Type:

Cyclooxygenase-2 (COX-2) is an enzyme that plays a critical role in the conversion of arachidonic acid to prostaglandins, which are lipid compounds involved in various physiological processes, including inflammation, pain, and fever. COX-2 is an inducible enzyme, meaning its expression is typically low in normal tissues but can be upregulated in response to inflammatory stimuli, growth factors, and certain oncogenic signals.
-Cyclooxygenase-2 (COX-2), the rate-limiting enzyme in prostaglandin biosynthesis, plays a key role in inflammation and circulatory homeostasis.
-COX-2 is an inducible enzyme that is upregulated in response to pro-inflammatory signals, including cytokines (e.g., IL-1β, TNF-α) and growth factors.

COX-2 is often overexpressed in various tumors, including colorectal, breast, lung, and prostate cancers.
The prostaglandins produced by COX-2, particularly prostaglandin E2 (PGE2), have several effects that can facilitate cancer progression:
Cell Proliferation: PGE2 can promote the proliferation of cancer cells by activating signaling pathways such as the PI3K/Akt and MAPK pathways.
Nonselective NSAIDs, such as aspirin and ibuprofen, inhibit both COX-1 and COX-2. Epidemiological studies have suggested that regular use of NSAIDs may reduce the risk of certain cancers, particularly colorectal cancer.
Drugs specifically targeting COX-2, such as celecoxib, have been developed.

COX-2 and xanthine oxidase are ROS-producing pro-oxidant enzymes that contribute to inflammation. Elevated COX‑2 levels, often found in inflammatory conditions or certain types of cancers, can contribute to increased production of ROS.
