Abstract

We investigated the effects of tranilast on inducible cyclooxygenase (COX2)-mediated prostaglandin E2 (PGE2) production and enzyme induction in interleukin-lbeta (IL-1beta)-stimulated cultured dermal fibroblasts. IL-1beta enhanced PGE2 production in cultured fibroblasts. Tranilast did not affect constitutive cyclooxygenase (COX1) or COX2 activity in non-stimulated or IL-lbeta-stimulated fibroblasts. However, the COX2 expression induced by IL-1beta was inhibited by tranilast. This result, that IL-1beta-induced COX2 expression was suppressed by tranilast, was confirmed by immunohistochemical analysis. Thus, it is possible for tranilast to regulate PGE2 production by inhibiting COX2 induction.
