Albumin redirects platelet eicosanoid metabolism toward 12(S)-hydroxyeicosatetraenoic acid.

Journal of Lipid Research, 1989
Albumin is a major determinant of eicosanoid formation, affecting autacoids important in cell-cell interactions. We delineated three mechanisms by which albumin controlled platelet eicosanoid formation: 1) Albumin diverted free arachidonate toward 12 ...

Oxidative modification of human lipoproteins by lipoxygenases of different positional specificities

Journal of Lipid Research, 1994
Cellular lipoxygenases have been implicated in foam cell formation during the early stages of atherogenesis. We studied the interaction of lipoxygenases of different positional specificities with human lipoproteins and found that the arachidonate 15 ...

Abnormalities of Sphingolipids Metabolic Pathways in the Pathogenesis of Psoriasis

Metabolites, 2023
Psoriasis is immune-mediated skin disorder affecting thousands of people. Sphingolipids (SLs) are bioactive molecules present in the epidermis, involved in the following cellular processes: proliferation, differentiation, and apoptosis of keratinocytes ...

Evidence for cytokine regulation of cholesterol metabolism in herpesvirus-infected arterial cells by the lipoxygenase pathway.

Journal of Lipid Research, 1990
Cytokines such as tumor necrosis factor (TNF), interleukin-1 (IL-1), and gamma-interferon (IF) are produced by activated hematopoietic cells. They possess antiviral activity and have other biological activities such as induction of cell proliferation and

RNAseq analysis of treatment-dependent signaling changes during inflammation in a mouse cutaneous wound healing model

BMC Genomics, 2021
Background Despite proven therapeutic effects in inflammatory conditions, the specific mechanisms of phytochemical therapies are not well understood. The transcriptome effects of Traumeel (Tr14), a multicomponent natural product, and diclofenac, a non ...

Ascorbic acid enhances the inhibitory effect of aspirin on neuronal cyclooxygenase-2-mediated prostaglandin E2 production. [PDF]

, 2006
Inhibition of neuronal cyclooxygenase-2 (COX-2) and hence prostaglandin E2 (PGE2) synthesis by non-steroidal anti-inflammatory drugs has been suggested to protect neuronal cells in a variety of pathophysiological situations including Alzheimer's disease ...

5 S,15 S-Dihydroperoxyeicosatetraenoic Acid (5,15-diHpETE) as a Lipoxin Intermediate: Reactivity and Kinetics with Human Leukocyte 5-Lipoxygenase, Platelet 12-Lipoxygenase, and Reticulocyte 15-Lipoxygenase-1. [PDF]

, 2018
The reaction of 5 S,15 S-dihydroperoxyeicosatetraenoic acid (5,15-diHpETE) with human 5-lipoxygenase (LOX), human platelet 12-LOX, and human reticulocyte 15-LOX-1 was investigated to determine the reactivity and relative rates of producing lipoxins (LXs).

12-HETE is an Endogenous Modulator of BLT2 Triggering Vascular Degeneration, Dissection, and Rupture. [PDF]

Adv Sci (Weinh)
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.
