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.

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

There is considerable evidence that chronic moderate-to-high alcohol consumption increases blood pressure. The mechanisms by which this occurs are not clear. Alcohol consumption can induce oxidative stress and cytochrome P450 (CYP450) isoforms that are associated with oxidative stress and may
