Stress and Epigenetics in Suicidediscusses the central role of epigenetic modifications in suicidal behavior. As early-life stress and an individual's ability to cope with such stressors, combined with psychological factors, social factors, and existential and cognitive factors can predispose young people to suicidal behavior and put them at added risk of suicidal behavior later in life, this book provides readers with an overview of the neurobiology of stress, an introduction to the epigenetic changes induced by stress, and an understanding of how vulnerability and resilience to stress are built. It integrates these mechanisms into a biobehavioral model of suicide based on epigenetic marks, gene-environment interactions, and other stressors. More importantly, it provides future direction for research and discusses potential interventions. This book is an ideal and trusted resource for researchers and clinicians who are interested in learning how the environment can affect behavior through genetics, and for those seeking the development of new methods for suicide prevention. Explores the neurobiology of stress and stress-related epigenetics, including discussion of the role of stress-induced epigenetic changes in behavioral, emotional, and cognitive mechanisms and whether these epigenetic marks are transgenerational Provides compelling biobehavioral models of suicide based on genetics, epigenetics, and behavioral adjustment Integrates social, psychological, and existential influences, giving readers a better understanding of the interdisciplinary nature of suicide risk factors Presents future directions for suicide-prevention strategies that incorporate recent research on genomics and stress resilience

The genomes of both plants and animals are under constant stress ranging from jumping genetic elements to UV irradiation. A fundamental question in the field of epigenetics is how chromatin landscapes are altered to generate adaptive responses. Epigenetic modifications allow heritable changes in the expression of a gene, without mutation of the underlying DNA sequences. My first project identified a novel epigenetic mechanism of regulating plant development involving a histone H3 mutation. Specifically, we found that a lysine-to-methionine mutation at the 36th amino acid of histone H3 (H3K36M) had a dominant negative affect on genome-wide H3K36 methylation leading to the misregulation of critical genes in the flowering and shoot branching pathways. These gene expression changes likely lead to the pleiotropic developmental defects that accompanied this mutation. Due to their sessile nature, plants are highly adaptive to the ever-changing environment. DNA methylation may contribute to adaptivity given its roles in gene expression and its heritability through meiotic generations in plants. My second project investigated the genetic, epigenetic, and physiological characteristics of a high altitude Tibetan accession of A. thaliana (Lhasa-0). Interestingly, Lhasa-0 is tolerant to multiple environmental stressors. This accession also had an uncommon frameshift mutation in the C-terminal of the chromomethylase-2 (CMT2) gene. This mutation was found to be responsible for a genome-wide reduction in CHH context DNA methylation (where H = A, T or C). Consistent with Lhasa-0's environmental tolerance, we found cmt2 mutants (Col-0 ecotype) were also tolerant to multiple stressors (UV-B, heat, and pathogen). These results suggest DNA methylation plays a role in tolerance to a broad range of stressors and inactivating CMT2 mutations may be adaptive for wild accessions. Relatedly, my third project aimed to screen DNA methylation mutants for basal thermotolerance. We found two genotypes with opposing effects on DNA methylation and thermotolerance. To elucidate the underlying molecular mechanisms, we performed time course transcriptome analysis and found that heat stress pathways are extremely robust and changes in DNA methylation do not drastically alter the heat stress transcriptome. We also performed time-course tandem mass spectrometry uncovering both heat-dependent and -independent genome-wide changes in histone modifications. Collectively, these projects shed new light on how chromatin and epigenetic modifications affect plant development and stress tolerance.

Dogs, Canis familiaris, share the lives of humans all over the world. That dogs, and the behavior of dogs, are of interest to many is therefore no surprise. In this thesis, the main aim has been to identify factors that affect dogs’ behaviours. The dog, Canis familiaris, is our first domesticated animal. Since domestication, various types of dogs have developed through adaptation to an environment shared with humans and through our selective breeding, resulting in a unique variation in morphology and behaviour. Although there is an individual variation in the behaviour of dogs, there is also a difference between breeds. Moreover, selection during the last decades has split some breeds into divergent types. Labrador and golden retrievers are divided into a common type, for show and companionship, and a field type, for hunting. By comparing the breed types, we can study the effects of recent selection. In Paper I, we investigate differences in general behavioural traits between Labrador and golden retriever and between common and field type within the two breeds by using results from the standardized behaviour test Dog Mentality Assessment. There were differences between breeds and types for all behavioural traits. However, there was also an interaction between breed and type. Thus, a common/field-type Labrador does not behave like a common/field-type golden retriever. Even though they have been selected for similar traits, the selection has affected the general behavioural traits differently in the two breeds. In paper II, we were interested in dogs’ human-directed social skills. Dogs have a high social competence when it comes to humans. Two experiments commonly used to study these skills are the problem-solving test, where dogs’ human-directed behaviours when faced with a problem are measured, and the pointing test, where dogs are tested on how well they understand human gestures. We compared the social skills of German shepherds and Labrador retrievers, and of common- and field-type Labradors. Labradors were more successful in the pointing test and German shepherds stayed closer to their owners during the problem solving. Among Labrador types, the field type had more human eye contact than the common type. Importantly, when comparing the two experiments, we found no positive correlations between the problem-solving test and the pointing test, suggesting that the two tests measure different aspects of human-directed social behaviour in dogs. A previous study has identified two suggestive genetic regions for human-directed social behaviours during the problem-solving test in beagles. In paper III, we show that these SNPs are also associated to social behaviours in Labrador and golden retrievers. Moreover, the Labrador breed types differed significantly in allele frequencies. This indicates that the two SNPs have been affected by recent selection and may have a part in the differences in sociability between common and field type. The behaviour of dogs cannot simply be explained by genetics, there is also an environmental component. In paper IV, we study which factors that affect long-term stress in dogs. Long-term cortisol can be measured by hair samples. We found a clear synchronization in hair cortisol concentrations between dogs and their owners. Neither dogs’ activity levels nor their behavioural traits affected the cortisol, however, the personality of the owners did. Therefore, we suggest that dogs mirror the stress level of their owners. The mediator between genes and the environment is epigenetics, and one epigenetic factor is DNA methylation. In paper V, we compared methylation patterns of wolves and dogs as well as dog breeds. Between both wolves and dogs and among dogs there were substantial differences in methylated DNA regions, suggesting that DNA methylation is likely to contribute to the vast variation among canines. We hypothesize that epigenetic factors have been important during domestication and in breed formation. In this thesis, I cover several aspects on how dogs’ behaviours can be affected, and paint an intricate picture on how genetics, epigenetics, and human-dog relations forms dog behaviour.

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

Why do we grow up to look, act, and feel as we do? Through most of the twentieth century, scientists and laypeople answered this question by referring to two factors alone: our experiences and our genes. But recent discoveries about how genes work have revealed a new way to understand the developmental origins of our characteristics. These discoveries have emerged from the new science of behavioral epigenetics--and just as the whole world has now heard of DNA, "epigenetics" will be a household word in the near future. Behavioral epigenetics is important because it explains how our experiences get under our skin and influence the activity of our genes. Because of breakthroughs in this field, we now know that the genes we're born with don't determine if we'll end up easily stressed, likely to fall ill with cancer, or possessed of a powerful intellect. Instead, what matters is what our genes do. And because research in behavioral epigenetics has shown that our experiences influence how our genes function, this work has changed how scientists think about nature, nurture, and human development. Diets, environmental toxins, parenting styles, and other environmental factors all influence genetic activity through epigenetic mechanisms; this discovery has the potential to alter how doctors treat diseases, and to change how mental health professionals treat conditions from schizophrenia to post-traumatic stress disorder. These advances could also force a reworking of the theory of evolution that dominated twentieth-century biology, and even change how we think about human nature itself. In spite of the importance of this research, behavioral epigenetics is still relatively unknown to non-biologists. The Developing Genome is an introduction to this exciting new discipline; it will allow readers without a background in biology to learn about this work and its revolutionary implications.

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.

This is the first comprehensive, authoritative, and easy-to-understand introduction to modern epigenetics. Authored by two active researchers in the field, it introduces key concepts one step at a time, enabling students at all levels to benefit from it. The authors begin by presenting a historical overview that places epigenetics in context, and makes it clear that the field is not (as some presume) completely new. Next, they introduce and explain key epigenetic mechanisms, and discuss the roles these mechanisms may play in inheritance, organism development, health and disease, behavior, evolution, ecology, and the interaction of individual organisms with their environments. Coverage includes: non-coding RNAs in each kingdom; allelic interactions; CRYSPR; gene silencing; epigenetics of germline and epigenetic memory; epigenetic regulation of genome stability and plant stress response; and much more. The authors conclude by offering significant new insights into how knowledge of epigenetics and epigenomics may promote the development of technologies and solutions in areas ranging from behavioral neuroscience to cancer treatment, toxicology to the development of hardier crops.

Every species has to preserve the integrity of its genome to ensure faithful passage of genetic information to the progeny. At the same time, there are times during the life of the organism and population in general when a fine balance in genome stability and diversification has to be made to benefit the survival of the species. Genome Stability teaches the reader how various species maintain this fine balance in genome stability and genome diversification in response to their environments. Genome Stability covers a wide range of topics, including the genome stability of DNA/RNA viruses, prokaryotes, single cell eukaryotes, lower multicellular eukaryotes and mammals. Topics also include major DNA repair mechanisms, the role of chromatin in genome stability, human diseases associated with genome instability as well as changes in genome stability in response to aging. Finally, Genome Stability covers how epigenetic factors contribute to genome stability and how the species pass the memory of the encounters to the progeny, thus influencing the genome of the progeny in an indirect manner. This volume is an essential resource for geneticists, epigeneticists, and molecular biologists who are looking to gain a deeper understanding of this rapidly-expanding field, and can also be of great use to advanced students who are looking to gain additional expertise in genome stability. Includes a collection of chapters on genome stability research from various kingdoms, including topics such as epigenetics and transgenerational effects Provides the first comprehensive coverage of the differences in the mechanisms utilized by different organisms to maintain genomic stability Contains applications of genome instability and its effect on human diseases Explains how various species maintain the fine balance in genome stability and genome diversification in response to their environments
