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...
متن کامل20-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...
متن کامل20-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...
متن کامل20-hydroxyeicosatetraenoic acid causes endothelial dysfunction via eNOS uncoupling.
Nitric oxide (NO), generated from L-arginine by endothelial nitric oxide synthase (eNOS), is a key endothelial-derived factor whose bioavailability is essential to the normal function of the endothelium. Endothelium dysfunction is characterized by loss of NO bioavailability because of either reduced formation or accelerated degradation of NO. We have recently reported that overexpression of vas...
متن کاملRenal 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 ...
