Book Description
More than 40 years after the discovery of the nucleosome as the fun- mental unit of chromatin, the multifaceted problem of how variations in ch- matin structure affect the activity of the eukaryotic genome has not been solved. However, during the past few years research on chromatin structure and fu- tion has gained considerable momentum, and impressive progress has been made at the level of concept development as well as filling in crucial detail. The structure of the nucleosome has been visualized at unprecedented reso- tion. Powerful multisubunit enzymes have been identified that alter histone/ DNA interactions in ways that expose regulatory sequences to factors initi- ing and regulating such nuclear processes as transcription. Though the imp- tance of posttranslational modifications of histones, notably their acetylation, has long been known, the finding that a number of bona fide regulators increase transcription by acetylating nucleosomes has lent new support to the old idea that the process of gene regulation is intimately related to the nature of the chromatin environment. A wealth of nonhistone proteins contribute to a continuum of structures with distinct biochemical properties and varying degrees of DNA condensation. Perhaps the most important conclusion from a large number of studies is a fresh appreciation of the dynamic nature of chromatin structure, the built-in flexibility providing the basis for regulation.

Book Description
Toxicoepigenetics: Core Principles and Applications examines the core aspects of epigenetics, including chromatin biology, DNA methylation, and non-coding RNA, as well as fundamental techniques and considerations for studying each of these mechanisms of epigenetic regulation. Although its integration into the field of toxicology is in its infancy, epigenetics have taken center stage in the study of diseases such as cancer, diabetes, and neurodegeneration. Increasing the presence of epigenetics in toxicological research allows for a more in-depth understanding of important aspects of toxicology such as the role of the environment and lifestyle influencing the individual susceptibility to these effects and the trans-generational transmission of these health effects and susceptibilities. Methods chapters are included to help improve efficacy and efficiency of protocols in both the laboratory and the classroom. Toxicoepigenetics: Core Principles and Applications is an essential book for researchers and academics using epigenetics in toxicology research and study. - Introduces the fundamental principles and practices for understanding the role of the epigenome in toxicology - Presents the foundation of epigenetics for toxicologists with a broad range of backgrounds - Discusses the incorporation of epigenetics and epigenomics into current toxicological studies and interpretation of epigenetic data in toxicological applications

Book Description
The field of epigenetics has grown exponentially in the past decade, and a steady flow of exciting discoveries in this area has served to move it to the forefront of molecular biology. Although epigenetics may previously have been considered a peripheral science, recent advances have shown considerable progress in unraveling the many mysteries of nontraditional genetic processes. Given the fast pace of epigenetic discoveries and the groundbreaking nature of these developments, a thorough treatment of the methods in the area seems timely and appropriate and is the goal of Epigenetics Protocols. The scope of epigenetics is vast, and an exhaustive analysis of all of the techniques employed by investigators would be unrealistic. However, this TM volume of Methods in Molecular Biology covers three main areas that should be of greatest interest to epigenetics investigators: (1) techniques related to analysis of chromatin remodeling, such as histone acetylation and methylation; (2) methods in newly developed and especially promising areas of epigenetics such as telomere position effects, quantitative epigenetics, and ADP ribosylation; and (3) an updated analysis of techniques involving DNA methylation and its role in the modification, as well as the maintenance, of chromatin structure.

Book Description
In recent years, the field of epigenetics has grown significantly, driving new understanding of human developmental processes and disease expression, as well as advances in diagnostics and therapeutics. As the field of epigenetics continues to grow, methods and technologies have multiplied, resulting in a wide range of approaches and tools researchers might employ. Epigenetics Methods offers comprehensive instruction in methods, protocols, and experimental approaches applied in field of epigenetics. Here, across thirty-five chapters, specialists offer step-by-step overviews of methods used to study various epigenetic mechanisms, as employed in basic and translational research. Leading the reader from fundamental to more advanced methods, the book begins with thorough instruction in DNA methylation techniques and gene or locus-specific methylation analyses, followed by histone modification methods, chromatin evaluation, enzyme analyses of histone methylation, and studies of non-coding RNAs as epigenetic modulators. Recently developed techniques and technologies discussed include single-cell epigenomics, epigenetic editing, computational epigenetics, systems biology epigenetic methods, and forensic epigenetic approaches. Epigenetics methods currently in-development, and their implication for future research, are also considered in-depth. In addition, as with the wider life sciences, reproducibility across experiments, labs, and subdisciplines is a growing issue for epigenetics researchers. This volume provides consensus-driven methods instruction and overviews. Tollefsbol and contributing authors survey the range of existing methods; identify best practices, common themes, and challenges; and bring unity of approach to a diverse and ever-evolving field. - Includes contributions by leading international investigators involved in epigenetic research and clinical and therapeutic application - Integrates technology and translation with fundamental chapters on epigenetics methods, as well as chapters on more novel and advanced epigenetics methods - Written at verbal and technical levels that can be understood by scientists and students alike - Includes chapters on state-of-the-art techniques such as single-cell epigenomics, use of CRISPR/Cas9 for epigenetic editing, and epigenetics methods applied to forensics
