Abstract:
Cyclooxygenase-2 (COX-2),the rate-limited enzyme that converts arachidonic acid into prostaglandin,has been found overexpression in many malignant tumors.The overexpression of COX-2 plays an important role in tumor genesis and progression and is closely associated with tumor prognosis,so this enzyme has become one of the potential therapeutic targets.Experimental studies reveal that selective COX-2 inhibitors can enhance the tumor radiosensitivity through a variety of molecular pathways and have a protective effect for normal tissues.Selective COX-2 inhibitors are promising radiotherapy modifiers and the underlying molecular mechanisms still need to be further studied.
