Summary
Signals from growth factors such as cytokines and hormones are required for cell survival. In their absence cells activate an in-built self-destruct process. Determining how cytokines regulate cell death will provide novel targets so that unwanted cells (like cancer cells) can be triggered to die and needed cells (such as brain cells) can survive.

Summary
We propose that in the blood disorders called Myeloproliferative Neoplasms (MPN) there are important changes that affect the function of receptors expressed on the surface of blood cells. These changes will perturb blood cell production and may be able to be targeted effectively with drugs. We will test this using laboratory-based and mouse models of MPN, together with specific drugs that are currently in the clinic, and that inhibit the activity of the key receptors involved.

This approach can be rapidly translated to clinical trial.Read moreRead less

Summary
Acute myeloid leukaemia is a cancer of the blood and bone marrow. We have identified new genes that act with the known oncogene FLT3-ITD in myeloid disease. We will examine in detail how these new genes contribute to the development of AML. This will aid in the development of new therapies for groups of AML patients with these mutations.

Summary
Leukaemia and cancer cells have altered biochemical properties resulting in their high rate of growth compared to normal cells. One of the common biochemical characteristics of cancer-leukaemia cells is augmented activity levels of enzymes called tyrosine kinases. A major group of tyrosine kinase involved in several cancer-leukaemia types is called the Src family of tyrosine kinases.

One of the common biochemical characteristics of cancer-leukaemia cells is augmented activity levels of enzymes called tyrosine kinases. A major group of tyrosine kinase involved in several cancer-leukaemia types is called the Src family of tyrosine kinases. One member of this family called Lyn has been our focus of study for several years, investigating the signalling pathways that it is involved in. This molecule has also been implicated in several specific leukaemia (Chronic Myeloid Leukaemia and Acute Myeloid Leukaemia) as well as cancer (Prostate, Colon, Breast) in recent years. We have identified a novel mechanism of down-regulation of this enzyme mediated by an adapter molecule called Cbp, which recruits the Lyn inactivating molecules Csk-Ctk as well as SOCS-1; together they inhibit the activity of Lyn and degrade the enzyme. Using our knowledge of the essential interaction elements of Cbp we will design and test various mini-Cbp molecules for their ability to inactivate and degrade Lyn in leukemic and cancer cells. These molecules may allow us to develop novel therapeutics capable of inactivating-degrading specific tyrosine kinases in cancer and leukaemia.Read moreRead less
Characterisation Of CBF Acute Myeloid Leukaemia By MicroRNA Profiling

Summary
Recent studies have demonstrated the existence of small pieces of previously undescribed genetic material, known as microRNAs (miRNAs), which are thought to have critical functions across various biological processes and regulatory pathways in cells. This project aims to examine the role of these miRNAs in the development of abnormal cellular proliferation that leads to leukaemia, by examining the expression of all known miRNAs in the abnormal cells of our patients with leukaemia.
Molecular Pathways Mediating Quiescence And Resistance In Leukaemia Stem Cells In Acute Myeloid Leukaemia.

Summary
Acute myeloid leukaemia (AML) is a devastating cancer of the blood and bone marrow which is rapidly fatal unless effectively treated with chemotherapy. AML is caused by genetic events that alter normal blood stem cells to give them a growth and survival advantage and also may confer resistance to chemotherapy in some cases. We will evaluate and target the mechanism of this resistance in laboratory models. This information can then be used to design new treatments to improve outcomes in AML.
Roles Of The EMT Transcription Factors In Epigenetic Remodelling And Myeloid Cell Transformation.

Summary
This project is based upon our novel discoveries that identified ZEB2 and SNAI1 as novel genes involved in the development of aggressive forms of blood cancer. During the course of this proposal we will find new drug targets and new drug treatment options using existing drugs that will specifically target cancer initiating cells in order to kill aggressive forms of blood cancers that are currently refractory to treatment.
The Role Of Oncogenes, Cell Death Machinery And Novel Players In The Regulation Of Hematopoietic Stem Cells, Leukemogenesis And Hematological Disorders

Funding Amount
$763,409.00
Summary
This project is focused on the regulation of blood cells and the diseases that arise when they become defective, such as bone marrow failure and leukemia. It will investigate how proteins involved in cell suicide impact on blood cell survival, cancer therapy, and the formation of blood clots. The link between cancer genes and stem cells will be examined. Ultimately, the aims are to identify drug targets in hematological disorders, and develop new drugs to promote the survival of healthy cells.
