Diseases of the 21st century are complex with environmental and genetic causes. At the interface of these is Epigenetics - factors not specified by DNA sequence that control genes. Recent data show much of the risk associated with disease is set early in life, even during the time in the womb. The MCRI CDDE laboratory has assembled teams of researchers of diverse expertise investigating epigenetics of human development and complex disease to hopefully prevent or reverse them early in life.
Early Nutrition, Epigenetics And Developmental Outcomes In Children.

Summary
Increasing evidence demonstrates that early nutrition, including in pregnancy, has long lasting programming effects on later health of children. Evidence implicates epigenetics (literally ‘above DNA’) in mediating these effects. The most convincing data exists for obesity and related disorders such as metabolic syndrome, diabetes, and heart disease. The focus of this project is on understanding how ‘epigenetic’ mechanisms are influencing the way our genes function to cause these disorders.

Summary
The DNA in each of our cells does not exist alone, it is packaged into complex structures called chromosomes, through association with many different proteins. The distribution of these proteins varies along the length of a chromosome depending on the type of cell and this phenomenon is called 'epigenetics', literally meaning 'above the DNA'. Epigenetic analysis is the study of how proteins and other molecules can change the activity of a gene without changing the DNA sequence.

The distribution of these proteins varies along the length of a chromosome depending on the type of cell and this phenomenon is called 'epigenetics', literally meaning 'above the DNA'. Epigenetic analysis is the study of how proteins and other molecules can change the activity of a gene without changing the DNA sequence. All of our cells use epigenetic changes to help control how they grow and develop. Evidence suggests a direct link between diet and environmental influences on our epigenetic profile. Recent research has traced the origins of many of the health problems of adult life back to the earliest periods of development _ to the time spent in the womb and the first few years of life. If we are born with a low birth weight, we are more likely to get sick later in life. Overwhelming evidence exists that the environment in the womb is critical for a healthy birth weight (and health in later life) and it is thought that epigenetics may be the missing link between this environment, low birth weight, and therefore health in later life. In addition, mounting evidence supports a general link between epigenetic de-regulation and predisposition to disease. However, the timing and the overall contribution of environmental- genetic influences to the establishment of faulty epigenetic markings remain largely unknown. Twins are the best model to study this link as they share similar (but not identical environments) and some share identical genetic makeup. Using twins, Dr Jeffrey Craig and his team will investigate the factors in the prenatal environment that modify specific cells, leading to low birth weight and increase disease risk later in life. They predict that this occurs via specific changes in gene activity caused by epigenetic disruption.Read moreRead less
Defining Genetic And Epigenetic Variation During Early Development

Summary
We all began life with a set of genes inherited from our parents. However, it's now known that from the time we were in the womb onwards that genes can be turned off and on by the environment or even completely lost or gained. Even what your mother ate or how she behaved while she was pregnant could have influenced your future health. Because people are so different, we are studying the subtle differences between twins to tease out the factors that may influence our genes and our health.
Epigenetic Programming Of Immune Development In Utero: Role Of The Maternal Environment In The Allergy Epidemic

Funding Amount
$764,463.00
Summary
This study will provide new insights into the development of allergic disease. Specifically, we will explore the hypothesis that allergic disease and other disorders or immune dysregulation occur as a result of gene-environmental interactions in early life, and that these events begin in pregnancy when the developing fetus is still developing and most susceptible to these effects.

Schizophrenia is associated with great costs to the community and individual. Controlled studies have demonstrated Cognitive Behaviour Therapy (CBT) is efficacious in treating symptoms of schizophrenia. Studies of cognitive processes have also advanced understanding of psychotic phenomena. This initiative affords the opportunity to
1) Improve treatment efficacy by developing, testing and applying theoretically-driven models of psychotic symptoms.
2) Disseminate the findings of research on CBT for psychotic disorders in clinical settings by (a) training the work-force, and (b) facilitating CBT delivery in routine practice.
3) Apply CBT in various settings with a variety of psychotic populations to test its effectiveness in routine clinical settings.

Child health and developmental inequities: Evidence for precision policy. The project aims to use cutting edge analytic approaches applied to existing data to identify how policy interventions related to parents’ mental health, preschool programs, and the built environment can be optimised to reduce inequities in children’s mental, academic, and physical health outcomes. The project will be informed by our partners and advisers from across government portfolios and service delivery, ensuring tha ....Child health and developmental inequities: Evidence for precision policy. The project aims to use cutting edge analytic approaches applied to existing data to identify how policy interventions related to parents’ mental health, preschool programs, and the built environment can be optimised to reduce inequities in children’s mental, academic, and physical health outcomes. The project will be informed by our partners and advisers from across government portfolios and service delivery, ensuring that the evidence generated has contemporary policy relevance. The project expects to identify clear and actionable policy pathways to reduce child inequities in Australia, which can benefit decision makers by helping them to direct limited public funds towards intervention opportunities that will have the greatest impact.Read moreRead less

Ageing in China and Australia: Promoting health, productivity and wellbeing. This project aims to provide insights into the ways in which life-span development and social change in China have influenced the development of policies to support the health, productivity and wellbeing of people entering later life.

This project aims to provide insights into the ways in which life-span development and social change in China have influenced the development of policies to support the health, productivity and wellbeing of people entering later life. China’s population is rapidly ageing, bringing pressure on intergenerational support arising from smaller families, migration, urbanisation, and growing social inequalities. It may also bring opportunities. Using an understanding of social determinants, cultural context and policy responses, the project plans to undertake cross-national comparisons with Australia and examine historical influences and social variations within China. The project aims to deliver a better understanding of how public policy can enhance productivity, health and wellbeing of an ageing population.Read moreRead less
A disease of the brain: how do neurobiological explanations of addiction influence the attitudes and behaviour of smokers? This project explores the impact of promoting addiction as a "brain disease" on smokers' confidence in their ability to quit smoking, and the methods they use to quit. This is essential to inform public health policies designed to reduce the burden of tobacco related harms.
