Transgenesis Techniques


Book Description

The past decade has witnessed a spectacular explosion in both the devel- ment and use of transgenic technologies. Not only have these been used to aid our fundamental understanding of biologic mechanisms, but they have also faci- tated the development of a range of disease models that are now truly beginning to impact upon our approach to human disease. Some of the most exciting model systems relate to neurodegenerative disease and cancer, where the availability of appropriate models is at last allowing radically new therapies to be developed and tested. This latter point is of particular significance given the current concerns of the wider public over both the use of animal models and the merits of using genetically modified organisms. Arguably, advances of the greatest significance have been made using mammalian systems—driven by the advent of embryonic stem-cell–based strategies and, more recently, by cloning through nuclear transfer. For this reason, this new edition of Transgenesis Techniques focuses much more heavily on manipulation of the mammalian genome, both in the general discussions and in the provision of specific protocols.




Transgenesis Techniques


Book Description

This revised and updated edition of a much-acclaimed classic presents a collection of readily reproducible techniques for the generation and analysis of transgenic animals, with emphasis on the manipulation of the mammalian genome. It concentrates on the creation and maintenance of genetically modified murine strains, providing access to the germline by both conventional pronuclear injection, and by retroviral and adenoviral infection. Extensive coverage is also given to the generation, maintenance, and manipulation of embryonic stem cell lineages, with protocols for both constitutive and conditional (Cre-lox or the Flp-frt systems) gene targeting. Additional chapters provide cutting-edge techniques for the cryopreservation of both male and female germlines, for the generation of transgenic sheep by nuclear transfer, and for the basic analysis of transgenic organisms.




Safety of Genetically Engineered Foods


Book Description

Assists policymakers in evaluating the appropriate scientific methods for detecting unintended changes in food and assessing the potential for adverse health effects from genetically modified products. In this book, the committee recommended that greater scrutiny should be given to foods containing new compounds or unusual amounts of naturally occurring substances, regardless of the method used to create them. The book offers a framework to guide federal agencies in selecting the route of safety assessment. It identifies and recommends several pre- and post-market approaches to guide the assessment of unintended compositional changes that could result from genetically modified foods and research avenues to fill the knowledge gaps.




Advanced Protocols for Animal Transgenesis


Book Description

This laboratory manual, published in cooperation with the International Society for Transgenic Technology (ISTT), provides almost all current methods that can be applied to the creation and analysis of genetically modified animals. The chapters have been contributed by leading scientists who are actively using the technology in their laboratories. Based on their first-hand experience the authors also provide helpful notes and troubleshooting sections. Topics range from standard techniques, such as pronuclear microinjection of DNA, to more sophisticated and modern methods, such as the derivation and establishment of embryonic stem (ES) cell lines, with defined inhibitors in cell culture medium. In addition, related topics with relevance to the field are addressed, including global web-based resources, legal issues, colony management, shipment of mice and embryos, and the three R’s: refinement, reduction and replacement.




Transgenic Mouse Methods and Protocols


Book Description

Marten Hofker and Jan van Deursen have assembled a multidisciplinary collection of readily reproducible methods for working with mice, and particularlyfor generating mouse models that will enable us to better understand gene function. Described in step-by-step detail by highly experienced investigators, these proven techniques include new methods for conditional, induced knockout, and transgenic mice, as well as for working with mice in such important research areas as immunology, cancer, and atherosclerosis. Such alternative strategies as random mutagenesis and viral gene transduction for studying gene function in the mouse are also presented.




Animal Transgenesis and Cloning


Book Description

Designed to be a concise, balanced introduction to this dynamic subject, covering key issues and current techniques currently used in animal transgenesis and cloning. Provides the essentials of the subject, from the molecular basis of gene structure and function to therapeutic gene cloning in humans. Social and ethical implications of this important area of research are also considered.




Transgenic Animals


Book Description

During the past 20 years, transgenesis has become a popular technique and a crucial tool for molecular geneticists and biologists. Transgene expression is now better-controlled and even specifically inducible by exogenous factors. While these techniques have quite significantly transformed the experimental approaches taken by biologists, the applications are more limited than expected and concerns have arisen regarding biosafety as well as physiological, social, and philosophical issues. Transgenic Animals: Generation and Use contains articles on the techniques used to generate transgenic animals and a section on the preparation of vectors for the optimally controlled expression of transgenes. It also examines the use of transgenic animals in the study of gene function and human diseases, the preparation of recombinant proteins and organs for pharmaceutical and medical use, and the improvement of genetic characteristics of farm animals. Finally, it discusses more recent problems generated by transgenic animals including conservation of transgenic lines, specific database patenting, biosafety, and bioethics. Drawn from both academia and industry, the contributors to this monograph present in one concise volume all the relevant information on the different aspects of transgenesis. This book can be used as both a reference book and a textbook for specialized university courses and will be of interest to everyone involved in basic research in animal biology, molecular genetics, animal biotechnology, pharmaceutical science, and medicine.




Transgenesis Techniques


Book Description

One of the major challenges currently facing the scientific community is to understand the function of the multitude of protein-coding genes that were revealed when the human genome was fully sequenced. In Transgenesis Techniques: Principles and Protocols, Third Edition, experts in the field fully update and expand upon the previous edition in order to detail the transgenic techniques currently used to modify the genome. The volume explores classic procedures to genetically modify mice and other model organisms, as well as cutting-edge practices involving microinjection, site-specific recombination systems, cryopreservation, and many other topics. Written in the highly successful Methods in Molecular BiologyTM series format, the chapters include brief introductions to their subjects, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and notes sections, highlighting tips on troubleshooting and avoiding known pitfalls. Comprehensive and state-of-the-art, Transgenesis Techniques: Principles and Protocols, Third Edition is a comprehensive practical guide to the generation of transgenic animals and an invaluable source of information in any lab currently involved in transgenic techniques.

Transgenic Insects


Book Description

Insect transgenesis promises improvements in agriculture, pharmaceuticals and public health. Many important insects can now be routinely transformed with effectors that have useful applications. Agriculture presents the largest market for transgenic insects and has a foundational history of success with sterile insect technique for control of pests including Mediterranean fruit flies and screwworms. Biotechnology will contribute superior markers, suppressible sterility and sex-conversion. Public health is also seeing transgenic mosquitoes developed which suppress natural populations and are incapable of transmitting disease. Experts in the field will contribute their insights into the latest technology and its applications. Authors will also consider the larger risks, social and economic aspects of transgenic insects whose value must be proven in political, regulatory and public acceptance arenas.
