A fundamental study of the role of signal transduction pathways in the regulation of Chlamydia's complex developmental cycle. Chlamydia are unique organisms in the microbial world. They are among the smallest bacteria and yet have a complex two-stage developmental cycle. In addition they are major causes of disease in animals and humans with no vaccines available. We have used the recent flood of full genome sequence data to identify over 30 new cell signalling proteins. By understanding how the ....A fundamental study of the role of signal transduction pathways in the regulation of Chlamydia's complex developmental cycle. Chlamydia are unique organisms in the microbial world. They are among the smallest bacteria and yet have a complex two-stage developmental cycle. In addition they are major causes of disease in animals and humans with no vaccines available. We have used the recent flood of full genome sequence data to identify over 30 new cell signalling proteins. By understanding how these cell signaling proteins are organized into pathways and how this microorganism controls its complex growth and developmental cycle, we will be able to develop novel methods of control. We are at the fore front of international research and therefore uniquely placed to conduct this project.Read moreRead less

Summary
The insulin-like growth factors are small proteins involved in the growth of most tissues. Their actions are regulated by binding to larger proteins (known as IGFBPs) in the bloodstream and outside the cell. However, some IGFBPs are also found inside cells, where they seem to carry out other functions. We believe that two of these binding proteins, IGFBP-3 and IGFBP-5, change the way cells respond to vitamin A and vitamin D.

Their actions are regulated by binding to larger proteins (known as IGFBPs) in the bloodstream and outside the cell. However, some IGFBPs are also found inside cells, where they seem to carry out other functions. We believe that two of these binding proteins, IGFBP-3 and IGFBP-5, change the way cells respond to vitamin A and vitamin D. These two vitamins are important in cell growth and in the way certain cells perform specialised functions. In test-tube experiments, IGFBP-3 and IGFBP-5 interact directly with the receptors that regulate the effects of these hormones. If the same thing happens inside the cell, IGFBP-3 and IGFBP-5 could change the way these receptors respond to signals from outside the cell. We will investigate what effect these IGFBPs have in living cells and in whole animals and how this may relate to human disease. If we are able to understand how IGFBP-3 and IGFBP-5 affect the way cells respond to vitamin A and D, then we may be able to develop new ways to treat certain human diseases.Read moreRead less
Identification Of Germline Variation That Predicts Progression Free Survival Following Chemotherapy For Advanced Ovarian Cancer

Summary
Women diagnosed with ovarian cancer typically undergo surgery, followed by chemotherapy. However, the efficacy of chemotherapy varies widely, with some women responding well, whilst others are exposed to the toxic effects of a treatment that does them little good. We aim to identify the genes which explain why there are differences in response. This will lead to more individualised chemotherapy and improved outcomes for women with ovarian cancer.
The role of human single-stranded binding protein (hSSB1) in DNA damage repair and tumorogenesis. Cancer is a leading cause of disease related death world wide, accounting for over 13% of all deaths in 2007. Approximately 38,000 people died in Australia from cancer in 2005. Cancer results from a single cell losing a vital part of its genetic information, this results in the cell losing its normal programming and initiates a process of rapid growth and multiplication.

Cancer is a leading cause of disease related death world wide, accounting for over 13% of all deaths in 2007. Approximately 38,000 people died in Australia from cancer in 2005. Cancer results from a single cell losing a vital part of its genetic information, this results in the cell losing its normal programming and initiates a process of rapid growth and multiplication. This research project aims to look at the mechanisms that exist to prevent this initial loss of genetic material within an individual cell. It further aims to translate theses discoveries into the clinic, providing new tools for diagnosis and prognosis of specific cancers and to establish links with major pharmaceutical companies to develop novel anticancer therapies.Read moreRead less

Signalling cross-talk through Suppressors Of Cytokine Signalling (SOCS) initiates luteolysis in the ovary. Members of the newly discovered SOCS protein family block cytokine signal transduction pathways, including those for prolactin and GH. We have discovered that one of these proteins, SOCS-3, is upregulated in the corpus luteum of the ovary by prostaglandins and propose that induction of prolactin or GH resistance is a hitherto unrecognised and critical step in luteolysis.

We have also discovered that this cross-talk between prostaglandin- and cytokine-receptor signalling pathways occurs in preadipocyte and breast cell lines and propose that this research will serve as a paradigm for understanding how sensitivity to cytokines can be controlled at a molecular level.Read moreRead less

This project aims to develop a novel, low activation and liquid helium-free superconducting solution with superior electromagnetic, mechanical and thermal properties for use in fusion reactors. Superconducting magnets and their associated cryogenic cooling systems represent a key determinant of thermal efficiency and the construction/operating costs of fusion reactors. The project expects to overcome these barriers so that widespread uptake of these reactors becomes viable. Outcomes from the project will include a fundamental understanding of pure and doping-induced isotopic magnesium diboride superconductors and their behaviour under high neutron flux and harsh plasma atmosphere, which are specifically designed for application in next-generation, low-cost fusion reactors.Read moreRead less
