abstractText | Cyclooxygenase-2 (Cox-2) modulates many normal functions, and appears to play a role in a wide variety of pathophysiologic conditions. Cox-2 gene expression is induced in many different cell types, in response to many distinct stimuli. We generated a conditional knockout mouse in which critical exons of the Cox-2 gene are flanked with loxP sites. Cox-2(flox/flox) mice appear normal and are fertile. Recombination at the loxP sites, loss of Cox-2 protein expression, and prevention of induced PGE2 accumulation are observed in Cox-2(flox/flox) mouse embryo fibroblasts following infection with an adenovirus expressing CRE recombinase. In vivo recombination at the Cox-2(flox) allele was demonstrated in the liver of Cox-2(flox/flox) mice following intravenous injection of adenovirus expressing CRE recombinase. Spatially and temporally restricted elimination of the Cox-2 gene in Cox-2(flox/flox) conditional knockout mice should provide a valuable tool to analyze the cell type-specific role of Cox-2 in many disease models. |
