Cyclooxygenase-dependent signalling: molecular events and consequences Versteeg HH; van Bergen en Henegouwen PM; van Deventer SJ; Peppelenbosch MPFEBS Lett 1999[Feb]; 445 (1): 1-5Non-steroidal anti-inflammatory drugs (NSAIDs) currently attract large interest. Next to pain relief, NSAIDs have important anti-thrombotic and anti-oncogenic effects. NSAIDs exert their action by inhibition of cyclooxygenase, the enzyme responsible for the production of prostanoids. Prostanoid signal transduction is still poorly understood, but it has become clear that these inflammatory lipids influence cellular physiology at three different levels: (1) activation of a 7 x transmembrane receptor coupled to heterotrimeric G proteins, (2) the inhibition of inflammation by activating corticosteroid-like receptors, (3) participation in receptor protein tyrosine kinase signal transduction. In this review prostanoid signalling at these three different levels will be reviewed and the relevance in (patho)physiological processes will be evaluated.|*Signal Transduction[MESH]|Humans[MESH]|Prostaglandin-Endoperoxide Synthases/*metabolism[MESH]|Prostaglandins/biosynthesis[MESH]|Receptors, Prostaglandin/metabolism[MESH]|Second Messenger Systems[MESH] |
