Book Description
The development of recombinant DNA technology and methods for transferring recombinant genes into plants has brought about significant advances in plant science. First, it has allowed investigation, using reporter genes, into the transcriptional regulation of plant genes—a key to the under standing of the biochemical basis of growth and development in plants. Second, gene transfer technology has facilitated the molecular cloning, by tagging genomic sequences, of important genes (e. g. , homeotic genes) whose gene products control the normal pattern of growth and differentia tion of plants. Third, overproducing foreign or endogenous proteins in plants can often lead to a better understanding of biochemical and physiological processes. Fourth, gene transfer technology has allowed the improvement of plant agricultural productivity. For example, plants have been engineered with improved viral resistance or the ability to withstand herbicide attack, therefore allowing a more effective use of herbicides to kill weeds. Fifth, there have been recent successes that demonstrate the potential use of plants as biotechnological chemical factories. For example, it is possible to use plants in the production of human antibodies and antigens of medical importance. It has been demonstrated recently that plants can be engineered to produce modified oils and even plastics! This paves the way to redirect agriculture from the production of surplus foods to the production of bio technological products of industrial importance.

Book Description
Gene transfer research is a rapidly advancing field that involves the introduction of a genetic sequence into a human subject for research or diagnostic purposes. Clinical gene transfer trials are subject to regulation by the U.S. Food and Drug Administration (FDA) at the federal level and to oversight by institutional review boards (IRBs) and institutional biosafety committees (IBCs) at the local level before human subjects can be enrolled. In addition, at present all researchers and institutions funded by the National Institutes of Health (NIH) are required by NIH guidelines to submit human gene transfer protocols for advisory review by the NIH Recombinant DNA Advisory Committee (RAC). Some protocols are then selected for individual review and public discussion. Oversight and Review of Clinical Gene Transfer Protocols provides an assessment of the state of existing gene transfer science and the current regulatory and policy context under which research is investigated. This report assesses whether the current oversight of individual gene transfer protocols by the RAC continues to be necessary and offers recommendations concerning the criteria the NIH should employ to determine whether individual protocols should receive public review. The focus of this report is on the standards the RAC and NIH should use in exercising its oversight function. Oversight and Review of Clinical Gene Transfer Protocols will assist not only the RAC, but also research institutions and the general public with respect to utilizing and improving existing oversight processes.

Book Description
Biology is the study of living things. The classical approach might be described as holistic and descriptive, whereas the modern molecular - proach aims to be investigative, reductionist, and mechanistic . Genes contain all the information for the structure of all living things ; thus, the understanding of how genes are regulated is an important step toward understanding the nature of living things. The study of gene regulation has been made more tractable by the design of simple expe- mental models in which a single gene can be isolated from the milieu of the organism. The new science of molecular biology has introduced techniques that permit the design of such experimental models. In - sence, the genome of the organism is dissected in such a manner that specific genes may now be introduced into an appropriate cell line . Subsequent analysis of the proteins expressed from the genes under study results in the identification of the regulatory DNA sequences .

Book Description
Understanding gene function and regulation requires rigorous testing in live cells and organisms. Recent advances have provided a variety of new strategies for delivering DNA and RNA into cells and probing their expression, as well as new clinical applications that rely upon the introduction of genetic material. The vast number of available techniques for clinical and laboratory research often makes selecting the optimal method a difficult process. Gene Transfer: Delivery and Expression of DNA and RNA provides the first comprehensive guide to technical approaches for delivering nucleic acids into cells and organisms and of ensuring (even manipulating) appropriate expression. The detailed, step-by-step protocols cover a variety of methods, both well established and newly evolving. These include viral and nonviral methods of gene delivery, transgenic approaches, strategies for the regulation of transgene expression, and modification of the host response. The introductory matter to each chapter includes concise technical and theoretical discussions with considerations for selection of the appropriate system and strategies for delivery.

Book Description
The production of proteins in mammalian cells is an important tool in numerous scientific and commercial areas. For example, proteins for human therapy, vaccination or diagnostic applications are typically produced in mammalian cells. Gene cloning, protein engineering, biochemical and biophysical characterization of proteins also require the use of gene expression in mammalian cells. Other applications in widespread use involve screening of libraries of chemical compounds in drug discovery, and the development of cell-based biosensors.This book presents a state-of-the-art comprehensive coverage of the technical aspects of gene expression in mammalian cells, written by experienced scientists working at the forefront of the field.

Book Description
Transfer and Expression of Eukaryotic Genes documents the progress in our understanding of the transfer and expression of eukaryotic genes. This book covers topics organized around three themes: gene expression and its regulation; in vivo gene transfer and development; and viral gene and oncogene systems. This text is divided into three sections encompassing 25 chapters and begins with an overview of the molecular basis of gene expression, with emphasis on transcription complexes that account for transcription control in eukaryotic genes. It then turns to experiments that assess the in vitro stimulatory effect of the SV40 72-bp repeat on specific transcription from heterologous promoter elements using a HeLa whole cell extract. The reader is methodically introduced to the regulation signals and factors of histone gene transcription; transcriptional control of beta-globin and liver-specific genes in mouse cells; and gene transfer in Drosophila and the sea urchin Strongylocentrotus purpuratus. This book also considers the splicing of messenger RNA precursors and the regulation of thymidine kinase enzyme expression, and then concludes with a chapter that describes the activation of the myc oncogene by chromosomal translocation. This book will be of interest to students and researchers in fields ranging from molecular genetics to microbiology, biochemistry, pathology, and immunology.

Book Description
How small can a free-living organism be? On the surface, this question is straightforward-in principle, the smallest cells can be identified and measured. But understanding what factors determine this lower limit, and addressing the host of other questions that follow on from this knowledge, require a fundamental understanding of the chemistry and ecology of cellular life. The recent report of evidence for life in a martian meteorite and the prospect of searching for biological signatures in intelligently chosen samples from Mars and elsewhere bring a new immediacy to such questions. How do we recognize the morphological or chemical remnants of life in rocks deposited 4 billion years ago on another planet? Are the empirical limits on cell size identified by observation on Earth applicable to life wherever it may occur, or is minimum size a function of the particular chemistry of an individual planetary surface? These questions formed the focus of a workshop on the size limits of very small organisms, organized by the Steering .Group for the Workshop on Size Limits of Very Small Microorganisms and held on October 22 and 23, 1998. Eighteen invited panelists, representing fields ranging from cell biology and molecular genetics to paleontology and mineralogy, joined with an almost equal number of other participants in a wide-ranging exploration of minimum cell size and the challenge of interpreting micro- and nano-scale features of sedimentary rocks found on Earth or elsewhere in the solar system. This document contains the proceedings of that workshop. It includes position papers presented by the individual panelists, arranged by panel, along with a summary, for each of the four sessions, of extensive roundtable discussions that involved the panelists as well as other workshop participants.
