Research Abstract

We revealed that cytosolic prostaglandin E synthase(cPGES/p23) which isomerizes PGH2 to PGE2, promotes the expression of 15-hydroxyPG dehydrogenase(15-PGDH), which catalyzes the inactivating conversion of the PGE2 15-OH to a 15-keto group. This result suggests that the PGE2-inactivating pathway is controlled by the PGE2 biosynthetic enzyme, cPGES/p23.
