Toxicogenomic Technologies and Risk Assessment of Environmental Carcinogens: A Workshop Summary

by National Research Council

Toxicogenomics is a discipline that combines expertise in toxicology, genetics, molecular biology, and environmental health to help understand the response of living organisms to stressful environments. The National Research Council convened a workshop to discuss how toxicogenomic data could be applied to improve risk assessments, particularly cancer risk from environmental exposure to chemicals. Risk assessments serve as the basis of many public-health decisions in environmental, occupational, and consumer protection from chemicals. The workshop provided a forum for communities of experts, including those working in "-omics" and those in the policy arena, to discuss where their fields intersect, and how toxicogenomics could address critical knowledge gaps in risk assessments.

Toxicologic Pathology: A Primer

by Gregory Argentieri

There has been an enormous growth of interest in the field of toxicologic pathology and particularly on its impact on nonclinical safety assessment in global drug development and in the environment. Toxicologic pathologists play an important role in detecting test article-related adverse effects by characterizing morphologic changes in animal tissues and/or body fluids under prescribed study conditions or less clearly defined conditions in the environment and in the interpretation of these findings relative to human risk. In fact, pathology evaluation is often the single most important decision-making factor in nonclinical safety assessments as 80% of drug candidate attrition has been attributed to pathology findings in toxicity studies. There are currently no primers or basic overviews covering the field of toxicologic pathology, whereas there are at least several basic books that cover the sister field of toxicology.Toxicologic Pathology: A Primer is a practical, easy-to-use reference designed to contain core information provided by board-certified veterinary pathologists, all experts in the field. The Primer contains the basic, underlying principles of toxicologic pathology at the introductory level; thus it will be valuable to the veterinary pathology student who may be considering a career in the field as well as a companion to the seasoned toxicologic pathologist who wants a succinct refresher. The Primer is arranged as chapters presenting each major organ system preceded by an overview chapter covering the field of toxicologic pathology followed by a “concept” chapter describing the role of toxicologic pathology in drug development. Photomicrographs and illustrations provide visual context.The organ system chapters provide histopathologic descriptions of lesions observed in toxicity studies of test articles in drug development and testing of chemicals that may negatively impact the environment. Each organ system chapter provides additional information related to a particular lesion to aid the reader in better understanding its toxicologic significance relative to human risk.Each organ system chapter contains: A brief introduction A succinct description of the anatomy and physiology of the system Descriptions of the most important pathological lesions Differential diagnoses Biological consequences, pathogenesis, and/or mechanism of lesion formation Associated clinical pathology correlates Nonclinical safety scientists such as study directors, non-pathology-oriented contributing scientists such as senior toxicology report reviewers, scientific management of Contract Research Organizations (CROs), and students should find the Primer useful in helping them understand the fundamentals of toxicologic pathology.

Toxicological and Performance Aspects of Oxygenated Motor Vehicle Fuels

Toxicology and Environmental Health Information Resources: The Role of the National Library of Medicine

by Catharyn T. Liverman Carrie E. Ingalls Carolyn E. Fulco Howard M. Kipen

The environment is increasingly recognized as having a powerful effect on human and ecological health, as well as on specific types of human morbidity, mortality, and disability. While the public relies heavily on federal and state regulatory agencies for protection from exposures to hazardous substances, it often looks to health professionals for information about routes of exposure and the nature and extent of associated adverse health consequences. However, most health professionals acquire only a minimal knowledge of toxicology during their education and training.In 1967 the National Library of Medicine (NLM) created an information resource, known today as the Toxicology and Environmental Health Information Program (TEHIP). In 1995 the NLM asked the Institute of Medicine to examine the accessiblity and utility of the TEHIP databases for the work of health professionals.This resulting volume contains chapters on TEHIP and other toxicology and environmental health databases, on understanding the toxicology and environmental health information needs of health professionals, on increasing awareness of information resources through training and outreach, on accessing and navigating the TEHIP databases, and on program issues and future directions.

Toxicology and Epigenetics

by Saura C. Sahu

Epigenetics is the study of both heritable and non-heritable changes in the regulation of gene activity and expression that occur without an alteration in the DNA sequence. This dynamic and rapidly developing discipline is making its impact across the biomedical sciences, in particular in toxicology where epigenetic differences can mean that different individuals respond differently to the same drug or chemical.Toxicology and Epigenetics reflects the multidimensional character of this emerging area of toxicology, describing cutting-edge molecular technologies to unravel epigenetic changes, the use of in vivo and in vitro models, as well as the potential use of toxicological epigenetics in regulatory environments. An international team of experts consider the interplay between epigenetics and toxicology in a number of areas, including environmental, nutritional, pharmacological, and computational toxicology, nanomaterials, proteomics and metabolomics, and cancer research.Topics covered include:environment, epigenetics and diseasesDNA methylation and toxicogenomics chromatin at the intersection of disease and therapyepigenomic actions of environmental arsenicalsenvironment, epigenetics and cardiovascular healthtoxicology, epigenetics and autoimmunityocular epigenomics: potential sites of environmental impact in development and diseasenuclear RNA silencing and related phenomena in animalsepigenomics - impact for drug safety sciencesmethods of global epigenomic profilingtranscriptomics: applications in epigenetic toxicologyToxicology and Epigenetics is an essential insight into the current trends and future directions of research in this rapidly expanding field for investigators, toxicologists, risk assessors and regulators in academia, industry and government.

Toxicology of Amphibian Tadpoles

by Eduardo Alves de Almeida Juliane Silberschmidt Freitas

Anuran amphibians are among the animal groups with the highest rate of population decline on the planet. Among the factors driving this decline are environmental pollutants, whose negative effects on larvae and tadpoles are still relatively little studied. This is the first book devoted entirely to studying the effects of environmental pollutants on amphibian tadpoles. Throughout its 14 chapters, various aspects of the toxic effects of different classes of environmental contaminants are explored, such as the toxicokinetics of toxic compounds in tadpoles and their health effects, which may result in negative consequences at populations level.

Toxicology of Biological Communication: Lessons from Endocrine Disruptors and the Exposome

by Robert Barouki Xavier Coumoul Etienne Blanc

Communication is vital for biological systems. This book covers how environmental stressors can disrupt these communications leading to adverse outcomes and goes beyond endocrine disruption. Since the endocrine system is primarily a communication system, endocrine disruption is the clearest example of communication toxicology. However, other physiological systems rely heavily on communication and therefore its disruption by toxicants can have considerable impacts. This is illustrated with the effects of toxicants on the nervous and the immune system. The exposome concept has considerably changed the field of toxicology as it tends to integrate different exposures and highlights their interactions. This book discusses how it has also fueled the relevance of communication between different systems to better understand the mechanisms of toxicity. The dialogue between chemicals and the dietary imbalance as well as between chemicals and psycho-social stress is further discussed and integrated into the global communication disruption concept. This book is intended for researchers, scientists, students, NGO experts, and all interested citizens with some biological background.
