Rnai Technology

RNAi technology is used for large-scale screens that systematically shut down each gene in the cell, which can help identify the components necessary for a particular cellular process or an event such as cell division. Exploitation of the pathway is also a promising tool in biotechnology and medicine. Introducing new technology in the study of RNA

RNA technologies are the driving forces of modern medicine and biotechnology. They combine the fields of biochemistry, chemistry, molecular biology, cell biology, physics, nanotechnology and bioinformatics. The combination of these topics is set to revolutionize the medicine of tomorrow. After more than 15 years of extensive research in the field of RNA technologies, the first therapeutics are ready to reach the first patients. Thus we are witnessing the birth of a very exciting time in the development of molecular medicine, which will be based on the methods of RNA technologies. This volume is the first of a series. It covers various aspects of RNA interference and microRNAs, although antisense RNA applications, hammerhead ribozyme structure and function as well as non-coding RNAs are also discussed. The authors are internationally highly respected experts in the field of RNA technologies.

Maximizing the potential of RNA interference in functional genomics - as well as in the development of therapeutics - continues to be at the forefront of biomedical research. Unlike journal articles, Gene Silencing by RNA Interference: Technology and Application combines essential background to the RNAi field with practical techniques designed by renowned researchers to provide the most diverse and in-depth examination of the subject yet. This book describes methods and protocols for gene silencing and RNA interference. Each chapter provides necessary background to the subject and then gives detailed methods in easy-to-follow steps, along with troubleshooting hints and tips. Following a general and historical introduction, chapters two through eight focus on technical details of the various methods of siRNA design, chemical and enzymatic production, plasmid- and virus-mediated intracellular expression, and other RNAi tools. Chapter nine discusses the exogenous delivery of siRNAs into cells, and the final chapters of the book detail the application of RNAi to dissect gene function in a number of biological systems, including cell-free systems, cultured cells, and whole organisms. From the design and production of RNAi tools to their applications, Gene Silencing by RNA Interference: Technology and Application is the first to present the entire spectrum of activity, design, production, and delivery of RNAi reagents, providing a welcome guide for both academic and commercial use.

Plants are vulnerable to pathogens including fungi, bacteria, and viruses, which cause critical problems and deficits. Crop protection by plant breeding delivers a promising solution with no obvious effect on human health or the local ecosystem. Crop improvement has been the most powerful approach for producing unique crop cultivars since domestication occurred, making possible the main innovations in feeding the globe and community development. Genome editing is one of the genetic devices that can be implemented, and disease resistance is frequently cited as the most encouraging application of CRISPR/Cas9 technology in agriculture. Nanobiotechnology has harnessed the power of genome editing to develop agricultural crops. Nanosized DNA or RNA nanotechnology approaches could contribute to raising the stability and performance of CRISPR guide RNAs. This book brings together the latest research in these areas. CRISPR and RNAi Systems: Nanobiotechnology Approaches to Plant Breeding and Protection presents a complete understanding of the RNAi and CRISPR/Cas9 techniques for controlling mycotoxins, fighting plant nematodes, and detecting plant pathogens. CRISPR/Cas genome editing enables efficient targeted modification in most crops, thus promising to accelerate crop improvement. CRISPR/Cas9 can be used for management of plant insects, and various plant pathogens. The book is an important reference source for both plant scientists and environmental scientists who want to understand how nano biotechnologically based approaches are being used to create more efficient plant protection and plant breeding systems. Shows how nanotechnology is being used as the basis for new solutions for more efficient plant breeding and plant protection Outlines the major techniques and applications of both CRISPR and RNAi technologies Assesses the major challenges of escalating these technologies on a mass scale

RNA interference (RNAi), one of the most exciting discoveries of the last decade, is also known as Post-Transcriptional Gene Silencing (PTGS). It is a conserved host defense response via double-stranded RNA against both endogenous and foreign nucleic acids, and occurs at the levels of transcription, post-transcription and translation. RNA induced gene silencing has been used, with considerable success as a reverse genetics tool for the study of gene function. This technology has revolutionized the gene expression analysis studies because of the specificity and speed it offers. The small RNA molecules central to RNAi are microRNA (miRNA) and small interfering RNA (siRNA). These molecules bind to other RNAs specifically, such as messenger RNA (mRNA), to regulate their activities.In this book, we will discuss how gene silencing methodology has been successfully applied as therapeutic tool against metabolic disorders, cancer, and infectious diseases. This tool has also been successfully used to improve crops resistance against plant pathogens. In contrast to conventional knock-out mutagenesis techniques, the "gene-silencing" vectors, that allow the study of functions of genes whose complete knock-out would otherwise be lethal to the plant.

RNA Interference (RNAi) technology has rapidly become one of the key methods used in functional genomics. RNAi is used to block the expression of genes and create phenotypes that can potentially yield clues about the function of these genes. In the postgenomic era, the elucidation of the physiological function of genes has become the rate-limiting step in the quest to develop 'gene-based drugs' and RNAi could potentially play a pivotal role in the validation of such novel drugs. In this overview, the basic concepts and applications of RNAi biology are discussed. Leading experts from both academia and industry have contributed to this invaluable reference. The volume is forwarded by Andrew Fire, one of the winners of the 2006 Nobel Prize for the discovery of RNA Interference.

This methods manual provides an introduction to RNA interference, the theory behind its many applications, and specific protocols for RNAi, in organisms from plants and C.elegans to Drosophila and mammals. There are also chapters covering small hairpin RNAs and viral-induced gene silencing.

In the past three years, the use of double-stranded RNA to silence gene activity has become widely and rapidly adopted. RNA interference is highly specific and remarkably potent, and it acts on cells and tissues far removed from the site of introduction. The principles behind RNAi are just being uncovered, but this laboratory technique has been applied effectively in a wide variety of animal and plant species. Variations on RNAi are revolutionizing many approaches to experimental biology, complementing traditional genetic technologies with a quicker and less expensive way of mimicking the effects of mutations both in cell cultures and in living animals. Recent advances in the use of RNAi to engineer heritable silencing in mammals, to alter stem cells for organ reconstitution, and to alter the course of disease in model systems indicate that RNAi may have a future in disease therapy. Written by pioneers in this new field and edited by Gregory Hannon, one of its leading figures, RNAi: A Guide to Gene Silencing presents the principles of RNAi and reliable protocols for its laboratory use in Caenorhabditis elegans, Drosophila, plants, avian embryos, mammalian cells, mouse oocytes, and more. This important and unique book is an essential laboratory resource for scientists studying gene regulation and for all experimental biologists interested in the emerging practical applications of RNAi.
