The Translational Research laboratory fosters collaboration between laboratory research and clinical areas of Peter Mac though investigating the application of new targeted therapies for cancer by integrating cell biology, molecular biology, functional imaging and clinical trials.
PhD IN CANCER: targeting early metastatic disease
Do you have a postgraduate qualification in clinical medicine or other clinical disciplines related to cancer?
A unique opportunity exists to undertake a PhD as part of Australia’s largest cancer group in collaboration with the CRC for Cancer Therapeutics.For more information download the PhD in Cancer flyer.
The Biomarkers team focuses on identifying predictive and prognostic biomarkers in lung cancer, head and neck cancer and melanoma. The research team performs translational research to identify robust biomarkers that predict response to therapy, correlating these with disease outcome in patients. This major focus on new biomarkers to predict treatment response will enable better selection of patients for appropriate therapies. Using human tissue samples sourced from clinical trials and archives, researchers focus on identifying and then validating biomarkers in lung cancer, head and neck cancer and melanoma, using a range of techniques, including immunohistochemistry, in-situ hybridisation, enzyme-linked immunosorbent assay (ELISA) and polymerase chain reaction (PCR).
Specific projects include:
Investigating prognostic and predictive biomarkers of hypoxia in head and neck squamous cell cancer
Investigating biomarkers of human papilloma virus infection in tonsil cancer and their relationship to patient outcomes
Investigating circulating tumour cells and circulating tumour DNA as prognostic and predictive biomarkers in melanoma, and to track longitudinal genomic changes during treatment.
The Developmental Therapeutics team performs pre-clinical evaluation of novel compounds for activity as anti-cancer drugs. The team, led by Dr Carleen Cullinane, interacts with academia and the biotechnology and pharmaceutical sectors in utilising a wide range of in vitro and in vivo assays for the evaluation of novel compounds for anti-tumour activity. In vitro assessments include cell proliferation and clonogenic survival assays; in vivoassays include dose finding studies, human tumour xenografts, mouse syngeneic models, and single agent or combination studies with chemotherapy, immunotherapy or radiation therapy. The basis of tumour response is also evaluated using tissue biomarker analyses. Non-invasive PET imaging is performed in collaboration with the Molecular Imaging and Targeted Therapeutics laboratory to identify imaging biomarkers of tumour response to novel targeted therapies. In complementary studies, whole body autoradiography together with high resolution micro-autoradiography is then used to define the biodistribution of radiolabelled compounds in vivo.
Specific activities include:
Using in vitro assays and in vivo mouse models for pre-clinical drug evaluation
Developing in vitro and in vivo models pertinent to the evaluation of novel anti-cancer drugs
Using PET imaging for assessment of tumour response to novel targeted therapies
Interaction with academic laboratories, biotechnology companies and the pharmaceutical industry.
Translational Cancer Biology
The CRC for Cancer Therapeutics Translational Cancer Biology team contributes to the development of new small molecule targeted therapies for cancer by integrating cell biology, molecular biology and pre-clinical small animal imaging. The research group focuses on three main lines of investigation: developing specific strategies to assess cell-based potency of small molecule drug candidates, developing pharmacodynamic and predictive biomarkers of response to novel therapeutics and selecting in vivo models of cancer to provide proof-of-concept efficacy data with particular focus on the use of non-invasive imaging technologies. Through this research, the team contributes to the assembly of a data-rich pre-clinical compound brochure as a forerunner to compound licensing for late-stage pre-clinical and clinical assessment. The research team, led by Dr Mark Devlin, works together with other CRC for Cancer Therapeutics research groups and a broad array of enabling technologies to interrogate these processes, including human xenograft and mouse syngeneic tumour models, genetic modification of cancer cell lines, in vivo imaging using fluorescence and bioluminescence modalities, microscopy, immunohistochemistry and quantitative protein analyses.
Specific activities include:
Developing and testing of small molecule inhibitors of novel cancer targets
Identifying and validating biomarkers to predict response to targeted therapeutics
Understanding the mechanisms of action of therapeutics targeting signalling, cell cycle and cell surface receptors.
