Summary
There is a strong link between the incidence of obesity and consumption of sweetened beverages. The proposed studies will characterise (i) the pathway(s) by which sugars signal from the gut to the brain to regulate food intake, (ii) the role of gut peptides in this signalling, and (iii) the variations between individuals in these responses. This information will provide important insights as to why some individuals are more likely to gain weight in response to exposure to diets high in sugar.
Improving The Surgical Outcomes For Barretts-derived Oesophageal Adenocarcinoma Through Early Detection.

Summary
Some people with severe reflux develop Barrett's oesophagus, which puts them at high risk of developing cancer. Patients with Barrett's can be monitored by regular endoscopy to detect cancer early enough so that they can be treated successfully with surgery. The aim of this work is to identify patients who are at highest risk of cancer using molecular biomarkers. We will then determine the cost effectiveness of using biomarkers for surveillance of patients with Barrett's oesophagus.
Scleroderma or systemic sclerosis is a debilitating disease that is characterised by fibrosis of multiple organs leading to organ failure and eventually death. There is currently no cure for the disease. We are beginning to find that a newly-discovered class of molecules, called microRNAs, regulate many disease states but its role in scleroderma has not been established. We aim in this study to identify disease-related changes in microRNAs which may subsequently be used as therapeutic targets.
Novel Strategies In Cancer Cell Invasion In High-density 3D Matrix

Summary
The use of high-density (HD) matrix to study cell invasion sets precedence in mimicking the HD breast tissue condition that pose a real cancer risk. Cell invasion promotes the spread of cancer causing organ failures and death. The aims of this project are to determine the molecular mechanisms and to isolate new regulatory markers of cell invasion into HD matrix. Putative markers will be confirmed by investigating their expression levels in tissue arrays of 195 breast cancer samples.

Summary
Middle ear infection is a highly prevalent paediatric disease characterised by an inflammation of the middle ear and is the most prevalent illness of childhood. It is reported that greater than 80% of children have had at least one episode of acute otitis media by 3 years of age and almost 40% of children have more than 6 episodes by age 7 years. The cause and pathogenesis of middle ear infection are multifactorial and influence of prevalence and chonicity of the infections.

It is reported that greater than 80% of children have had at least one episode of acute otitis media by 3 years of age and almost 40% of children have more than 6 episodes by age 7 years. The cause and pathogenesis of middle ear infection are multifactorial and influence of prevalence and chonicity of the infections. Prevention of bacterial middle ear infection caused by Streptococcus pneumoniae, nontypeable Haemophilus influenzae and Moraxella catarrhalis requires a much better knowledge of how these bacteria interact with each other and with the host. The poor efficacy of the current pneumococcal paediatric vaccine for preventing middle ear infections highlights this deficiency in our knowledge and will impede the development of a suitable multvalent vaccine to prevent infection by the 3 major bacterial pathogens. This study will investigate how the bacteria colonising the respiratory tract interact during infection and how they affect the host.Read moreRead less
Blood Biomarker Discovery For The Diagnosis Of Alzheimers Disease

Summary
Alzheimer's disease (AD) currently affects approximately 24 million people world wide, with >200,000 people within Australia currently affected, by 2050 an estimated 730,000+ people will be affected. The discovery of blood based biomarkers for AD will enable earlier diagnosis of AD, allowing early preventative treatments to be given. Thus, reduce the rate of disease progression and the cost of care and, gain significant improvement in the quality of life for the patients and their families.
Tubulovillous Adenomas In Colorectal Tumorigenesis

Summary
Bowel cancer is the second most common cancer affecting Australians today, and half of all patients will not survive their disease. Bowel cancer grows from small growths called polyps. In this project, we aim to investigate changes in genes found in a particularly aggressive type of bowel polyp called a tubulovillous adenoma. A better understanding of these gene changes will aid the future development of molecular tests for early detection and therapeutic options for the treatment of cancer.

Summary
Bowel cancer is one of the most common cancers affecting Australians. It will affect 1-23 Australians and is a leading cause of cancer-related death. If diagnosed early, bowel cancer is curable with surgery. Unfortunately, symptoms are often not present until the cancer is advanced, when the cure rate is only 55%. It has been recognised that there are different types of bowel cancer depending on different genes which can be inactivated abnormally.

It will affect 1-23 Australians and is a leading cause of cancer-related death. If diagnosed early, bowel cancer is curable with surgery. Unfortunately, symptoms are often not present until the cancer is advanced, when the cure rate is only 55%. It has been recognised that there are different types of bowel cancer depending on different genes which can be inactivated abnormally. We propose that there are at least four different subgroups of bowel tumours, and that each of these may have different physical properties and responses to therapy. We aim to better characterise these subgroups to increase our understanding of how normal bowel can change into a small polyp, that may grow into a cancer. Understanding the gene changes leading to each subtype of bowel cancer will in the future allow the development gene markers for early detection as well as the possibility of individualised patient therapy. We are also studying tiny biopsies of normal bowel tissue from patients either with or without polyps, to try to understand the very earliest changes which may underly the development of a bowel polyp.Read moreRead less
It has been proposed that inflammation plays a major role in prostate cancer risk. We are well placed to test this hypothesis following up evidence from our MCCS and RFPCS studies of associations between inflammatory markers and prostate cancer risk. This proposed project may open for the first time opportunities for the prevention of prostate cancer.
