Prostaglandin H Synthase (PGHS) is a bi-functional enzyme with a cyclooxygenase (COX) activity and a functionally linked peroxidase (POX) activity that exists in two isoforms (COX-1, COX-2). Non-steroidal anti-inflammatory drugs (NSAIDs), including the selective COX-2 inhibitors, block COX activity while leaving POX activity unscathed. Recently, some selective COX-2 inhibitors were withdrawn from the market due to elevated cardiovascular risk in placebo-controlled trials. Mice deficient for PGHS2 were developed in 1995 and through numerous subsequent studies have revealed significant roles in renal development, ductus arteriosus patency/closure, skin carcinogenesis and cardiovascular function. In this short review, we compare a novel genetic COX-2 selective inhibition mouse model with the originally described COX-2 null mice in these different physiological functions.
