Environmental factors can influence gene expression, impacting brain development and health outcomes, emphasizing early intervention and public health policy for child development.
Study finds environmental factors can influence gene expression without changing the DNA sequence.
Early-life experiences like stress become biologically embedded, affecting long-term health outcomes. It can influence genetic expression and brain development.
How Genes and Environment Shape Brain Health
In a comprehensive Genomic Press Interview, renowned neuroscientist Dr. Michael Meaney reveals pivotal discoveries about the intricate relationship between
“I have always been genuinely fascinated by the search for the developmental origins of individual differences in brain development and function,” says Dr. Meaney, whose work has earned him election to the American Academy of Arts and Sciences and the Order of Canada. “More broadly, and inspired by Hebb, I bore a profound dissatisfaction with the conceptually flawed distinction between the influences of ‘nature’ and ‘nurture’.”
His work at McGill University and later in Singapore with the GUSTO birth cohort study has given groundbreaking discoveries in epigenetics. “We too readily embrace narratives and technology that appeal to the general public, achieve headlines, and attract venture capital, but are far too simplistic to capture the complex reality of brain health truly,” Dr. Meaney observes, highlighting the need for nuanced understanding in neuroscience research.
Improving Child Development and Mental Health
The significance of Dr. Meaney’s work extends beyond the laboratory. His research has critical implications for public health policy, suggesting that early intervention programs could have lasting effects on brain development and mental health. The findings raise intriguing questions about how society might better support child development: How can we translate these scientific insights into practical interventions? What role do different types of early experiences play in shaping resilience?
With over 650 publications to his name, Dr. Meaney’s work continues to influence how we think about human development. His current focus on applying novel computational approaches to ‘big data’ opens new avenues for understanding gene-environment interactions. “The large data sets of the day are an ideal playground for one seeking to document gene x environment interactions on health and well-being,” he explains.
