While there has been an increasing number of books on various aspects of epigenetics, there has been a gap over the years in books that provide a comprehensive understanding of the fundamentals of chromatin. Chromatin is the combination of DNA and proteins that make up the genetic material of chromosomes. Its primary function is to package DNA to fit into the cell, to strengthen the DNA to prevent damage, to allow mitosis and meiosis, and to control the expression of genes and DNA replication. The audience for this book is mainly newly established scientists and graduate students. Rather than going into the more specific areas of recent research on chromatin the chapters in this book give a strong, updated groundwork about the topic. Some the fundamentals that this book will cover include the structure of chromatin and biochemistry and the enzyme complexes that manage it.

Download Chromatin Structure and Dynamics Book in PDF, ePub and Kindle
Biological processes that replicate, preserve and use the genetic information encoded in DNA must operate in the context of chromatin, a highly organized complex of DNA and proteins. These proteins do not merely package the DNA in the tiny volume of the nucleus, but impart the structure the ability to change according to the requirements of the specific process the DNA is involved in. Moreover, chromatin structure is used by the cell to control the activity of DNA. In this volume the basics of chromatin structure and dynamics are presented by established experts in the field.

Download Chromatin Regulation and Dynamics Book in PDF, ePub and Kindle
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

Download RESOLVING GENOME-WIDE VIEWS OF CHROMATIN STRUCTURE TO IDENTIFY FUNDAMENTAL PRINCIPLES OF GENOME ORGANIZATION Book in PDF, ePub and Kindle
Chromatin, the collection of DNA and proteins found in eukaryotic nuclei, is organized into a distinct structure to facilitate the compaction of genomic DNA. Chromatin structure is highly conserved across eukaryotic species and the organization of chromatin is known to have far-reaching implications on the accessibility and functionality of genetic information stored in nucleotide sequences. The purpose of this research is to improve our understanding of the global principles controlling chromatin structure. Work in this thesis utilizes the genetic model of Saccharomyces cerevisiae because of its high experimental tractability, strong conservation of eukaryotic transcription machinery, and extensive genome annotation. This thesis begins with a study defining the technical biases present in genome-wide chromatin mapping experiments and outlining the development and validation of an improved methodology that standardizes the collection and analysis of genome-wide maps of chromatin structure. This standardized collection and analysis of chromatin structures ultimately enables unbiased comparisons between genome-wide chromatin states, which help to expand our understanding of chromatin biology. Accordingly, global principles of genome organization are explored by using this improved methodology to map and compare genome-wide chromatin structures in various experimentally perturbed chromatin states. First, genome-wide chromatin structures are compared in the presence and absence of a conserved transcriptional repressor protein that is known to act through chromatin, Tup1p. Analysis of wild-type and tup1D; chromatin structures enabled identification of a dominant role for Tup1p in establishing nucleosome positioning and occupancy at -1 and -2 promoter nucleosomes directly upstream of transcription start sites as part of is repressive mechanism. Additionally, analysis of chromatin organization at Tup1-regulated genes suggests a link between Tup1 regulation and transcriptional plasticity, whereby more open promoter structures are targeted by a larger number of regulatory factors with distinct patterns, to enable more variable gene expression across different environments. Finally, genome-wide chromatin structures are mapped and compared following an experimental depletion of nucleosomes to explore the role of histone dosage in chromatin organization. Structural responses to nucleosome depletion suggest alternative mechanisms for the establishment of the 5' barrier against which nucleosomes are packed and the spacing between 5' nucleosomes. Packing barriers at the 5' ends of genes are established through a mechanism that is sensitive to histone dosage, whereas spacing between 5' nucleosomes is maintained more resiliently in response to nucleosome depletion, suggesting a histone dose-independent mechanism. Loss of nucleosomes also occurs in a non-random fashion and with distinct structural changes that appear to relate to differences in transcriptional machinery and promoter elements at gene classes. Overall, this behavior is consistent with the active placement of nucleosomes surrounding transcription start sites and suggests that statistical packing principles, once thought to organize a large portion of the genome, may not be as prominent.
