Once the existence of free radicals was proven, an avalanche of studies on free radical-mediated biological processes ensued. The study of reactive oxygen and nitrogen species (ROS and RNS) is center stage in biological free radical investigations. Written by a biochemist, Signaling Mechanisms of Oxygen and Nitrogen Free Radicals discusses the regulatory functions of ROS and RNS in physiological and pathophysiological states. An exploration of the main questions of signaling mechanisms of reactive oxygen and nitrogen species in enzymatic processes, this book draws attention to the chemical mechanisms of these reactions. It elucidates the differences between signaling functions and damaging effects of ROS and RNS in biological systems. The text also covers free radical signaling processes catalyzed by enzymes, producers of superoxide and nitric oxide that are able to use produced ROS and RNS as signaling species in their own catalytic processes. It then examines ROS and RNS signaling produced by mitochondrial enzymes. The author explores signaling functions of ROS and RNS in enzymatic heterolytic reactions, supplying important data on ROS and RNS signaling in the catalysis by the enzymes which do not produce free radicals by themselves. He provides information on signaling by reactive oxygen and nitrogen species in apoptosis and aging/senescence and concludes with coverage of mechanisms of free radical signaling in enzymatic processes. The book provides new understanding of signaling functions in living organisms related to cardiovascular processes, cancer, inflammation, hereditary diseases, and their regulation of physiological functions such as development, aging, and senescence. This information can support the development of new drugs and novel treatment methods.

Henry Jay Forman, Jon Fukuto and Martine Torres "Research is to see what everybody else has seen and to think what nobody else has thought. " -- Albert Szent-Gyorgyi Several years ago, one of us put together a book that dealt with various aspects of oxidative stress and introduced the concept of signal transduction by oxidants. Since then, the interest in the mechanisms by which reactive oxygen and nitrogen species (ROS/RNS) can modulate the cell’s response has tremendously grown, paralleling the intense efforts towards identifying new signaling pathways in which phosphorylation/dephosphorylation events take center stage. Evidence is now mounting that production of these species by the cells is required for their function from growth to apoptosis and numerous signaling pathways have been identified where the participation of ROS and RNS is apparent (see Chapters 11-14, 16 and 18). Thus, the field is no more limited to the group of free radical aficionados who have pioneered this area of research but has now gone mainstream. While it is satisfactory for those of us who have been working on this topic for a long time, it has the risk of becoming the “fashionable” motto where those molecules, still mysterious to some, become responsible for everything and anything.

This book reviews the current state of information on reactive oxygen and nitrogen species and their role in cell communication during plant growth, development and adaptation to stress conditions. It addresses current research advances made in the area of reactive oxygen and nitrogen species (ROS and RNS) signaling. These free radical molecules are important in plant-microbe interactions, responses to abiotic stress, stomatal regulation and a range of developmental processes. Due to their short half-life, high diffusion capability and ability to react with different components in the cell, ROS and RNS participate in various processes connected with signaling and communication in plants. The book’s respective chapters address the latest advances made in the niche area of ROS and RNS in plants. It offers a valuable guide for researchers and students alike, providing insights into cutting-edge free radical research. The information on specialized topics presented is also highly relevant for applied fields such as food security, agricultural practices and medicinal use of plants.

A veritable mountain of literature has been published showing the causal relationship of reactive oxygen/nitrogen species in human disease conditions, and there has been an explosion in the understanding of oxidative stress, the protective role of antioxidants and molecular events involved in the regulation of transcription, editing, and translation of key events leading to disease processes. Strategies need to be developed for prevention of diseases by allowing scientists and clinicians to obtain information on new and emerging advances. The molecular mechanisms involved in several diseases including Alzheimer's disease, atherosclerosis, diabetes, arthritis, and Parkinson's disease, as well as disorders of the eye, skin, cardiac, and pulmonary systems are discussed in this volume, along with scientific evidence supporting the value of dietary supplementation with antioxidants in the prevention of cellular damage leading to chronic disease. Special in vivo techniques are also discussed at length, along with the role of molecular studies in human risk assessment.

Research over the years has demonstrated that free radicals mediated oxidative stress lies at the helm of almost all patho-physiological phenomena. These findings emphasize on the need to understand the underlying molecular mechanism(s) and their critical role in the pathogenesis. This book aims to focus on these areas to provide readers a comprehensive outlook about the major redox sensitive pathways and networks involved in various disease conditions. In the first chapter of the book, basic information about the oxidative stress, its generation, its biomarkers and its role in body are discussed. In the next three chapters, the role of oxidative stress in various pathologies ranging from neurological disorders, to cardiovascular diseases, cancers, metabolic diseases and ageing have been described. Chapter 5 cumulatively describes the most important molecular signaling pathways that are affected by reactive oxygen species (ROS). These are the mechanisms which are common denominators in various pathological states. In the next part of the book, various antioxidant strategies to target and mitigate ROS have been discussed with details on the mechanisms. Selenium, being the research focus and interest of the authors for years, the role of selenium as an antioxidant as part of selenoproteins has been included in the book. Finally, the book culminates with authors’ perspective on the future of the redox biology field. Throughout the book, efforts have been made to use simplified language and suitable figures for ease to understand the contents. Although the authors have tried to touch on all the different aspects of oxidative stress in detail, the fact that it is a continuously growing field with updates coming every day, there might be some areas which might not be described in depth. This book is designed for students, young scientists to get acquainted with the redox biology. Overall, this book is a reference to understand the redox regulation of cellular signaling pathways involved in pathogenesis.

Iron is of fundamental importance for the growth, development and well being of almost all living organisms. Multiple biological systems have been developed for the uptake, utilisation, storage and homeostasis of iron in microbes, plants and mammals. e.g. Both iron deficiency and iron overload are found extensively in man: the intimate links between iron and oxidative stress are associated with a wide range of pathologies; iron has a well established role in infections by a wide range of microorganisms and parasites; there is a close link between iron requirements and cellular division with implications for cancers and other metals such as copper and zinc are closely linked with iron metabolism. The first edition of this book was published in 1991. Since then the extensive impact of molecular cell biology on the field of iron biochemistry has opened new horizons in our understanding of the transport and storage of iron and of its homeostasis. The explosive use of molecular biological techniques applied to cellular biology of iron metabolism has resulted in a rapid expansion in the literature which has led to the need for this second edition. This second edition also: Introduces many illustrations and colour photos to make the basic concepts far clearer Includes new chapters on iron and cell division and interactions of iron with other metals - particularly copper and zinc Provides additional anecdotes Incorporates an extensive and up-to-date bibliography
