cyclooxygenase-2 (cox-2) has a pivotal role in the pathogenesis of the lung cancer. it is known that cox-2 negatively regulates the activity of a number of tumor suppressors, including p53. consequently, inhibition of cox-2 signaling is anticipated to be a promising approach to stabilize p53 functionality. in this regard, we investigated the effect of cox-2 signaling blockade on p53 and cox-2 e...

Despite the important role of both cyclooxygenase (COX) isoforms (i.e. COX-1 and COX-2) in maintenance of hypersensitivity following peripheral nerve injury, their role in the development of neuropathic pain is not clear. The present study was undertaken to determine the effect of COX inhibitors to address the potential role of COX isozymes in the development of neuropathic pain in rats after c...

Non-steroidal anti-inflammatory drugs (NSAIDs) are the competitive inhibitors of cyclooxygenase (COX), the enzyme which mediates the bioconversion of arachidonic acid to inflammatory prostaglandins (PGs). Their use is associated with the side effects such as gastrointestinal and renal toxicity. The therapeutic anti-inflammatory action of NSAIDs is produced by the inhibition of COX-2, while the ...

Background: Radiation-induced basal cell carcinoma (BCC) can be multiple, large, and recurring, which complicates its treatment in some cases. According to reports on the role of cyclooxygenase 2 (COX2) inhibitors in the treatment or prevention of non-melanoma skin cancers and considering the fact that COX2 expression has not been evaluated in radiation-in...

IN a subset of patients with asthma, nonsteroidal antiinflammatory drugs (NSAIDs) that inhibit both cyclooxygenase 1 (COX-1) and cyclooxygenase 2 (COX-2) can precipitate dangerous asthmatic attacks. It has been proposed that in these patients, the attacks are triggered by inhibition of COX-1 and not COX-2, and that the use of highly selective COX-2 inhibitors may be safe in asthmatic patients, ...
