Cyclooxygenase-2 and carcinogenesis
Biochimica et Biophysica Acta (BBA) - Reviews on Cancer, 2000Numerous investigations have shown that COX-2 is a participant in the pathway of colon carcinogenesis, especially when mutation of the APC tumor suppressor is the initiating event. Moreover, it seems that the amount of COX-2 is important, since there is a correlation between its level of expression and the size of the tumors and their propensity to ...

Cyclooxygenase-2 and atherosclerosis
Current Opinion in Lipidology, 2002Cyclooxygenase regulates the production of eicosanoids, which modulate physiologic processes in the vessel wall contributing to atherosclerosis and thrombosis, including platelet aggregation, control of vascular tone, and the local inflammatory response.

European Journal of Pharmacology, 1998
The anti-inflammatory activity of drugs more selective for cyclooxgenase isoform inhibition (cyclooxygenase 1, cyclooxygenase 2), were compared in rat carrageenin-induced pleurisy. Suppression of inflammation by cyclooxygenase 2-selective inhibitors, NS-398 (N-[-2-cyclohexyloxy]-4-nitrophenyl methanesulphonamide) and nimesulide (4-nitro-2-phenoxy ...

Cyclooxygenase 2 and the kidney
Current Opinion in Nephrology and Hypertension, 2001Cyclooxygenase metabolizes arachidonic acid to a family of bioactive fatty acids designated prostaglandins. Two isoforms of cyclooxygenase exist, designated COX1 and COX2. These isoforms are expressed in distinct but important areas of the kidney. COX1 predominates in vascular smooth muscle and collecting ducts, whereas COX2 predominates in the macula ...

Current Opinion in Internal Medicine, 2006
The purpose of this review is to summarize new information regarding the use of selective inhibitors of the cyclooxygenase-2 enzyme, emphasizing recent developments regarding cardiovascular risk.Selective cyclooxygenase-2 inhibitors are as effective as nonselective nonsteroidal antiinflammatory drugs in relieving pain and inflammation but are ...

Annual Review of Pharmacology and Toxicology, 1998
▪ Abstract Cyclooxygenase (COX), first purified in 1976 and cloned in 1988, is the key enzyme in the synthesis of prostaglandins (PGs) from arachidonic acid. In 1991, several laboratories identified a product from a second gene with COX activity and called it COX-2.

Expression of Cyclooxygenase-1 and Cyclooxygenase-2 in the human prostate
Urology, 2000To determine the cell-specific expression of the two major isoforms of cyclooxygenase (COX-1 and COX-2) in human noncancerous and cancerous prostatic tissues.Thirty-one specimens of prostate carcinoma (CaP) and 10 specimens of benign prostatic hyperplasia (BPH) were stained with mouse antihuman COX-1 and COX-2 monoclonal antibodies.

Cyclooxygenase-2 Inhibition and Coagulation
Journal of Cardiovascular Pharmacology, 2006Selective inhibitors of cyclooxygenase-2 (COX-2) have come under scrutiny because of a possibly increased thrombotic risk observed in retrospective studies and comparatively small cancer trials. Indeed, inhibition of COX-2 may favor a prothrombotic environment by suppressing endothelial prostacyclin synthesis while leaving COX-1-dependent platelet ...

Publisher Summary This chapter deals with aspects of the discovery and development of Cyclooxygenase-2 (Cox-2) inhibitors, which, in the case of rofecoxib, resulted from efforts that were initiated in July of 1992 and culminated in the launch of the drug in the United States in June of 1999. Nonsteroidal antiinflammatory drugs (NSAIDs) have long been

Current Pharmaceutical Design, 2003
In mammalian cells, eicosanoid biosynthesis is usually initiated by the activation of phospholipase A(2) and the release of arachidonic acid from membrane phospholipids in response to the interaction of a stimulus with a receptor on the cell surface. Arachidonic acid is subsequently transformed by the enzyme cyclooxygenase (COX) to prostaglandins (PGs)
