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.

Summary
Prostate cancer (PCa) claims the lives of over 3,000 Australian men each year. This highlights the urgent need to identify new molecular targets that can be developed as additional therapies for men with PCa. Our team has identified the protein, Zeb1, to be highly expressed in aggressive and treatment resistant forms of PCa. This study aims to characterise the role of Zeb1 in the lethal progression of PCa and to develop a new therapeutic agent to inhibit the production of ZEB1 by cancer cells.
Prostate cancer is the most common cancer in men, causing about 3,300 deaths per year. We have identified some small RNAs called microRNAs and other hormone regulators that can interfere with prostate cancer cell growth and signaling via the testosterone pathway. In this application we will be exploring the potential for each of these agents to reduce prostate cancer growth and the possibility that one or more could develop into a therapeutic target in the future.
Targeting MicroRNA-driven Mesenchymal To Epithelial Transition To Suppress Prostate Cancer Metastasis

Summary
Prostate cancer kills ~3,000 men per year in Australia. The development of metastasis is the major cause of prostate cancer-associated death and has limited treatment options. In this study, we will characterise the role of a group of molecules, termed microRNAs, in prostate cancer metastasis. We will also test whether targeting microRNAs using novel drugs termed antagomiRs is an effective strategy to inhibit metastasis and thereby improve prostate cancer mortality.
Identification Of PACE-1 As A Novel Therapeutic Target For The Treatment Of Prostate Cancer

Summary
Advanced prostate cancer (PCa) remains the major therapeutic challenge since neither surgery nor systemic therapies are effective at this stage. Recently, we identified a protein called PACE-1 that is essential for PCa cell survival. We plan to investigate the roles of PACE-1 in the development and progression of prostate cancer. We will then test if PACE-1 inactivation alone or in combination with systemic cancer therapies will inhibit prostate tumor growth and disease progression.
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.
Delineating Mechanisms Of Acquired Resistance To Kinase Inhibitors And Devising Novel Strategies To Combat Therapeutic Resistance

Summary
Kinase inhibitors are some of the most successful anti-cancer agents that have emerged in the last 15 years. However, tumors become resistant to these drugs after showing initial response. Understanding mechanisms through which cancer cells become resistant to these drugs will allow us to develop effective strategies to counter it and achieve sustained responses to cancer therapy. I propose to build a research program to systematically study these mechanisms to improve cancer therapeutics.
Clinicopathological Characterisation Of Male Breast Cancer

Summary
Male Breast Cancer is an uncommon and poorly understood disease. Due to its low frequency, there is a paucity of studies with large numbers of patients. Our aim will be to establish one of the largest worldwide databases of Male Breast Cancer. This will allow us to more thoroughly investigate clinical, pathological and molecular characteristics of male breast cancer, improve treatment of these patients and potentially develop novel and innovative strategies for treatment of female breast cancer.
Companion Biomarker And Therapeutic Strategy Development For Pancreatic Cancer

Summary
Innovation of predictive and responsive biomarkers in pancreatic cancer (PC) is of paramount importance. This project contains two parts: 1. Circulating DNA. It has been shown previously that DNA released into the blood stream by cancer can be measured, its usefulness in PC will be assessed. 2. ROCK-I as a predictive biomarker. ROCK-I is a protein involved in cell motility. The ability for ROCK-I amplification to predict for response to ROCK-I inhibitors will be assessed in vitro/in vivo.
Toll-like Receptor 2 Signalling As A Potential Therapeutic Target In Gastric Cancer

Summary
Stomach cancer is the fourth most deadly cancer in the world. Stomach cancer is closely linked with inflammation, and we have shown that a key inflammatory molecule, called toll-like receptor 2 (TLR2), can drive the development of stomach cancer. However, this occurs in a non-inflammatory manner. My research aims to understand how TLR2 is involved in the progression of stomach cancer, with the ultimate goal to find an early biomarker of disease, and to develop better therapies.
