Summary
Acute lymphoblastic leukemia remains one of the leading causes of death in children and outcomes for adults with this disease remain poor. This project examines how manipulation of the environment where leukemia arises can be used to therpaeutic advancage. Acute lymphoblastic leukemia cells are highly dependent on the support provided by bone marrow cells but the mechanisms are not well understood. Disrupting signals from the bone marrow cells has potential as a therapeutic strategy.
Harnessing RNA Interference In Gene Therapy Vectors For ?-thalassaemia

Summary
There is an urgent need to develop safe and effective treatments for ?-thalassaemia. We anticipate that ?-globin-specific RNAi sequences will synergise with ?-globin transgene expression to achieve balanced ?-/?-globin ratio in a clinical setting. Given that one of the major issues with current gene therapy vectors is achieving high levels of expression, we believe this will be a more effective gene therapy strategy than ?-globin transgene expression alone.
Molecular Regulation Of Haematopoiesis In Health And Disease

Summary
The blood forming system coordinates production of cells that confer immunity to infection, transport oxygen and assist blood clotting. When the molecular mechanisms that control these functions go awry, diseases including leukaemia and autoimmunity result. This research will define fundamental molecular regulators of blood cell production and function, assess their role in blood cell diseases and explore their potential to provide leads for development of new therapeutics.
A Newly Identified Role For 14-3-3zeta Protein In Thrombosis And Platelet Procoagulant Activity

Summary
Cardiovascular disease, including heart attack and stroke is the major cause of death globally, and is responsible for the death of 50,000 Australians each year. Platelet activation and blood coagulation play an important role in these diseases and we have discovered that a protein called 14-3-3 zeta is important in the processes that result in thrombosis. We are studying the mechanisms by which this protein contributes to life-threatening platelet activation with the aim of developing new and m ....Cardiovascular disease, including heart attack and stroke is the major cause of death globally, and is responsible for the death of 50,000 Australians each year.

Summary
T-cell acute lymphoblastic leukaemia (T-ALL) results from the abnormal development of T cells that are an important cell type in the body's immune system. Although the prognosis for T-ALL has improved remarkably over the last decade, for one out of five T-ALL cases the underlying genetic defects remain unresolved and are refractory to current therapies. This project aims to use both novel mouse models and human patient cell lines to better understand this disease and discover novel targets for f ....T-cell acute lymphoblastic leukaemia (T-ALL) results from the abnormal development of T cells that are an important cell type in the body's immune system.

Is Hypoxia Inducible Factor 2 The Trigger Of The Angiogenic Switch And A Driver Of Disease Progression In Myeloma?

Summary
Multiple myeloma (MM) is a fatal cancer of plasma cells (PC). PC migrate to the bone marrow, which compared with other organs is low in oxygen (hypoxic). In response to this hypoxia, the cancer cells turn on the expression of genes called hypoxia-inducible factors (HIF). HIFs activate the expression of genes that encourage blood vessel formation, which in turn stimulates greater tumour growth and disease progression. This proposal will investigate the role of HIFs in the progression of MM.
Eradicating Leukaemic Stem Cells By Targeting The Arginine Methyltransferase PRMT5

Summary
Acute leukemia is a devastating cancer arising from primitive cells in the bone marrow called stem cells. We have identified a protein (PRMT5) that is highly expressed in leukemia stem cells. Our preliminary experiments suggest that blocking the function of this protein with a novel drug can stop the growth of these cells. This project will use a variety of mouse models of acute leukemia to determine how PRMT5 keeps stem cells alive and whether this drug will be a valuable new treatment.
