“…For example, overexpression of CYP2J2 in bovine aortic endothelial cells promotes cell proliferation, migration, and tube formation (39). COX-1 is constitutively expressed in most tissues, and therefore we might expect the formation of the 8,9-E-HET metabolites, because their formation by COX-1 was demonstrated in this study and others (17). The combination of COX-1 and COX-2 may lead to the highest levels of E-HETs formed, as we show EETs to be substrates for both enzymes.…”

“…Compared with 5,6-EET, which is metabolized by COX through the same mechanism as ARA to form an endoperoxide prostaglandin analog, the epoxide position in 8,9-EET blocks endoperoxide formation and instead forms monohydroxyl products on C-11 or C-15. These products are ct-8,9-E-11-HET or ct-8,9-E-15-HET (17). Kinetic plots for 8,9-EET with COX-1 and COX-2 are presented in Fig.…”

“…5,6-EET is converted to a prostaglandin analog, 5,6-epoxyprostaglandin (PG) E 1 , which functions as a renal vasodilator (12). 8(S),9(R)-EET can undergo only a partial cyclooxygenase reaction and is converted to 11-hydroxy-8,9-EET, a renal vasoconstrictor and mitogen for glomerular mesangial cells (73,178).…”
