Cancers we study: • Colorectal cancer (CRC) • Leukaemia • Melanoma • Glioblastoma (GBM)
Anti-cancer drugs • Identification of proteome changes in cancer cells after treatment with a drug such as: • Purine analogues (e.g., fludarabine) • HSP90 inhibitors (e.g., SNX-7081) • ER-stress inducers (e.g., thapsigargin) • Understand mechanisms of drug action and resistance, identification of new drug targets
Cell surface markers • DotScan™ CD antibody microarrays • Capture live cells and obtain a surface profile (disease signature, immunophenotype) • In collaboration with major NSW hospitals, we have collected and tested many different clinical samples, including: • Leukaemias • Colorectal cancers • Metastatic melanoma • To improve disease stratification, prognostication and prediction of response to treatment
Comprehensive, quantitative clinical proteomics • Stage III melanoma Survival analyses – prognostic biomarkers good versus poor prognosis groups with identical stage cancers • Glioblastoma multiforme Serial lesions, pre and post chemotherapy, biomarkers for chemo-resistance • Chronic lymphocytic Leukaemia Stable vsprogressive disease course
Techniques • Clinical samples and cell lines • In vitro chemotherapy treatment • Flow cytometry • Sub-cellular proteome isolation • Cytosol, nucleus, mitochondria and plasma membrane • Mass Spectrometry and gel-based analyses (SUPRU) • Quantitative analysis • DIGE, iTRAQ, SRM and label-free methods
