Abstract
Acetaminophen is a widely used analgesic and antipyretic, which can cause liver injury after an overdose. Although a controversial topic for some time, solid evidence for a critical role of oxidative and nitrosative stress has emerged during the last two decades. This review will discuss the cellular sources, amplification mechanisms, and the consequences of the excessive formation of reactive oxygen and nitrogen species in the clinically relevant mouse model of acetaminophen hepatotoxicity. This new mechanistic insight contributes to the better understanding of the mechanism of action of N-acetylcysteine, the only clinically approved antidote. In addition, it provides the rationale for the development of new antidotes that target the formation or metabolism of mitochondrial superoxide.
期刊介绍：
The aims and scope of Current Opinion in Toxicology is to systematically provide the reader with timely and provocative views and opinions of the highest qualified and recognized experts on current advances in selected topics within the field of toxicology. The goal is that Current Opinion in Toxicology will be an invaluable source of information and perspective for researchers, teachers, managers and administrators, policy makers and students. Division of the subject into sections: For this purpose, the scope of Toxicology is divided into six selected high impact themed sections, each of which is reviewed once a year: Mechanistic Toxicology, Metabolic Toxicology, Risk assessment in Toxicology, Genomic Toxicology, Systems Toxicology, Translational Toxicology.
