Annual Research Review: DNA methylation as a mediator in the association between risk exposure and child and adolescent psychopathology / Edward D. BARKER in Journal of Child Psychology and Psychiatry, 59-4 (April 2018)
[article]
Titre : Annual Research Review: DNA methylation as a mediator in the association between risk exposure and child and adolescent psychopathology Type de document : Texte imprimé et/ou numérique Auteurs : Edward D. BARKER, Auteur ; E. WALTON, Auteur ; Charlotte A. M. CECIL, Auteur Article en page(s) : p.303-322 Langues : Anglais (eng) Mots-clés : DNA methylation adolescence childhood developmental psychopathology environmental risk epigenetics externalising problems internalising problems Index. décimale : PER Périodiques Résumé : BACKGROUND: DNA methylation (DNAm) is a potential mechanism for propagating the effects of environmental exposures on child and adolescent mental health. In recent years, this field has experienced steady growth. METHODS: We provide a strategic review of the current child and adolescent literature to evaluate evidence for a mediating role of DNAm in the link between environmental risks and psychopathological outcomes, with a focus on internalising and externalising difficulties. RESULTS: Based on the studies presented, we conclude that there is preliminary evidence to support that (a) environmental factors, such as diet, neurotoxic exposures and stress, influence offspring DNAm, and that (b) variability in DNAm, in turn, is associated with child and adolescent psychopathology. Overall, very few studies have examined DNAm in relation to both exposures and outcomes, and almost all analyses have been correlational in nature. CONCLUSIONS: DNAm holds potential as a biomarker indexing both environmental risk exposure and vulnerability for child psychopathology. However, the extent to which it may represent a causal mediator is not clear. In future, collection of prospective risk exposure, DNAm and outcomes - as well as functional characterisation of epigenetic findings - will assist in determining the role of DNAm in the link between risk exposure and psychopathology.
