaemia (CML) is caused by the acquisition of the tyrosine kinase BCR-ABL1 in a haemopoietic stem cell (HSC), transforming it into a leukaemic stem cell (LSC) that self-renews, proliferates and differentiates to give rise to a ...

Convergent Oxygenation of Arachidonic Acid by 5-Lipoxygenase and Cyclooxygenase-2 [PDF]
5-Lipoxygenase and cyclooxygenase-2 (COX-2) initiate the biosynthesis of distinct families of mediators from arachidonic acid (leukotrienes and prostaglandins, respectively) and are each the target of anti-inflammatory medications. Here we show that the product of 5-lipoxygenase, 5S-hydroxyeicosatetraenoic acid, is selectively and efficiently triply ...
