Vascular Cytochrome P450 Enzymes: Physiology and Pathophysiology

Cytochrome P450 epoxygenases and the soluble epoxide hydrolase are enzymes that regulate the cellular content of bioactive epoxides such as the epoxyeicosatrienoic acids derived from arachidonic acid. Epoxyeicosatrienoic acids are recognized as lipid mediators that participate in vascular signaling processes such as the acute regulation of vascular tone and the processes of inflammation and angiogenesis.
