Summary
There is growing evidence that cancer is initiated and develops not by the deregulation of a single gene or signaling pathway, but by multiple events. We will study the co-operation between two pathways - gp130-Stat and Wnt. These signaling pathways are frequently deregulated in many types of cancer, however their interaction remains poorly understood. We shall explore their mechanism of interaction during intestinal cancer in order to develop a novel therapeutic target for this disease.
The Intersection Between Hedgehog And Notch Signalling In Medulloblastoma.

Summary
Brain tumours are the second most common malignancy of childhood and the leading cause of cancer related death and disability in children. Medulloblastoma is the most frequent malignant childhood brain tumour, arising in the cerebellum. This application looks at the relationship between two genetic pathways responsible for medulloblastoma which are also drug targets. Understanding this interaction will lead to better treatment options for the disease.
Next-generation Sequencing Of Candidate Ovarian Tumour Suppressor Genes

Summary
In Australia in 2001 there were approximately 1300 new cases of ovarian cancer. Survival of ovarian cancer is very poor and current treatments inadequate. To develop more effective treatments we need to understand the molecular events that cause ovarian cancer. Some genes are inactivated by loss of a copy or mutation. We aim to find these genes using new DNA sequencing techniques.
Molecular Imaging As A Critical Tool In Discovery Of The Basis Of Tumour Heterogeneity And Developing Novel Therapies To Overcome Therapeutic Resistance

Summary
Determining treatment options for cancer currently relies on the size and extent of tumour deposits on imaging, combined with a biopsy. However, this approach fails to recognise the ability of tumours to evolve components that are, or become, resistant to treatment. My laboratory uses advanced molecular imaging, targeted biopsies, animal models and genetic analysis to detect and understand the basis of such resistance and thereby develop new, targeted treatments to improve patient outcomes.
Early Detection Of Melanoma Metastases Using MicroRNA As Novel Biomarkers

Funding Amount

Summary
The use of a minimally invasive blood test to measure the circulating levels of melanoma-specific miRNAs may provide a rapid assessment for clinical management of the disease during dissemination of the tumour. This work has the potential to provide new prognostic markers for melanoma as well as to identify new gene targets for the design of rational therapies to treat this disease.
HIC1 Prevents Tumour Initiation By Maintaining Genomic Stability

Summary
Chromosomes are large structures that package the genome. Abnormalities in the structure and function of chromosomes are now recognised an in important driver of cancer. Using a genetically engineered mouse model this project seeks to understand how this process evolves from the very earliest stages in the evolution of a tumour.
Tracking The Origins And Drivers Of Metastasis In Prostate Cancer

Summary
Prostate cancer is now the most commonly diagnosed cancer but only 10% of men with it, will die from it. Our current ability to discriminate between cancers with an indolent course and those that are lethal is poor. This project will examine the mixture of tumour clones (subclones) that are present in prostate cancers and define and track those cancer subclones that break away from the prostate and lodge in distant sites, causing death.
Ovarian cancer is frequently fatal and an extremely distressing cause of death in women. Our research program draws on the Australian Ovarian Cancer Study (AOCS), involving over 2000 women with ovarian cancer to investigate the genetic causes, and molecular changes that control cancer growth and response to therapy. The program is part of Australia’s $27m commitment to the International Cancer Genomics Consortium, an ambitious, worldwide effort to map the cancer genome.
Genomic Analysis Of The Novel Epigenetic Modifier Smchd1 As A Tumour Suppressor

Funding Amount
$619,142.00
Summary
Epigenetic modifications are changes made to our DNA that act like punctuation marks in the genome, to instruct the cell when to turn genes on and when to switch them off. Epigenetic control is critical to range of different biological processes, and also goes awry in cancer. We are specifically interested in the role of one new protein involved in epigentic control and characterising its role as a tumour suppressor.
Feasibility Of Implementing Precision Medicine For The Treatment Of Metastatic Melanoma

Funding Amount
$314,644.00
Summary
Melanoma is the most aggressive form of skin cancer, accounting for 75% of skin cancer deaths in Australia. When it progresses to stage IV disease, patient prognosis is poor, with less than 10% of cases surviving to 5 years. The goal of this project is to determine whether drugs currently used to treat different diseases could also be used to treat melanoma patients and improve their survival, particularly those that do not respond in current clinical trials.
