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.
Toward Effective Targeted Therapies For Acute Myeloid Leukaemia (AML)

Summary
Standard chemotherapy for acute myeloid leukaemia (AML) is highly toxic, and has not changed in over 40 years. We will conduct a world-first clinical trial incorporating ABT-199 (Venetoclax) to target BCL2 into the standard-of-care treatment for AML. A second initiative will explore the potential for small molecule inhibitors to simultaneously target both BCL2 and its related partner MCL1, to create a “chemotherapy-free” regimen for AML. These studies promise to herald a new era in AML therapy.
The Mutagenic Influence Of 5-methylcytosine And Its Relevance For Cancer Treatment

Summary
Over time our cells accumulate damage to their DNA, which introduces mistakes in the genetic code. These mistakes can alter genes that regulate cell growth and survival and, in this way, they begin the process of turning a normal cell into a cancer. This research is investigating the cellular repair mechanisms that safeguard against DNA damage. Manipulating these repair mechanisms may offer a new way to treat cancer, by selectively inducing DNA damage within cancer cells.
The Clinical Value Of Serology And Molecular Tests For Diagnosing Invasive Aspergillosis In At-risk Hematology Patients

Summary
Aspergillus is a fungus found in soil, on farms and on construction sites. In those whose immune system is impaired it causes severe infection. The people who are particularly at high-risk of Aspergillus infection (called Invasive Aspergillosis) are those with acute leukaemia on chemotherapy or post bone marrow transplantation. Currently 15% of those at high-risk get Invasive Aspergillosis and 58-93% of those infected die. The main reason for this high death rate is that our current diagnostic t ....Aspergillus is a fungus found in soil, on farms and on construction sites. In those whose immune system is impaired it causes severe infection. The people who are particularly at high-risk of Aspergillus infection (called Invasive Aspergillosis) are those with acute leukaemia on chemotherapy or post bone marrow transplantation. Currently 15% of those at high-risk get Invasive Aspergillosis and 58-93% of those infected die. The main reason for this high death rate is that our current diagnostic tests are not good at detecting infection or often only detect the infection at advanced stages when treatment is ineffective. Because of the limitations of current diagnostic tests the current practice is to give empiric antifungal therapy (EAFT) early to treat Invasive Aspergillosis. However studies have demonstrated that this therapy has only resulted in a minor reduction in the mortality rates and it causes significant drug toxicity. It is a suboptimal treatment modality. New tests have been developed to diagnose Invasive Aspergillosis. These tests are for the detection of an Aspergillus protein in blood and for the detection of Aspergillus DNA in the blood. Available data suggests that these new tests are sensitive in the detection of Invasive Aspergillosis. Also other studies suggest that these new tests make an early diagnosis and seem to be able to monitor responses to treatment. However no study has been performed to date which demonstrates that the use of these tests can impact on important patient outcomes. This trial is designed to determine whether the use of the new tests to guide therapy will help improve treatment of Invasive Aspergillosis, reduce drug toxicity and reduce the death rate in the high-risk patients as compared with the current standard method of diagnosis and treatment with EAFT. If the trial is successful then this represents a significant advancement in the treatment and survival of leukaemic and bone marrow transplantation patients.Read moreRead less
Mechanisms Of Glucocorticoid Resistance In Acute Lymphoblastic Leukaemia

Funding Amount
$547,970.00
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.
Improving Outcomes For Cancer Patients By Targeting The Epigenome

Funding Amount
$2,258,892.00
Summary
The most commonly mutated proteins in cancer involve so called epigenetic regulators, a class of proteins that regulate access to our DNA to control gene expression, DNA repair and replication. We and others have recently developed a variety of drugs to help inhibit the aberrant activity of these epigenetic proteins. My research will focus on ways to improve the efficacy of these existing drugs and find new epigenetic therapies to improve the survival of patients with a broad range of cancers.
Learning The Mechanisms Of Programmed Cell Death And Tumour Suppression To Develop Novel Cancer Therapies

Funding Amount
$863,910.00
Summary
Our bodies prevent the development of cancer through tumour suppressive processes, which also affect the outcome of cancer therapy. Programmed cell death (apoptosis) is one such process, and defects in apoptosis promote cancer development and impair the response of tumour cells to anti-cancer therapies. My laboratory uses molecular biology and cell biology approaches to investigate the mechanisms of cell death and tumour suppression, partnering with pharma to develop novel cancer therapies.
Epigenetic Therapies As Molecular Probes To Investigate The Molecular Pathogenesis Of Leukaemia

Funding Amount
$937,402.00
Summary
A major limitation to the success of targeted therapies in cancer is the fact that we have few if any tools to study in detail their mechanism of action within cancerous and normal cells. If we were able to visualise these drugs within cells and precisely characterise the proteins, DNA and RNA within a cell that interact with these therapies we will be able to identify strategies that can optimise their efficacy and reduce the side-effects of these treatments.
Unlocking Hidden Cancer Drivers Using Transcriptome Data

Funding Amount
$700,473.00
Summary
New sequencing technologies allow us to get an unbiased look at the molecular signalling in a tumour. However this information is very complex and need specialised methods in statistic and computation in order to make new discoveries. Here will will develop analysis methods to find novel transcriptional variants in cancer and then test them in the lab in order to understand if our discoveries are responsible for causing cancer.
Circulating Tumour DNA To Monitor Treatment Response And Resistance In Chronic Lymphocytic Leukaemia

Funding Amount
$876,950.00
Summary
Many cancers shed small amounts of DNA (ctDNA) into the patient’s bloodstream and recent advances in genomic technologies now allow levels of ctDNA to be accurately measured in the blood. Changes in ctDNA levels have potential to be used as specific markers of disease progression and/or response to cancer therapy. This project will evaluate if ctDNA can be used to monitor treatment responses and individualise treatment decisions in patients with chronic lymphocytic leukaemia.
