Role of 20-hydroxyeicosatetraenoic acid (20-HETE) in vascular system.

Cytochrome P450s (P450) metabolize arachidonic acid (AA) to hydroxyeicosatetraenoic acids (HETEs) and epoxyeicosatrienoic acids (EETs). Among these eicosanoids, 20-HETE is formed in a tissue and cell-specific fashion and plays an important role in the regulation of vascular tone in the brain, kidney, heart and splanchnic beds. 20-HETE is a potent vasoconstrictor produced in vascular smooth musc...

20-Hydroxyeicosatetraenoic Acid (20-HETE) Modulates Canonical Transient Receptor Potential-6 (TRPC6) Channels in Podocytes

The arachidonic acid metabolite 20-hydroxyeicosatetraenoic acid (20-HETE) regulates renal function, including changes in glomerular function evoked during tubuloglomerular feedback (TGF). This study describes the cellular actions of 20-HETE on cultured podocytes, assessed by whole-cell recordings from cultured podocytes combined with pharmacological and cell-biological manipulations of cells. B...

Renal 20-hydroxyeicosatetraenoic acid synthesis during pregnancy.

We examined whether renal 20-hydroxyeicosatetraenoic acid (20-HETE) synthesis is altered during gestation. Renal microsomal arachidonic acid omega-hydroxylase activity increased by 50 and 48% in rats on days 12 and 19 of gestation, respectively. Renal microvessel 20-HETE synthesis increased by 50 and 82% in rats on days 6 and 12 of gestation, respectively, and returned to control levels at day ...

Postmenopausal hypertension: role of 20-HETE.

Blood pressure (BP) increases after menopause. However, the mechanisms responsible have not been elucidated. In this study we tested the hypothesis that 20-hydroxyeicosatetraenoic acids (20-HETE), produced by cytochrome P-450 (CYP450) ω-hydroxylase, contributes to the hypertension in a model of postmenopausal hypertension, aged female spontaneously hypertensive rats (PMR). 1-Aminobenzotriazole,...

20-Hydroxyeicosatetraenoic acid involved in endothelial activation and thrombosis.

Endothelial cells play an important role in the process of coagulation and the function of platelets. We have previously reported that 20-hydroxyeicosatetraenoic acid (20-HETE), a metabolite of arachidonic acid, increased platelet aggregation and induced hemostasis. The purpose of the present study is to investigate whether 20-HETE-mediated endothelial activation has effect on the coagulation a...
