Download or read book Toxicogenomics in non mammalian species written by Stephen Sturzenbaum and published by Frontiers E-books. This book was released on with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some molecules or conditions are exclusively toxic to biological systems and classified as being non-essential; others are essential for life. Nevertheless, above certain threshold even the essential will become toxic. Tightly controlled homeostatic control mechanisms are thus vital drivers of well being, longevity and survival. The identification and characterization of these intricate pathways form the foundations of Toxicogenomics. The initiation, and indeed completion, of numerous non-mammalian genome-sequencing projects, has driven the exponential growth of available genetic sequences. Collating this vast amount of data into functional and mechanistically meaningful units will provide novel insights into pathogenesis, new methods of risk assessment, genetic risk-modifications in preventative medicine and new therapeutic targets for pharmaceutical and biological medicines. This Research Topic issue will explore the current knowledgebase pertaining to the multitude of genomic and toxicological tools within non-mammalian organisms. The encyclopaedic coverage will span the full taxonomic breadth ranging from simple unicellular bacteria and yeast to complex creatures such as birds and fish. The resulting collection of unique, complimentary or indeed contrasting approaches, tools and technologies (which are defined by the availability and feasibility for each organism to study genomics of xenobiotic or stress biology) will not only foster cross-phyla awareness but expand the horizon of Toxicogenomics.

Book excerpt: Functional genomics has come of age. No longer is it an adventure for the avant garde scientist, but it has become an increasingly standardized mainstream tool accessible to any modern biological laboratory. Toxicogenomics studies are now generating an avalanche of data that, with the aid of established informatics methodology, is being translated into biologically meaningful information. This is enabling us to start harvesting the benefits from years of investment in terms of technology, time, and (of course) money. It is therefore timely to bring together leading toxicologists with a wide variety of scientific aims in this book to demonstrate how microarray technology can be successfully applied to different research areas. This book transects biology from bacteria to human, from ecologically relevant sentinel organisms to well-characterized model species, and represents the full toxicogenomics arena from exploratory "blue sky" science to the prospects for incorporation into regulatory frameworks. - Reviews some of the first really fruitful studies made in this area - Covers different organisms ranging from humans to model species and environmental sentinels - Provides a broad view of the area, increasing its attractiveness to researchers working in a variety of specialties

Available in PDF, EPUB and Kindle. Book excerpt: Presenting an up-to-date review of the state-of-the-art and main applications of omics technologies to current hot topics in food sciences, this book is divided into four convenient sections. The first section represents an introduction to the development of foodomics and will provide a general overview of DNA-based and protein-based methods. The second section is focused on the main applications of omics to food safety issues, such as chemical hazards, foodborne pathogens, phages, food authentication or GMO detection. The third section is focused on specific food groups and how omics have revolutionized the investigation of dairy and meat products, seafood, agricultural and fermented food products. Finally, the fourth section is devoted to the link between foodomics and health: hot topics such as nutrimetabolomics, food allergy or probiotics are reviewed here. The book brings together work from top international scientists to produce the most significant academic book for some years on omics and food for a broad audience. It presents unique features not covered so far by other books, such as a detailed description of different strategies and applications of omics techniques to many food sectors and provides a welcome addition to the cutting-edge literature in this area for researchers and professionals in food science and food chemistry.
Download or read book Application of Toxicogenomics to Cross Species Extrapolation written by National Research Council and published by National Academies Press. This book was released on 2006-04-24 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Computational Toxicology written by Edward J. Perkins and published by Elsevier Inc. Chapters. This book was released on 2013-06-04 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: New concepts in toxicology facilitate the use of nonmammalian vertebrate species (e.g., fish) and nonanimal models (nonvertebrates, early embryo vertebrates, or cell-based) as surrogates for mammals. We present a strategy to translate nonmammalian species data to estimate potential impact of chemicals on mammalian species based on highly conserved proteins and biological pathways linked to a defined adverse effect. Protein “targets” and pathway-level information can be mapped across species through identification of orthologs in mammals. Nonmammalian pathway data can be used to identify potential modes of action across species, establish toxicological dose-response relationships, and be used to estimate possible hazard levels of chemicals. Systems-level approaches are identified that offer unique opportunities to incorporate dynamic events such as homeostasis, effects over time, and species-specific parameters relevant to mammals. Ultimately, a pathway-centric focus enables use of alternative models to support protection of mammalian species.
Download or read book Toxicogenomics in Predictive Carcinogenicity written by Russell S Thomas and published by Royal Society of Chemistry. This book was released on 2016-06-16 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Insect Nicotinic Acetylcholine Receptors written by Steeve Hervé Thany and published by Springer Science & Business Media. This book was released on 2011-01-11 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to summarize our understanding on the insect nicotinic acetylcholine receptors. This area of research received great impetus from the identification of the first subunit sequences to be used as neonicotinoid insecticide target sites. Although a book of this nature can provide the details only of commonly published results, it is hoped that it may provide a useful guide to the newcomer to the field as well as to point out some of the future challenges. For example, we need to determine the precise subunit nomenclature of insect nicotinic receptors. This nomenclature varies amongst species and this led to some of the early confusion that persists. We need to be precise in identifying the subunit composition of native insect nicotinic receptor subtypes, their functional properties and physiological roles.
