Nrf2 Ameliorates Atrial Fibrosis During Antithrombotic Therapy for Atrial Fibrillation by Modulating CYP2C9 Activity.
Abstract: Anticoagulant therapy can significantly reduce the incidence of stroke and peripheral embolism events in patients with atrial fibrillation (AF). Although warfarin is widely used as an anticoagulant drug, a wrong dose can lead to increased risks of bleeding or blood clots. The aim of this study was to assess whether nuclear factor-erythroid-2-related factor 2 (Nrf2) can improve the efficacy of warfarin through the regulation of cytochrome P450 family 2 subfamily C member 9 (CYP2C9) using a rat model of AF. Results showed that AF significantly reduced Nrf2 in myocardial tissue of sham-operated rats. Furthermore, Nrf2 overexpression effectively reduced AF-induced atrial fibrosis by reducing collagen in the left atrium, inhibiting the expression of the fibrosis-related genes collagen I and transforming growth factor-β1 in rats with AF. Nrf2 overexpression can activate CYP2C9, decrease the serum concentration of warfarin, and decrease prothrombin time and international normalized ratio in AF rats. In this article, Nrf2 overexpression protects against fibrosis, increased survival in AF rats, and activated CYP2C9 expression, thus broadening the therapeutic range of warfarin in AF rats.
期刊介绍：
Journal of Cardiovascular Pharmacology is a peer reviewed, multidisciplinary journal that publishes original articles and pertinent review articles on basic and clinical aspects of cardiovascular pharmacology. The Journal encourages submission in all aspects of cardiovascular pharmacology/medicine including, but not limited to: stroke, kidney disease, lipid disorders, diabetes, systemic and pulmonary hypertension, cancer angiogenesis, neural and hormonal control of the circulation, sepsis, neurodegenerative diseases with a vascular component, cardiac and vascular remodeling, heart failure, angina, anticoagulants/antiplatelet agents, drugs/agents that affect vascular smooth muscle, and arrhythmias.
Appropriate subjects include new drug development and evaluation, physiological and pharmacological bases of drug action, metabolism, drug interactions and side effects, application of drugs to gain novel insights into physiology or pathological conditions, clinical results with new and established agents, and novel methods. The focus is on pharmacology in its broadest applications, incorporating not only traditional approaches, but new approaches to the development of pharmacological agents and the prevention and treatment of cardiovascular diseases. Please note that JCVP does not publish work based on biological extracts of mixed and uncertain chemical composition or unknown concentration.
