Metabolite Identification
Common Name14,15-DiHETrE
Description14,15-DiHETrE is a Cytochrome P450 (P450) eicosanoid. Eicosanoids generated from arachidonic acid metabolism by cytochrome P450 (P450) enzymes are important autocrine and paracrine factors that have diverse biological functions. P450 eicosanoids are involved in the regulation of vascular tone, renal tubular transport, cardiac contractility, cellular proliferation, and inflammation. Regulation of P450 eicosanoid levels is determined by many factors, including the induction or repression of the P450 enzymes responsible for their formation. Fibrate drugs are part of a diverse group of compounds known as peroxisome proliferators, which also include herbicides and phthalate ester plasticizers. Peroxisome proliferators act via peroxisome proliferator-activated receptor (PPAR ). This receptor is a member of the PPAR nuclear receptor family that also consists of the PPAR and PPAR isoforms. PPAR is mainly expressed in the heart, liver, and kidney, whereas the expression of PPAR is predominantly in the adipose tissue. The biological role of PPAR as a lipid sensor has been well established. 14,15-DiHETrE is a potent activators of PPAR and PPAR, shown to induce the binding of PPAR to a peroxisome proliferator response element (PPRE). Furthermore, 14,15-DiHETrE behaves like peroxisome proliferators in that is able to alter apoA-I and apoA-II mRNA expression. 14,15-DiHETrE is the most potent PPARalpha activator in a COS-7 cell expression system producing a 12-fold increase in PPARalpha-mediated luciferase activity.

General function:
Involved in catalytic activity
Specific function:
Bifunctional enzyme. The C-terminal domain has epoxide hydrolase activity and acts on epoxides (alkene oxides, oxiranes) and arene oxides. Plays a role in xenobiotic metabolism by degrading potentially toxic epoxides. Also determines steady-state levels of physiological mediators. The N-terminal domain has lipid phosphatase activity, with the highest activity towards threo-9,10-phosphonooxy-hydroxy-octadecanoic acid, followed by erythro-9,10-phosphonooxy-hydroxy-octadecanoic acid, 12-phosphonooxy-octadec-9Z-enoic acid, 12-phosphonooxy-octadec-9E-enoic acid, and p-nitrophenyl phospate.
