Outline of Final Research Achievements |
Prostaglandin (PG) I2 synthase (PGIS) and Microsomal PGE synthase-1 (mPGES-1) are PG terminal synthases that function downstream of inducible COX-2 in the PGI2 and PGE2 biosynthetic pathway, respectively. In this study, we used mice deficient in PGIS and mPGES-1 to examine the importance of these PG terminal synthases in chemical carcinogen-induced carcinogenesis. This study indicate that mPGES-1-derived PGE2 and PGIS-derived PGI2 have opposing effects on chemical-induced colon carcinogenesis. Namely, the former PGE2 promotes and exacerbates chemical carcinogenesis, while the latter PGI2 suppresses it.
