Hollande laboratory: Tumour Heterogeneity in Metastatic Cancer
+61 3 9035 8780
Associate Professor Fred Hollande's research group aims to understand mechanisms that underlie the genetic and non-genetic heterogeneity within individual tumours, and to characterise signalling pathways that specify the differential behaviour of cell subpopulations that drive metastatic progression and treatment response. We are interested to determine the respective contributions of intrinsic programs and of extrinsic/micro-environmental cues in the control of these signalling events.
The group also aims to characterise the molecular mechanisms that underlie the phenotypic plasticity of cancer cells and to understand how this plasticity affects the response of tumour-initiating cells to anti-cancer treatments.
Our interest is in solid tumours with a primary focus on colorectal cancer, a major public health issue and one of the main causes of cancer-related death in Australia and worldwide.
Translational objectives of our work include the discovery of novel biomarkers providing early prognosis and prediction of treatment response, and the improvement of therapeutic efficacy by targeting cells that drive disease relapse after therapy. This is achieved by combining the phenotypic and genotypic analysis of samples freshly obtained from cancer patients and by characterising molecular networks that drive drug resistance in subpopulations of cancer cells.
Benefiting from the collaborative efforts of surgeons, medical oncologists, genomics specialists, statisticians and systems biologists from several VCCC member organisations, this project uses an innovative approach to characterise and target these drug-resistant cancer cell subpopulations.
To do so, Associate Professor Hollande's lab has developed ex vivo models that allow the unbiased analysis of differential responses to drug treatment by individual subpopulations of cancer cells within individual tumours. This will allow the identification of pathways that drive the intrinsic drug-resistance ability of specific cancer cell subpopulations and/or the plasticity behaviours that allow them to adapt and survive during treatment exposure. Preclinical orthotopic graft models are then used to validate the sensitivity of these newly identified targets to pharmacological inhibition.
A broad array of experimental models is used in the team, including 2D and 3D tissue culture, ex vivo analysis of human metastatic tumour samples, live and static cell imaging, flow cytometry, cytotoxicity assays, methylation analysis, genome-wide RNA analysis, and various xenograft models.
