Epigenetic regulation of gene expression
Social influences on gene expression and brain development.
Environmental conditions during early development shape brain development. The Meaney lab idenfitied phenotypic variations in rodent models that derive from variations in maternal care. Maternal care stably modifies the epigenetic state and expression of genes implicated in behavioural and endocrine responses to stress and learning. These studies were the first to describe the influence of the social environment on genomic structure and function.
The Meaney lab is currently pursuing several lines of research, including:
• The molecular mechanisms by which environmental signals alter epigenetic mechanisms and gene expression in rodent models using a range of genome-wide analyses, including next generation sequencing.
• The effects of gene x environment interactions on epigenetic mechanisms in humans using longitudinal cohort studies.
• Epigenetic programming as a mechanism for the transgenerational transmission of traits in human and rodent models.
• The influence of extreme forms for childhood experience, such as abuse/neglect, on epigentic signals and genome function in relation to vulnerability for affective disorders.

Michael J Meaney is a James McGill Professor of Medicine at Douglas Mental health University Institute of McGill University. He is the Director of the Maternal Adversity, Vulnerability and Neurodevelopment Project. Meaney also joined the Singapore Institute for Clinical Sciences in 2008 as a Senior Investigator and leads the Integrative Neuroscience Program. Meaney was educated at Loyola College of Montreal and received his PhD from Concordia University (Montreal) with post-doctoral training in Cell and Molecular Neurobiology at The Rockefeller University. Meaney’s primary research interest is that of the stable effects of early experience on gene expression and development, focusing on the influence of variations in maternal care. These studies have led to the discovery of novel epigenetic mechanisms for the influence of early experience. Meaney’s research is multidisciplinary and includes studies of behaviour and physiology, to molecular biology and genetics. He has authored over 375 journal articles. Graduates from Meaney’s lab holds faculty appointments across North America, Asia and Europe, including Columbia University, Queen’s University, University of California at Berkley, University of British Columbia, University of Michigan, University of Pennsylvania, the University of Toronto, INSERM (France) and the RIKEN Institute of Japan.
Margolese Brain Disorder Prize
This is the highest award for biomedical research, given by the Government of Quebec, which "goes to scientists whose research aims fall within the field of biomedicine. These fields include the medical sciences, the natural sciences, and engineering".
2014 Klaus J. Jacob Research Prize Laureate
The 2014 Klaus J. Jacob Research Prize Laureate has been awarded to Micheal Meany in recognition of his pioneering, cutting edge research on the biological mechanisms by which parental behaviour affects brain development and lifelong function. The Klaus J. Jacobs Awards is one of two international prizes presented to honour scientific achievements that are of exceptional social relevance in promoting the development of children and youth.The Jacobs Foundation attaches great importance to the practical application of scientific findings achieved through interdisciplinary research.
