The possible beneficial effects of omega-3 fatty acid-rich diets in pathological states involving inflammation, hypertension, blood clotting, heart attacks and other cardiac diseases, strokes, brain seizures, pain perception, acute kidney injury, and cancer are suggested to result, at least in part, from the conversion of dietary EPA and DHA to EEQs and EPAs, respectively, and the cited subsequent actions of these metabolites. 1029:
produced significant reductions in systolic blood pressure and increased peripheral arteriole blood flow and reactivity in patients at high to intermediate risk for cardiovascular events; an EPA/DHA-rich diet also reduced the risk while high serum levels of DHA and EPA were associated with a low risk of neovascular age-related macular degeneration. Since such diets lead to large increases in the serum and urine levels of EPAs, EEQs, and the dihydroxy metabolites of these epoxides but relatively little or no increases in EETs or

The EET-forming CYP epoxygenases often metabolize EPA to EEQs (as well as DHA to EDPs) at rates that exceed their rates in metabolizing arachidonic acid to EETs; that is, EPA (and DHA) appear to be preferred over arachidonic acid as substrates for many CYP epoxygenases. 1000:(EETs). In comparison to the many activities attributed to the EETs in animal model studies, a limited set of studies indicate that EEQs (and EPAs) mimic EETs in their abilities to dilate arterioles, reduce hypertension, inhibit inflammation (the anti-inflammatory actions of EEQ are less potent than those of the EETs) and thereby reduce occlusion of arteries to protect the heart and prevent 797:(EDPs) isomers. In general, the same epoxygenases that accomplish these metabolic conversions also metabolize the omega-6 fatty acid, EPA, to 10 epoxide isomers, the EEQs. These epoxygenases fall into several subfamilies including the cytochrome P4501A (i.e.CYP1A), CYP2B, CYP2C, CYP2E, and CYP2J subfamilies, and within the CYP3A subfamily, CYP3A4. In humans, 941:
dihydroxyeicosatetraenoic acids (diHETEs). The omega-3 fatty acid epoxides, EEQs and EPAs, appear to be preferred over EETs as substates for sEH. sEH converts 17,18-EEQ isomers to 17,18-dihydroxy-eicosatrienoic acid isomers (17,18-diHETEs), 14,15-EEQ isomers to 14,15-diHETE isomers, 11,12-EEQ isomers

properties in relieving certain types of pain. Often, the EEQs (and EPAs) exhibit greater potency and/or effectiveness than EET in these actions. In human studies potentially relevant to one or more of these activities, consumption of long chain omega-3 fatty acid (i.e. EPA- and DHA-rich) diet

In direct contrast to the EETs which have stimulating effects in the following activities (see 969:(mEH or epoxide hydrolase 2 ) can metabolize EEQs to their dihydroxy products but is regarded as not contributing significantly to EEQ inactivation in vivo except possibly in rare tissues where the sEH level is exceptionally low while the mEH level is high. 588:. These epoxygenases can metabolize EPA to as many as 10 epoxides that differ in the site and/or stereoisomer of the epoxide formed; however, the formed EEQs, while differing in potency, often have similar bioactivities and are commonly considered together. 917:. These tissues are known to metabolize arachidonic acid to EETs; it has been shown or is presumed that they also metabolize EPA to EEQs. Note, however, that the CYP epoxygenases, similar to essentially all CYP450 enzymes, are involved in the metabolism of 2014:
