Cancer is the result of multiple genetic errors, involving both the overactivity of growth-stimulating oncogenes and the loss of tumour suppressor genes. The identification of the genes in both of these categories is important if we are to understand and intervene in the disease. Tumour suppressors are the more difficult to identify, precisely because they are lost in cancer cells. Normally the task is extremely time consuming, tedious and expensive.

The identification of the genes in both of these categories is important if we are to understand and intervene in the disease. Tumour suppressors are the more difficult to identify, precisely because they are lost in cancer cells. Normally the task is extremely time consuming, tedious and expensive. We have developed a system which will provide a short-cut to the cloning of one such gene. We have started with the mouse version, which is lost in leukemic cells. We have mapped the gene to within a very small chromosomal region, and we have identified a biological effect which correlates with loss of the gene. Our next step is to combine these two approaches to clone the gene. Because these genes are always highly conserved between species, we will be able to quickly clone the corresponding human gene, the loss of which is very likely to be important in cancer of various types.Read moreRead less
Genomic Analysis Of The Novel Epigenetic Modifier Smchd1 As A Tumour Suppressor

Summary
Epigenetic modifications are changes made to our DNA that act like punctuation marks in the genome, to instruct the cell when to turn genes on and when to switch them off. Epigenetic control is critical to range of different biological processes, and also goes awry in cancer. We are specifically interested in the role of one new protein involved in epigentic control and characterising its role as a tumour suppressor.
The Importance Of RUNX3 In Preventing Gastrointestinal Diseases And Tumour Metastasis

Summary
Stomach cancer is the second leading cause of cancer-related deaths. It is estimated that in 2010, more than 1 million people will die of stomach cancer with an increase of 19%. Studies have revealed that RUNX3 has the ability to suppress the growth of stomach cancer. However the role of RUNX3 in preventing metastasis is yet unknown. Therefore, an understanding of the factors that govern metastasis will inform the design of effective therapies to prevent mortality which is high for this disease.
The Molecular Function And Role Of The New Metastasis Suppressor NDRG1 In Cancer

Summary
With cancer now a leading cause of death in Australia, finding new ways to treat this disease is crucial. Iron is critical for cancer cell growth and metastasis, thus agents that bind iron (called iron chelators) can be used to treat cancer. These drugs up-regulate the gene NDRG1, which has been shown to prevent tumour spread. The role of NDRG1 in tumour growth and spread of cancer cells will be examined as this may lead to novel therapies against cancer (e.g. the use of novel iron chelators).
FOXP3 Regulated MicroRNAs: A Novel Component Of FOXP3 Tumour Suppressor Function In Breast Epithelial Cells.

Summary
Until there is a cure, breast cancer research must continue to discover new targets for therapy. We have novel insight into a new tumour supressor; FOXP3, and have identified the genes it regulates in T cells. We can now apply this information to normal breast tissues to reveal the mechanism and targets that FOXP3 controls to prevent cancer
