The ability of a single genome to give rise to hundreds of functionally distinct cell type programs is in itself remarkable. Pioneering studies over the past few decades have demonstrated that this plasticity is retained throughout development, a phenomenon of epigenetic programming and reprogramming that remains one of the most fascinating areas of modern biology, with major relevance to human health and disease. This book presents the basic biology involved, including key mechanistic insights into this rapidly growing field.

The view “It’s all in our genes and we cannot change it” developed in the past 150 years since Gregor Mendel’s experiments with flowering pea plants. However, there is a special form of genetics, referred to as epigenetics, which does not involve any change of our genes but regulates how and when they are used. In the cell nucleus our genes are packed into chromatin, which is a complex of histone proteins and genomic DNA, representing the molecular basis of epigenetics. Our environment and lifestyle decisions influence the epigenetics of our cells and organs, i.e. epigenetics changes dynamically throughout our whole life. Thus, we have the chance to change our epigenetics in a positive as well as negative way and present the onset of diseases, such a type 2 diabetes or cancer. This textbook provides a molecular explanation how our genome is connected with environmental signals. It outlines that epigenetic programming is a learning process that results in epigenetic memory in each of the cells of our body. The central importance of epigenetics during embryogenesis and cellular differentiation as well as in the process of aging and the risk for the development of cancer are discussed. Moreover, the role of the epigenome as a molecular storage of cellular events not only in the brain but also in metabolic organs and in the immune system is described. The book represents an updated but simplified version of our textbook “Human Epigenomics” (ISBN 978-981-10-7614-8). The first five chapters explain the molecular basis of epigenetics, while the following seven chapters provide examples for the impact of epigenetics in human health and disease.

Much of the diversity we observe in cellular and organismal phenotypes can be attributed to epigenetic and genetic variation. DNA provides the instructions for life, while epigenetic modifications regulate which parts of the genetic information contained in DNA can be read out in a given cell and how this information is interpreted. In recent years, epigenetic and genetic variation has been profiled on a large scale with sequencing-based assays, generating many datasets to be explored. In this thesis, I present three projects which apply computational techniques to identify and characterize epigenetic mechanisms that may contribute to the regulation of phenotypic variance. First, we mine a dataset charactering the epigenomes of diverse cell types in order to discover signatures of adult stem cell differentiation. We identify a novel marker of the multipotent state, a chromatin state characterized by the histone marks H3K36me3 and H3K9me3, and describe biological processes that may be linked to the loss of this chromatin state in fully differentiated cell types. Next, I present what we learned from profiling the epigenetic state of cells before and after transplantation into Xenopus oocytes, a process that transcriptionally reprograms the cells. This analysis elucidates how the initial epigenetic state of a cell influences the success of cellular reprogramming and identifies transcription factors that help regulate this process. Finally, we integrate studies measuring the effects of genetic variants on disease with studies measuring the effects of genetic variants on transcriptional and epigenetic activity. This identifies specific mechanisms underlying disease processes, and demonstrates that transcriptional and epigenetic mechanisms may independently contribute to disease pathogenesis. Together, these projects demonstrate the biological insights that can be gained from epigenetic profiling, and expand our understanding of the potential effects of epigenetic modifications.

Epigenetic Gene Expression and Regulation reviews current knowledge on the heritable molecular mechanisms that regulate gene expression, contribute to disease susceptibility, and point to potential treatment in future therapies. The book shows how these heritable mechanisms allow individual cells to establish stable and unique patterns of gene expression that can be passed through cell divisions without DNA mutations, thereby establishing how different heritable patterns of gene regulation control cell differentiation and organogenesis, resulting in a distinct human organism with a variety of differing cellular functions and tissues. The work begins with basic biology, encompasses methods, cellular and tissue organization, topical issues in epigenetic evolution and environmental epigenesis, and lastly clinical disease discovery and treatment. Each highly illustrated chapter is organized to briefly summarize current research, provide appropriate pedagogical guidance, pertinent methods, relevant model organisms, and clinical examples. Reviews current knowledge on the heritable molecular mechanisms that regulate gene expression, contribute to disease susceptibility, and point to potential treatment in future therapies Helps readers understand how epigenetic marks are targeted, and to what extent transgenerational epigenetic changes are instilled and possibly passed onto offspring Chapters are replete with clinical examples to empower the basic biology with translational significance Offers more than 100 illustrations to distill key concepts and decipher complex science

Growing evidence suggests that epigenetic mechanisms play a central role in stem cell biology and are vital for determining gene expression during cellular differentiation and governing mammalian development. In Stem Cell Epigenetics, leading international researchers examine how chromatin regulation and bona fide epigenetic mechanisms underlie stem cell renewal and differentiation. Authors also explore how the diversity of cell types, including the extent revealed by single cell omic approaches, is achieved, and how such processes may be reversed or managed via epigenetic reprogramming. Topics discussed include chromatin in pluripotency, stem cells and DNA methylation, histone modifications in stem cells and differentiation, higher-order chromatin conformation in pluripotent cells, stem cells and cancer, epigenetics and disease modeling, brain organoids from pluripotent cells, transcriptional regulation in stem cells and differentiation, non-coding RNAs in pluripotency and early differentiation, and diseases caused by epigenetic alterations in stem cells. Additionally, the book discusses the potential implementation of stem cell epigenetics in drug discovery, regenerative medicine, and disease treatment. Stem Cell Epigenetics will provide researchers and physicians with a state-of-the-art map to orient across the frontiers of this fast-evolving field. Analyzes the role of epigenetics in embryonic stem cell regulation Indicates the epigenetic mechanisms involved in stem cell differentiation and highlights modifications and misregulations that may result in disease pathogenesis Examines the potential applications of stem cell epigenetics in therapeutic disease interventions and regenerative medicine, providing a foundation for researchers and physicians to bring this exciting and fast-evolving field into a clinical setting Features chapter contributions by leading international experts
