Neural plasticity is a unique and adaptive feature of nervous system, which allows neurons to reorganize their interactions in response to a stimulation (intrinsic or extrinsic) to maintain their function. For these reasons, epigenetics emerges as a potential field for developing strategies to modulate changes in pathological situation because extrinsic factors and pharmacological tools can modify neural functioning in organisms during their life. Diet, exercise, environmental aspects, stressors or drugs are available to alter those mechanisms. Epigenetic involves certain molecular signaling pathways, as DNA methylation and histone acetylation and deacetylation, and the emerging non-coding small RNA, mainly microRNA, as a commanders of a number of translation processes. As most of molecular nervous cell alterations, epigenetic mechanisms play an important role in neural plasticity. This eBook collects the burgeoning advances in epigenetic mechanisms, focusing on new insights into cellular and molecular neurobiological mechanisms that underlie brain functioning in health and pathological conditions. Contributions go from basic cellular mechanism to therapeutic opportunities to tackle the challenges on nervous central system development and neurodegeneration.
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.
Recent studies have indicated that epigenetic processes may play a major role in both cellular and organismal aging. These epigenetic processes include not only DNA methylation and histone modifications, but also extend to many other epigenetic mediators such as the polycomb group proteins, chromosomal position effects, and noncoding RNA. The topics of this book range from fundamental changes in DNA methylation in aging to the most recent research on intervention into epigenetic modifications to modulate the aging process. The major topics of epigenetics and aging covered in this book are: 1) DNA methylation and histone modifications in aging; 2) Other epigenetic processes and aging; 3) Impact of epigenetics on aging; 4) Epigenetics of age-related diseases; 5) Epigenetic interventions and aging: and 6) Future directions in epigenetic aging research. The most studied of epigenetic processes, DNA methylation, has been associated with cellular aging and aging of organisms for many years. It is now apparent that both global and gene-specific alterations occur not only in DNA methylation during aging, but also in several histone alterations. Many epigenetic alterations can have an impact on aging processes such as stem cell aging, control of telomerase, modifications of telomeres, and epigenetic drift can impact the aging process as evident in the recent studies of aging monozygotic twins. Numerous age-related diseases are affected by epigenetic mechanisms. For example, recent studies have shown that DNA methylation is altered in Alzheimer’s disease and autoimmunity. Other prevalent diseases that have been associated with age-related epigenetic changes include cancer and diabetes. Paternal age and epigenetic changes appear to have an effect on schizophrenia and epigenetic silencing has been associated with several of the progeroid syndromes of premature aging. Moreover, the impact of dietary or drug intervention into epigenetic processes as they affect normal aging or age-related diseases is becoming increasingly feasible.
DNA Modifications in the Brain: Neuroepigenetic Regulation of Gene Expression begins with an historical overview of the early discoveries surrounding DNA methylation in the mammalian brain and then explores the evidence supporting a role for this epigenetic mechanism in controlling gene expression programs across the lifespan in both normal and diseased states. Chapters describe new directions and technological advances, and provide an overview of what the future holds for this exciting new field. This book is ideal for medical, graduate and advanced undergraduate students, but is also a great resource for researchers who need a broad introduction to the dynamic nature of DNA that sheds light on evolving concepts of gene-environment interaction and their effects on adaptation and neuropsychiatric disease. Provides a comprehensive overview of the many facets of DNA modifications Discusses the impact of this dynamic epigenetic mechanism across brain development and lifespan at behavioral, cognitive, molecular and genetic levels Contains contributions by influential leaders in the field Edited by a Neuroscientist to further promote synthesis between epigenetics, neuroscience, and clinical relevance
Epigenetics in Psychiatry covers all major areas of psychiatry in which extensive epigenetic research has been performed, fully encompassing a diverse and maturing field, including drug addiction, bipolar disorder, epidemiology, cognitive disorders, and the uses of putative epigenetic-based psychotropic drugs. Uniquely, each chapter correlates epigenetics with relevant advances across genomics, transcriptomics, and proteomics. The book acts as a catalyst for further research in this potentially very important and useful area of psychiatry. The elucidation of basic principles of epigenetic biology points to the creation of more optimal and effective therapies for major classes of psychiatric disease. In this regard, epigenetic therapy, the use of drugs to correct epigenetic defects, may help in the pharmacotherapy of patients with these disorders. With time, such advances may eventually point to replacements for psychotropic drugs presently of symptomatic value and low efficacy. Moreover, there is evidence to suggest that other forms of treatment commonly used in the management of psychiatric disorders, like psychotherapy and electroconvulsive therapy, may also act by epigenetic mechanisms. Chapters review fascinating new areas of research across neuronal stem cells, cognitive disorders, and transgenerational epigenetics through drug addiction Relates broad advances in psychiatric epigenetics to a modern understanding of the genome, transcriptome, and protein Catalyzes knowledge discovery in both basic epigenetic biology and clinical application as epigenetic targets for drug discovery
Neuropsychiatric Disorders and Epigenetics is a comprehensive reference for the epigenetic basis of most common neuropsychiatric disorders. The volume is organized into chapters representing individual neuropsychiatric disorders, from addition to obesity contributed by leading experts in their respective fields. The epigenetic aspects of each disorder are discussed, in the context of the full range of epigenetic mechanisms including DNA modification, histone post-translational modification, chromatin organization and non-coding RNA. A particular emphasis is placed on potential epigenetic interventions, when the effects of environmental stimuli on epigenetic states is particularly relevant o disease. Recent discoveries in epigenetic research enabled by epic advances in genomic technologies have positioned the field for broad translation to therapeutic interventions for previously unmanageable disorders Neuropsychiatric disorders represent a prime target of epigenetic interventions as they are highly debilitating, often chronic diseases with enormous costs to society. Thus, this volume will help define epigenetics as a key player in neuropsychiatric disorders, highlighting the full spectrum of epigenetic mechanisms underlying such disorders and introducing the vast range of epigenetic therapies under development. Analyzes the effects of environmental stimuli on epigenetic states that correlate with neuropsychiatric disease induction Reviews the epigenetic basis for common neuropsychiatric disorders, thereby guiding translational therapies for clinicians and mechanistic studies for scientists Extensive use of diagrams, illustrations, tables, and graphical abstracts for each section providing rapid assessment

The Handbook of Behavioral Genetics and Phenotyping represents an integrative approach to neurobehavioural genetics; worldwide experts in their field will review all chapters. Advanced overviews of neurobehavioural characteristics will add immense value to the investigation of animal mutants and provide unique information about the genetics and behavioural understanding of animal models, under both normal and pathological conditions. Cross-species comparisons of neurobehavioural phenotypes will pave the way for an evolutionary understanding of behaviour. Moreover, while biological sciences are progressing towards a holistic approach to investigate the complexity of organisms (i.e., “systems biology” approach), an integrated analysis of behavioural phenotyping is still lacking. The Handbook of Behavioral Genetics and Phenotyping strengthens the cross-talk within disciplines that investigate the fundamental basis of behaviour and genetics. This will be the first volume in which traditionally distant fields including genomics, behaviour, electrophysiology, neuroeconomics, and computational neuroscience, among others, are evaluated together and simultaneously accounted for during discussions of future perspectives.

The ‘epi-(Greek for ‘over’, ‘above’)genome’, with its rich cache of highly regulated, structural modifications—including DNA methylation, histone modifications and histone variants—defines the moldings and three-dimensional structures of the genomic material inside the cell nucleus and serves, literally, as a molecular bridge linking the environment to the genetic materials in our brain cells. Due to technological and scientific advances in the field, the field of neuroepigenetics is currently one of the hottest topics in the basic and clinical neurosciences. The volume captures some of this vibrant and exciting new research, and conveys to the reader an up-to-date discussion on the role of epigenetics across the lifespan of the human brain in health and disease. Topics cover the entire lifespan of the brain, from transgenerational epigenetics to neurodevelopmental disease to disorders of the aging brain. All chapters are written with dual intent, to provide the reader with a timely update on the field, and a discussion of provocative or controversial findings in the field with the potential of great impact for future developments in the field.
Epigenetic mechanisms (DNA modifications, histone alterations and non-coding RNAs) are crucial for transcriptional regulation and alterations of the “physiological epigenome” are increasingly associated with human diseases. During the last decade the emerging field of neuroepigenomics have started to impact tremendously in areas such learning and memory, addiction or neurodegeneration. This expert volume covers the role of epigenetic molecular mechanism in regulation of central nervous system’s function, one of the most exciting areas of contemporary molecular neuroscience. The book describes the current knowledge on the epigenetic basis of human disease covering the complete lifespan: from neurodevelopment/childhood (Rett Syndrome, Rubinstein-Taybi, autism), adolescence (eating disorders, drug addiction, anxiety), adulthood (depression, schizophrenia, amyotrophic lateral sclerosis, Huntington’s disease) and elderly (Alzheimer’s disease, Parkinson’s disease). The book also covers the three major players on neuroepigenomic mechanisms: histones alterations, DNA modifications and non-coding RNAs, their roles at the molecular and cellular level and the impact of their alterations on neuronal function and behavior. Finally, a special chapter on state-of-the-art technologies helps the reader not only to understand epigenetic driven changes in human cognition and diseases but also the methodology that will help to generate paradigm shifts on our understanding of brain function and the role of the neuroepigenome in human diseases.
