By way of its clear and logical structure, as well as abundant highresolution illustrations, this is a systematic survey of the players and pathways that control genome function in the mammalian cell nucleus. As such, this handbook and reference ties together recently gained knowledge from a variety of scientific disciplines and approaches, dissecting all major genomic events: transcription, replication, repair, recombination and chromosome segregation. A special emphasis is put on transcriptional control, including genome-wide interactions and non-coding RNAs, chromatin structure, epigenetics and nuclear organization. With its focus on fundamental mechanisms and the associated biomolecules, this will remain essential reading for years to come.

This volume reviews the latest research on the functional implications of nuclear, chromosomal and genomic organization and architecture on cell and organismal biology, and development and progression of diseases. The architecture of the cell nucleus and non-random arrangement of chromosomes, genes, and the non-membranous nuclear bodies in the three-dimensional (3D) space alters in response to the environmental, mechanical, chemical, and temporal cues. The changes in the nuclear, chromosomal, or genomic compaction and configuration modify the gene expression program and induce or inhibit epigenetic modifications. The intrinsically programmed rearrangements of the nuclear architecture are necessary for cell differentiation, the establishment of cell fate during development and maturation of tissues and organs including the immune, muscle, and nervous systems. The non-programmed changes in the nuclear architecture can lead to fragmentation of the nucleus and instability of the genome and thus cause cancer. Microbial and viral infections can lead to a clustering of centromeres, telomeres and ribosomal DNA and alter the properties of the nuclear membrane, allowing large immobile macromolecules to enter the nucleus. Recent advances in next-generation sequencing technologies combined with nucleus/chromosome conformation capture, super-resolution imaging, chromosomal contact maps methods, integrative modeling, and genetic approaches, are uncovering novel features and importance of nuclear, chromosomal and genomic architecture. This book is an interesting read for cell biologists, researchers studying the structure and function of chromosomes, and anyone else who wants to get an overview of the field of nuclear, chromosomal and genomic architecture.

The three-dimensional organization of the DNA inside the eukaryotic cell nucleus has emerged a critical regulator of genome integrity and function. Increasing evidence indicates that nuclear pore complexes (NPCs), the large protein channels that connect the nucleus to the cytoplasm, play a critical role in the establishment and maintenance of chromatin organization and in the regulation of gene activity. These findings, which oppose the traditional view of NPCs as channels with only one: the facilitation of nucleocytoplasmic molecule exchange, have completely transformed our understanding of these structures. This book describes our current knowledge of the role of NPCs in genome organization and gene expression regulation. It starts by providing an overview of the different compartments and structures of the nucleus and how they contribute to organizing the genome, then moves to examine the direct roles of NPCs and their components in gene expression regulation in different organisms, and ends by describing the function of nuclear pores in the infection and genome integration of HIV, in DNA repair and telomere maintenance, and in the regulation of chromosome segregation and mitosis. This book provides an intellectual backdrop for anyone interested in understanding how the gatekeepers of the nucleus contribute to safeguarding the integrity and function of the eukaryotic genome.

Nuclear Structure and Gene Expression assimilates the contributions of genome organization and of the components of the nuclear matrix to the control of DNA and RNA synthesis. Nuclear domains which accommodate DNA replication and gene expression are considered in relation to short-term developmental and homeostatic requirements as well as to long-term commitments to phenotypic gene expression in differentiated cells. Consideration is given to the involvement of nuclear structure in gene localization as well as to the targeting and concentration of transcription factors. Aberrations in nuclear architecture associated with and potentially functionally related to pathologies are evaluated. Tumor cells are described from the perspective of the striking modifications in both the composition and organization of nuclear components. Nuclear Structure and Gene Expression presents concepts as well as experimental approaches, which define functionality of nuclear morphology.* Mechanisms of interaction between nuclear structure and genes* Gene expression regulation by elements of the nuclear matrix* How nuclear structure exerts a regulatory effect on other aspects of cell function/physiology

Nuclear Architecture and Dynamics provides a definitive resource for (bio)physicists and molecular and cellular biologists whose research involves an understanding of the organization of the genome and the mechanisms of its proper reading, maintenance, and replication by the cell. This book brings together the biochemical and physical characteristics of genome organization, providing a relevant framework in which to interpret the control of gene expression and cell differentiation. It includes work from a group of international experts, including biologists, physicists, mathematicians, and bioinformaticians who have come together for a comprehensive presentation of the current developments in the nuclear dynamics and architecture field. The book provides the uninitiated with an entry point to a highly dynamic, but complex issue, and the expert with an opportunity to have a fresh look at the viewpoints advocated by researchers from different disciplines. - Highlights the link between the (bio)chemistry and the (bio)physics of chromatin - Deciphers the complex interplay between numerous biochemical factors at task in the nucleus and the physical state of chromatin - Provides a collective view of the field by a large, diverse group of authors with both physics and biology backgrounds

There is growing enthusiasm in the scientific community about the prospect of mapping and sequencing the human genome, a monumental project that will have far-reaching consequences for medicine, biology, technology, and other fields. But how will such an effort be organized and funded? How will we develop the new technologies that are needed? What new legal, social, and ethical questions will be raised? Mapping and Sequencing the Human Genome is a blueprint for this proposed project. The authors offer a highly readable explanation of the technical aspects of genetic mapping and sequencing, and they recommend specific interim and long-range research goals, organizational strategies, and funding levels. They also outline some of the legal and social questions that might arise and urge their early consideration by policymakers.

Functional Organization of The Nucleus

The nucleus guides the life processes of the cell by directing cellular reproduction, differentiation during development, and metabolism. The study of the structure and function of the nucleus along with its genetic material serves as the foundation for the science of genetics. Principles of Nuclear Structure and Function provides a comprehensive overview of the cell nucleus by illustrating the connection between function and the architecture of the nucleus. Richly illustrated throughout, each chapter includes an overview, detailed examples, summary points, references, and callout boxes highlighting methods and cutting-edge technology. The appendix provides a useful list of related Web sites. Some of the subjects reviewed within Principles of Nuclear Structure and Function include: * Nuclear structure, replication, damage, and repair * Regulation of gene expression * The cell cycle * Meiosis and recombination This timely volume presents functional studies within their proper structural context and is an informative profile of the cell and molecular biology in nuclei and chromatin. For those studying cell biology, along with molecular and cell biologists, geneticists, and reproductive biologists, Principles of Nuclear Structure and Function is a definitive resource.
