Summary
Every one of your nuclei contain 2 metres of DNA. This DNA is 300,000 times longer than the nucleus itself. In order to fit into this space, while maintaining access to crucial genes, the DNA forms a fantastically ordered three-dimensional structure. This intricate organisation is crucial to health, with even minute changes driving diseases, such as cancer and heart disease. We propose using new technology to understand how this organisation changes during immune cell development and leukaemia.
Molecular Analysis Of Myelodysplasia In The Nup98HoxD13 Mouse Model

Summary
Myelodysplastic syndrome is a preleukemic condition which is poorly understood and occuring at an increasing frequency. Unfortunately no targeted therapy exists. Two features of the disease are abnormal gene expression and abnormal cell death. We have a uniquely accurate model of this disease, and we plan to use it to investigate these two phenomena which will lead to greater understanding of the disease and new molecular targets for therapeutic agents to be developed and tested in our model.
Structure And Composition Of The Pre-T Cell Receptor-CD3 Complex

Summary
In order to recognize a wide variety of pathogens, humans produce many different T cell receptors (TCRs) by the process of gene-rearrangement. However, gene-rearrangement may not always lead to a functioning TCR. We are studying the pre-TCR protein that is responsible for monitoring the success of gene-rearrangement and is thus essential for the formation of a robust immune system. Understanding pre-TCR function will lead to new treatments for immune related diseases.
A Study To Evaluate Safety And Feasibility Of Administrating Zoledronic Acid To Children And Adolescents With Acute Lymphoblastic Leukemia And Lymphoma To Prevent Joint Complication.

Summary
Osteonecrosis (bone death) is a debilitating complication seen following chemotherapy for acute lymphoblastic leukemia in older children. It potentially could lead to destruction of joint, severely limiting quality of life and ultimately requiring joint replacement surgery. Currently there is no effective medical treatment to manage this. Based on our animal experiments we want to study if Zoledronic acid could prevent severe joint destruction in these children and improve their quality of life.
Mechanisms Of Glucocorticoid Resistance In Acute Lymphoblastic Leukaemia

Summary
Glucocorticoids are extremely active drugs used in the treatment of childhood acute lymphoblastic leukaemia (ALL), yet a proportion of patients respond poorly to therapy and exhibit resistance at relapse. Clinically relevant mechanisms of glucocorticoid resistance are poorly understood, principally due to lack of appropriate experimental models. This project will reveal novel mechanisms of drug resistance in childhood leukaemia and lead to novel therapeutic strategies to improve outcome.
Identification And Characterisation Of Novel Genetic Alterations In High Risk Acute Lymphoblastic Leukaemia

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.
New Compounds For Tailored Therapy Against MLL-rearranged Leukaemia

Funding Amount
$326,401.00
Summary
Some of the worst leukaemia survival rates are found in children and adults whose leukaemias display abnormalities of the MLL gene and alternative therapies are therefore urgently required for these patients. The aim of this project is to develop new compounds that specifically inhibit this abnormal gene and in turn inhibit the growth of these cells in the patient. In this way we hope to provide new and more effective therapies for patients affected with this aggressive type of leukaemia.
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.
