15056798-6	2004	Inhibition of mitogen-activated protein kinase kinase (MAPKK) and p38 MAPK using PD98059 (20 microM) and SB202190 (5 microM), respectively, attenuated the elevation of COX-2 protein induced by arsenite, whereas physiological concentrations of three COX-2 inhibitors (e.g., NS-398, piroxicam, and aspirin) reduced arsenite-stimulated DNA synthesis.
