| pubmed-article:11675186 | pubmed:abstractText | Cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) enzymes catalyze the initial step in the formation of prostaglandins, which have a role in the regulation of circulation and in inflammatory reactions. As hypoxia is reported to stimulate the expression of COX-2, we have investigated the effects of bypass circulation and cardioplegic arrest on the expression COX-1 and COX-2 in the myocardium of porcine hearts. | lld:pubmed |
