About the research project

The vast majority of deaths associated with solid tumours are due to metastatic disease. Aggressive prostate cancers (PrCa) are particularly problematic as these tumours have a high propensity to metastasise to bone. Five-year survival for men with bone metastatic PrCa lesions is ~6%, and current therapies available are both limited and largely ineffective. Lethality-based genome-wide (CRISPR/Cas9) screens are an innovative technique used to uncover the genes that underpin complex disease, the outcomes of which are seeding important advances particularly for cancer treatment. We have performed a successful lethality-based genome-wide screen in an aggressive prostate cancer cell line (isolated from a patient with bone metastases) and identified several mitochondrial-associated genes as the top ranked genes driving survival and metastatic behaviour. Mitochondria, as the cell's powerhouse, are known to sustain tumour cell proliferation and survival, and this project seeks to uncover how these genes are critical to the metastatic cell state in PrCa, and further how this knowledge can be harnessed to develop much needed therapeutic interventions for metastatic disease. Our close clinical collaboration with both public and private prostate cancer treatment service providers has enabled us to develop a rare clinically annotated biospecimen resource comprising matched primary and metastatic tumour specimen.

In this project, we will explore the functionality of the identified genes and their role in influencing cell proliferation, migration, and mitochondrial functional assays in vitro, in addition to their influence on metastasis in a xenograft zebrafish model. Further, we will utilise our existing extensive clinically annotated prostate tumour pathology resources to explore association of these genes with clinicopathological features of PrCa. A second focus of our work will be to explore the influence of these genes on sensitivity to current radiotherapeutic and chemotherapeutic interventions and their putative value as prognostic indicators of therapeutic response, and or as therapeutic targets for drug intervention.
