Enhancing antitumor effects in pancreatic cancer cells by combined use of COX-2 and 5-LOX inhibitors

Cyclooxygenase (COX)-2 and lipoxygenase (LOX)-5 are involved in carcinogenesis of pancreatic cancer. COX-2 inhibitor celecoxib displays inhibitory effects in pancreatic cancer cell growth. Recently, it has been reported that COX-2 inhibitor may not be able to suppress pancreatic tumor growth in vivo and its application is further limited by untoward side effects. The present study provides evidence that combined use of celecoxib and 5-LOX...
