Summary
Bowel cancer is a major health issue but is also a preventable disease. Identifying who has a high risk of developing bowel cancer from someone who has a low risk is an important way to ensure preventative medical treatment is targeted to those who are at the highest risk and will ultimately save lives. I will utilise different genomic profiling approaches to identify risk factors for bowel cancer so that they can be used to identify high risk people in the population.
Circadian Mechanisms For Sex Differences In Shift Work Tolerance

Summary
It is well-established that women respond more poorly than men to shift work schedules, having more health complaints, more drowsiness and more accidents at work than men. The physiological cause of this sex difference is not known. Our research suggests that differences in the circadian rhythms of women and men may promote shift work intolerance in women. This study is designed to examine sex differences in the effect of office-level light on the biological clock during a simulated night shift.
New High-risk Variants For Colorectal Cancer: The Post-GWAS Era

Summary
Our aim is to discover new genes that greatly increase bowel cancer risk. If we can identify these carriers we may be able to prevent them getting cancer. By studying DNA related to bowel cancer, using a novel family design, we will identify families most likely to carry the new genes. We will focus genetic testing, using new techniques, to look for mutations in these prioritised families. Identified mutations will be tested in a 3,500 bowel cancer cases to see how important they are.
Functions Of FZD7 In The Intestine And Colorectal Cancer

Summary
Wnt proteins are a family of signaling molecules that are critical for the function of normal and cancerous epithelial cells in the gut. However, the cell surface receptor that transmits Wnt signals is not known. Our research strongly implicates one Wnt receptor (FZD7). Here we test this using innovative mouse and cell line models. We wish to understand how Wnt-driven processes are activated. This knowledge will lead to novel avenues to block aberrant activation of Wnt signalling in cancer cells
Development Of A Comprehensive Model For Colorectal Cancer Risk Prediction

Summary
Bowel cancer is the second most common cause of cancer death in Australia. While the average lifetime risk is 1 in 20, this is a great difference in individual risks. Screening and early detection can prevent 90% of bowel cancer deaths. We need to know who is at high-risk and therefore can be targeted for screening. In this project, I will develop the first tool that can predict precisely an individual’s personal risk of bowel cancer.
Alpha-particles linked to recombinant antibodies targeting tumour cells have potential to effectively treat tumours while minimising normal tissue side effects. We will explore a novel alpha-particle therapy approach to solid tumours, by delivering 225Ac directly into tumour cells, or into cells that support the tumour (microenvironment). This approach will hopefully result in development of a new approach to treatment of cancers that are resistant to conventional therapies.
About 14,000 cases of bowel cancer occur annually in Australia despite the availability of life-saving screening. Most people do not receive recommended screening colonoscopy. We will look at why people at high-risk avoid screening and why people at average risk seek unnecessary screening. We will analyse family history and contacts with the healthcare system that impact screening decisions. We will determine the impact of screening on reducing the number of new cases and deaths.
Understanding The Metabolic Consequences Of Impaired AMPKa2 And NNOS� In Skeletal Muscle: Implications For The Metabolic Syndrome

Summary
The inability of muscle to utilise sugar from the blood is a major problem that contributes to obesity and Type 2 diabetes. Since the number of people with these diseases will at least double by 2030, we need to find out what causes this problem. We will examine whether two muscle proteins that are impaired in obesity and Type 2 diabetes are also responsible for impaired sugar utilisation. We think that increasing these muscle proteins will fix the _sugar problem�, and remedy these diseases.
Enabling Personalised Risk Assessment For Colorectal Cancer

Summary
Bowel cancer screening will be most effective in disease prevention if it is applied proportionately to individual person's risk. Risk-based screening requires a risk calculator to assess personal risk. By utilising existing large, international datasets, I will identify the risk factors specific for different bowel cancer types and incorporate them to upgrade the prediction model that I have developed. This will achieve more accurate risk prediction to enable personalised risk-based screening.
Young Onset Colorectal Cancer: Genetics Pathology And Environment

Summary
There has been a steady increase since 2002, in the age-standardised incidence of CRC in males under 45 years in Australia, contrasting with the stabilisation in incidence of CRC in males of age 45 years and over. Persons under 50 years are not routinely screened unless they have a significant family history of CRC. Young-onset rectal cancer is associated with late presentations and with a higher mortality. This proposal will address the possible risk factors for young-onset CRC.
