Summary
Traditionally familial cancers were thought to be caused and inherited by spelling mistakes within the genetic code of cancer prevention genes. Our group has found that a 'chemical coat' around the MLH1 gene, causing it to be switched off, can also be inherited in some cases of bowel cancer, without any mistakes within the gene's code. We will determine if this 'coat' causes other types of cancer and if this runs in families. We also hope to find out how the coat is formed and may be reversed.

Summary
Asthma is more common now in developed countries than it was 20-30 years ago. Many fewer children have asthma in developing countries and there does not appear to have been the same increase in asthma in recent years. Children in developed countries tend to have fewer respiratory infections and recent studies suggest that this may be partly responsible for the increase in asthma. An understanding of why asthma has increased in developed countries may lead to strategies to prevent asthma. In orde ....Asthma is more common now in developed countries than it was 20-30 years ago. Many fewer children have asthma in developing countries and there does not appear to have been the same increase in asthma in recent years. Children in developed countries tend to have fewer respiratory infections and recent studies suggest that this may be partly responsible for the increase in asthma. An understanding of why asthma has increased in developed countries may lead to strategies to prevent asthma. In order to understand the role that respiratory infections may play in the induction of asthma, it is necessary to study babies from birth, documenting each respiratory inflection and monitoring their diet. In a recent large study we have shown that parental reports of common colds and chest infections do influence how many children have asthma at age 6. Also in this study, breast feeding for at least 4 months seemed to be protective against developing asthma. However, we were not able to verify how many infections the children in that study actually had. We are currently studying a population of 236 infants, all of whom are at high risk of developing asthma and allergies. At the end on November 1998, 163 of these infants had reached one year of age. During the first year of life, these infants had a total of 669 respiratory infections, with individual babies having between 0 and 11 infections. We now plan to monitor these children until they turn 5, when we will determine how many have asthma and allergies. In this way we will be able to determine whether children who have more respiratory infections early in life are more or less likely to have asthma and allergies at 5 years of age. We will also be able to tell whether breast-feeding is able to decrease the chance of developing asthma and allergies.Read moreRead less
Neurodegeneration In The Ageing Brain: How The Pathways Leading To Aggregated Protein Cause Disease

Summary
The team consists of eight highly experienced research scientists who are dedicated to solving the question of how the brain degenerates in the elderly when associated with the accumulation of certain proteins: e.g. A_ amyloid (Alzheimer�s disease) and PrP (Creutzfeldt-Jakob disease). Understanding the molecular pathways leading to the degeneration (loss of neuronal synapses) will permit the development of rational diagnostic and therapeutic interventions.

Understanding the molecular pathways leading to the degeneration (loss of neuronal synapses) will permit the development of rational diagnostic and therapeutic interventions. Over the past five years the program has identified several diagnostic and therapeutic avenues which are now being developed by the Pharmaceutical and Biotechnology industries. Much more research is still required for maximizing the chances of success using these approaches.Read moreRead less
The Prevalence And Trajectory Of Kidney Disease In Urban Aboriginal Children

Summary
The Study of Environment and Aboriginal Resilience on Child Health is a major NHMRC funded project looking at the health and illness of urban Aboriginal children in Australia. By working together with Aboriginal Community Controlled Health Services across urban and large regional centres in NSW the study team hope to better understand the causes of common diseases such as kidney and heart disease, and whether these first begin in childhood.
Computational Modelling To Understand Early-stage Neurodegeneration

Funding Amount

Summary
Rather than attempting to reverse neurodegeneration, therapeutic strategies must target the earliest possible stages of disease, when treatments have the potential to prevent or slow down pathological progression. The proposed project will employ computational modelling using functional MRI to deliver highly efficient and sensitive markers of Familial Alzheimer’s disease and Huntington’s disease progression to inform when in the progression of disease clinical trials should take place.
The Causes, Treatment, And Prognosis Of Thyroid Disease

Summary
The thyroid gland controls body metabolism and is crucial to life. Disorders of the thyroid place a severe burden on the health system. Yet despite this, much is unknown about the causes, optimal treatments, and prognosis of thyroid disease. In this NHMRC Early Career Fellowship, Don aims to advance knowledge and improve treatments of these common conditions, focusing on thyroid cancer, Graves’ disease, and Hashimoto’s thyroiditis.

Genetic variants in the microtubule associated protein Tau (MAPT) gene are major risk factors for Alzheimer’s disease and Parkinson’s disease. Environmental or lifestyle factors, such as diet and smoking, have crucial roles in changing the risk of developing these diseases. These environmental factors may exert their influence via a mechanism known as "epigenetics".
