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).

Summary
c-myb is essential for the normal biology of the blood system and the colon. It is involved in regulating the balance between the production of new cells and their timely removal once they have completed their assigned tasks. Another group of factors that make up theWnt pathway also contribute to the normal biology of the colon in man and mouse. Defects that lead to too much c-myb and ineffective control of the Wnt pathway appear to work together to increase the risk and severity of colon cancer ....c-myb is essential for the normal biology of the blood system and the colon. It is involved in regulating the balance between the production of new cells and their timely removal once they have completed their assigned tasks. Another group of factors that make up theWnt pathway also contribute to the normal biology of the colon in man and mouse. Defects that lead to too much c-myb and ineffective control of the Wnt pathway appear to work together to increase the risk and severity of colon cancer. This project is designed to specifically test this observation in animals. In addition it examines in fine detail how c-myb levels increase in colon cancer and how it combines with the Wnt pathway to regulate other genes in colon cancer.Read moreRead less

Summary
Breast cancer is the most common cancer to affect women, with one in 10 developing the disease. Although treatment of breast cancer has substantially improved over the last few years, 25% of women diagnosed with this cancer will die from the disease. A major objective of cancer research is the identification of genes involved in tumour development and definition of their precise role in both normal and cancer cells.

Although treatment of breast cancer has substantially improved over the last few years, 25% of women diagnosed with this cancer will die from the disease. A major objective of cancer research is the identification of genes involved in tumour development and definition of their precise role in both normal and cancer cells. The design of effective therapeutic inhibitors of cancer requires an understanding of the basic molecular and cellular biology behind the genetic changes thought to contribute to cancer. The focus of our research is to understand normal cellular mechanisms that drive growth and differentiation of breast tissue, and those changes that lead to breast cancer. Nuclear regulatory proteins have been implicated in many different types of cancers and leukaemias. We aim to identify the key regulators in breast tissue, characterising both their structural properties and biological roles, with the ultimate view of understanding how they divert a normal cell to a cancerous cell. This proposal centres on the characterisation of a specific regulatory molecule which we recently demonstrated to be overexpressed in 56% of human primary breast cancers and in 38% of pre-invasive ductal carcinoma in situ. These studies will include defining its normal biologic function and identification of the proteins that this regulator associates with in breast cancer cells.Read moreRead less
Identification And Functional Evaluation Of MicroRNAs And Their Target Genes That Regulate Breast Cancer Metastasis

Summary
Breast cancer is the major cause of cancer-associated death in Australian women. Once the disease has spread to other organs, as occurs in about 20% of cases, our ability to treat the disease is limited and mortality is high, leading to an enormous social and economic cost New therapies for advanced disease are needed urgently. To facilitate this, we need to understand the molecular regulation of metastasis to distant organs and use this knowledge to develop new molecular targeted therapies.
The Role Of CD30 Overexpression In CD30-positive Non-Hodgkins Lymphomas

Summary
The CD30 molecule sits on the surface of normal blood cells, but in a type of cancer called Lymphoma, CD30 concentration is high. The level of expression of CD30 may determine if the cancer cell is killed by the normal defense mechanisms or is able to grow uncontrollably. We are studying the control elements of the CD30 gene to understand how control is lost when the cell becomes cancerous. This knowledge may lead to therapeutic strategies to control lymphoma.
