Figure 1From: Non-steroid anti-inflammatory drugs, prostaglandins, and cancerBiosynthesis and activities of prostaglandins and sites of NSAIDs actions. Cyclooxygenase metabolism of arachidonic acid can lead to the formation of prostaglandins that exert a variety of biological activities through their respective cognate receptors. The involvement of prostanoid receptors in cancer is also shown. Abbreviations: COX, cyclooxygenase; PG, prostaglandin; PLA2, phospholipase 2; TXA2, thromboxane A2; TP, thromboxane A2 receptor; EP, prostaglandin E2 receptor; IP, prostacyclin (PGI2) receptor; DP, prostaglandin D2 receptor; FP, prostaglandin F2 receptor; NSAIDs, non-steroid anti-inflammatory drugs.Back to article page
