Summary
Acute lymphoblastic leukaemia (ALL) remains the leading cause of cancer-related death in children and young adults. The goal of this research is to identify genetic abnormalities that contribute to treatment failure in high-risk ALL. In addition to providing insights into the biologic basis of ALL, this work has the potential to result in new diagnostic tests, predict response to chemotherapy, and identify new strategies to improve the treatment outcome for ALL patients.
Role Of Connective Tissue Growth Factor In The Pathobiology Of Lymphoid Tumours And Response To Therapy

Summary
Leukaemia is the most common cancer in children and the improved cure rates are among the major biomedical advances of the past five decades. However, we still do not fully understand why leukaemia cells have a growth advantage. We identified the growth factor CTGF as being massively activated in leukaemia cells. The project aims to study the role of CTGF in bringing about the disease. Insights gained are expected to lead towards novel treatments for patients with leukaemia.
Genome-wide Epigenetic Analysis Of Childhood Acute Lymphoblastic Leukaemia

Summary
Of all cancers in children, Acute Lymphoblastic Leukaemia is the most common. To date, the causal mechanism(s) for leukaemia in children remain unclear. Although 5-year event-free survival rates are relatively high (up to 80%) it is still unclear why children expected to survive with a good prognosis, succumb to the disease. Therefore, there is still a need to further refine current diagnosis and prognosis parameters that will together lead to improved outcomes to children with leukaemia.
Targeting Drug-Resistance In Paediatric Acute Lymphoblastic Leukaemia

Summary
Leukaemia is the most common type of cancer in children but resistance to therapy continues to be a significant problem. This project will investigate the biology of drug-resistance and relapse using a mouse model that replicates the human disease. We hope to identify novel therapeutic targets that can be used in combination with existing therapies to improve outcomes in this disease, particularly for patients that develop drug-resistance such as those at the time of relapse.
Translational Research Program To Advance Clinical Outcomes In Acute Myeloid Leukaemia

Summary
Five-year survival in acute myeloid leukaemia (AML) is only 27%, placing it amongst the worst-ranked cancers for clinical outcome. Improved patient outcomes will be achieved through implementation of a Translational Research Program to support novel agent drug testing, early-phase and randomised clinical trials and a national clinical registry to audit outcomes. New insights into leukaemic stem cell function and mechanisms of drug resistance will inform the design of future clinical trials.
Antigen Receptor As Oncogene: Understanding CARD11 Mutations In B Cell Malignancy

Summary
More than 5000 Australians are newly diagnosed as lymphomas. Recent technology identified many candidate genes for lymphomas, however it still remains unclear how each mutated gene distorts signalling molecules inside tumours cells. By introducing one of recurrent mutated genes, CARD11 into mouse B cells, we will examine how this mutation affects normal signalling pathways and B cell functions. We hope this project will provide a guidance to use forthcoming drugs to target specific molecules.
Overcoming The Differentiation Block In Acute Myeloid Leukaemia

Summary
Acute myeloid leukaemia (AML) is an aggressive leukaemia with poor overall survival. About 50% of AML cases have genetic mutations that disable PU.1, which in turn alters the expression of many other genes that cause leukaemia. We have developed new AML models allowing reversible inhibition of PU.1, and have shown that re-engaging PU.1 function causes AML regression. This project aims to understand PU.1 functions in AML and identify rational drug targets for treatment-resistant disease.
Chronic Lymphocytic Leukemia (CLL) is a very common blood cancer. Leukaemic tumour cells actively shut down key immune defences in patients who are very prone to severe infections. Current chemotherapies further immuno-compromise CLL patients and over a quarter will die from an infection despite having responded to cancer treatments. We propose that restoring key immune functions in CLL is key to improve resistance to infection and restore natural anti-cancer immunity.
Understanding The Multistep Pathogenesis Of T-cell Leukaemia

Summary
Lmo2 is a transcription factor whose overexpression is a common cause of T-cell leukaemia. This project seeks to identify downstream targets of Lmo2 that cause T-cell leukemia. In addition, the origins and effects of secondary mutations that collaborate with Lmo2 in causing T-cell leukaemia will be determined. This will improve our understanding of how T-cell leukaemia develops and provide new molecular targets for therapy.
Individualising Tyrosine Kinase Inhibitor Therapy In CML To Facilitate Successful Treatment Free Remission

Summary
This project will determine the optimal therapy for patients with chronic myeloid leukaemia (CML), matching the most appropriate drug to the individual patient, based on each patient's unique biology, thereby maximising the chance of cure. Furthermore, this project will develop novel highly sensitive tests for the presence of residual disease, even if undetectable by current techniques. This will enable crucial, timely treatment changes to be made with curative intent.
