Summary
There is now no doubting the size and long-term risks to health of the childhood obesity epidemic. However, very little research has examined at population level its immediate consequences for mental health and physical functioning, what pathways confer risk and protection for these consequences, and their likely healthcare consequences. This study will utilise an existing cohort of approximately 1500 Victorian adolescents followed since childhood to examine neglected aspects of the genesis and ....There is now no doubting the size and long-term risks to health of the childhood obesity epidemic. However, very little research has examined at population level its immediate consequences for mental health and physical functioning, what pathways confer risk and protection for these consequences, and their likely healthcare consequences. This study will utilise an existing cohort of approximately 1500 Victorian adolescents followed since childhood to examine neglected aspects of the genesis and impacts of overweight and obesity. The Health of Young Victorians Study was originally assembled in 1997 when the children were in Grades Prep-3. In addition to information on putative risk and protective factors for overweight-obesity and direct measures of height and weight, it is unique in having collected data on health-related quality of life (HRQoL) since children were first recruited during the early primary school years. Eight years after the first wave, the children will be adolescents in Grades 8-11. This third wave will retain a focus on HRQoL. Innovations include study of potential emotional, behavioural and physical consequences of childhood obesity that may in turn affect the natural history of obesity. This large, population-based longitudinal study will redress neglected aspects of child and adolescent overweight-obesity specifically identified in 2003 by the NH and MRC. As well as establishing whether a range of common problems are related to overweight-obesity, it will be able to shed light on mechanisms of adverse outcomes associated with adolescent overweight-obesity, and study protective factors predicting remitting overweight from childhood to adolescence that may inform preventive activities. The study will make an international contribution to knowledge about pathways, prevalence and preventive opportunities for child and adolescent overweight-obesity.Read moreRead less
EPIGENETIC REPROGRAMMING OF MALIGNANT BREAST CANCER

Summary
Poorly differentiated breast cancers are aggressive tumors, frequently resistant to chemotherapy and associated with high morbidity. Herein we propose the engineering of more selective therapeutic agents able to target the genes involved in cancer initiation and resistance to treatment. We aim to correct and reprogram the cancer cell genome in state that is similar to normal, not tumorigenic cells. This work will generate novel forms of treatment for cancers that are presently not curable.

Summary
The insulin-like growth factors are small proteins involved in the growth of most tissues. Their actions are regulated by binding to larger proteins (known as IGFBPs) in the bloodstream and outside the cell. However, some IGFBPs are also found inside cells, where they seem to carry out other functions. We believe that two of these binding proteins, IGFBP-3 and IGFBP-5, change the way cells respond to vitamin A and vitamin D.

Their actions are regulated by binding to larger proteins (known as IGFBPs) in the bloodstream and outside the cell. However, some IGFBPs are also found inside cells, where they seem to carry out other functions. We believe that two of these binding proteins, IGFBP-3 and IGFBP-5, change the way cells respond to vitamin A and vitamin D. These two vitamins are important in cell growth and in the way certain cells perform specialised functions. In test-tube experiments, IGFBP-3 and IGFBP-5 interact directly with the receptors that regulate the effects of these hormones. If the same thing happens inside the cell, IGFBP-3 and IGFBP-5 could change the way these receptors respond to signals from outside the cell. We will investigate what effect these IGFBPs have in living cells and in whole animals and how this may relate to human disease. If we are able to understand how IGFBP-3 and IGFBP-5 affect the way cells respond to vitamin A and D, then we may be able to develop new ways to treat certain human diseases.Read moreRead less
