Genome Organization And Function In The Cell Nucleus

Presents an integrated view of the expression of bacterial genetic information, genome architecture and function, and bacterial physiology and pathogenesis This book blends information from the very latest research on bacterial chromosome and nucleoid architecture, whole-genome analysis, cell signaling, and gene expression control with well-known gene regulation paradigms from model organisms (including pathogens) to give readers a picture of how information flows from the environment to the gene, modulating its expression and influencing the competitive fitness of the microbe. Structure and Function of the Bacterial Genome explores the governance of the expression of the genes that make a bacterium what it is, and updates the basics of gene expression control with information about transcription promoter structure and function, the role of DNA as a regulatory factor (in addition to its role as a carrier of genetic information), small RNAs, RNAs that sense chemical signals, ribosomes and translation, posttranslational modification of proteins, and protein secretion. It looks at the forces driving the conservation and the evolution of the dynamic genome and offers chapters that cover DNA replication, DNA repair, plasmid biology, recombination, transposition, the roles of repetitive DNA sequences, horizontal gene transfer, the defense of the genome by CRISPR-Cas, restriction enzymes, Argonaute proteins and BREX systems. The book finishes with a chapter that gives an integrated overview of genome structure and function.  Blends knowledge of gene regulatory mechanisms with a consideration of nucleoid structure and dynamics Offers a 'DNA-centric' approach to considering transcription control Views horizontal gene transfer from a gene regulation perspective Assesses the opportunities and limitations of designing synthetic microbes or rewiring existing ones Structure and Function of the Bacterial Genome is an ideal book for graduate and undergraduate students studying microbial cell biology, bacterial pathogenesis, gene regulation, and molecular microbiology. It will also appeal to principal investigators conducting research on these and related topics and researchers in synthetic biology and other arms of biotechnology.

This book contains extremely detailed and informative content on structure and function of ligands, receptors, and signalling intermediates plus interactions … the extent of detail and appropriate referencing is impressive. –Microbiology Today, July 2009 «A very well-written book suitable for use as a reference or textbook for an undergraduate subject in cell signalling. For researchers interested in the molecular basis of cell signalling and how aberrant regulation of cell signalling proteins causes diseases, this is an excellent resource of biochemical and structural information.» –Australian Biochemist, August 2009 «From basics to details, this is an elegantly written and carefully edited book. The chapters on cell cycle control and oncogenesis are particularly fascinating and valuable to biomedical research. This is the book to have if you are interested in molecular mechanisms of signal transduction. It is a great introduction to the literature that will be welcomed by students and experts alike.» –Doody's, January 2009 This text is a concise and accessible introduction to the dynamic but complex field of signal transduction. Rather than simply cataloguing all signalling molecules and delineating every known pathway, this book aims to break signalling down into common elements and activities – the ‘nuts and bolts’ of cellular information exchange. With an emphasis on clarity of presentation throughout, the book teaches the basic principles focusing on a mature core of knowledge, providing students with a foundation of learning in this complex and potentially confusing subject. It also addresses the issue of variation in the numbering of key amino acids as well as featuring interaction with RasMol software, and exercises to aid understanding. An accessible introduction to the complex field of cell signalling Interacts with RasMol software – freely downloadable for viewing structures in 3D Includes exercises and clear instructions in the use of RasMol Well illustrated in full colour throughout Structure and Function in Cell Signalling is an invaluable resource to students across a range of life science degree programmes including biochemistry, cell and molecular biology, physiology, biomedicine and oncology. This book provides a clear, accessible introduction to this rapidly expanding field.

This book draws together contributions from cell and developmental biologists, structural biologists, geneticists and clinical scientists aimed at a better understanding of the cellular and molecular basis of these diseases. Topics include: How nuclear structure and location within a nucleus affect gene expression Chromatin organization and cell differentiation The nature of the interactions between the nuclear envelope and the cytoskeleton The extent to which the cytoskeleton mediates communication between the cell membrane and nucleus in regulating gene expression and whether disruption of such communication might underlie the disease processes It is hoped that a better understanding of the mechanisms leading to disease pathogenesis may ultimately lead to more rational and appropriate treatments.

The mapping of human genes is proceeding rapidly. Genes associated with specific inherited diseases are being identified, often providing insight into the molecular cause of the disease. At the moment, however, little consideration is being given to the variation present in different human populations. Variation in the Human Genome discusses methods of analysing population genetic data and how contemporary genetic heterogeneity arises during the evolution and migration of human populations. Specific disorders such as cystic fibrosis, beta-thalassaemia, fragile X, phenylketonuria and tumour development susceptibility are used to illustrate this genetic variability and mechanisms of gene mutation and evolution.

The transposable genetic elements, or transposons, as they are now known, have had a tumultuous history. Discovered in the mid-20th century by Barbara McClintock, they were initially received with puzzlement. When their genomic abundance began to be apparent, they were categorized as «junk DNA» and acquired the label of parasites. Expanding understanding of gene and genome organization has revealed the profound extent of their impact on both. Plant Transposons and Genome Dynamics in Evolution captures and distills the voluminous research literature on plant transposable elements and seeks to assemble the big picture of how transposons shape gene structure and regulation, as well as how they sculpt genomes in evolution. Individual chapters provide concise overviews of the many flavors of plant transposons and of their roles in gene creation, gene regulation, development, genome evolution, and organismal speciation, as well as of their epigenetic regulation. This volume is essential reading for anyone working in plant genetics, epigenetics, or evolutionary biology.

Self-Organization in Sensor and Actor Networks explores self-organization mechanisms and methodologies concerning the efficient coordination between intercommunicating autonomous systems.Self-organization is often referred to as the multitude of algorithms and methods that organise the global behaviour of a system based on inter-system communication. Studies of self-organization in natural systems first took off in the 1960s. In technology, such approaches have become a hot research topic over the last 4-5 years with emphasis upon management and control in communication networks, and especially in resource-constrained sensor and actor networks. In the area of ad hoc networks new solutions have been discovered that imitate the properties of self-organization. Some algorithms for on-demand communication and coordination, including data-centric networking, are well-known examples. Key features include: Detailed treatment of self-organization, mobile sensor and actor networks, coordination between autonomous systems, and bio-inspired networking. Overview of the basic methodologies for self-organization, a comparison to central and hierarchical control, and classification of algorithms and techniques in sensor and actor networks. Explanation of medium access control, ad hoc routing, data-centric networking, synchronization, and task allocation issues. Introduction to swarm intelligence, artificial immune system, molecular information exchange. Numerous examples and application scenarios to illustrate the theory. Self-Organization in Sensor and Actor Networks will prove essential reading for students of computer science and related fields; researchers working in the area of massively distributed systems, sensor networks, self-organization, and bio-inspired networking will also find this reference useful.

Diet and exercise have long been recognized as important components of a healthy lifestyle, as they have a great impact on improving cardiovascular and cerebrovascular functions, lowering the risk of metabolic disorders, and contributing to healthy aging. As a greater proportion of the world’s population is living longer, there has been increased interest in understanding the role of nutrition and exercise in long-term neurological health and cognitive function. Diet and Exercise in Cognitive Function and Neurological Diseases discusses the role and impact that nutrition and activity have on cognitive function and neurological health. The book is divided into two sections. The first section focuses on diet and its impact on neurobiological processes. Chapters focus on the impacts of specific diets, such as the Mediterranean, ketogenic and vegan diets, as well as the role of specific nutrients, fats, fatty acids, and calorie restriction on neurological health and cognitive function. The second section of the book focuses on exercise, and its role in maintaining cognitive function, reducing neuroinflammatory responses, regulating adult neurogenesis, and healthy brain aging. Other chapters look at the impact of exercise in the management of specific neurological disorders such Multiple Sclerosis and Parkinson’s Disease. Diet and Exercise in Cognitive Function and Neurological Diseases is a timely reference on the neurobiological interplay between diet and exercise on long-term brain health and cognitive function.
