Cyclooxygenase-2 and kidney failure
Prostaglandins & Other Lipid Mediators, 2012Cyclooxygenase (COX)-dependent prostaglandins are necessary for normal kidney function. These prostaglandins are associated with inflammation, maintenance of sodium and water homeostasis, control of renin release, renal vasodilation, vasoconstriction attenuation, and prenatal renal development.

Cyclooxygenase-2 and Gastrointestinal Cancer
The Cancer Journal, 2004The cyclooxygenase (COX) enzymes (COX-1 and COX-2) are key enzymes of prostaglandin (PG) biosynthesis. Nonselective non-steroidal anti-inflammatory drugs (NSAIDs) inhibit the enzymatic activity of both COX-1 and COX-2. Selective COX-2 inhibitors have been developed that appear to have 50% less gastrointestinal toxicity than traditional nonselective ...

Cyclooxygenase-2 Expression in Chondrosarcoma
Oncology, 2004<i>Objective:</i> In recent years it has become evident that tissue cyclooxygenase-2 (COX-2) may play a role in carcinogenesis and tumor malignancy. There is now a mounting body of information that strongly implies that COX-2 inhibitors may be of some value in the management of patients with carcinomas, and most recently several similar ...

Cyclooxygenase-2 and Gastric Cancer
Cancer and Metastasis Reviews, 2011Gastric cancer remains a leading cause of cancer-related deaths worldwide, although its incidence has been steadily declining during recent decades. Expression of cyclooxygenase-2 (COX-2) is elevated in gastric carcinomas and in their precursor lesions.

Cyclooxygenase-2: A Therapeutic Target
Annual Review of Medicine, 2002▪ Abstract Cyclooxygenase (COX), also known as prostaglandin endoperoxide synthase, is the key enzyme required for the conversion of arachidonic acid to prostaglandins. Two COX isoforms have been identified, COX-1 and COX-2. In many situations, the COX-1 enzyme is produced constitutively (e.g., in gastric mucosa), whereas COX-2 is highly inducible (e.

Lung cancer and cyclooxygenase-2
The Annals of Thoracic Surgery, 2003Lung cancer is by far the leading cause of cancer-related death. Overall survival is poor and has not improved substantially over the last half century. It is clear that new approaches are needed and these should include prevention, screening for early detection, and novel treatments based on our understanding of the molecular biology of this disease ...

Mediation of Inflammation by Cyclooxygenase-2
1995Non-steroidal antiinflammatory drugs (NSAIDs) are commonly used for the treatment of inflammation, pain, and fever. Mechanistically, these compounds are believed to act via inhibition of the enzyme cyclooxygenase (COX), which catalyzes the conversion of arachidonic acid to the prostaglandins (PGs). Although commercially available NSAIDS are efficacious

[Cyclooxygenase-2 and cyclooxygenase-2 inhibitors in prostate cancer].
Zhonghua nan ke xue = National journal of andrology, 2009Cyclooxygenase-2 (Cox-2) is over-expressed in prostate cancer (PCa) and involved in its development and progression by facilitating inflammatory response, reducing cell apoptosis, increasing angiogenesis and damaging DNA oxidation. Selective Cox-2 inhibitors suppress PCa growth through various channels and therefore have a promising application value ...

Cyclooxygenase-2 selective inhibitors
Drugs of Today, 1999The identification of two cyclooxygenase (COX) enzymes has been a tremendous advance in understanding the role of prostaglandins in inflammation and the actions of nonsteroidal antiinflammatory drugs (NSAIDs). COX-1 activity appears to be related to "constitutive" or "housekeeping" functions in the gastric mucosa, kidney and platelets.

Cyclooxygenase-2 and Nitric Oxide
Journal of Cardiovascular Pharmacology, 2006Nitric oxide (NO) is a simple but pluripotent molecule that is mainly released from vascular endothelial cells where it is formed intracellularly by nitric oxide synthase from L-arginine in response to several stimuli, including shear stress or muscarinic receptor stimulation. NO stimulates guanylyl cyclase to form cyclic guanosine monophosphate, which
