EphA2 And EphA3 Maintain Tumour Initiating Cells And Are Therapeutic Targets In Brain Cancer

Summary
High-grade glioma (HGG) is the most common adult brain cancer; current treatments have increased survival times by months only. Our studies have shown brain cancer specific expression of a family of cell surface proteins called Eph receptors. Furthermore we have shown targeting these receptors with Eph antibodies leads to a significant reduction in brain cancer tumour growth. We now propose to test targeting these receptors in combination to achieve greater responses with minimal side effects.
Contribution Of MDSC-derived Cysteine Cathepsins In Breast Cancer Metastasis To Bone

Summary
Cathepsins are enzymes called proteases that function to cleave specific proteins, a process that is important for many normal cellular functions. Aberrant cathepsin activity can result in a number of pathologies, including cancer and inflammation. We are developing tools called activity-based probes to study the function of cathepsins in disease. Specifically, we will investigate their activity within cells of the immune system with the goal of developing novel therapeutic approaches.
Inhibiting Tumour Growth By Targeting EphA3 And Disrupting Tumour Stromal And Vascular Microenvironment

Funding Amount
$645,136.00
Summary
Tumours consist of cancer cells, tumour blood vessels and connective tissue, all of which are different to normal tissues. Many of the cells making up tumour vessels and connective tissue are recruited, during initial growth and subsequent spreading of tumours, from the bone marrow. Our research will examine the presence and function of the EphA3 receptor on these cells during tumour development and assess how our anti-EphA3 antibody inhibits tumour growth by targeting stroma and vasculature.
A Novel Approach To Restoration Of Tumour Suppression In Lung Cancer

Funding Amount
$598,604.00
Summary
Loss of a tumour suppressor is a key event in every cancer, including lung cancer. Therefore restoration of the expression and/or activity of the tumour suppressor is an attractive approach to anti-cancer treatment. In order to restore tumour suppression, a detailed understanding of the mechanism by which a given tumour suppressor is regulated is required. This application focuses on our discovery of a novel mechanism by which a key tumour suppressor of lung cancer is regulated.
Immunotherapy has recently shown promise in bone cancer. We have found that while immune modulators Il-6 and Ifn?? contribute to tumour suppression Il-23 promotes the growth of radiation-induced bone cancer. We have generated mouse models of bone cancer to investigate tumour growth and immune surveillance in immune competent mice with an overall aim of identifying therapeutic targets in this disease.
Identification Of The Molecular Hallmarks Of Naevi Progressing To Melanoma

Funding Amount
$314,644.00
Summary
Melanomas are amongst the most commonly occurring cancers in Australia with >136,000 people living with a previous melanoma diagnosis. One of the highest risk factors for developing melanoma is having a high number of moles (or naevi). It is therefore important to fully understand how and why naevi develop into melanoma. It is hoped that early detection markers will be identified which will help identify early melanomas and as such improve patient outcome.
FOXP3 Regulated MicroRNAs: A Novel Component Of FOXP3 Tumour Suppressor Function In Breast Epithelial Cells.

Funding Amount
$554,716.00
Summary
Until there is a cure, breast cancer research must continue to discover new targets for therapy. We have novel insight into a new tumour supressor; FOXP3, and have identified the genes it regulates in T cells. We can now apply this information to normal breast tissues to reveal the mechanism and targets that FOXP3 controls to prevent cancer
Nuclear Receptors And Triple Negative Breast Cancer

Funding Amount
$681,979.00
Summary
This project will explore the potential for a nuclear receptor known as the thyroid receptor to suppress growth of breast cancer using cell culture models and mouse models. We hope to show that activating the thyroid receptors leads to a reduction in breast cancer growth providing evidence that the thyroid receptor pathway could be targeted for therapy.
Targeting Microtubules To Overcome Chemoresistance In Pancreatic Cancer

Funding Amount
$594,336.00
Summary
Pancreatic cancer is a devastating disease with a dismal prognosis because it is extremely resistant to chemotherapy agents. We plan to examine the expression of proteins called microtubules in pancreatic cancer and assess their role in drug resistance. It is anticipated that the findings of these studies will lead to the development of effective approaches to sensitise the cancer cells to chemotherapy agents.
Determining The Tumour Suppressor Function Of The MCC Gene And Its Significance To Treatment Outcomes In Colorectal Cancer.

Funding Amount
$620,716.00
Summary
This project analyses the early stages of bowel cancer, where we have discovered a new gene defect. We want to determine how the MCC gene defect promotes tumorigenesis and how it affects treatment outcomes, by studying a novel mouse model of bowel cancer. This will determine which cellular functions are altered following loss of MCC in bowel tumours and if the MCC defect can be exploited to identify patients who would benefit from radiotherapy or specific chemotherapies.
