title: Microsomal prostaglandin E synthase-1 and 5-lipoxygenase: potential drug targets in cancer.
abstract: There is strong evidence for a role of prostaglandin (PG)E(2) in cancer cell proliferation and tumour development. In PGE(2) biosynthesis, cyclooxygenases (COX-1/2) convert arachidonic acid to PGH(2), which can be isomerized to PGE(2) by PGE synthases, including microsomal PGE synthase-1 (MPGES-1). Data describing genetic deletions of MPGES-1 are reviewed. The results suggest that MPGES-1 is an alternative therapeutic target for cancer cells and tumours that express this enzyme. Several compounds that target COX-2 or MPGES-1 also inhibit 5-lipoxygenase. This may be advantageous for treatment of some forms of cancer.
