Effect of a Selective Cyclooxygenase-2 Inhibitor, Nimesulide, on the Growth of Lung Tumors and Their Expression of Cyclooxygenase-2 and Peroxisome Proliferator- Activated Receptor-γ

Abstract

Nimesulide (1500 ppm) induced growth inhibition of A549 lung tumors is associated with the reduction of intratumor PGE(2) levels but without affecting the expression of COX-2. Nimesulide-induced enhancement of the expression of PPAR-gamma may also contribute to its antitumor effect, which needs to be further investigated.
