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. All of our cells ....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. 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.
Estimating And Alleviating The Impacts Of Age-Related Sensory Decline

Summary
Sensory loss and dementia disproportionately affect older adults, often co-occur, and are the two leading contributors to disability burden among older Australians. This research will investigate the consequences that hearing and vision loss have for older adult health and wellbeing, informing strategies to reduce the disability burden of age-related sensory loss. These impacts include cognitive decline and dementia, mental health, quality of life, disability and independent living.
Using Health Outcome Data From Pooled Longitudinal Studies Of Ageing To Develop Statistical And Microsimulation Models T

Summary
This project draws together data from nine Australian Longitudinal Studies of Ageing (LSAs), including 53484 participants, that will be used to identify factors capable of preventing disease, reducing ill-health, and promoting engaged and successful ageing for Australians. The focus is upon conditions that significantly contribute to the burden of disease including cognitive decline and dementia, sensory impairment, impairment in mobility and common mental disorders such as depression.

The focus is upon conditions that significantly contribute to the burden of disease including cognitive decline and dementia, sensory impairment, impairment in mobility and common mental disorders such as depression. Although individual studies contain rich data on particular topics, there is only a small number of individuals in each study with specific medical conditions, or combinations of different conditions, especially at the older ages. Pooling data from nine studies will overcome this problem. This innovative and interdisciplinary study also involves development of the first Australian dynamic micro-simulation model of the health and social outcomes of the baby boomer and older cohorts. The simulation will allow for evaluation of the impact of modifying risk factors, and costs associated with different trajectories of health and ageing. Our program takes an interdisciplinary life course approach, incorporating interdependencies among demographic, behavioural, social, economic and health factors. Our multidisciplinary team and collaborative pooling of existing studies adds value and builds upon experience, as recommended in the Prime Minister's Science, Engineering and Innovation Council 2003 report. The outcomes will direct health and social policy to promote health behaviour, and social and medical interventions to compress morbidity and optimize healthy ageing in Australian society over the next 40 years.Read moreRead less
TELEPHONE COUNSELLING FOR MAINTENANCE OF PHYSICAL ACTIVITY, WEIGHT LOSS And GLYCAEMIC CONTROL IN TYPE 2 DIABETES

Funding Amount

Summary
Regular exercise, a healthy diet and weight loss are key to managing type 2 diabetes, yet these are major challenges for most people with diabetes. This study will evaluate the impact of a telephone counselling program to assist people with type 2 diabetes to exercise, eat a healthy diet and lose weight, with the goal of helping them to sustain these changes over the long-term. It is expected that these lifestyle changes will also result in improved blood glucose control and quality of life.
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.
