Biochem/physiol Actions

20-Hydroxy-(5Z,8Z,11Z,14Z)-eicosatetraenoic acid (20-HETE) is an arachidonic acid metabolite via cytochrome P4504A, that is an activator of the Ras/MAP (microtubule-associated protein) pathway. 20-HETE acid is a predominant arachidonic acid present in the kidney. It is involved in the regulation of sodium, potassium and chloride transport in the renal tubules. 20-HETE is often excreted in urine in the form of glucuronide conjugate and sometimes as free acids. Increased urine 20-HETE is observed during pregnancy in rats.

Postmenopausal period has been associated to different symptoms such as hot flashes, vulvovaginal atrophy, hypoactive sexual desire disorder (HSDD) and others. Clinical studies have described postmenopausal women presenting HSDD can benefit from the association of testosterone to conventional hormonal therapy.

Astrocytes express neurotransmitter receptors that serve as sensors of synaptic activity and initiate signals leading to activity-dependent local vasodilation and increases in blood flow. We previously showed that arteriolar vasodilation produced by activation of cortical astrocytes is dependent on endothelial

20-HETE (20-hydroxyeicosatetraenoic acid), a vasoconstrictor metabolite of arachidonic acid formed through the action of CYP4A (cytochrome P450-4A) in vascular smooth muscle cells, has been implicated in the development of hypertension and vascular dysfunction. There have been a number of reports

Cortical spreading depression (CSD) is associated with release of arachidonic acid, impaired neurovascular coupling, and reduced cerebral blood flow (CBF), caused by cortical vasoconstriction. We tested the hypothesis that the released arachidonic acid is metabolized by the cytochrome P450 enzyme
