Summary
Breast cancers are made up of different types of cancer cells, and not all cells contribute equally. A subset of cancer cells may be uniquely capable of driving tumor growth, rebuilding fatal tumors after therapy and establishing new tumors at distant sites. Identifying and exploiting the pathways that regulate the activity and survival of these cells will lead to better modes of treatment, and move towards a relapse-free future for breast cancer patients.

Summary
Metastasis of melanoma cells away from the primary tumour site carries a very poor patient prognosis.This research aims to characterise a novel signalling pathway that can regulate the migration (movement) of melanoma cells. This signalling pathway depends on force-sensing platforms that can rapidly convert physical inputs from the environment into an electrical signal within the cell. We are working to understand how these force-sensors function.
The cells that produce and maintain our cartilage, known as chondrocytes, do so by sensing changes in the mechanical environment, but precisely how chondrocytes detect these changes is not known. We are investigating the role of ion channels that are opened in direct response to mechanical movements within the cartilage.This project plans to identify the specific molecules that are participating in this process and to determine if they are therapeutic targets for treatment of osteoarthritis
Transient Tissue ‘priming’ Via FAK Inhibition To Impair Pancreatic Cancer Progression And Improve Sensitivity To Gemcitabine/Abraxane

Summary
The success of cancer drugs is dependent on many factors including the properties of the tumour tissue. As a tumour grows it changes the tissue around it, and this affects response to treatment. Combining classical biology with engineering to generate 3D models that mimic tumours, along with cutting-edge imaging technology and mouse models, we will target FAK-controlled cancer cell pathways that sense tissue changes, together with already approved cancer drugs to improve patient outcome.

Summary
Inefficient drug response in solid tumour tissue is commonly a limiting factor in the clinical effectiveness of cancer therapies. Using cutting-edge imaging technology and 3D models that mimic the disease, we have mapped areas of poor drug response within distinct regions of tumours. Here, we pinpoint and specifically target key factors limiting efficient drug targeting in order to improve the encouraging anti-cancer profile of the new drug combination Gemcitabine/Abraxane in pancreatic cancer.

Summary
Using cutting-edge imaging technology and 3D models that mimic cancer, we can map areas of poor drug response within distinct 'stages' or regions of tumours. Here, we pinpoint and specifically target key factors limiting efficient drug response in order to improve the encouraging anti-cancer profile of new or current drugs in pancreatic cancer.
Modelling TRPV4 Skeletal Disorders Using Human IPSCs

Summary
Inherited skeletal disorders are a significant disease burden. Many gene mutations have been defined but we only have limited understanding about how they cause the disease. We will use patient skin cells and new in vitro re-programing technology to induce them to form cartilage cells to produce “disease in a dish” models of human skeletal disorders. These models will allow us to answer questions about how specific mutations cause disease and identify potential therapies
GABA(B) Receptor Modulation Of Gastrointestinal Function In Health And Disease By Alpha-Conotoxins

Summary
Chronic visceral pain is a common and debilitating condition arising from numerous diseases that affect our internal organs. There is a desperate need for more information about the mechanisms responsible for signalling chronic visceral pain to provide therapies and potentially find a cure for it. Our research focuses on ?-conotoxins (small peptides from marine cone snail venom) as novel potential therapeutic agents for the treatment of chronic visceral pain.

Summary
The thin layer of fluid covering the surface of the air passages acts to protect the airway surface from drying. This fluid also allows the hair-like projections, or cilia, on the top of the airway cells to beat more effectively. The volume and composition of this fluid is determined by the movement of salt and water across the mucous membranes of the air passages. The importance of this fluid is shown by the problems that occur in Cystic Fibrosis (CF), the most common lethal inherited disease a ....The thin layer of fluid covering the surface of the air passages acts to protect the airway surface from drying. This fluid also allows the hair-like projections, or cilia, on the top of the airway cells to beat more effectively. The volume and composition of this fluid is determined by the movement of salt and water across the mucous membranes of the air passages. The importance of this fluid is shown by the problems that occur in Cystic Fibrosis (CF), the most common lethal inherited disease affecting Australians. In CF, altered salt transport causes drying of the airway surface which impairs the working of the cilia. This leads to retention of mucous in the airway with repeated bacterial infections damaging the lungs. Simple tests have been designed to directly measure the movement of salt across the surface of the nasal passage using a fine soft rubber tube. Movement of mucous in the nose is measured using other simple techniques that are currently used diagnostically. Together, these tests in the nose provide vital information about how the surface of normal human airway moves salt, water and mucous. Any differences found in CF patients will then give us a good idea of the problems found in the CF lung. We will study the interactions between calcium, sodium and chloride in the fluid lining the airways, measuring changes in salt and mucous movement. A range of testing procedures will be used in human volunteers, anaesthetised mice and isolated tissues from sheep. We have already demonstrated important links between the fluid lining the airways and salt movement, and we expect that this may lead to the development of new treatments for Cystic Fibrosis. This therapy will focus on treating the lung problems of CF patients, the major cause of disability. We anticipate that this preventative therapy may offer real benefits in the fight to cure CF.Read moreRead less
