Polymorphisms in human soluble epoxide hydrolase.
Human soluble epoxide hydrolase (hsEH) metabolizes a variety of epoxides to the corresponding vicinal diols. Arachidonic and linoleic acid epoxides are thought to be endogenous substrates for hsEH. Enzyme activity in humans shows high interindividual variation (e.g., 500-fold in liver) suggesting the existence of regulatory and/or structural gene polymorphisms. We resequenced each of the 19 exo...
متن کاملMeasurement of soluble epoxide hydrolase (sEH) activity.
The human soluble epoxide hydrolase (sEH; EC 3.3.3.2) is the product of the EXPH2 gene. The sEH catalyzes the addition of a water molecule to an epoxide, resulting in the corresponding diol. Early work suggested a role of sEH in detoxifying a wide array of xenobiotic epoxides; however, recent findings clearly implicate the sEH in the regulation of blood pressure, pain, and inflammation through ...
متن کاملOxetane Substrates of Human Microsomal Epoxide Hydrolase.
Oxetanyl building blocks are increasingly used in drug discovery because of the improved drug-like properties they confer on drug candidates, yet little is currently known about their biotransformation. A series of oxetane-containing analogs was studied and we provide the first direct evidence of oxetane hydrolysis by human recombinant microsomal epoxide hydrolase (mEH). Incubations with human ...
متن کاملEpoxide hydrolase activity in isolated peroxisomes of mouse liver.
Using trans-stilbene oxide as substrate, the subcellular distribution of epoxide hydrolase was investigated in livers from DBA/2 mice. The highest specific activities were found in cytosolic and light mitochondrial fractions. Isopycnic subfractionation of the light mitochondrial fraction showed that the organelle-bound trans-stilbene oxide hydrolase is localized in peroxisomes.
متن کاملIncreased cholesterol epoxide hydrolase activity in clofibrate-fed animals.
Cholesterol epoxide hydrolase (mCE) is a microsomal enzyme that hydrolyzes cholesterol-5,6-epoxides (CE) to cholestanetriol (CT). In the present study, hepatic mCE activity was measured in mice pretreated with several different xenobiotics known to induce a variety of hepatic drug-metabolizing enzymes. Only the phenoxyacetate hypolipidemics (clofibrate and ciprofibrate, included in the diet for...
