Book Description
Epigenetics of Stress and Stress Disorders, a new volume in the Translational Epigenetics series, examines the epigenetic mechanisms involved in modifying DNA following prolonged stress or trauma. This is accomplished through the evaluation of both the physiological and molecular effects of stress on the body that can eventually lead to stress disorders. The book begins by providing a psychiatric, biological, and phenomenological foundation for understanding stress disorders, before delving into the genomics of stress disorders. From here, chapter authors discuss a range of recent epigenetic research in the area, highlighting epigenome-wide association studies (EWAS), exciting developments in noncoding RNA studies, possible effects of prolonged stress on telomere shortening, and the long-term physical effects of PTSD on the health of patients. The book also examines the effect of adversity during sensitive periods or development and across the life span. The book concludes by looking at possible transgenerational stress-induced epigenetic alterations on future offspring and important areas of research for public health, along with the potential for epigenetic therapeutics or "epidrugs. - Examines the epigenetics of stress, trauma, and related stress disorders - Connects new research to clinical practice and highlights implications for patient care, drug discovery, and public health - Discusses the epigenetic effect of adversity across the life span, and transgenerational stress-induced epigenetic alterations - Features chapter contributions from international experts in the field

Publisher: Frontiers Media SA
ISBN: 2889194582
Category : Epigenetics
Languages : en
Pages : 159

Book Description
This research topic focuses on epigenetic components of PTSD. Epigenetic mechanisms are a class of molecular mechanisms by which environmental influences, including stress, can interact with the genome to have long-term consequences for brain plasticity and behavior. Articles herein include empirical reports and reviews that link stress and trauma with epigenetic alterations in humans and animal models of early- or later-life stress. Themes present throughout the collection include: DNA methylation is a useful biomarker of stress and treatment outcome in humans; epigenetic programming of stress-sensitive physiological systems early in development confers an enhanced risk on disease development upon re-exposure to trauma or stress; and, long-lived fear memories are associated with epigenetic alterations in fear memory and extinction brain circuitry.

Category : Science
Languages : en
Pages : 684

Book Description
Handbook of Epigenetics: The New Molecular and Medical Genetics, Second Edition, provides a comprehensive analysis of epigenetics, from basic biology, to clinical application. Epigenetics is considered by many to be the new genetics in that many biological phenomena are controlled, not through gene mutations, but rather through reversible and heritable epigenetic processes. These epigenetic processes range from DNA methylation to prions. The biological processes impacted by epigenetics are vast and encompass effects in lower organisms and humans that include tissue and organ regeneration, X-chromosome inactivation, stem cell differentiation, genomic imprinting, and aging. The first edition of this important work received excellent reviews; the second edition continues its comprehensive coverage adding more current research and new topics based on customer and reader reviews, including new discoveries, approved therapeutics, and clinical trials. From molecular mechanisms and epigenetic technology, to discoveries in human disease and clinical epigenetics, the nature and applications of the science is presented for those with interests ranging from the fundamental basis of epigenetics, to therapeutic interventions for epigenetic-based disorders. - Timely and comprehensive collection of fully up-to-date reviews on epigenetics that are organized into one volume and written by leading figures in the field - Covers the latest advances in many different areas of epigenetics, ranging from basic aspects, to technologies, to clinical medicine - Written at a verbal and technical level that can be understood by scientists and college students - Updated to include new epigenetic discoveries, newly approved therapeutics, and clinical trials

The Neurobiological Basis of Suicide

The Neurobiological Basis of Suicide PDF Author: Yogesh Dwivedi
Publisher: CRC Press
ISBN: 143983881X
Category : Medical
Languages : en
Pages : 485

Book Description
With recent studies using genetic, epigenetic, and other molecular and neurochemical approaches, a new era has begun in understanding pathophysiology of suicide. Emerging evidence suggests that neurobiological factors are not only critical in providing potential risk factors but also provide a promising approach to develop more effective treatment and prevention strategies. The Neurobiological Basis of Suicide discusses the most recent findings in suicide neurobiology. Psychological, psychosocial, and cultural factors are important in determining the risk factors for suicide; however, they offer weak prediction and can be of little clinical use. Interestingly, cognitive characteristics are different among depressed suicidal and depressed nonsuicidal subjects, and could be involved in the development of suicidal behavior. The characterization of the neurobiological basis of suicide is in delineating the risk factors associated with suicide. The Neurobiological Basis of Suicide focuses on how and why these neurobiological factors are crucial in the pathogenic mechanisms of suicidal behavior and how these findings can be transformed into potential therapeutic applications.

The DNA, RNA, and Histone Methylomes

The DNA, RNA, and Histone Methylomes PDF Author: Stefan Jurga
Publisher: Springer Nature
ISBN: 3030147924
Category : Medical
Languages : en
Pages : 624

Book Description
This book reviews the chemical, regulatory, and physiological mechanisms of protein arginine and lysine methyltransferases, as well as nucleic acid methylations and methylating enzymes. Protein and nucleic acid methylation play key and diverse roles in cellular signalling and regulating macromolecular cell functions. Protein arginine and lysine methyltransferases are the predominant enzymes that catalyse S-adenosylmethionine (SAM)-dependent methylation of protein substrates. These enzymes catalyse a nucleophilic substitution of a methyl group to an arginine or lysine side chain nitrogen (N) atom. Cells also have additional protein methyltransferases, which target other amino acids in peptidyl side chains or N-termini and C-termini, such as glutamate, glutamine, and histidine. All these protein methyltransferases use a similar mechanism. In contrast, nucleic acids (DNA and RNA) are substrates for methylating enzymes, which employ various chemical mechanisms to methylate nucleosides at nitrogen (N), oxygen (O), and carbon (C) atoms. This book illustrates how, thanks to there ability to expand their repertoire of functions to the modified substrates, protein and nucleic acid methylation processes play a key role in cells.

Stress and Poverty

Stress and Poverty PDF Author: Michael Breitenbach
Publisher: Springer Nature
ISBN: 3030777383
Category : Science
Languages : en
Pages : 249

Book Description
The word stress is everywhere and highly overused. Everyone is stressed, it seems, all the time. Looking into the meaning of stress in the natural science and the humanities, this book explores cellular stress as cause of and in correlation with what humans experience as stress. When do we psychologically feel stress and when do we show physiological evidence of stress in our brain? Stress is a deviation from what feels normal and healthy. It can be created by social or economic factors and become chronic, which has substantial impacts on the individual and society as a whole. Focusing on poverty as one chronic inducer of stress, this book explores how the lack of pressure-free time, the hardships and unpredictability of everyday life and a general lack of protection lead to destructive toxic stress. This pressure affects cognitive and social functioning, brain development during childhood and may also result in premature aging. How can the sciences inform our understanding of and our response to stress? What can be done about toxic stress both on a personal level and in terms of structures and policies? The book is written for anyone interested in stress, its causes and consequences, and its relationship to poverty.
