Summary
Many of the processes that are essential for normal bodily function such as growth, the ability to cope with stress, sexual organ development and metabolism are controlled by the pituitary gland. This organ is located at the base of the brain and regulates these bodily functions through the release of six different hormones. Formation of the pituitary gland occurs during development of the foetus. This process requires a specific set of genes that shape the pituitary and allow the hormone-secret ....Many of the processes that are essential for normal bodily function such as growth, the ability to cope with stress, sexual organ development and metabolism are controlled by the pituitary gland. This organ is located at the base of the brain and regulates these bodily functions through the release of six different hormones. Formation of the pituitary gland occurs during development of the foetus. This process requires a specific set of genes that shape the pituitary and allow the hormone-secreting cells to arise. Changes in these pituitary formation genes results in dysfunction of the pituitary (hypopituitarism) in newborn babies. In severe cases, where the pituitary has failed to form completely, these babies are extremely ill and in some instances do not survive. We are studying families with an inherited form of hypopituitarism in which only male children are affected. This disorder is due to the presence of an extra piece of genetic material (DNA) on the X chromosome. We have recently discovered that one of the duplicated genes, SOX3, causes this disorder. The overall aim of this proposal is to understand how SOX3 causes hypopituitarism by generating a mouse model for this disorder. Analysis of this mouse model will help us to understand the clinical features of hypopituitarism and may allow us to identify previously uncharacterised anatomical defects associated with this disorder. Ultimately,we hope to develop new and improved therapies for hypopituitarism using this mouse model.Read moreRead less
DNA methylation is a process that plays a critical role throughout life by altering the expression of genes. We aim to investigate the potential use of methylation as a target for prevention strategies and for men with no clinical evidence of disease, as a marker of their risk for prostate cancer, particularly its aggressive form.
Development Of Early Warning Systems For Dengue Fever Based On Socio-ecological Factors

Summary
Global climate change has potentially serious effects on the transmission of dengue. An early warning system (EWS) based on socio-ecological factors will be developed to examine where and when outbreaks of dengue are likely to occur and how the future dengue control strategies and prevention efforts need to be applied and strengthened in Australia. This project will provide a platform for future research on developing and implementing an EWS for dengue in the Asia-Pacific region.
Automated Mammographic Measures That Predict Breast Cancer Risk

Summary
Mammographic density (MD) is one of the strongest predictors of breast cancer risk but its impractical measurement prevents its use in a clinical setting. An automated measure of MD would allow screening programs to identify and target women at higher risk of breast cancer which could lead to earlier diagnoses and better breast cancer outcomes. We aim to develop an automated measurement, maximized by its ability to predict breast cancer risk, and applicable to both film and digital mammograms.
