The effect of cadmium chloride (CdCl2) on the expression of E-cadherin was examined in bEnd.3 mousebrain endothelial cells. CdCl2 induced PGE2 release, which were blocked by non-steroidal antiinflamatorydrugs (NSAIDs) such as indomethacin and NS398 indicating the expression of COX-2 might contribute toPGE2 production. CdCl2 decreased the expression of E-cadherin, but not VE-cadherin at levels of mRNA andprotein. Reduced expression level of E-cadherin was restored by NSAIDs, which was reversed by the additionof PGE2. CdCl2-induced decrease of E-cadherin level was also recovered by antioxidants including N-acetyl-cyteine (NAC) and trolox. Together with previous report which showed CdCl2 induced COX-2 expression in acellular oxidative stress dependent manner, these data suggest that CdCl2 decreases E-cadherin expressionthrough induction of cellular oxidative stress and in turn COX-2 expression in brain endothelial cells.
