Summary
Myelodysplastic Syndromes (MDS) are a group of blood stem cell disorders that result in low blood counts and leukemia especially in the elderly. Azacitidine (AZA) is a drug that improves blood counts and delays progression to leukemia and is the treatment of choice. However, only half the patients treated with AZA ever respond and half of the responders relapse within a year. We will describe the origins of MDS and the basis for drug response, resistance and disease relapse.
Epigenetic Regulation Of Self-renewal Signalling Pathway In Leukemic Stem Cell Formation

Summary
Acute myeloid leukaemia (AML) is a fatal form of blood cancer. The survival of patients with AML remains poor and this is due to the return of disease after chemotherapy (relapse). Leukemic stem cells (LSCs) are the major cause of relapse and we study how LSCs are regulated. This will provide valuable input into the development of novel therapeutic strategies to target therapy-resistant LSCs and improve AML outcome.
Investigating The Transcriptional Circuitry Of Normal Human Haematopoietic And Leukaemic Cells

Summary
Despite improvements in supportive care, more than half the patients diagnosed with acute myeloid leukaemia (AML) succumb to complications associated with the disease or its treatment. To improve treatment outcomes, we need to understand how leukaemic cells self-renew and how this differs from normal blood stem cells. Our proposal aims to do this by using computational and experimental methods to identify and validate factors to which leukaemic cells are more dependent than normal blood cells.
Discovery Of New Targets For Therapy That Kills Non-dividing Cancer Stem Cells

Summary
I am a clinical haematologist that specialises in treating patients with a terrible form of blood cancer, acute myeloid leukaemia. Survival rates for this disease have not changed for 30 years and we now realise this is because we are not targetting the queen bee of the cancer - the cancer stem cell. In this project I am looking for cell markers that are only present in rare, truly latent non-dividing cancer stem cells effectively change a remission into a cure.
Targeting The EGFR And C-Met Tyrosine Kinase Receptors In Myeloproliferative Neoplasms

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 ....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.

This approach can be rapidly translated to clinical trial.Read moreRead less
Roles Of The EMT Transcription Factors In Epigenetic Remodelling And Myeloid Cell Transformation.

$809,520.00
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.
Translational Research Program To Advance Clinical Outcomes In Acute Myeloid Leukaemia

Funding Amount

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.
Targeting Epigenetic Enzymes In Core Binding Factor AML

Summary
Acute myeloid leukemia (AML) is a devastating disease and there are ~900 new cases diagnosed annually in Australia. A subset of AML, called core binding factor (CBF) AML is more responsive to conventional chemotherapies than other AMLs however patients still relapse indicating a need for new therapies. We will use preclinical models of CBF AML to identify the proteins and pathways that these leukemias are “addicted” to in order to develop new treatment options for these patients.
GADD45A Promoter Methylation And Poor Prognosis In AML:mechanism And Clinical Significance

Funding Amount
$706,280.00
Summary
DNA methylation associated with the GADD45A gene defines an AML patient group with poor overall survival and limited treatment options. We will investigate the significance of this modification for the response of AML cells to chemotherapy and dissect the mechanism associated with this event. To translate these findings into the clinic we will test whether these patients are responsive to new agents targeting DNA methylation, and investigate survival of patients in a large independent cohort

Summary
The emergence of cancer is caused by multiple mutations in normal cells. Recent progress has allowed the detection of virtually all mutations in a cancer genome. Although this has been enormous progress, it has become increasingly evident that only rare mutations are responsible for sustained tumour growth and treatment failure, while the majority of mutations are without effect. Our research will assist identification of the genetic changes essential to leukemia development, which will help dev ....The emergence of cancer is caused by multiple mutations in normal cells.
