| Abstract: | Eicosapentaenoic acid (EPA) metabolism into 3 series cyclooxygenase and 5 series lipoxygenase products was assessed in human and rabbit anterior uvea. Both tissues synthesized 3 series cyclooxygenase products such as delta17 6-keto-PGF1 (PGI3 metabolite), PGF3, PGE3, PGD3 and TxB3 (a stable product of TxA3) and lipoxygenase products 12-hydroxyeicosapentaenoic acid (HEPE), 5-HEPE and 5,12-diHEPE from 14C-EPA. EPA-derived cyclooxygenase product synthesis was considerably greater than the formation of lipoxygenase products from EPA in both tissues. |
