Book Description
Cells possess a wealth of posttranscriptional control mechanisms that impact on every conceivable aspect of the life of an mRNA. These processes are intimately intertwined in an almost baroque manner, where promoter context influences the recruitment of splicing factors, where the majority of pre-mRNAs undergo alternative splicing, and where proteins deposited during nuclear processing impact distal cytoplasmic processing, translation, and decay. If there is a unifying theme to mRNA Processing and Metabolism: Methods and Protocols, it is that mRNA processing and metabolism are integrated processes. Many of the techniques used to study mRNA have been described in a previous volume of this series (RNA–Protein Interaction Protocols, Susan Haynes, ed.) and specialized methods journals. In selecting topics for mRNA Processing and Metabolism: Methods and Protocols, I sought input on new and novel techniques and approaches that build on this foundation using technological advances in microscopy, whole genome sequencing, microarrays, mass spectrometry, fluorescent detection methodologies, and RNA interference. I have tried not to bias this book toward any single model organism, and approaches described in the various chapters use yeast, Drosophila, Xenopus, mice, plants, and cultured mammalian cells.

Book Description
The eukaryotic gene expression pathway involves a number of interlinked steps, with messenger RNA (mRNA) being the key intermediate. The precursor mRNA is transcribed from DNA, processed by removal of introns and addition of the cap structure and the poly(A) tail. The mature mRNA is then exported to the cytoplasm where it is translated into protein and finally degraded. In this process, mRNA is associated with RNA-binding proteins forming ribonucleoprotein complexes, whose protein content evolves throughout the lifetime of the mRNA. While the complexity of eukaryotic gene expression allows the production of proteins to be controlled at many levels, it also makes the process vulnerable to errors. Although eukaryotic cells have evolved elaborate mRNA quality control mechanisms that ensure the fidelity of gene expression, some defects are not detected, thus affecting mRNA metabolism. This condition plays a fundamental role in the pathogenesis of several disease processes, such as neurodegeneration and oncogenesis. Besides, exciting recent data have shown that cellular RNAs can be modified post-transcriptionally via dynamic and reversible chemical modifications, the so-called epitranscriptome. These modifications can alter mRNA structure, being able to modulate different steps of the mRNA metabolism that can be associated with various human diseases, such as systemic lupus erythematosus and cancer. This book provides a collection of novel studies and hypotheses aimed to define the pathophysiological consequences of altered mRNA metabolism events in human cells, and is written for a wide spectrum of readers in the field of gene expression regulation. The last chapter highlights how the discovery of disease-causing defects (or modifications) in mRNA can provide a variety of therapeutic targets that can be used for the development of new RNA-based therapeutics. Hopefully, it may also contribute to inspire the drug-developing scientific community.

Book Description
This volume focuses on mitochondrial RNA metabolism, emphasizing recent discoveries and technological advances in this fast moving area that increase our understanding of mitochondrial gene function. Topics addressed include the interplay of mitochondria with the nucleus and cytosol, structure-function connections, and relevance to human disease. Mitochondria are the powerhouses of the cell, and a great deal is known about mitochondrial energy metabolism. Less well known is the plethora of amazing mechanisms that have evolved to control expression of mitochondrial genomes. Several RNA processes and machineries in protozoa, plants, flies and humans are discussed, including: transcription and RNA polymerase mechanism; tRNA processing of 5′ and 3′ ends; mRNA maturation by nucleotide insertion/deletion editing and by RNA splicing; mRNA stability; and RNA import. Specialized factors and ribonucleoproteins (RNPs) examined include pentatricopeptide repeat (PPR) proteins, RNase P, polymerases, helicases, nucleases, editing and repair enzymes. Remarkable features of these processes and factors are either not found outside mitochondria, differ substantially among eukaryotic lineages, or are unique in biology.

Book Description
mRNA METABOLISM & POST-TRANSCRIPTIONAL GENE REGULATION Edited by Joe B. Harford and David R. Morris Gene expression is a process that begins with the transcription ofDNA to an RNA messenger (mRNA), which is then translated into aprotein. Historically, attention has been focused on the regulationof RNA synthesis (transcription); however, there is a growingrecognition of and appreciation for the importance of the manyregulatory mechanisms that take place after RNA synthesis has beencompleted. mRNA Metabolism and Post-Transcriptional Gene Regulation is thefirst comprehensive overview of the various modes of generegulation that exist post-transcriptionally. Collecting studies bysome of the top researchers in the field, this volume provides bothan up-to-date review of the complex "life" of an mRNA molecule andan introduction to current work on the diversity of mechanisms ofpost-transcriptional reactions. Topics covered include: * RNA structure * Mammalian RNA editing * RNA export from the nucleus * The fundamentals of translation initiation * Control of mRNA decay in plants * mRNA metabolism and cancer * Control of mRNA stability during herpes simplex virus infection * Regulation of mRNA expression in HIV-1 and other complexretroviruses * Nucleases * RNA localization A timely contribution to the understanding of genetic regulatorymechanisms, mRNA Metabolism and Post-Transcriptional GeneRegulation provides a basis from which potential therapeuticstrategies may be developed. This book will be of vital interest tocell and molecular biologists at all levels, from graduate studentsto senior investigators, clinical researchers, and professionals inthe pharmaceutical and biotechnology industries.

Book Description
This is the second edition of a very well received book that details how the sumoylation system functions and how it modulates numerous cellular activities. SUMO is a post-translational modifier in the ubiquitin super-family that has gained recognition over the last twenty years as an essential and prevalent regulatory molecule. Individual chapters explore the biochemistry, molecular biology, and cell biology of the sumoylation system and its substrate proteins. The book is divided into three themed parts: Molecular Functions (I), Cell Growth Regulation (II), and Diseases (III). Parts I and II focus on the contribution of sumoylation to cellular activities in both the nuclear and cytoplasmic compartments. The nuclear activities covered include nucleic acid metabolism (both RNA and DNA), chromosome structure and replication, and nucleocytoplasmic transport. Cytoplasmic processes presented include regulation of membrane ion channels, general metabolism, and apoptotic signalling. Topics in Part III include the role of sumoylation in developmental abnormalities (craniofacial and cardiovascular), diabetes, neurodegenerative diseases, cancer, and infections with viruses and bacteria. Each of the corresponding chapter authors is an active researcher who has made significant contributions to understanding sumoylation. This second edition provides updates and revisions to most of the original chapters plus adds six new chapters to address important developing areas of sumoylation research. This volume is intended for a scientific audience from undergraduates to independent researchers. The content will serve as both a solid introduction for the novice reader and an in depth treatment for the advanced scholar.

Book Description
Concepts of Biology is designed for the single-semester introduction to biology course for non-science majors, which for many students is their only college-level science course. As such, this course represents an important opportunity for students to develop the necessary knowledge, tools, and skills to make informed decisions as they continue with their lives. Rather than being mired down with facts and vocabulary, the typical non-science major student needs information presented in a way that is easy to read and understand. Even more importantly, the content should be meaningful. Students do much better when they understand why biology is relevant to their everyday lives. For these reasons, Concepts of Biology is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand.We also strive to show the interconnectedness of topics within this extremely broad discipline. In order to meet the needs of today's instructors and students, we maintain the overall organization and coverage found in most syllabi for this course. A strength of Concepts of Biology is that instructors can customize the book, adapting it to the approach that works best in their classroom. Concepts of Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand--and apply--key concepts.
