Funded Activity Summary

Colorectal and breast cancers are the two most common registrable cancers in Australia and are second only to lung cancer in the total number of cancer deaths each year (4,678 and 2,612 deaths in 1997 for colorectal and breast, respectively). Ovarian cancer kills a further 740 women each year (Source: Cancer in Australia 1997, AIHW and AACR 2000). Thus, on average, one Australian dies of colorectal, breast or ovarian cancer every hour! Clearly, these are major diseases with a significant impact on our society. Unfortunately, though, we still do not understand the basic molecular and-or biochemical abnormalities that initiate and-or drive the development of these cancers. Recent functional and genetic studies in a number of different tumour types (including colon and ovarian) have suggested that members of the phosphatidylinositol 3-kinase (PI3K) enzyme family may be oncogenes (cancer-causing genes). However, strong evidence confirming a causal role for PI3K in human cancer is yet to be reported. Our research proposal outlines a study to address this issue. We have preliminary data demonstrating mutations in at least one member of this enzyme family in a number of tumours. We now propose to undertake a comprehensive analysis of the spectrum, and frequency, of PI3K mutations that occur in colon, breast and ovarian tumours. These studies will allow us to make a definitive assessment of the role of PI3K in the development human cancer. In addition to furthering our understanding of the processes involved in the initiation and progression of human tumours, this project also has the potential to identify new markers for the early detection of cancer and novel targets for new anti-cancer therapies.
