Summary
A high level of MYCN protein is a major indicator of aggressive neuroblastoma (NB) but unfortunately there have been many barriers to the design of targeted therapies. We have identified a protein called PA2G4 which is a cofactor for MYCN in promoting cancer cell growth. We have developed a compound which inhibits PA2G4 and MYCN protein levels and reduces tumour growth. We will examine how PA2G4 cause aggressive tumour characteristics and test new methods to block PA2G4.
Towards Better Treatments For Acral Melanoma Through Functional Genomics

Summary
Acral melanoma is an uncommon melanoma subtype with bad prognosis that has been poorly characterised at the molecular level. The project will conduct comprehensive analysis of acral melanoma at the DNA, RNA and protein levels. Through subsequent functional follow-up studies of key drivers of this cancer type we will identify novel drug targets to treat this disease.
Optimising Targeted Polyamine Depletion For Treatment Of Childhood Neuroblastoma And Brain Tumours

Summary
Paediatric neuroblastoma and brain tumours, which often have dismal outcomes despite intensive therapy, have high levels of polyamines, which are essential for cell growth. We have shown that depleting polyamines, combined with chemotherapy, represents a highly promising therapy for neuroblastoma. We will make this exciting new treatment approach even more effective by comparing three ways of enhancing polyamine depletion, as a precursor to future neuroblastoma and brain tumour clinical trials.
The FGFR Family As Drivers And Biomarkers Of Regorafenib Response In Gastric Cancer.

Summary
The drug regorafenib has recently emerged as a potential new treatment for patients with gastric (stomach) cancer. We have discovered that gastric cancer cell lines which express high levels of members of the FGFR family are highly sensitive to this drug. This project will define the potential of targeting the FGFR family in gastric cancer,the value of FGFR1-4 as markers of regorafenib response, and develop strategies for enhancing regorafenib activity in this difficult to treat disease.
Targeted Inhibition Of Multidrug Resistance-associated Protein 4 (MRP4) As A Therapeutic Strategy For Childhood Neuroblastoma

Funding Amount
$602,503.00
Summary
We have shown that a high tumour level of the gene, MRP4, confers a particularly poor outcome in children with the aggressive cancer neuroblastoma. Our results suggest that MRP4 can drive the growth of neuroblastoma cells, and that it does so by removing from the cancer cell a compound that normally regulates key cellular responses including survival and differentiation. We will explore this, and will also test promising inhibitors of MRP4 with therapeutic potential, that we have developed.
Targeting A Master Regulator Of Tumour Cell Plasticity As A New Adjuvant Therapy For Prostate Cancer

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.
Osteosarcoma is the most common tumour of bone. Recent success in targeting immune checkpoint blockers such as Programmed death-1 (PD-1) in genomically complex tumours suggests that osteosarcomas may be amenable to such strategies. We will characterise the role of the PD-1 pathway in osteosarcoma development and growth. Using preclinical mouse models we will investigate the biology of the PD-1 pathway and study its potential as a therapeutic target in advanced and resectable osteosarcoma.
BRCA-P: An International Randomised Phase III Study Evaluating The RANK Ligand Inhibitor Denosumab For The Prevention Of Breast Cancer In BRCA1 Mutation Carriers

Summary
Women with a faulty BRCA1 gene are at high lifetime risk for breast cancer. Identifying a safe and effective prevention therapy is therefore a ‘holy grail’. We have discovered that denosumab, used to treat osteoporosis or breast cancer spread to bone, could be ‘repurposed’ as a prevention drug. BRCA-P is an international randomised controlled study that will determine if denosumab prevents breast cancer. Associated translational research will facilitate swift transfer to the clinic.
Identification Of PACE-1 As A Novel Therapeutic Target For The Treatment Of Prostate Cancer

Funding Amount

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.
Antibody-based Inhibition Of ADAM10 As Cancer Immunotherapy

Funding Amount
$652,788.00
Summary
Despite our advances in understanding the molecular basis of cancer, treatments for metastatic cancers are limited, emphasising an urgent need for strategies targeting several oncogenic pathways. We generated monoclonal antibodies effectively blocking the activity of ADAM10, an oncogenic cell surface protease that activates tumour growth, invasion and metastasis through multiple pathways. Here we describe the strategies that progress these antibodies as lead therapeutics for clinical testing.
