Book Description
Regulation of gene expression is vital for proper growth and prevention of disease states. In eukaryotes this regulation occurs in the context of chromatin which creates an inherent barrier for the binding of trans-acting factors, such as transcription factors and RNA polymerase. This dissertation focuses on the role of transcriptional activators and chromatin remodeling coactivators in the regulation of the repressible acid phosphatase gene PHO5. Our studies show that histone methylation at lysine 4 of histone H3 is required for the full repression of PHO5and GAL1-10. We show that bromodomains, a domain conserved in chromatin remodeling coactivators, may function to stabilize binding. Finally, we present a strategy using DNA methyltransferases as in vivo probes to detect DNA-protein interactions and examine chromatin structure. We extend this strategy to zinc-finger proteins which can be engineered to bind to any desired DNA sequence as a means of targeting methylation with potential use in epigenetic silencing.

Book Description
Since publication of the first edition in 1995, there have been significant advances and understanding of chromatin structure and its relation to gene expression. These include a high-resolution structure of the nucleosome core, discovery of the enzymes and complexes that mediate histone acetylation and deacetylation, discovery of novel ATP-dependent chromatin remodeling complexes, new insights into nuclear organization and epigenetic silencing mechanisms. In light of these advances, Chromatin Structure and Gene Expression (2ed.) includes updated chapters and additional material that introduce new concepts in the process of gene regulation in chromatin.

Book Description
Written in an informal and accessible style, Chromatin and Gene Regulation enables the reader to understand the science of this rapidly moving field. Chromatin is a fundamental component in the network of controls that regulates gene expression. Many human diseases have been linked to disruption of these control processes by genetic or environmental factors, and unravelling the mechanisms by which they operate is one of the most exciting and rapidly developing areas of modern biology. Chromatin is central both to the rapid changes in gene transcription by which cells respond to changes in their environment and also to the maintenance of gene expression patterns from one cell generation to the next. This book will be an invaluable guide to undergraduate and postgraduate students in the biological sciences and all those with an interest in the medical implications of aberrant gene expression.

Book Description
The term "chromatin remodelling" is widely used to describe changes in chromatin structure which is controlled by histone-modifying enzymes, chromatin remodelling complexes, non-histone DNA-binding proteins and noncoding RNAs. Many human diseases such as cancer, various genetic syndromes, autism and infectious disease have been linked to the disruption of these control processes by genetic, environmental or microbial factors. Therefore, to unravel the mechanisms by which they operate is one of the most exciting and rapid developing fields of modern biology and will contribute to new ways in treatment of these diseases. The chapters in this book will focus on recent advances in our understanding of the mechanisms that govern the dynamic structural of chromatin, thereby providing important insights into gene regulation, DNA repair, and human diseases.

Book Description
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
