The importance of DNA methylation in response to environmental changes (ARC Discovery Project administered by the University of New South Wales) (2015–2018)

Abstract:
This project aims to investigate the importance of DNA methylation, a process whereby gene expression can be altered without changes in the DNA code, in regulating our responses to environmental challenges. This project investigates this using well validated models of adult exposure to high fat diet or psychological stress in mice and tissue-specific (liver and brain) deletion of the major methylation enzymes. It will compare functional, gene expression and methylation status after such challenges in intact and methylase deleted animals to determine how vital this process really is. This work has major implications for our understanding of epigenetics, and the ways in which genes interact with the environment especially in times of change.
