Summary
Squamous cell carcinoma of the head and neck is one of the six most frequent causes of cancer death worldwide. these tumours are currently treated with surgery, radiotherapy and chemotherapy. Although these treatments are associated with a five year survival rate of between 40% and 60% there is a critical need for more effective and less destructive treatments. In this application we will extend on our earlier work in which we identified the protein E2F1 as being a major contributor to tumour de ....Squamous cell carcinoma of the head and neck is one of the six most frequent causes of cancer death worldwide. these tumours are currently treated with surgery, radiotherapy and chemotherapy. Although these treatments are associated with a five year survival rate of between 40% and 60% there is a critical need for more effective and less destructive treatments. In this application we will extend on our earlier work in which we identified the protein E2F1 as being a major contributor to tumour development. In normal cells, E2F1 is required for the regulated growth of head and neck cells. However, we found that in head and neck tumours, E2F1 is overactive and contributes to the dergulated growth of the tumour. In this project we will test our newly developed inhibitors of E2F1 on various tumour cells derived from head and neck cancers to see how effective they are at stopping tumour cell growth. Furthermore we will test these compounds in animal models of head and neck cancer to determine whether they will be useful therapeutic agents for treatment of human cancer. Early results on tumour cell lines look very promising.Read moreRead less

Summary
Colorectal (or bowel) cancer is a major health problem in Australia. Approximately 1 in 21 Australians will develop the disease in his-her lifetime. The risk of bowel cancer increases with age, with the risk rising progressively and sharply from the age of 50. Current therapies for colorectal cancer are not very effective and the median survival for patients with this disease is poor at 7- 12 months. The development of colorectal cancer is complex and is affected by both genetic and environmenta ....Colorectal (or bowel) cancer is a major health problem in Australia. Approximately 1 in 21 Australians will develop the disease in his-her lifetime. The risk of bowel cancer increases with age, with the risk rising progressively and sharply from the age of 50. Current therapies for colorectal cancer are not very effective and the median survival for patients with this disease is poor at 7- 12 months. The development of colorectal cancer is complex and is affected by both genetic and environmental factors. Colorectal cancer progresses through a number of distinct pathological stages. This is thought to be the result of the progressive aquisition of mutations in genes that normally ensure a balance between cell growth and cell death. Mutations in a number of genes (known as APC, K-ras, p53, SMAD2, SMAD4) are commonly found in colorectal tumours. This research is aimed at understanding how genes which are altered in colon cancer influence the growth of cells in normal intestine. We have developed a system where normal mouse gut can be maintained and grown intact. Genes containing the alterations found in colon cancer will be introduced into the normal gut epithelial cells and the effects on the growth and behaviour of these cells analysed. This should improve our knowledge of how these altered genes contribute to the development of colon cancer.Read moreRead less
