Abstract excerpt
Prostaglandin endoperoxide H synthase 2 (PGHS-2) catalyzes the rate-limiting steps in the synthesis of PGE(2). It is substantially but transiently induced in human orbital fibroblasts treated with IL-1beta. In this study, we report that the induction of PGHS-2 by IL-1beta is dramatically enhanced and prolonged when Jak2 signaling is abrogated, either with the specific inhibitor AG490 or by transiently...
