Summary
The poor understanding of the cause of asthma has made prevention strategies unsuccessful. This study will provide valuable data for understanding the interactions between exposure to environmental stimuli and LPS pathway genes on the development of allergy and asthma in infants. As environmental modifications and dietary interventions during pregnancy are being investigated, the findings from the proposed study will be important in guiding prevention practices of allergic diseases.

Summary
How we handle chemicals that enter our bodies depends on a series of enzymes that are responsible for breaking down the chemicals and eliminating them. The activity of many of these enzymes varies between individuals so our responses to chemicals and drugs is different for each individual. Some of the enzymes vary because of inherited mutations, but others vary because of the diets we eat and the environment in which we live. This project will investigate a major enzyme called acetlytransferase ....How we handle chemicals that enter our bodies depends on a series of enzymes that are responsible for breaking down the chemicals and eliminating them. The activity of many of these enzymes varies between individuals so our responses to chemicals and drugs is different for each individual. Some of the enzymes vary because of inherited mutations, but others vary because of the diets we eat and the environment in which we live. This project will investigate a major enzyme called acetlytransferase that has been implicated as a risk factor in diseases such as cancer, asthma, liver cirrhossis and adverse drug reactions. We plan to look at the enzyme in cells and determine what environmental factors contribute to its variation between individuals, and how this impacts on the genetic mutations that have been found in its gene. From these studies, we will have a much better undersanding of how different people metabolise foreign chemicals, and should be able to predict those most at risk of certain diseases.Read moreRead less

Summary
Atopic dermatitis, or eczema, is an increasingly common severe allergic condition affecting the skin that afflicts up to 30% of all Australian children. Eczema has significant financial impact on families as well on the health and well being of the affected child. The majority of asthmatics are also allergic, explaining why many children who suffer from eczema often go on to develop asthma as well.

Eczema has significant financial impact on families as well on the health and well being of the affected child. The majority of asthmatics are also allergic, explaining why many children who suffer from eczema often go on to develop asthma as well. A familial history of asthma or eczema is an important risk factors for a child developing the disorder, meaning that allergy is to a large extent determined by the genes we inherit from our parents. Our genes consist of four different building blocks, called nucleotides, which are identified by four letters: A, G, C and T. Each gene has a specific spelling of these four letters, although between any two people there will invariably be small single letter differences in the way a gene is spelt. Normally, these differences have no effect. In an allergic individual, however, these differences do have an effect. Identifying differences in the way a gene is spelt and why this should lead to eczema or asthma is a major research goal. In the past several years a number of genes have been identified that play an important role in allergy and we have recently identified a spelling difference in a new gene that we believe is important in the allergic response of eczema and asthma. At the moment, we can only guess how this gene might work. We know it is expressed in cells of our immune system that are important in allergy. We also suspect it might be an on or off switch for other genes important for allergy. This project will test these ideas and show how differences in the way this gene is spelt lead to differences in how this gene works. This will be important in adding another piece to the puzzle of how genes control allergy and could lead to better and earlier treatment of these disorders with improved health for affected children as well as adults.Read moreRead less

Current known risk factors explain approximately half of all cardiovascular diseases. The search for new risk factors is therefore a high priority. Evidence suggests that chronic inflammation is closely involved in the process of atherosclerosis and its clinical complications. This study aims to determine if sensitive serum markers of inflammation and gene-environment interactions that affect inflammation will predict the extent and progression of carotid atherosclerosis in an Aboriginal and a non Aboriginal community population and in patients with premature coronary heart disease. This study should provide a greater understanding of the mechanisms involved in the development and progression of atherosclerosis. It is likely that we will find that some inflammatory markers and candidate gene polymorphisms will help identify individuals at increased cardiovascular risk, and who require earlier treatment to prevent disease. In particular, it would focus on preventive therapies that reduce atherosclerosis through anti-inflammatory targets. This study represents a crucial step towards improving our understanding of the aetiology of cardiovascular diseases, and in developing new ways to prevent heart disease and stroke. Progress in these areas will likely have significant public health benefitsRead moreRead less

Summary
One in four adult Australians has the 'metabolic syndrome' (MetS), a clustering of metabolic and heart disease risk factors associated with abdominal obesity. Sympathetic nervous system (SNS) activity is increased in the MetS resulting in enhanced release of the stress hormone 'noradrenaline' . This project will examine the biological and genetic determinants of enhanced SNS activity and the benefits of lifestyle interventions (weight loss, weight loss maintenance and aerobic exercise).

Summary
We will find out whether hours of sun exposure, reported in a standard interview by men with prostate cancer, reduces prostate cancer recurrence and progression. For any effect of sun exposure ithat we observe, we will find out whether it works through vitamin D, which is produced by sunshine on the skin, or is affected by changes in the vitamin D receptor gene, which produces the protein the binds with vitamin D on cells and makes it work.

For any effect of sun exposure ithat we observe, we will find out whether it works through vitamin D, which is produced by sunshine on the skin, or is affected by changes in the vitamin D receptor gene, which produces the protein the binds with vitamin D on cells and makes it work. Prostate cancer is the most common cancer in men in Australia, and this study, using two of the largest collections of clinical outcomes data for this disease, will inform researchers, clinicians and consumers about the possible benefits of sun exposure and Vitamin D in the prevention of recurrence or progression of prostate cancer. On present evidence, these effects are very plausible possibilities. It may also identify sub-groups of men in whom sun exposure or vitamin D might be particularly beneficial in improving outcome of prostate cancer.Read moreRead less
