Summary
The Indigenous people of Central Australia have the highest reported prevalence of bronchiectasis in the world. In a recent study, we found infection with Human T -cell Lymphotropic Virus type 1 (HTLV-1) may contribute to the devlopment of bronchiectasis. The present study seeks to confirm this association and to determine whether increased HTLV-1 activity is associated with greater risk. This will require the development of assays that will improve diagnosis and assist in determining prognosis ....The Indigenous people of Central Australia have the highest reported prevalence of bronchiectasis in the world.

Role Of The Inositol Polyphosphate 4-phosphatase Type 2 In Human Breast Cancer

Summary
Breast cancer is the most invasive cancer in females, affecting 1 in 9 women before the age of 85. Normally cells only divide when they receive a stimulus from a hormone or growth factor. The PI3K pathway responds to these stimuli and has been implicated in cancer when cells divide uncontrollably and invade surrounding tissue. We have identified a potential cancer suppressing gene, 4-ptase-2 that turns off the PI3K growth signals. We aim to characterize the role of 4-ptase-2 in breast cancer.
Functional Analysis Of The Roles Of The Serine Protease Kallikrein 7 And Its Variant Isoform In Serous Ovarian Cancer.

Summary
Ovarian cancer is the leading cause of death from gynaecological cancers with 1,200 women in Australia diagnosed with the disease in 2004, and 852 patients dying of ovarian cancer. The mortality rate has improved little over the last two decades with one of the major reasons being that ovarian cancer is often diagnosed at a late stage when cancer cells have spread into the abdomen or metastasised to other sites. The kallikrein family of serine proteases or enzymes is emerging as very useful diag ....Ovarian cancer is the leading cause of death from gynaecological cancers with 1,200 women in Australia diagnosed with the disease in 2004, and 852 patients dying of ovarian cancer. The mortality rate has improved little over the last two decades with one of the major reasons being that ovarian cancer is often diagnosed at a late stage when cancer cells have spread into the abdomen or metastasised to other sites. The kallikrein family of serine proteases or enzymes is emerging as very useful diagnostic or prognostic biomarkers for ovarian cancer as they often have higher levels in ovarian cancer tissue compared to the normal ovary. One of these enzymes is kallikrein 7, which is also involved in shedding of skin cells. Because of its involvement in skin, we hypothesise it may be playing a similar role in ovarian cancer and helping the cancer cells to detach from the ovary so they are free to move around the body to other sites. There are two different forms of kallikrein 7, a long form and a shorter form which is lacking a part that is crucial to enzymatic activity. While low levels of the short form have been found in normal ovary, very high levels of both forms were seen in ovarian cancer, especially the serous subtype which is the most common and most aggressive form of ovarian cancer. The aim of this project is to determine the function(s) of both forms of kallikrein 7 in ovarian cancer and to identify other molecules-proteins they are involved with. These findings will tell us if kallikrein 7 is involved in the spreading of ovarian cancer cells or metastasis and will lead to a better understanding of the development and progression of ovarian cancer. The finding from this study may also lead to better therapeutic approaches (ie blocking the action of Kallikrein 7), and-or markers to monitor ovarian cancer progression.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

Summary
The deadly asbestos-induced cancer mesothelioma is continuing to kill tens of thousands of people each year. Most patients are diagnosed with advanced disease. In this study we will use novel biomarkers to help the diagnosis of mesothelioma and potentially improve treatment options for patients.
Biomarkers For The Diagnosis Of Childhood TB: Validation In A High TB Prevalence Setting

Funding Amount

Summary
The WHO highlights the urgent need for new diagnostic tests to combat the global TB pandemic. Diagnosis of TB is particularly difficult in children. In our previous NHMRC-funded Melbourne-based study we found promising diagnostic markers in blood which can differentiate patients with and without TB. This project has the potential to revolutionise the diagnosis of TB by providing data that will enable the development of a new generation of diagnostic tests.
Tackling Key Epidemiological And Basic Scientific Research Issues In Prion Diseases.

Funding Amount

Summary
Proposed Practitioner Fellowship research will simultaneously include epidemiological and basic scientific projects, emphasising human prion disease. Epidemiological research will involve large-scale studies to clarify genetic factors that influence susceptibility to developing prion disease, as well as clarify whether Alzheimer disease is transmissible, while basic scientific research will include determining the characteristics of the misfolded prion proteins causing neuronal disease.
