Prostaglandin E synthase 2 is an enzyme that in humans is encoded by the PTGES2 gene.[1][2]

The protein encoded by this gene is a membrane-associated prostaglandin E synthase, which catalyzes the conversion of prostaglandin H2 to prostaglandin E2. This protein also has been shown to activate the transcription regulated by an interferon-gamma gamma-interferon-activated transcription element (GATE).[2]

Model organisms

Model organisms have been used in the study of PTGES2 function. A conditional knockout mouse line, called Ptges2tm1a(EUCOMM)Wtsi[7][8] was generated as part of the International Knockout Mouse Consortium program — a high-throughput mutagenesis project to generate and distribute animal models of disease to interested scientists — at the Wellcome Trust Sanger Institute.[9][10][11]

Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion.[5][12] Twenty two tests were carried out on mutant mice, but no significant abnormalities were observed.[5]

Clinical significance

The excess production of prostaglandin E 2 is known to contribute to inflammatory diseases which includes rheumatoid arthritis, atherosclerosis, and cancer.[13][14] As such, pharmacological inhibition of prostaglandin E 2 production by synthetic minor prenylated chalcones and flavonoids has potential therapeutic viability.[13] It has been shown that the synthesis of prostaglandin E 2 in the endothelial cells of the brain is important for inflammation-induced fever.[15] Additionally, investigators have observed elevations in cell doubling rates for several cancer cell types in the presence of prostaglandin E 2 –producing cell lines.[16]
