Acidic Proteins of the Nucleus focuses on the functional role of acidic nuclear proteins in differential gene expression. Historically, these proteins are referred to as acidic in nature because they are insoluble in dilute mineral acids and their amino acid composition shows a preponderance of acidic over basic amino acid residues. After an introduction to DNA-binding proteins and transcriptional control in prokaryotic and eukaryotic systems, the subsequent chapters describe various approaches for isolating, separating, and characterizing acidic nuclear proteins. The core chapters specifically cover the isolation, fractionation, and characterization of acidic nuclear phosphoproteins, and the role of these proteins in cell proliferation, cell differentiation, and cell cycle. The last two chapters address the role of acidic nuclear protein in binding steroid hormones and in gene regulation. Each chapter contains some previously unpublished work and provides recommendations for future research. This book will be a good reference background for researchers of acidic nuclear proteins.
Provides an advanced and up-to-date account of the theory of nuclear structure and discusses in considerable detail both the superfluid and collective models of the nucleus, in addition to earlier complementary models and theories. The book also examines other important topics such as the rotational and vibrational spectra of nuclei which have not previously been treated in such depth. To summarize, it covers a large amount of theoretical ground in one volume and attempts to fill a serious gap in the literature. Many problems are included
A graduate-level one-volume textbook and reference work on the structure and physics of atomic nuclei. Throughout this book the underlying emphasis is on how a nucleus is constituted through the interaction between the nucleons. The book is structured into three parts: the first part contains a detailed treatment of the two-nucleon force and of basic model-independent nuclear properties the second part discusses the experimental results of nuclear models and their bases in fundamental theory the third part deals in some detail with alpha-decay and fission.
Although our understanding of the structure and activities of the cell nucleus and of the nanomachines which it contains is increasing rapidly, much remains to be learned. The application and continuing development of the new, powerful biochemical and biophysical methodologies described here are essential in this quest. In The Nucleus, researchers from more than forty leading international laboratories describe state-of-the-art methods for isolating nuclei and their components and for studying their structure and activities, including some pathology-associated features. Volume I: Nuclei and Subnuclear Structures presents an overview of features of the intranuclear environment, followed by the most recent procedures for isolating nuclei from a wide range of cell types including muscle cells, yeast, oocytes, cells with polytene nuclei, Arabidopsis, trypanosomes, and dinoflagellates. The latest methods are described for isolating and working with nucleoli, constitutive heterochromatin, pathology-associated inclusions, and chromatin and for examining glycosylation, sumoylation, and ADP-ribosylation of nuclear proteins. Written in the highly successful Methods in Molecular BiologyTM series format, chapters contain lists of necessary materials and reagents, readily reproducible protocols, and tips for troubleshooting and avoiding known pitfalls. The Nucleus, Volume I: Nuclei and Subnuclear Structures is an essential reference for scientists who are working on our rapidly growing understanding of the cell nucleus and its activities.

Viruses cause numerous medically important diseases, affecting developing, developed, rich and poor alike. The diseases vary in severity, including chickenpox, smallpox, influenza, shingles, herpes, rabies, polio, Ebola, hanta fever, AIDS and the common cold, amongst others. Regardless of the type of tissue or organ affected, all viruses follow the same basic steps to infect host cells. Once in contact with host cells viruses release their genetic material into the cell followed by genome replication, production of viral proteins, assembly of the virus particle and egress from the infected cell. Viruses disrupt normal host cell processes in order to facilitate their own replication/assembly by re-directing cellular machinery for viral transcription, translation, assembly, release and by inhibiting antiviral responses. Regulated nuclear transport of macromolecules through the nuclear pore complex, the only means of transport across the nuclear membrane, is essential for normal cell function and an effective antiviral response. Many viruses disrupt or exploit the nucleocytoplasmic trafficking pathways in host cells. Cytoplasmic viruses exploit the host cell nucleocytoplasmic trafficking machinery to access nuclear functions and/or disrupt nuclear transport, while several DNA viruses use the trafficking pathways to enable export of their components into the cytoplasm; yet others complete their assembly within the nucleus and use nuclear export pathways to access the cytoplasm. Indeed, the many and varied interactions of viruses and viral proteins with nucleocytoplasmic trafficking components have been invaluable in pathway discovery. Importantly, mounting evidence suggests that these interactions play essential roles in virus replication/assembly and hence may be key to understanding pathophysiology of viral diseases. This Frontiers Research Topic is dedicated to the importance of nucleocytoplasmic trafficking to viral pathogenesis.
Viruses have limited genome-coding capacities and must therefore rely on their host cells to facilitate every step of the infection cycle from the replication of their genomes, transcription and translation of mRNAs to virus assembly. Aimed at virologists and cell biologists Viruses and the Nucleus provides a comprehensive and cohesive overview of this fascinating and fast moving field. It compares and contrasts the ways in which DNA viruses, retroviruses and RNA viruses interact with the host cell nucleus to bring about replication and how they subvert the host cell function to proliferate and survive. Written by a team of leading experts in the field, this multi-authored text begins with an introduction to the key nuclear process that effect virus biology including cell cycle, transcription, splicing and protein trafficking. It then goes on to explore the advances that have been made in understanding the ways in which specific viruses interact with nuclear sub-structures such as the nucleolus and ND10s, and the implications this interrelationship has for the cell cycle as a whole. Key Features Comprehensive cross disciplinary coverage of the interrelationship between cell biology and virology. Written by leading experts, this authorative book provides an up to date overview of this highly active field. Covers the latest research areas including virus interactions with sub-nuclear structures, virus protein trafficking into and out of the nucleus and subversion of host-cell function through specific nuclear interactions. Viruses and the Nucleus is an invaluable resource for students of virology, microbiology and cell biology as well as for those who work within the industry.
New techniques make it possible for investigators to examine and sometimes quantify various aspects of nuclear morphology and function; now they can derive clinically and biologically useful information about the nucleus. This book draws together a series of techniques which have been successfully applied to the study of the nucleus of tumour cells. These are of fundamental importance to researchers in tumour histopathology and medical oncology. Detailed reviews are given of various aspects of the morphology, ploidy and karyotypic status and function of the nuclei in the cells of tumours and preneoplastic lesions. Topics covered include nuclear morphology in tumour diagnosis, the ultrastructure of the nucleus, karyotypic analyses of solid tumours, flow cytometric assessment of nuclear ploidy and other parameters, histomorphometry of the nucleus, and in situ hybridisation.
Providing an essential brainstem relay for three cranial nerves, the NST coordinates highly complex sensory information. While other functions of the NST have received attention, its role in gustatory processing has received little. The first reference devoted exclusively to gustatory processing, The Role of the Nucleus of the Solitary Tract in Gustatory Processing offers an in-depth review of one of the most important central relay stations in the brain. Combining widely dispersed research into a comprehensive single volume, it presents a thorough historical background, documents the anatomy of the rostral nucleus of the solitary tract (rNST), and explores the properties of synaptic transmitters and neurons within that tract. The book examines the role of reflex activities and considers factors that influence how gustatory rNST neurons respond to taste stimuli. It describes the development and maturational changes the rNST undergoes and considers the challenge involved with identifying rNST neural circuits. The Role of the Nucleus of the Solitary Tract in Gustatory Processing brings together expert investigators who have contributed substantially to the current knowledge of the anatomy, physiology, and developmental biology of the solitary nucleus. This pertinent work serves as a standard reference for those involved in the field, providing ready access to past investigations and inviting practitioners to create new approaches that will advance knowledge about the central processing of gustatory information.
Written and edited by experts in the field, this volume includes contributions discussing the relationship between nuclear structure and function, the various nuclear bodies that have been identified, and the organization of the nuclear lamina and nuclear pore complex.
