Prostaglandin synthase 2 gene disruption causes severe renal pathology in the mouse.

The prostaglandin endoperoxide H synthase isoform 2, cyclooxygenase 2 (COX-2), is induced at high levels in migratory and other responding cells by pro-inflammatory stimuli. COX-2 is generally considered to be a mediator of inflammation. Its isoform, COX-1, is constitutively expressed in most tissues and is thought to mediate "housekeeping" functions.
