Radiotherapy (RT) is a curative anti-cancer treatment employed in around half of all cancer sufferers. Very occasionally, a cancer patient will manifest an unexpected adverse reaction to RT and there is strong evidence for a genetic basis to such RT sensitivity. Despite two decades of research, such reactions cannot currently be predicted prior to treatment and their occurrence limits the intensity, and hence cure rates, of RT for the majority of patients.

Very occasionally, a cancer patient will manifest an unexpected adverse reaction to RT and there is strong evidence for a genetic basis to such RT sensitivity. Despite two decades of research, such reactions cannot currently be predicted prior to treatment and their occurrence limits the intensity, and hence cure rates, of RT for the majority of patients. This project will employ cutting edge technology (DNA Chips, or microarrays) to attempt to understand why some patients suffer significant RT side-effects, while the vast majority do not. We have developed a tissue bank of samples from cancer patients who have had adverse RT reactions, and these samples (and samples from unaffected cancer patients) will be examined by microarrays: the activity of thousands of genes will be evaluated in each experiment, and we shall search for patterns of gene activity which track with RT sensitivity. Should we determine a pattern, this pattern will be checked against a larger number of cases and if it accurately predicts RT sensitivity, could lead to the routine testing of cancer patients prior to RT and the individualisation of cancer therapy. In parallel, we will evaluate the tissues of sensitive patients with assays capable of detecting abnormalities in the response to radiation, which may give clues as to an underlying gene fault(s) which might predispose to radiosensitivity in that individual.Read moreRead less
MicroRNA Expression Profiling Of Eutopic Endometrium In Women With Versus Without Endometriosis

Summary
Endometriosis is a medical condition where endometrium grows outside the womb. About 10% of women have this condition that can cause abdominal pain, painful periods and difficulty conceiving a child. Now endometriosis can only be diagnosed by surgical procedure. We believe that the presence of endometriosis causes particular small molecules called microRNAs to be present in the lining of the womb or in the blood only in women with endometriosis, and we could develop a test for endometriosis with ....Endometriosis is a medical condition where endometrium grows outside the womb.

We believe that the presence of endometriosis causes particular small molecules called microRNAs to be present in the lining of the womb or in the blood only in women with endometriosis, and we could develop a test for endometriosis without resorting to surgery.Read moreRead less
Genomic Characterisation Of Asbestos Related Lung Cancer

Summary
Lung cancer causes more deaths in Australia than any other cancer. Smoking is the main cause, but people exposed to asbestos are also at risk, and it can be difficult to know whether a case is due to tobacco, asbestos or both. We will study lung cancer genes in people with asbestos exposure to find whether asbestos lung cancer has a specific pattern of abnormal genes (signature). If so, this could help people entitled to compensation, and also point to new treatments for asbestos lung cancer
Defining The Cellular Basis For Therapeutic Angiogenesis: Characterisation Of Endothelial Progenitor Cell Populations

Summary
Cardiovascular disease is the leading cause of death in the Australia. Endothelial progenitor cells (EPCs), similar to stem cells, have strong self-renewal capabilities and the ability to mature further. There has been immense interest in using EPCs as they are believed to have a role in the growth and repair of blood vessels. This research systematically studies two candidate EPCs, the early EPC and the outgrowth EPC (OEC), and potentially paves the way for using EPCs to treat heart disease.
Understanding The Role Of Sex Hormones In Mental Illness

Summary
Evidence suggests that the female hormone, estrogen, protects against schizophrenia, although the exact mechanism of action underlying this effect is unclear. We believe that by measuring estrogen-induced changes in the levels of genes in the brain, we will identify the way that estrogens protect against the symptoms of schizophrenia and improve antipsychotic treatment response.
