Toxins And Signal Transduction

Of the multitude of toxins known and the enormous variety of effects they cause, of particular interest are those that influence signal transduction. Intercellular communication by chemical signals is essential for the functioning of multicellular organisms. Many toxins exert their biological effects by interfering with the signal transduction initiated by these chemicals (hormones, transmitters, growth factors, and other mediators). Up-to-date information is provided by outstanding experts, who discuss the molecular mechanisms involved in the action of many toxins, as well as the use of toxins as informative tools with which to study signal transduction and their potential therapeutic usage. This volume contains useful information for the experimentalist interested in toxins or in signal transduction, as well as for the reader interested in gaining a comprehensive overview of the field. The Cellular and Molecular Mechanisms of Toxin Action series will include monographs on signal transduction, secretory systems, cytoskeleton, selective neurotoxicity of natural, recombinant and chimeric toxins giving a broader emphasis on the mechanism of action, structure-function relationship, and use of toxins as research tools and their therapeutic applications.

Many of the toxic effects elicited by xenobiotics can be explained at the molecular level by their interaction with receptors or by disruption or interference with receptor-mediated signal transduction pathways. This volume describes molecular approaches and reviews of current research. It provides reviews of numerous research areas which are direc

Many bacteria, animals, and plants produce toxins that can prove lethal to other organisms. Toxins are a form of "biological warfare" that helps their producer to survive and so confer an evolutionary advantage. They display an extraordinary range of complexity, from the formic acid provided by ants to bacterial proteins composed of thousands of amino acids. This Guidebook considers the more complex protein and peptide toxins and groups them according to their mode of action. Topics covered include: membrane-permeabilizing toxins; toxins affecting signal transduction and protein synthesis; cytoskeleton-affecting toxins; toxins affecting the immune and inflammatory response. This class of biomolecules will be of interest to a wide range of researchers in cell biology, neuroscience, and toxicology.

Bacterial toxins that act inside cells interact very specifically with key components of the cell and some even manipulate the cell in subtle ways for their own purposes. These potent toxins, described in this 2005 book, will be of interest to both microbiologists and cell biologists. Some of these toxins are conventional multidomain toxins that are self-programmed to enter cells. Others are delivered by type III mechanisms, often as a package of potent molecules. The molecular targets for all these toxins mediate signal transduction and the cell cycle to regulate the crucial processes of cell growth, cell division and differentiation. Thus these potent toxins are not only responsible for disease, but also provide a powerful set of tools with which to interrogate the biology of the cell. In addition such toxins may act directly to promote carcinogenesis and hence their study is also of interest in a wider context.

Covering a key topic due to growing research into the role of signaling mechanisms in toxicology, this book focuses on practical approaches for informatics, big data, and complex data sets. Combines fundamentals / basics with experimental applications that can help those involved in preclinical drug studies and translational research Includes detailed presentations of study methodology and data collection, analysis, and interpretation Discusses tools like experimental design, sample handling, analytical measurement techniques

Signal transduction is any process by which a cell converts one kind of signal or stimulus into another. Processes referred to as signal transduction often involve a sequence of biochemical reactions inside the cell, which are carried out by enzymes and linked through second messengers. In many transduction processes, an increasing number of enzymes and other molecules become engaged in the events that proceed from the initial stimulus. Responses of cells to environmental signals, toxins and stressors have profound implications for diverse aspects of human health and disease including development, cystic fibrosis, diabetes, asthma, heart, auto-immune diseases and cancer. The delineation of the signal transduction pathways affected in these and other complex human diseases are likely to present new avenues for therapeutic intervention and understanding of human disease mechanisms. This book presents the latest research in the field.
