Summary
This project will study how cancer cells are forced out of their original tissue of origin. This process, called oncogenic extrusion, is important to allow cancer cells to proliferate and invade their surrounding tissue. We have discovered a new cellular mechanism that causes oncogenic extrusion and aim to understand its molecular basis and test how it contributes to breast cancer.

Summary
This project will investigate a novel approach to controlling how cancer cells grow and spread. It plans to study whether a protein termed N-acetyltransferase is a key to determining whether cancer cells can change thier characteristics, allowing them to invade other tissues. In addition, novel approaches to target this protein are proposed. If successful, the work outlined in this project will open new avenues to understanding and trerating cancers.

Summary
Chronic kidney disease (CKD) is a major cause of death and disability in the Australian population. Current treatments for CKD are non-specific and frequently ineffective. As a consequence, kidney failure progresses to the stage where patients require dialysis or transplantation to remain alive. Every year more than 1700 Australians require kidney replacement therapy for this reason and many more die of kidney failure or its complications. Kidney fibrosis is the final common result of diverse CK ....Chronic kidney disease (CKD) is a major cause of death and disability in the Australian population. Current treatments for CKD are non-specific and frequently ineffective. As a consequence, kidney failure progresses to the stage where patients require dialysis or transplantation to remain alive. Every year more than 1700 Australians require kidney replacement therapy for this reason and many more die of kidney failure or its complications. Kidney fibrosis is the final common result of diverse CKD. This project proposes to investigate EMT, a key event in the development of renal fibrosis, whereby kidney cells are converted to fibrogenic cells. The project focuses on matrix enzymes (metalloproteinases) and E-cadherin (a molecule which is involved in adherence of kidney cells to one another, but which we think may actually be involved in the causation of EMT). This focus is novel, and could provide new understanding about the process of EMT in renal fibrosis, knowledge relevant to all diseases characterised by eventual loss of organ function due to fibrosis. It will identify new targets for therapy aimed at preventing fibrotic diseases of all types.Read moreRead less
This work will analyse how cells, the building blocks of tissues, are organized together to form functioning organs. It focuses on the adhesion molecules that allow cells to recognize one another, which cooperate with the internal skeleton of cells to link them together. We aim to understand how these cellular systems work normally and how they are targeted to disrupt tissue integrity in diseases like cancer and inflammation.
Cortactin: Integrating Cadherin Signalling For Junctional Integrity

Summary
Adhesion between cells holds the human body together and affects many aspects of our health, including normal tissue and organ function. Importantly, loss of normal cell-cell adhesion contributes to many diseases, including cancer and inflammation. One key adhesion molecule, E-cadherin, is necessary for many epithelial tissues and its function is perturbed in disease. This research project addresses how E-cadherin signals into cells to control cell-to-cell interactions.

Summary
Interactions between cells and their neighbouring cells control many important processes in the body. The adhesion molecule, E-cadherin, is a major protein that controls interactions between cells in epithelial tissues (e.g. breast, lung, gut). E-cadherin is essential for these tissues to form normally, and loss of E-cadherin function contributes to the progression of many human cancers (especially common cancers such as breast and lung).

The adhesion molecule, E-cadherin, is a major protein that controls interactions between cells in epithelial tissues (e.g. breast, lung, gut). E-cadherin is essential for these tissues to form normally, and loss of E-cadherin function contributes to the progression of many human cancers (especially common cancers such as breast and lung). Understanding how E-cadherin controls normal epithelial cell function will therefore provide key insights into the bases for tumor progression. In this study we will examine how E-cadherin signals to the interior of cells. We have recently discovered a new signaling pathway that is turned on when E-cadherin is activated. Understanding the fundamental elements of this signaling pathway will provide invaluable insights into how cells recognize one another during health and disease.Read moreRead less

Understanding how E-cadherin controls normal cell function in these tissues will therefore provide key insights into how disease arises. In this study we will investigate how a protein which binds to E-cadherin, cortactin, contributes to the biological effect of E-cadherin in supporting tissue architecture. Understanding the fundamental elements of how cortactin works with E-cadherin will provide invaluable information into how cells recognize one another in health, and fail to adequately recognize each other in common diseases.Read moreRead less
