Funded Activity Summary

The induction of apoptosis, or programmed cell death, is a key factor in the response of tumours to chemotherapeutic agents and ionising radiation; therefore biological markers that predict the clinical outcome to these therapies are needed. Over the past 2 years, our laboratory has developed techniques of protein analysis to evaluate changes in proteins during apoptosis caused by chemotherapeutic agents. Preliminary protein profiling studies of apoptosis induction in human breast cancer cell lines showed time-dependent decreases in two proteins, identified as S100A6 and ubiquitin. Both are known to be important in cell function. In the proposed project we will build on our preliminary findings to provide important new information central to the understanding of cancer cell biology and apoptosis in addition to evaluating the ability of anti-cancer treatments to induce apoptosis. Using a combination of protein analysis technologies, this project has the potential to provide reliable and novel biomarkers which will indicate the efficacy and selectivity of anti-cancer treatments in inducing tumour cell death. The knowledge gained in this project will aid clinical assessment of the response to cancer treatment(s) in patients in the form of specific screening assays, and may result in identification and development of effective new agents for cancer treatment and prevention. Furthermore, the outcomes of this project will increase our understanding of fundamental cancer cell biology and apoptosis.
