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
Review on emu products for use as complementary and alternative medicine.
Naidu et al., Hyderābād, India. In Nutrition, 31 Jan 2015
Previous studies suggest that the fatty acids of the ω-9, ω-6, and ω-3 series, which are present in emu oil, may act on cyclooxygenase, lipoxygenase, and lipoxin pathways to bring about its anti-inflammatory and other beneficial actions.
