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.

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

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 Cell Nucleus, Volume I reports the basic concepts of cell nucleus, including nuclear structure, the interaction between the nucleus and cytoplasm, and the chromatin. This volume first describes the nucleus’ morphological structures and relates these structures to its functions. It then discusses nuclear organization in plant cells; morphology and biochemistry of the slime mold nucleus; and structure, function, and properties of nuclear envelope. In addition, it addresses the molecular movements between nucleus and cytoplasm against a concentration gradient, presents experiments with animal cell heterokaryons, and explains the genome in specialized cells. It also explores the organization of the chromatin fiber; the human chromosome structure before and after banding; and the ultrastructure and function of heterochromatin and euchromatin.

The genome is more than a linear code as depicted by its DNA sequences as several interacting factors play a crucial role in shaping its organization and function. The complete sequences of a number of plant genomes and the recent advances of high-throughput technologies has fueled research efforts in the field of Plant Nuclear Biology unveiling numerous insights about the mechanisms underlying genome regulation. Genomic information is being integrated into molecular- and cellular-level mechanisms of the plant processes. A host of nuclear processes underlie key developmental processes as well as biotic and abiotic interactions. Non-coding RNAs have been increasingly recognized as players in gene expression and genome defense and integrity. However, in vivo, genomes exist as elaborate physical structures, and their functional properties are strongly determined by their cellular organization. Various types of subcellular structure have been identified in the nucleus, which are associated with transcription factors, RNA processing proteins and epigenetic regulators. Interestingly, these nuclear bodies display different behaviors in response to the environment. This book compiles a series of landmark discussions of the recent advances in plant nuclear biology research focusing in the functional relevance of the arrangement of genomes and nuclear processes that impact plant physiology and development.
