Summary
Stomach cancer is the third most prevalent cancer in the Western World and result in the yearly death of several thousand people in Australia alone. We have discovered a specifice gene mutation of a receptor molecule called gp130 that results in the formation of stomach cancer in mice. We are now aiming to understand the exact molecular events by which this mutation results in the uncontrolled growth of stomach mining cells.

We have discovered a specifice gene mutation of a receptor molecule called gp130 that results in the formation of stomach cancer in mice. We are now aiming to understand the exact molecular events by which this mutation results in the uncontrolled growth of stomach mining cells. Our proposal combines the expertise of the two investigators in signal transduction and the making of genetically modified mouse models. These strategies will be employed to specifically address in the laboratory mouse the function of two specififc signaling cascades, called Stat3 and TGF-beta. The identification of detailed description by which these molecules causally relate to cancer formation will provide clear and specific molecular targets for future therapies to treat various cancers, including those of the stomach.Read moreRead less

Summary
Tumor metastasis - the spread of tumor cells from the original site of growth to other sites in the body, is the biggest threat to survival for patients with solid tumors. The most damage change during cancer progression is the switch from a locally growing tumor to a metastastic killer. For biologist studying cancer, a major challenge is to identify the molecular and cellular mechanisms underlying the switch of non-invasive tumor to an invasive, metastatic state. This application aims to identi ....Tumor metastasis - the spread of tumor cells from the original site of growth to other sites in the body, is the biggest threat to survival for patients with solid tumors. The most damage change during cancer progression is the switch from a locally growing tumor to a metastastic killer. For biologist studying cancer, a major challenge is to identify the molecular and cellular mechanisms underlying the switch of non-invasive tumor to an invasive, metastatic state. This application aims to identify key molecular and cellular mechanism controlling this switch, with the ultimate aim being to devise treatments that inhibit tumor metastasis. The results from this work will provide clear and specific targets to prevent and to treat tumor metastasis. More importantly, the success of strategies used in this work can potentially be used clinically for tumor treatment.Read moreRead less

Summary
Fast growing tumors often outgrow the ability of blood vessels to properly supply them with nutrients and oxygen. This creates tissue areas within the tumor that are lacking oxygen and are highly resistant to radiotherapy and chemotherapy. Imaging these areas using nuclear medicine techniques has now become important for therapy planning of cancer sufferers. This project aims to improve the properties of the existing agents in order to better select patients for a particular type of treatment.
Breast cancer is a common disease that is generally incurable if detected after it has spread to other organs. There is a lack of understanding of molecular events that drive the process. Cancers contain several types of host cells that contribute to the growth of the tumour, which can be regarded as wounds that never heal. Host cells are co-opted to promote continued growth of the cancer cells. It is the aim of this project to understand how these host cells promote the spread of breast cancer

Summary
Of all cancers, liver cancer is the third biggest killer worldwide and there is currently no effective treatment options for this disease. We now know many of the common genetic changes that occur in liver tumour cells but have yet to develop targeted drug treatments. This project is aimed at determining whether reactivating a tumour cell's normal cancer suppressing functions can stop tumour growth and whether we can use this information to develop specific drugs that target liver tumour cells
