Volume 122 of Methods in Cell Biology describes modern tools and techniques used to study nuclear pore complexes and nucleocytoplasmic transport in diverse eukaryotic model systems (including mammalian cells, Xenopus, C. elegans, yeast). The volume enables investigators to analyze nuclear pore complex structure, assembly, and dynamics; to evaluate protein and RNA trafficking through the nuclear envelope; and to design in vivo or in vitro assays appropriate to their research needs. Beyond the study of nuclear pores and transport as such, these protocols will also be helpful to scientists characterizing gene regulation, signal transduction, cell cycle, viral infections, or aging. The NPC being one of the largest multiprotein complexes in the cell, some protocols will also be of interest for people currently characterizing other macromolecular assemblies. This book is thus designed for laboratory use by graduate students, technicians, and researchers in many molecular and cellular disciplines. Describes modern tools and techniques used to study nuclear pore complexes and nucleocytoplasmic transport in diverse eukaryotic model systems (mammalian cells, Xenopus, C. elegans, yeast) Chapters are written by experts in the field Cutting-edge material

Bidirectional traffic of macromolecules across the nuclear envelope is an active and essential transport process in all eukaryotic cells. Work on various model systems has led to a tremendous increase in our understanding of nuclear transport in recent years. This volume summarizes our current knowledge of protein and RNA transport into and out of the nucleus. It contains nine up-to-date reviews which cover various aspects of nucleocytoplasmic transport, including the structure and function of the nuclear pore complex, the role of soluble transport factors in protein and RNA transport, and the regulation of protein transport through the nuclear pore.

Dysfunction of nuclear-cytoplasmic transport systems has been associated with many human diseases. Thus, understanding of how functional this transport system maintains, or through dysfunction fails to maintain remains the core question in cell biology. In eukaryotic cells, the nuclear envelope (NE) separates the genetic transcription in the nucleus from the translational machinery in the cytoplasm. Thousands of nuclear pore complexes (NPCs) embedded on the NE selectively mediate the bidirectional trafficking of macromolecules such as RNAs and proteins between these two cellular compartments. In this book, the authors integrate recent progress on the structure of NPC and the mechanism of nuclear-cytoplasmic transport system in vitro and in vivo.

In eukaryotic cells, the nuclear genome and its transcriptional apparatus is separated from the site of protein synthesis by the nuclear envelope. Thus, a constant flow of proteins and nucleic acids has to cross the nuclear envelope in both directions. This transport in and out of the nucleus is mediated by nuclear pore complexes (NPCs) and occurs in an energy and signal-dependent manner. Thus, nucleocytoplasmic translocation of macro molecules across the nuclear envelope appears to be a highly specific and regulated process. Viruses that replicate their genome in the cell nucleus are therefore forced to develop efficient ways to deal with the intracellulZlr host cell transport machinery. Historically, investigation of Polyomavirus replication allowed identification ofsequences that mediate nuclear import, which led subsequently to our detailed understanding of the cellular factors that are involved in nuclear import. Transport ofmacromolecules in the opposite direction, however, is less well understood. The investigation of retroviral gene expression in recent years pro vided the first insights into the cellular mechanisms that regulate nuclear export. In particular, the detailed dissection of the function of the human immunodeficiency virus type I (HIV-I) Rev trans-activator protein identified CRMI, as a hona fide nuclear export receptor. CRM I appears to be involved in the nucleocytoplasmic translocation of the vast majority of viral and cellular proteins that have subsequently been found to contain a Rev-type leucine-rich nuclear export signal (NES).

Chromatin Regulation and Dynamics integrates knowledge on the dynamic regulation of primary chromatin fiber with the 3D nuclear architecture, then connects related processes to circadian regulation of cellular metabolic states, representing a paradigm of adaptation to environmental changes. The final chapters discuss the many ways chromatin dynamics can synergize to fundamentally contribute to the development of complex diseases. Chromatin dynamics, which is strategically positioned at the gene-environment interface, is at the core of disease development. As such, Chromatin Regulation and Dynamics, part of the Translational Epigenetics series, facilitates the flow of information between research areas such as chromatin regulation, developmental biology, and epidemiology by focusing on recent findings of the fast-moving field of chromatin regulation. Presents and discusses novel principles of chromatin regulation and dynamics with a cross-disciplinary perspective Promotes crosstalk between basic sciences and their applications in medicine Provides a framework for future studies on complex diseases by integrating various aspects of chromatin biology with cellular metabolic states, with an emphasis on the dynamic nature of chromatin and stochastic principles Integrates knowledge on the dynamic regulation of primary chromatin fiber with 3D nuclear architecture, then connects related processes to circadian regulation of cellular metabolic states, representing a paradigm of adaptation to environmental changes
