Applications of Toxicogenomic Technologies to Predictive Toxicology and Risk Assessment by National Research Council,Division on Earth and Life Studies,Board on Life Sciences,Board on Environmental Studies and Toxicology,Committee on Applications of Toxicogenomic Technologies to Predictive Toxicology Pdf
The new field of toxicogenomics presents a potentially powerful set of tools to better understand the health effects of exposures to toxicants in the environment. At the request of the National Institute of Environmental Health Sciences, the National Research Council assembled a committee to identify the benefits of toxicogenomics, the challenges to achieving them, and potential approaches to overcoming such challenges. The report concludes that realizing the potential of toxicogenomics to improve public health decisions will require a concerted effort to generate data, make use of existing data, and study data in new waysâ€"an effort requiring funding, interagency coordination, and data management strategies.

Application of Toxicogenomics to Cross-Species Extrapolation by National Research Council,Division on Earth and Life Studies,Board on Life Sciences,Board on Environmental Studies and Toxicology,Committee on Emerging Issues and Data on Environmental Contaminants,Committee on Applications of Toxicogenomics to Cross-Species Extrapolation Pdf
Some of what we know about the health effects of exposure to chemicals from food, drugs, and the environment come from studies of occupational, inadvertent, or accident-related exposures. When there is not enough human data, scientists rely on animal data to assess risk from chemical exposure and make health and safety decisions. However, humans and animals can respond differently to chemicals, including the types of adverse effects experienced and the dosages at which they occur. Scientists in the field of toxicogenomics are using new technologies to study the effects of chemicals. For example, in response to a particular chemical exposure, they can study gene expression ("transcriptomics"), proteins ("proteomics") and metabolites ("metabolomics"), and they can also look at how individual and species differences in the underlying DNA sequence itself can result in different responses to the environment. Based on a workshop held in August 2004, this report explores how toxicogenomics could enhance scientists' ability to make connections between data from experimental animal studies and human health.
Toxicogenomics is the integration of genomics to toxicology. This technology is a powerful tool for collecting information from a large number of biological samples simultaneously and thus it is very useful for large-scale screening of potential toxicants. Toxicogenomics: A Powerful Tool For Toxicity Assessment provides up-to-date state-of-the-art information presented by the recognized experts, and is therefore an authoritative source of current knowledge in this field of research. The potential link between toxicology, genetics and human diseases makes this book very useful to investigators in many and varied disciplines of science and toxicology. Topics covered include: mechanistic toxicogenomics analysis and interpretation of toxicogenomic data principles of data mining in toxicogenomics design issues in toxicogenomics studies sources of variability in toxicogenomic assays Escherichia coli stress response as a tool for detection of toxicity toxicogenomics as a tool to assess immunotoxicity toxicogenomics and ecogenomics for studying endocrine disruption and basic biology use of toxicogenomics as an early predictive tool for hepatotoxicity nutrigenomics: the application of genomic signatures in nutrition-related research application of toxicogenomics in drug discovery potential uses of toxicogenomic biomarkers in occupational health and risk assessment usefulness of toxicogenomics in the regulatory environment perspectives on toxicogenomics at the US Environmental Protection Agency Toxicogenomics: A Powerful Tool For Toxicity Assessment is an essential resource for research scientists currently engaged in toxicogenomics, and will also be of interest to researchers working in toxicology, genetics, medicine, pharmacology, and food sciences, and to regulators and risk assessors of drug, food, environmental and agricultural products.

Big Data in Predictive Toxicology by Daniel Neagu,Andrea-Nicole Richarz Pdf
The rate at which toxicological data is generated is continually becoming more rapid and the volume of data generated is growing dramatically. This is due in part to advances in software solutions and cheminformatics approaches which increase the availability of open data from chemical, biological and toxicological and high throughput screening resources. However, the amplified pace and capacity of data generation achieved by these novel techniques presents challenges for organising and analysing data output. Big Data in Predictive Toxicology discusses these challenges as well as the opportunities of new techniques encountered in data science. It addresses the nature of toxicological big data, their storage, analysis and interpretation. It also details how these data can be applied in toxicity prediction, modelling and risk assessment. This title is of particular relevance to researchers and postgraduates working and studying in the fields of computational methods, applied and physical chemistry, cheminformatics, biological sciences, predictive toxicology and safety and hazard assessment.

Science and Decisions by National Research Council,Division on Earth and Life Studies,Board on Environmental Studies and Toxicology,Committee on Improving Risk Analysis Approaches Used by the U.S. EPA Pdf
Risk assessment has become a dominant public policy tool for making choices, based on limited resources, to protect public health and the environment. It has been instrumental to the mission of the U.S. Environmental Protection Agency (EPA) as well as other federal agencies in evaluating public health concerns, informing regulatory and technological decisions, prioritizing research needs and funding, and in developing approaches for cost-benefit analysis. However, risk assessment is at a crossroads. Despite advances in the field, risk assessment faces a number of significant challenges including lengthy delays in making complex decisions; lack of data leading to significant uncertainty in risk assessments; and many chemicals in the marketplace that have not been evaluated and emerging agents requiring assessment. Science and Decisions makes practical scientific and technical recommendations to address these challenges. This book is a complement to the widely used 1983 National Academies book, Risk Assessment in the Federal Government (also known as the Red Book). The earlier book established a framework for the concepts and conduct of risk assessment that has been adopted by numerous expert committees, regulatory agencies, and public health institutions. The new book embeds these concepts within a broader framework for risk-based decision-making. Together, these are essential references for those working in the regulatory and public health fields.

Toxicity-Pathway-Based Risk Assessment by National Research Council,Division on Earth and Life Studies,Board on Environmental Studies and Toxicology,Standing Committee on Risk Analysis Issues and Reviews Pdf
In 2007, the National Research Council envisioned a new paradigm in which biologically important perturbations in key toxicity pathways would be evaluated with new methods in molecular biology, bioinformatics, computational toxicology, and a comprehensive array of in vitro tests based primarily on human biology. Although some considered the vision too optimistic with respect to the promise of the new science, no one can deny that a revolution in toxicity testing is under way. New approaches are being developed, and data are being generated. As a result, the U.S. Environmental Protection Agency (EPA) expects a large influx of data that will need to be evaluated. EPA also is faced with tens of thousands of chemicals on which toxicity information is incomplete and emerging chemicals and substances that will need risk assessment and possible regulation. Therefore, the agency asked the National Research Council to convene a symposium to stimulate discussion on the application of the new approaches and data in risk assessment. The symposium was held on May 11-13, 2009, in Washington, DC, and included presentations and discussion sessions on pathway-based approaches for hazard identification, applications of new approaches to mode-of-action analyses, the challenges to and opportunities for risk assessment in the changing paradigm, and future directions.

Regulatory Toxicology by Franz-Xaver Reichl,Michael Schwenk Pdf
This book will be written by experts for professionals, scientists and all those involved in toxicological data generation and decision-making. It is the updated and expanded version of a monograph published in German in 2004. Chemical safety is regulated on various levels including production, storage, transport, handling, disposal or labelling. This book deals comprehensively with the safety-ensuring methods and concepts employed by regulatory agencies, industry and academics. Toxicologists use experimental and scientific approaches for data collection, e.g. about chemical hazards, physicochemical features or toxicokinetics. The respective experimental methods are described in the book. Toxicologists also deal with much insecurity in the exposure and effect scenarios during risk assessment. To overcome these, they have different extrapolation methods and estimation procedures at their disposal. The book describes these methods in an accessible manner. Differing concepts from one regulation area to another are also covered. Reasons and consequences become evident when reading the book. Altogether, the book Regulatory Toxicology will serve as an excellent reference.
