Does COX-2 promote inflammation?
COX-2 is a key mediator of inflammatory pathways and its elevated expression has been found in several other human cancers as well. The relation between inflammation and cancer in general is well documented. Several recent studies on KSHV and EBV have pointed to the role of COX-2 in virus mediated tumorigenesis.
Is COX-2 an inflammatory mediator?
Cyclooxygenase-2 (COX-2) is an enzyme that plays a key role in inflammatory processes. Classically, this enzyme is upregulated in inflammatory situations and is responsible for the generation of prostaglandins (PGs) from arachidonic acid (AA).
What is the benefit of COX-2?
Advantages of COX-2 inhibitors COX-2 selective inhibitors were developed to reduce the risk of gastrointestinal ulceration caused by non-selective NSAIDs. By selectively inhibiting COX-2 they reduced the risk of upper gastrointestinal bleeding associated with other NSAIDs.
What is the role of COX during inflammation?
In the first, cyclooxygenase (COX) initiates the formation of prostaglandins and thromboxane. Inhibition of COX is one mechanism by which nonsteroidal anti-inflammatory drugs (NSAIDs) exert their potent analgesic and anti-inflammatory effects.
What does COX do in inflammation?
Cyclooxygenase (COX) is an enzyme that helps create prostaglandins. Prostaglandins are natural chemicals in the body that are vital to creating inflammation. High levels of prostaglandins are present in areas of the body that become inflamed.
How COX-2 is produced?
Cox-2 is expressed by inflammatory cells, such as macrophages, and can be induced by TNF and EGF. The prostaglandins and eicosanoids produced can have a major role in the development of human cancers but the role is not as firmly established in PCa.
Are COX-2 inhibitors better than NSAIDs?
COX-2-selective inhibitors are associated with a significant reduction in gastroduodenal damage compared with traditional NSAIDs. Proton pump inhibitors (PPI) are probably the best agents for healing and prevention of NSAID-induced ulcers.
