Soluble epoxide hydrolase (sEH) inhibitors have been demonstrated to have cardiovascular protective actions. This hydrolase enzyme converts fatty acid epoxides to their corresponding diols, and this conversion can alter the biologic activity of these metabolites. We hypothesized that
Soluble epoxide hydrolase (sEH) metabolizes epoxyeicosatrienoic acids (EETs) to dihydroxyeicosatrienoic acids. EETs are formed from arachidonic acid during myocardial ischemia and play a protective role against ischemic cell death. Deletion of sEH has been shown to be protective against myocardial
Inhibition and deletion of soluble epoxide hydrolase (sEH) has been suggested to ameliorate infarction in experimental ischemic stroke possibly via vasoactive epoxyeicosatrienoic acids. However, it is unknown whether the neuroprotective mechanisms involve alteration of post-ischemic neuronal
Multiple players are involved in the highly complex pathophysiologic responses after stroke. Therefore, therapeutic approaches that target multiple cellular elements of the neurovascular unit in the damage cascade hold considerable promise for the treatment of stroke. Cytochrome P450 (CYP)
Ischemic stroke triggers inflammatory responses and oxidative stress in the brain, and microglia polarization affects the degree of neuroinflammation. It has been reported that the inhibition of soluble epoxide hydrolase (sEH) activity protects brain tissue. However, the Kawasaki disease (KD) is the leading cause of acquired heart disease in pediatric patients in developed countries. Coronary artery aneurysms and myocardial infarction may occur if the disease remains untreated. An estimated 10-20% of KD patients do not respond to intravenous gamma globulin (IVIG),
The P450 eicosanoids epoxyeicosatrienoic acids (EETs) are produced in brain and perform important biological functions, including protection from ischemic injury. The beneficial effect of EETs, however, is limited by their metabolism via soluble epoxide hydrolase (sEH). We tested the hypothesis that
It is generally understood that continuing neuroinflammation after ischemic stroke can exacerbate the brain damage. During the inflammatory hematogenous recruitment process, the monocytes and macrophages are activated into proinflammatory M1 and anti-inflammatory M2 cell types. Inhibition of soluble
Previously, we demonstrated (17) that 11,12- and 14,15-epoxyeicosatrienoic acids (EETs) produce marked reductions in myocardial infarct size. Although it is assumed that this cardioprotective effect of the EETs is due to a specific interaction with a membrane-bound receptor, no evidence has
Arachidonic acid is metabolized to a number of bioactive eicosanoid molecules by several enzymes, including enzymes of the COX, lipoxygenase and cytochrome P450 (CYP) monooxygenase pathways. Inhibition of the CYP omega-hydroxylase pathway, stimulation of the CYP-epoxygenase pathway and
Inhibition of soluble epoxide hydrolase (SEH), the enzyme responsible for degradation of vasoactive epoxides, protects against cerebral ischemia in rats. However, the molecular and biological mechanisms that confer protection in normotension and hypertension remain unclear. Here we show that 6 weeks
