Prostaglandin-endoperoxide synthase 1

cyclooxygenase, COX-1, Cyclooxygenase 1
Prostaglandin-endoperoxide synthase (PTGS), also known as cyclooxygenase, is the key enzyme in prostaglandin biosynthesis, and acts both as a dioxygenase and as a peroxidase. There are two isozymes of PTGS: a constitutive PTGS1 and an inducible PTGS2, which differ in their regulation of expression and tissue distribution. This gene encodes PTGS1, which regulates angiogenesis in endothelial cells, and is inhibited by nonsteroidal anti-inflammatory drugs such as aspirin. PTGS1 is thought to be involved in cell-cell signaling and maintaining tissue homeostasis. Alternative splicing of this gene generates two transcript variants. The expression of these two transcripts is differentially regulated by relevant cytokines and growth factors. [provided by RefSeq, Jul 2008] (from NCBI)

Papers on cyclooxygenase
Does aberrant expression of cyclooxygenase-2 and prostaglandin-E2 receptor genes lead to abortion in Chlamydia trachomatis infected women.
Rastogi et al., New Delhi, India. In J Matern Fetal Neonatal Med, 27 Apr 2015
OBJECTIVE: The aim of the study was to characterize the expression of Cyclooxygenase-2 (COX-2) and Prostaglandin-E2 (PGE2) genes in spontaneously aborted tissues from women infected with Chlamydia trachomatis.

Acetaminophen Old Drug, New Issues.
Khan et al., Chapel Hill, United States. In J Endod, 27 Mar 2015
Finally, emerging evidence suggests that although the predominant mechanism by which acetaminophen exerts its therapeutic effect is by inhibition of cyclooxygenase, multiple other mechanisms also contribute to its analgesic effect.
Blocking PGE2-induced tumour repopulation abrogates bladder cancer chemoresistance.
Chan et al., Houston, United States. In Nature, 08 Feb 2015
In vivo administration of the cyclooxygenase-2 (COX2) inhibitor celecoxib effectively abolishes a PGE2- and COX2-mediated wound response gene signature, and attenuates progressive manifestation of chemoresistance in xenograft tumours, including primary xenografts derived from a patient who was resistant to chemotherapy.
New insights into the use of currently available non-steroidal anti-inflammatory drugs.
Patrignani et al., Erlangen, Germany. In J Pain Res, Dec 2014
Non-steroidal anti-inflammatory drugs (NSAIDs), which act via inhibition of the cyclooxygenase (COX) isozymes, were discovered more than 100 years ago.
The effects and possible mechanisms of puerarin to treat endometriosis model rats.
Yu et al., Shanghai, China. In Evid Based Complement Alternat Med, Dec 2014
Puerarin could reduce the levels of E2 and PGE2 and prevent the growth of ectopic endometrium tissues by inhibiting the expression of aromatase cytochrome P450 (p450arom) and cyclooxygenase-2 (cox-2); puerarin could adjust the anabolism of E2 by upregulating the expression of 17β-hydroxysteroid-2 (17β-hsd-2) and downregulating the expression of 17β-hydroxysteroid-1 (17β-hsd-1) of the ectopic endometrium tissues; puerarin could increase the expression of ERβ and improve the inflammatory microenvironment of EMT model rats.
Induction of COX-2-PGE2 synthesis by activation of the MAPK/ERK pathway contributes to neuronal death triggered by TDP-43-depleted microglia.
Wang et al., Suzhou, China. In Cell Death Dis, Dec 2014
In this study, we show that depletion of TDP-43 in microglia, but not in astrocytes, strikingly upregulates cyclooxygenase-2 (COX-2) expression and prostaglandin E2 (PGE2) production through the activation of MAPK/ERK signaling and initiates neurotoxicity.

Felipo, Valencia, Spain. In Nat Rev Neurosci, 2013
New therapeutic strategies acting on specific targets in the brain (phosphodiesterase 5, type A GABA receptors, cyclooxygenase and mitogen-activated protein kinase p38) have been shown to restore cognitive and motor function in animal models of chronic HE, and NMDA receptor antagonists have been shown to increase survival in acute liver failure.
Δ9-THC-caused synaptic and memory impairments are mediated through COX-2 signaling.
Chen et al., New Orleans, United States. In Cell, 2013
Here, we show that synaptic and cognitive impairments following repeated exposure to Δ(9)-tetrahydrocannabinol (Δ(9)-THC) are associated with the induction of cyclooxygenase-2 (COX-2), an inducible enzyme that converts arachidonic acid to prostanoids in the brain.

Induction of COX-2 enzyme and down-regulation of COX-1 expression by lipopolysaccharide (LPS) control prostaglandin E2 production in astrocytes.
Planas et al., Barcelona, Spain. In J Biol Chem, 2012
Astrocytes respond to lipopolysaccharide by a COX-2-dependent production of prostanoids, mainly vasoactive PGE(2), and suggest that the coordinated down-regulation of COX-1 facilitates PGE(2) production after TLR-4 activation.
