Book excerpt: Industrial melanism of peppered moths is a famous case of what has often been described as: 'Darwinian evolution via selection in action'. This little book offers an alternative, yet light hearted approach, to this rather controversial topic, based upon the most recent and cutting-edge biological scientific discoveries of our present time. This alternative explanation gives us an insight into past evolutionary speciation (how one species becomes another) in real terms, hence the use of an epigenetic caterpillar analogy as a caterpillar via metamorphosis, turns into a butterfly: a distinctly different animal, yet, irrespective of whether it is in its caterpillar or a flying insect form, its genes remain identical. This is explicable by environmentally-driven epigenetic processes as it is the change in the expression of the genes that are triggered by the environment, which can cause a profound and rapid change in the species and these changes can be inherited. The genes themselves or the DNA sequence do not alter. Therefore, the epigenetics form of evolution is at complete odds with the Neo-Darwinian explanation of the cause of the variation seen in peppered moths and indeed, evolutionary change (speciation) in general, as epigenetic means that it operates above the genes, (the epigenetic caterpillar) and the really interesting part is that in principle, Charles Darwin would have agreed with this environmentally-driven epigenetic explanation.

Download or read book The Epigenetics Revolution written by Nessa Carey and published by Columbia University Press. This book was released on 2013-10-01 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: Epigenetics can potentially revolutionize our understanding of the structure and behavior of biological life on Earth. It explains why mapping an organism’s genetic code is not enough to determine how it develops or acts and shows how nurture combines with nature to engineer biological diversity. Surveying the twenty-year history of the field while also highlighting its latest findings and innovations, this volume provides a readily understandable introduction to the foundations of epigenetics. Nessa Carey, a leading epigenetics researcher, connects the field’s arguments to such diverse phenomena as how ants and queen bees control their colonies; why tortoiseshell cats are always female; why some plants need cold weather before they can flower; and how our bodies age and develop disease. Reaching beyond biology, epigenetics now informs work on drug addiction, the long-term effects of famine, and the physical and psychological consequences of childhood trauma. Carey concludes with a discussion of the future directions for this research and its ability to improve human health and well-being.
Download or read book Human Epigenetics How Science Works written by Carsten Carlberg and published by Springer Nature. This book was released on 2019-09-24 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Epigenetic Modifications and Viral Infections written by Silvia Carolina Galvan and published by Frontiers Media SA. This book was released on 2015-07-09 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: Epigenetics is defined as the study of modifications of the genome, heritable during cell division that does not involve changes in DNA sequences. Up to date, epigenetic modifications involve at least three general mechanisms regulating gene expression: histone modifications, DNA methylation, and non-coding RNAs (ncRNAs). For the past two decades, an explosion in our interest and understanding of epigenetic mechanisms has been seen. This mainly based on the influence that epigenetic alterations have on an amazing number of biological processes, such as gene expression, imprinting, programmed DNA rearrangements, germ line silencing, developmentally cued stem cell division, and overall chromosomal stability and identity. It has become also evident that the constant exposure of living organisms to environment factors affects their genomes through epigenetic mechanisms. Viruses infecting animal cells are thought to play central roles in shaping the epigenetic scenario of infected cells. In this context it has become obvious that knowing the impact that viral infections have on the epigenetic control of their host cells will certainly lead to a better understanding of the interplay viruses have with animal cells. In fact, DNA viruses use host transcription factors as well as epigenetic regulators in such a way that they affect epigenetic control of gene expression that extends to host gene expression. At the same time, animal cells employ mechanisms controlling transcription factors and epigenetic processes, in order to eliminate viral infections. In summary, epigenetic mechanisms are involved in most virus-cell interactions. We now know that some viruses exhibit epigenetic immune evasion mechanisms to survive and propagate in their host; however, there is still much ambiguity over these epigenetic mechanisms of viral immune evasion, and most of the discovered mechanisms are still incomplete. Other animal viruses associated to cancer often deregulate cellular epigenetic mechanisms, silencing cellular tumor-suppressor genes and/or activating either viral or host cell oncogenes. In addition, in several cancers the down-regulation of tumor suppressor protein-coding genes and ncRNAs with growth inhibitory functions, such as miRNAs, have been closely linked to the presence of cell CpG island promoter hypermethylation. The goal of the aforementioned Research Topic is to bring together the key experimental and theoretical research, linking state-of-the-art knowledge about the epigenetic mechanisms involved in animal virus-cell interactions.

Download or read book Chromatin And Epigenetics An Introduction To Epigenetic Mechanisms written by Vincenzo Pirrotta and published by World Scientific. This book was released on 2023-07-05 with total page 525 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an introduction to epigenetics, a controversial term that denotes the mechanisms that instruct the genome on how to express the purely genetic information that encodes proteins. Starting with the discovery of repressor proteins in the 1960s, epigenetics evolved into a kind of user manual for the genetic information, telling the genome if, when, how much and in what cells to read genes. Advances in epigenetics in the past 15 years have revealed how it lies at the heart of virtually every branch of biological and medical sciences and an understanding of its basic principles is therefore essential for every student in this field.The field of chromatin and epigenetics has developed very rapidly in the past 15-20 years. The pace in the field of epigenetics has now slowed down, the basic outlines of the mechanisms and implications have solidified and a consensus has been achieved among the researchers in the field. At the same time, these mechanisms and implications are now an integral part of how we think about the genome. Genes are more than just DNA and more than just protein-coding sequences and this realization has revolutionized our understanding of the genome, gene expression and its regulation in development, health and disease. It is time, therefore, for a textbook to help train a new generation of biologists and health scientists as well as providing a basic competence among practitioners in allied fields. The present book has grown out of a course given for the past 13 years to advanced undergraduates at Rutgers University. In keeping with the experience in that course, the book is abundantly illustrated, presents a wealth of specific examples, and includes a chapter describing a number of methods and techniques that have driven the advances in the field.

Download or read book Epigenetic Epidemiology written by Karin B. Michels and published by Springer Science & Business Media. This book was released on 2012-01-03 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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!

Book excerpt: Epigenetics is the most exciting field in biology today, developing our understanding of how and why we inherit certain traits, develop diseases and age, and evolve as a species. This non-fiction comic book introduces us to genetics, cell biology and the fascinating science of epigenetics, which is rapidly filling in the gaps in our knowledge, allowing us to make huge advances in medicine. We'll look at what identical twins can teach us about the epigenetic effects of our environment and experiences, why certain genes are 'switched on' or off at various stages of embryonic development, and how scientists have reversed the specialization of cells to clone frogs from a single gut cell. In Introducing Epigenetics, Cath Ennis and Oliver Pugh pull apart the double helix, examining how the epigenetic building blocks and messengers that interpret and edit our genes help to make us, well, us.

Approaching this complex subject from a variety of perspectives, it presents a broad, historically grounded view that demonstrates the utility of this approach for understanding complex biological systems in development, disease, and evolution. Chapters cover such topics as morphogenesis and organ formation, conceptual foundations, and cell differentiation, and together demonstrate that the integration of epigenetics into mainstream developmental biology is essential for answering fundamental questions about how phenotypic traits are produced.
Download or read book Epigenetic Gene Expression and Regulation written by Suming Huang and published by Academic Press. This book was released on 2015-10-19 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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
