Common_Name8-iso-13,14-dihydro-15-keto-PGF2a
Description8-iso-13,14-dihydro-15-keto-PGF2a is an isoprostane. Isoprostanes are a family of prostaglandin (PG) isomers generated by free radical-catalysed peroxidation and then rearrangement of arachidonic acid. In addition, isoprostanes can be produced by cyclo-oxygenase (COX) dependent pathways. Several cell types have been shown to release increased levels of the F2 isoprostane, 8-iso PGF2alpha, when stimulated with inflammatory mediators or subjected to oxidative stress in vitro. Furthermore, 8-iso PGF2alpha levels are elevated in rats in vivo when prooxidant conditions are induced experimentally. Similarly, elevated isoprostane production has been demonstrated in clinical conditions characterized by oxidant stress including diabetes, alcoholism, paraquat poisoning, myocardial reperfusion, critical illness, pre-eclampsia and smoking. Consequently, the measurement of 8-iso PGF2alpha in plasma and urine has been proposed as a relevant and convenient method to monitor oxidant stress in man. (PMID: 11309241)
