The Microniche: A Novel In-vitro And In-vivo Prostate Cancer Model System

Summary
Maintaining primary prostate cancer cells (PCa) in vitro remains an enormous challenge for the field, and this obstructs efforts to systematically characterize cell behaviour and quantify drug response. Our group recently developed a 3-demsensional (3D) organoid culture system that does maintain PCa in vitro, and here we will integrate this technology with our 3D bone maorrow niche model system to better characterize PCa bone metastases and identify new clinical treatment regimes.
Identifying Castrate-resistant Tumour Cells In Localised Prostate Cancer

Funding Amount
$573,047.00
Summary
This proposal addresses one of the most important challenges in cancer: what cell population ‘drives’ tumour progression, and how can it be effectively targeted? We will define the prostate cancer cells that survive androgen withdrawal therapy and investigate new ways to target them. Eliminating these important cells earlier in disease progression will lead to increased survival for men with prostate cancer.
Novel Targeting Of Therapy-resistant Prostate Cancer Cells.

Summary
Prostate cancer is treated by removing male hormones (androgens). Although the bulk of the tumour regresses, some cells remain and the cancer often grows back in an aggressive form. We will study new ways to eliminate therapy resistant cancer cells and thereby provide more lasting treatments for prostate cancer. Ultimately, we hope to inform the design of ground-breaking clinical trials that could re-shape the treatment paradigm of advanced prostate cancer.
Each year, 18,000 Australian men are diagnosed with prostate cancer. While current treatments are designed to directly target cancer cells, the tumour-associated stroma is also recognised to play a pivotal in the establishment and progression of prostate cancer. This grant aims to investigate the contribution of stromal Hedgehog signalling, with the view to creating new treatment strategies that will treat the entire tumor environment.
Endosomal Reactive Oxygen Species In Tumour Angiogenesis

Summary
Cancer claims more lives worldwide than any other disease affecting millions of people annually. Tumours grow and spread in the body by acquiring their own blood vessels that provide them with nutrients and oxygen. We have identified a new protein called NADPH oxidase that promotes the development of these new blood vessels in tumours. We propose to test new drugs that block NADPH oxidase activity to stop the development of new blood vessels for the potential treatment of cancer
Dual Targeting Of The Androgen Receptor For Effective And Durable Control Of Lethal Prostate Cancer

Summary
Preventing binding of androgens to the androgen receptor is the mainstay treatment for advanced prostate cancer, but resistance inevitably develops and the disease becomes lethal. We will develop a new drug that targets a part of the androgen receptor unrelated to its androgen binding function to overcome resistance to current therapy. As this drug will be effective in all stages of prostate cancer, it has high potential to improve survival outcomes for men with prostate cancer.
KLK4 Is A Master Regulator Of Tumour Microenvironment Remodelling In Prostate Cancer And Bone Metastasis

Funding Amount
$596,305.00
Summary
The current biomarker for prostate cancer, PSA, belongs to a large family of related proteins called KLK enzymes. We have evidence that one of these enzymes, KLK4, regulates many different pathways involved in tumour spreading especially to bones. This project will determine the specific components involved with a view to finding better biomarkers of tumour spread and bone metastasis and designing better treatments for these aspects of the disease.
