The regulation of gene expression in many biological processes involves epigenetic mechanisms. In this new volume, 24 chapters written by experts in the field discuss epigenetic effects from many perspectives. There are chapters on the basic molecular mechanisms underpinning epigenetic regulation, discussion of cellular processes that rely on this kind of regulation, and surveys of organisms in which it has been most studied. Thus, there are chapters on histone and DNA methylation, siRNAs and gene silencing; X-chromosome inactivation, dosage compensation and imprinting; and discussion of epigenetics in microbes, plants, insects, and mammals. The last part of the book looks at how epigenetic mechanisms act in cell division and differentiation, and how errors in these pathways contribute to cancer and other human diseases. Also discussed are consequences of epigenetics in attempts to clone animals. This book is a major resource for those working in the field, as well as being a suitable text for advanced undergraduate and graduate courses on gene regulation.

The field of epigenetics has gained great momentum in recent years and is now a rapidly advancing field of biological and medical research. Epigenetic changes play a key role in normal development, as well as in disease. The editor of this book has assembled top-quality scientists from diverse fields of epigenetics to produce a major new volume on current epigenetics research. The molecular mechanisms and biological processes in which epigenetic modifications play a primordial role are described in detail. The first seven chapters describe the different biological mechanisms of the epigenetic machinery including: DNA methylation, histone tails, chromatin structure, nucleosome occupancy, Polycomb group proteins, siRNAs, and miRNAs. The following chapters cover the epigenetic systems of plants, the epigenetic profile of embryonic stem cells, cell differentiation, imprinting marks, and random X chromosome inactivation. Further chapters deal with epigenetics in relation to cancers, premature aging, longevity, and the developmental origins of disease. The final chapter describes the fascinating potential transfer of epigenetic information across generations. This up-to-date volume is a major resource for those working in the field, and will stimulate readers of all levels to dive into the fascinating and fast moving field of epigenetics. The book's readership will include epigeneticists, cancer researchers, geneticists, molecular biologists, developmental scientists, cell biologists, biotechnologists, biochemists, and pharmaceutical and biotechnology companies.

The concept of epigenetics has been known about since the 1940s, but it is only in the last 10 years that research has shown just how wide ranging its effects are. It is now a very widely-used term, but there is still a lot of confusion surrounding what it actually is and does. Epigenetics is a new textbook that brings together the structure and machinery of epigenetic modification, how epigenetic modification controls cellular functions, and the evidence for the relationship between epigenetics and disease. It is a valuable source of information about all aspects of the subject for undergraduate students, graduate students, and professionals.

The exploding field of epigenetics is challenging the dogma of traditional Mendelian inheritance. Epigenetics plays an important role in shaping who we are and contributes to our prospects of health and disease. While early epigenetic research focused on plant and animal models and in vitro experiments, population-based epidemiologic studies increasingly incorporate epigenetic components. The relevance of epigenetic marks, such as DNA methylation, genomic imprinting, and histone modification for disease causation has yet to be fully explored. This book covers the basic concepts of epigenetic epidemiology, discusses challenges in study design, analysis, and interpretation, epigenetic laboratory techniques, the influence of of age and environmental factors on shaping the epigenome, the role of epigenetics in the developmental origins hypothesis, and provides the state of the art on the epigenetic epidemiology of various health conditions including childhood syndromes, cancer, infectious diseases, inflammation and rheumatoid arthritis, asthma, autism and other neurodevelopmental disorders, psychiatric disorders, diabetes, obesity and metabolic disorders, and atherosclerosis. With contributions from: Peter Jones, Jean-Pierre Issa, Gavin Kelsey, Robert Waterland, and many other experts in epigenetics!

What lies at the heart of neuronal plasticity? Accumulating evidence points to epigenetics. This word originally indicated potentially heritable modifications in gene expression that do not involve changes in DNA sequence. Today this definition is much less strict, and epigenetic control is thought to include DNA methylation, histone modifications, histone variants, microRNA metabolic pathways and non-histone proteins modifications. Thus, while neuronal plasticity is rightly thought to be intimately associated to genomic control, it is critical to appreciate that there is much more to the genome than DNA sequence. Recent years have seen spectacular advances in the field of epigenetics. These have attracted the interest of researchers in many fields and evidence connecting epigenetic regulation to brain functions has been accumulating. Neurons daily convert a variety of external stimuli into rapid or long-lasting changes in gene expression. A variety of studies have centered on the molecular mechanisms implicated in epigenetic control and how these may operate in concert. It will be critical to unravel how specificity is achieved. Importantly, specific modifications seem to mediate both developmental processes and adult brain functions, such as synaptic plasticity and memory. Many aspects of the research in neurosciences and endocrinology during the upcoming decade will be dominated by the deciphering of epigenetic control. This book constitutes a compendium of the most updated views in the field.

Recent advances in epigenetic research as well as the development of exciting new technologies have helped greatly in unraveling the many mysteries of nontraditional genetic processes. In Epigenetics Protocols, hands-on researchers describe state-of-the-art methods for epigenetic analysis, including recent breakthrough techniques that have great potential in the rapidly expanding field of non-Mendelian genetics. The authors provide techniques for the analysis of chromatin remodeling, such as histone acetylation and methylation. In addition, methods in newly developed and especially promising areas of epigenetics, such as telomere position effects, quantitative epigenetics, and ADP ribosylation are covered. There is also an updated analysis of techniques involving DNA methylation and its role in the modification, as well as the maintenance, of chromatin structure. Of special interest are potentially revolutionary techniques. These include methods for determining changes in native chromatin, methods of microarray analysis applied to epigenetics, and methylation-sensitive single-strand conformation techniques. The methods are suitable not only for studying fundamental biological processes, but also for investigating possible therapeutic interventions and such diseases as cancer. The protocols follow the successful Methods in Molecular BiologyTM series format, each one offering step-by-step laboratory instructions, an introduction outlining the principle behind the technique, lists of the necessary equipment and reagents, and tips on troubleshooting and avoiding known pitfalls. Comprehensive and easy to use, Epigenetics Protocols offers investigators readily reproducible techniques that will further promote progress in this critically important field.

Epigenetics refers to heritable patterns of gene expression which do not depend on alterations of genomic DNA sequence. This book provides a state-of-the-art account of a few selected hot spots by scientists at the edge in this extremely active field. It puts special emphasis on two main streams of research. One is the role of post-translational modifications of proteins, mostly histones, on chromatin structure and accessibility. The other one deals with parental genomic imprinting, a process which allows to express a few selected genes from only one of the parental allele while extinguishing the other.

This book provides a broad and rich outline of the epigenetic mechanisms involved in cancer progression and the generation of metastasis. It describes the tumor suppressor genes undergoing transcriptional silencing by CpG island promoter hypermethylation in the different tumor types of the human anatomy and their association with tumoral behaviour. It also provides a comprehensive insightful look at the molecular players involved in DNA methylation, histone modification and chromatin remodelling complexes causing epigenetic lesions linked to the metastasic phenotypes. Finally, it explains how epigenetic lesions associated with cancer spreading can be targeted using new and potent chemotherapy drugs. The book is a state-of-the-art reference to all scientific researchers and clinicians interested in the understanding of the biological processes leading to tumor dissemination and to those that are keen to translate this knowledge to a better management of cancer patients. Each contributor is a specialist in their epigenetic area and their joint effort has created a unique view of the DNA methylation, histone and chromatin changes that define cancer metastasis.
