Applications of Toxicogenomic Technologies to Predictive Toxicology and Risk Assessment


Book Description

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


Book Description

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.




Drug Safety Evaluation


Book Description

Drug Safety Evluation Comprehensive and practical guide presenting a roadmap for safety assessment as an integral part of the development of drugs and therapeutics This fourth edition of Drug Safety Evaluation maintains the central objective of presenting an all-inclusive practical guide for those who are responsible for ensuring the safety of drugs and biologics to patients, healthcare providers, those involved in the manufacture of medicinal products, and all those who need to understand how the safety of these products is evaluated and shepherding valuable candidates to market. Individual chapters address specific approaches to evaluation hazards, including problems that are encountered and their solutions. Also covered are the scientific and philosophical bases for evaluation of specific concerns (e.g., carcinogenicity, development toxicity, etc.) to provide both understanding and guidance for approaching the new problems that have come to face both our society and the new challenges they brought. The many changes in regulatory requirements, pharmaceutical development, technology, and the effects of Covid on our society and science have required both extensive revision to every chapter and the addition of four new chapters. Specific sample topics covered in Drug Safety Evaluation include: The drug development process and the global pharmaceutical marketplace and regulation of human pharmaceutical safety Sources of information for consideration in study and program design and in safety evaluation Electronic records, reporting and submission, screens in safety and hazard assessment, and formulations, routes, and dosage regimens Mechanisms and endpoints of drug toxicity, pilot toxicity testing in drug safety evaluation, and repeat dose toxicity Genotoxicity, QSAR tools for drug safety, toxicogenomics, nonrodent animal studies, and developmental and reproductive toxicity testing An appendix which provides an up to date guide to CROs for conducting studies Drug Safety Evaluation was written specifically for the pharmaceutical and biotechnology industries, including scientists, consultants, and academics, to show a utilitarian yet scientifically valid path to the everyday challenges of safety evaluation and the problem solving that is required in drug discovery and development.

Toxicogenomics in Predictive Carcinogenicity


Book Description

Research over the past decade has demonstrated that TGx methods of various types can be used to discriminate modes of mutagenesis as a function of dose. TGx can quickly inform safety evaluation regarding potential mechanisms of conventional outcomes and can provide essential dose-response information. This can then be used to ascertain the sequence of key events in a putative mode of action as may apply in quantitative cancer risk assessment. With the increasing complexity of research in mode of action investigations it is important to gain a better understand of approaches to data integration and health risk assessment. Furthermore, it is essential to consider how novel test systems and newer methods and approaches may be used in future to gain a better understanding of mechanisms. Toxicogenomics in Predictive Carcinogenicity describes toxicogenomics methods in predictive carcinogenicity testing, mode of action and safety evaluation, and cancer risk assessment. It illustrates these methods using case studies that have yielded significant new information on compounds and classes of compounds that have proven difficult to evaluate using conventional methods alone. This book additionally covers current and potential toxicogenomic research using stem cells as well as new bioinformatics methods for drug discovery and environmental toxicology. This publication is an indispensable tool for postgraduates, academics and industrialists working in biochemistry, genomics, carcinogenesis, pathology, pharmaceuticals, food technology, bioinformatics, risk assessment and environmental toxicology.
