Epoxyeicosatrienoic acid

Epoxyeicosatrienoic acid (EETs) are signaling molecules produced within the body from arachidonic acid by the action of cytochrome P450 enzymes. They are part of the eicosanoid family of fatty acids, which play a role in inflammation, immunity, and other bodily functions.

Production and Metabolism

EETs are produced from arachidonic acid, a polyunsaturated fatty acid, by the action of cytochrome P450 enzymes. These enzymes are found in many tissues throughout the body, including the liver, kidneys, and heart. Once produced, EETs can be further metabolized by soluble epoxide hydrolase (sEH), which converts them into less active dihydroxyeicosatrienoic acids (DHETs).

Biological Functions

EETs have a wide range of biological functions. They are involved in the regulation of vascular tone, inflammation, and blood clotting. They also play a role in the protection of the heart during ischemic events, such as a heart attack. In addition, EETs have been shown to promote the growth of new blood vessels, a process known as angiogenesis.

Clinical Significance

Due to their role in inflammation and vascular regulation, EETs have been implicated in a number of diseases, including hypertension, atherosclerosis, and diabetes. Inhibitors of sEH, which increase the levels of EETs, are currently being investigated as potential treatments for these conditions.
