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
Anti-cancer drugs

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
Cell surface markers

Stage III melanoma Survival analyses – prognostic biomarkers good versus poor prognosis groups with
identical stage cancers
Glioblastoma multiformeSerial lesions, pre and post chemotherapy, biomarkers for chemo-resistance
Chronic lymphocytic LeukaemiaStable vs progressive disease course
Comprehensive, quantitative clinical proteomics
