CHAMPAGNE, Auteur Article en page(s) : p.1219-1228 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : The quality of the environment experienced by an individual across his or her lifespan can result in a unique developmental trajectory with consequences for adult phenotype and reproductive success. However, it is also evident that these experiences can impact the development of offspring with continued effect on subsequent generations. Epigenetic mechanisms have been proposed as a mediator of both these within- and across-generation effects, and there is increasing evidence to support the role of environmentally induced changes in DNA methylation, posttranslational histone modifications, and noncoding RNAs in predicting these outcomes. Advances in our understanding of these molecular modifications contribute to increasingly nuanced perspectives on plasticity and transmission of phenotypes across generations. A challenge that emerges from this research is in how we integrate these “new” perspectives with traditional views of development, reproduction, and inheritance. This paper will highlight evidence suggestive of an epigenetic impact of the environment on mothers, fathers, and their offspring, and illustrate the importance of considering the dynamic nature of reproduction and development and inclusive views of inheritance within the evolving field of behavioral and environmental epigenetics.

Linking prenatal maternal adversity to developmental outcomes in infants: The role of epigenetic pathways / Catherine MONK in Development and Psychopathology, 24-4 (November 2012)  

Public ISBD [article]  inDevelopment and Psychopathology > 24-4 (November 2012) . - p.1361-1376 Titre : Linking prenatal maternal adversity to developmental outcomes in infants: The role of epigenetic pathways Type de document : Texte imprimé et/ou numérique Auteurs : Catherine MONK, Auteur ; Julie A. SPICER, Auteur ; Frances A. CHAMPAGNE, Auteur Année de publication : 2012 Article en page(s) : p.1361-1376 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Prenatal exposure to maternal stress, anxiety, and depression can have lasting effects on infant development with risk of psychopathology. Although the impact of prenatal maternal distress has been well documented, the potential mechanisms through which maternal psychosocial variables shape development have yet to be fully elucidated. Advances in molecular biology have highlighted the role of epigenetic mechanisms in regulating gene activity, neurobiology, and behavior and the potential role of environmentally induced epigenetic variation in linking early life exposures to long-term biobehavioral outcomes. In this article, we discuss evidence illustrating the association between maternal prenatal distress and both fetal and infant developmental trajectories and the potential role of epigenetic mechanisms in mediating these effects. Postnatal experiences may have a critical moderating influence on prenatal effects, and we review findings illustrating prenatal–postnatal interplay and the developmental and epigenetic consequences of postnatal mother–infant interactions. The in utero environment is regulated by placental function and there is emerging evidence that the placenta is highly susceptible to maternal distress and a target of epigenetic dysregulation. Integrating studies of prenatal exposures, placental function, and postnatal maternal care with the exploration of epigenetic mechanisms may provide novel insights into the pathophysiology induced by maternal distress.
