Is cyclooxygenase-1 involved in neuroinflammation? [PDF]

open access: yesJ Neurosci Res, 2021
AbstractPurpose: Reactive microglia are an important hallmark of neuroinflammation. Reactive microglia release various inflammatory mediators, such as cytokines, chemokines, and prostaglandins, which are produced by enzymes like cyclooxygenases (COX).

Endothelial cyclooxygenase-1 paradoxically drives local vasoconstriction and atherogenesis despite underpinning prostacyclin generation. [PDF]

open access: yesSci Adv, 2021
Endothelial cyclooxygenase-1–derived prostanoids, including prostacyclin, have clear cardioprotective roles associated with their anti-thrombotic potential but have also been suggested to have paradoxical pathological activities within arteries.

Cyclooxygenase-1 (COX-1) and COX-1 Inhibitors in Cancer: A Review of Oncology and Medicinal Chemistry Literature [PDF]

open access: yesPharmaceuticals, 2018
Prostaglandins and thromboxane are lipid signaling molecules deriving from arachidonic acid by the action of the cyclooxygenase isoenzymes COX-1 and COX-2.

Expression of Cyclooxygenase-1 and Cyclooxygenase-2 in Human Breast Cancer [PDF]

open access: bronzeJNCI: Journal of the National Cancer Institute, 1998
Numerous studies have demonstrated that the levels of prostaglandins are greater in various cancers, including breast cancer and colon cancer, than in normal tissues. In particular, the inducible form of cyclooxygenase (COX), the rate-limiting enzyme in prostaglandin biosynthesis, is overexpressed in colon tumors.

The role of cyclooxygenase-1 and cyclooxygenase-2 in lipopolysaccharide and interleukin-1 stimulated enterocyte prostanoid formation [PDF]

open access: yesMediators of Inflammation, 1998
Lipopolysaccharide is an inflammatory agent and interleukin-1 is a cytokine. Their pro-inflammatory effects may be mediated by prostanoids produced by inducible cyclooxygenase-2.

Expression of mRNA for cyclooxygenase‐1 and cyclooxygenase‐2 in human tissues [PDF]

open access: yesFEBS Letters, 1993
The rate‐limiting step in the formation of prostanoids is the conversion of arachidonic acid to prostaglandin H2 by cyclooxygenase, also known as prostaglandin G/H synthase/cyclooxygenase. Two forms of cyclooxygenase have been characterized: a ubiquitously expressed form (COX‐1) and a recently described second form (COX‐2) inducible by various factors ...

Molecular Identification of Cytosolic Prostaglandin E2 Synthase That Is Functionally Coupled with Cyclooxygenase-1 in Immediate Prostaglandin E2Biosynthesis [PDF]

open access: hybridJournal of Biological Chemistry, 2000
Here we report the molecular identification of cytosolic glutathione (GSH)-dependent prostaglandin (PG) E2 synthase (cPGES), a terminal enzyme of the cyclooxygenase (COX)-1-mediated PGE2 biosynthetic pathway. GSH-dependent PGES activity in the cytosol of

Impact of Wines and Wine Constituents on Cyclooxygenase-1, Cyclooxygenase-2, and 5-Lipoxygenase Catalytic Activity

open access: yesMediators of Inflammation, 2014
Cyclooxygenases and lipoxygenases are proinflammatory enzymes; the former affects platelet aggregation, vasoconstriction, vasodilatation and later the development of atherosclerosis.

Regulated Spatial Distribution of Cyclooxygenases and Lipoxygenases in Crohn's Ulcer [PDF]

open access: yesMediators of Inflammation, 2006
Background and Aims. Arachidonic acid metabolism actively participates in the initiation, climaxing, and resolution phases of inflammation, and its close connection with inflammatory bowel diseases has been only recently discovered.

Pharmacological analysis of cyclooxygenase-1 in inflammation [PDF]

open access: yesProceedings of the National Academy of Sciences, 1998
The enzymes cyclooxygenase-1 and cyclooxygenase-2 (COX-1 and COX-2) catalyze the conversion of arachidonic acid to prostaglandin (PG) H2, the precursor of PGs and thromboxane. These lipid mediators play important roles in inflammation and pain and in normal physiological functions.
