Summary
We propose that subtle, heritable changes in the expression or function of genes that are switched off, or on, early in the development of ovarian tumours, may predispose the individual to ovarian cancer. We will are carry out a large study of the most common subtype of ovarian adenocarcinoma, serous invasive tumors, in order to identify genes that affect a woman's risk of ovarian cancer.

We will are carry out a large study of the most common subtype of ovarian adenocarcinoma, serous invasive tumors, in order to identify genes that affect a woman's risk of ovarian cancer. Identification of women at elevated risk for ovarian cancer on the basis of their genotype will allow them to be targeted for screening, and for intervention studies, as well as providing fundamental insight into the etiology of ovarian cancer.Read moreRead less
Risk Factors For The Development Of NAFLD Beyond Insulin Resistence: Genetic, Developmental And Environmental Influences

Funding Amount
$662,052.00
Summary
Nonalcoholic fatty liver disease (NAFLD) is the presence of fat within the liver and is associated with obesity and diabetes. NAFLD occurs in approximately one in seven Australian adolescents and may lead to cirrhosis and endstage liver disease. This proposal aims to determine what genetic and developmental risk factors lead to NAFLD, in addition to examining the role of diet and exercise. This information will lead to better treatments for this condition.
Identification Of Novel Low Penetrance Genes Associated With Melanoma Risk

Summary
Using pools of DNA samples we will conduct a genome-wide association study for melanoma predisposition genes. The most promising candidate genes will be followed up by sequencing and further geneotyping of additional SNPs in order to identify the causal variants.
Memory, Synaptic Plasticity And Gene Networks In Schizophrenia

Summary
Schizophrenia affects about 1% of the population. Its typical progression over a lifetime leads to long-term impairment of cognition, reality distortion, and an impoverished quality of life. Most likely, multiple genes, interacting together or with environmental factors, are involved. Using a novel approach to its partition, WA researchers aim to unravel complex networks of genes affecting memory and brain function in a cognitive deficit subtype of schizophrenia they have identified recently.

Summary
The gastrointestinal tract is a major portal of entry for dietary chemicals and drugs taken orally or as suppositories. Enzymes resident in the gastrointestinal tract have an essential role in preventing these chemicals from reaching other organs and target tissues in the body and in protecting the gastrointestinal tract per se from their effects. The levels of these enzymes in the gastrointestinal tract varies quite extensively between individuals. In this project we will determine how these en ....The gastrointestinal tract is a major portal of entry for dietary chemicals and drugs taken orally or as suppositories. Enzymes resident in the gastrointestinal tract have an essential role in preventing these chemicals from reaching other organs and target tissues in the body and in protecting the gastrointestinal tract per se from their effects. The levels of these enzymes in the gastrointestinal tract varies quite extensively between individuals. In this project we will determine how these enzymes are regulated and what causes the large differences in their levels between individuals. This will help us to predict those individuals who are more at risk from the adverse effects of drugs taken orally or as suppositories and from the toxic effects of chemicals in the diet. The project will also help us identify therapies that can increase the levels of these protective enzymes to help reduce the effects of exposure to toxic chemicals .Read moreRead less
Geelong Osteoporosis Study: Fracture Risk Prediction Based On Twenty Years Of Prospective Data.

Funding Amount
$1,107,758.00
Summary
In this population-based study we will generate evidence, both environmental and genetic, for defining fracture risk in Australian men and women. This will help identify individuals likely to sustain fragility fractures so that suitable therapies can be recommended. The data will be useful for developing prognostic models in both a clinical setting and for genetic screening programmes.
Kallikrein Gene Variants In Prostate Cancer: Analysis Of Gene Regulation And Diagnostic/Prognostic Use

Funding Amount

Summary
Prostate cancer is the most common male cancer in Australia. However, early detection through screening programs has proven challenging, and about 30% of the 10,000 new cases diagnosed annually already have advanced disease. Hence, there is a fundamental need for increased basic research in prostate cancer etiology (cause) and tumour biology, and a critical requirement for methods that will assist in earlier detection of the disease and predict progression.

However, early detection through screening programs has proven challenging, and about 30% of the 10,000 new cases diagnosed annually already have advanced disease. Hence, there is a fundamental need for increased basic research in prostate cancer etiology (cause) and tumour biology, and a critical requirement for methods that will assist in earlier detection of the disease and predict progression. A family of proteins called kallikreins (including prostate specific antigen, PSA) are often associated with clinical features of prostate cancer. We will characterise genetic variants (polymorphisms) in kallikrein genes that are consistently over-produced in prostate cancer, and determine whether they cause more protein to be produced in cells grown in the laboratory and in tumour tissue, and-or give rise to different expression products or splice variants. We will use bioinformatics (computer programs) to characterise published kallikrein gene sequences and to examine them for genetic variants that might be related to changes in gene expression or to splice variants. We will then use a case-control study, involving 1200 men with prostate cancer and 1200 healthy men, to determine whether these gene variants are associated with an increased risk of prostate cancer or with clinical aspects of the disease. Finally, we will examine the functional significance of the gene variants. This project represents an important and novel combination of molecular biology with the study of clinical disease at the population level, in the relatively new field of molecular epidemiology. It will clarify the role of kallikrein gene variants in prostate cancer risk and progression. The technologies may ultimately prove useful clinically for diagnosis of prostate cancer or for monitoring of treatment and prognosis, and hopefully will assist in clinical decision-making.Read moreRead less
Regulatory RNAs Underlying Genetic Associations With Ankylosing Spondylitis

Summary
Ankylosing spondylitis is a chronic inflammatory disease affecting the spine and causing back pain. The diagnosis of the disease is delayed by up to 10 years due to lack of accurate tests. We aim to identify molecular signatures of the disease that might be used to distinguish inflammatory processes typical of the disease and other causes of back pain. This would allow earlier and more accurate diagnosis of the disease and result earlier patient treatment and better health outcomes.
