WebCyclo-oxygenase enzyme exists as two isoforms encoded by two separate genes. The two cyclo-oxygenases, cox-1 and cox-2, catalyze the same reaction: the formation of PGH 2 from AA. Their patterns of expression and regulation differ significantly. The cox-1 enzyme is constitutively expressed in most cell types, where it plays a housekeeping role.

The COX‐2 enzyme is known to be expressed when proinflammatory mediators are released. The use of COX-2 inhibitors such as celecoxib, rofecoxib, and valdecoxib has offered a better safety profile than classical NSAIDs, such as aspirin, ibuprofen, and indomethacin.
WebThere are two types of cyclooxygenase (COX) enzymes in your body, COX-1 and COX-2. Both enzymes make prostaglandins. Prostaglandins are hormone-like chemicals that … WebBecause cyclooxygenase (COX)-2 is expressed in atherosclerotic lesions and promotes inflammation, we tested the hypotheses that selective COX-2 inhibition would reduce early lesion formation in LDL receptor–deficient (LDLR −/−) mice and that macrophage COX-2 expression contributes to atherogenesis in LDLR −/− mice.
