Pharmacological Blockade Of The 20-Hete Receptor Lowers Blood Pressure And Alters Vascular Function In Mice With Vascular Smooth Muscle- Specific Overexpression Of Cyp4a12-20-Hete Synthase, Kevin Agostinucci

NYMC Student Theses and Dissertations

20-hydroxyeicosatetraenoic acid (20-HETE) is the ω-hydroxylation product of arachidonic acid catalyzed by CYP4A and 4F enzymes. 20-HETE is a vasoactive eicosanoid of the microcirculation exhibiting effects on both vascular smooth muscle cells (VSMC) and endothelial cells (EC). In VSMCs, 20-HETE’s bioactions include the stimulation of contraction, migration, and growth. In ECs, elevated 20-HETE is associated with reduced nitric oxide (NO) bioavailability, increased angiotensin converting enzyme (ACE) expression, and the promotion of inflammation. Recently in our laboratory, we identified GPR75 as a novel target of 20-HETE that promotes changes in blood pressure and vascular function. The aim of this study is …

A Case Of Amlodipine Overdose: Role Of High Dose Insulin Therapy, Kelvin Tran, Thinh Tang, Tarris Webber, Paul J. Kalekas, Quang T. Nguyen

Introduction: High dose insulin (HDI) therapy, defined as > 0.5 units/kg/hour, has been postulated to improve hemodynamics in both calcium channel blocker (CCB) and beta-blocker overdose. Proposed benefits of HDI include coronary and systemic vasodilation due to enhancement of nitric oxide synthase activity leading to improved contractility and decreased systemic vascular resistance, respectively. HDI also directly improves cardiac contractility by increasing glucose uptake and improving calcium handling within cardiac cells. We present a case of a patient with amlodipine overdose and her response to HDI therapy.
