Antiviral RNAi


Book Description

Viruses and RNAi share an intricate relationship at many levels. RNAi is an important antiviral defense mechanism in plants and invertebrates, microRNAs – of viral or cellular origin – affect many aspects of virus biology, and replication of many, if not all, mammalian viruses can be suppressed by RNAi. Antiviral RNAi: Concepts, Methods, and Applications provides a collection of protocols for the analysis of viral small RNAs and natural antiviral RNAi responses as well as for the development and optimization of RNAi-based antiviral drugs. As RNAi is a central regulatory mechanism in the cell, the methods in this volume can also be applied out of the context of a virus infection. Divided into five convenient parts, this detailed volume reviews important basic concepts in the field of antiviral RNAi, provides experimental and bio-informatic tools for the analysis of small silencing RNAs, covers methods to biochemically dissect RNAi-based antiviral defense and viral counter-defense mechanisms, describes methods for the design, expression, and delivery of therapeutic antiviral siRNAs, and finally presents genome-wide RNAi approaches for the identification of factors involved in virus replication. Written in the highly successful Methods in Molecular BiologyTM series format, chapters contain introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and accessible, Antiviral RNAi: Concepts, Methods, and Applications serves as an ideal guide for both novice and experienced researchers alike striving to dissect the role of RNAi in the viral life cycle or to further boost the development of novel therapeutics and experimental tools based on RNAi technology.




Regulatory RNAs


Book Description

Recent progress in high-throughput technologies and genome wide transcriptome studies have lead to a significant scientific milestone of discovering non-coding RNAs (ncRNAs) which spans through a major portion of the genome. These RNAs most often act as riboregulators, and actively participate in the regulation of important cellular functions at the transcriptional and/or post-transcriptional levels rather than simply being an intermediated messenger between DNA and proteins. As the appreciation for the importance of ncRNAs continues to emerge, it is also increasingly clear that these play critical roles in gene regulatory processes during development and differentiation. Further, regulatory RNAs are useful biomarkers for diagnosis of diseases. Hence these RNA regulators are essential to the development of therapeutics. This book on “Regulatory RNAs” offers a comprehensive view on our current understanding of these regulatory RNAs viz. siRNA, miRNA, piRNA, snoRNA, long non-coding RNA, small RNA etc. It addresses both the biogenesis and mechanism of action of regulatory RNAs with a primary focus on their annotation, experimental methodologies (microarray, next-gen sequencing etc.) for their discovery, computational tools for their prediction, and above all, applications of these revolutionary regulatory molecules in understanding biological systems and diseases, including therapeutics. This comprehensive volume is intended for readers with research or teaching interests in ncRNA biology and will provide a major information resource on current research in the fast-moving fields of RNA and gene expression regulation. Cutting-edge and concise, “Regulatory RNAs: Basics, Methods and Applications” promises to support vital research in the field of regulatory RNAs, ever-continuing to grow rapidly and gain increasing importance in basic and translational biology.




Genetics and Molecular Biology


Book Description

In the first edition of Genetics and Molecular Biology, renowned researcher and award-winning teacher Robert Schleif produced a unique and stimulating text that was a notable departure from the standard compendia of facts and observations. Schleif's strategy was to present the underlying fundamental concepts of molecular biology with clear explanations and critical analysis of well-chosen experiments. The result was a concise and practical approach that offered students a real understanding of the subject. This second edition retains that valuable approach--with material thoroughly updated to include an integrated treatment of prokaryotic and eukaryotic molecular biology. Genetics and Molecular Biology is copiously illustrated with two-color line art. Each chapter includes an extensive list of important references to the primary literature, as well as many innovative and thought-provoking problems on material covered in the text or on related topics. These help focus the student's attention of a variety of critical issues. Solutions are provided for half of the problems. Praise for the first edition: "Schleif's Genetics and Molecular Biology... is a remarkable achievement. It is an advanced text, derived from material taught largely to postgraduates, and will probably be thought best suited to budding professionals in molecular genetics. In some ways this would be a pity, because there is also gold here for the rest of us... The lessons here in dealing with the information explosion in biology are that an ounce of rationale is worth a pound of facts and that, for educational value, there is nothing to beat an author writing about stuff he knows from theinside."--Nature. "Schleif presents a quantitative, chemically rigorous approach to analyzing problems in molecular biology. The text is unique and clearly superior to any currently available."--R.L. Bernstein, San Francisco State University. "The greatest strength is the author's ability to challenge the student to become involved and get below the surface."--Clifford Brunk, UCLA

Exploitation of the pathway is also a promising tool in biotechnology and medicine. Introducing new technology in the study of RNA




RNA Exosome


Book Description

The diversity of RNAs inside living cells is amazing. We have known of the more “classic” RNA species: mRNA, tRNA, rRNA, snRNA and snoRNA for some time now, but in a steady stream new types of molecules are being described as it is becoming clear that most of the genomic information of cells ends up in RNA. To deal with the enormous load of resulting RNA processing and degradation reactions, cells need adequate and efficient molecular machines. The RNA exosome is arising as a major facilitator to this effect. Structural and functional data gathered over the last decade have illustrated the biochemical importance of this multimeric complex and its many co-factors, revealing its enormous regulatory power. By gathering some of the most prominent researchers in the exosome field, it is the aim of this volume to introduce this fascinating protein complex as well as to give a timely and rich account of its many functions. The exosome was discovered more than a decade ago by Phil Mitchell and David Tollervey by its ability to trim the 3’end of yeast, S. cerevisiae, 5. 8S rRNA. In a historic account they laid out the events surrounding this identification and the subsequent birth of the research field. In the chapter by Kurt Januszyk and Christopher Lima the structural organization of eukaryotic exosomes and their evolutionary counterparts in bacteria and archaea are discussed in large part through presentation of structures.
