Summary
The steroid hormone aldosterone regulates blood pressure by controlling sodium retention. The importance of this role is underlined by the fact that all known mongenetic hypertensive conditions involve aldosterone or sodium retention. Aldosterone mediates this effect by activating an intracellular receptor protein that in turn switches on specific genes. This study seeks to identify the genes that are switched on (or off) by aldosterone and to characterise the region of the gene that interacts w ....The steroid hormone aldosterone regulates blood pressure by controlling sodium retention. The importance of this role is underlined by the fact that all known mongenetic hypertensive conditions involve aldosterone or sodium retention. Aldosterone mediates this effect by activating an intracellular receptor protein that in turn switches on specific genes. This study seeks to identify the genes that are switched on (or off) by aldosterone and to characterise the region of the gene that interacts with the receptor. Both cell and gene specific factors are thought to be important in defining the nature of this interaction; these factors will also be sought. This information will enhance our understanding of the basic biology of sodium transport in the colon and the kidney which in turn will clarify the role of aldosterone in high blood pressure, cardiac disease and perhaps even stress.Read moreRead less
Predicting Fracture Outcomes From Clinical Registry Data Using Artificial Intelligence Supplemented Models For Evidence-informed Treatment (PRAISE) Study

Summary
This project will establish the role of artificial intelligence (AI) techniques to improve the prediction of clinical and longer-term patient reported outcomes following wrist fracture. Prediction models based on existing, routinely collected registry data with will be compared with models based on registry data enhanced by AI analysis of X-ray images, radiology reports and surgical reports. The AI analysis will reason on both image and text data, better replicating how humans learn.
Rob Ramsay has had a long standing research commitment to understanding bowel and breast cancer using mouse models with defined genetic defects. These sophisticated models replicate various stages of cancer development and some have profound effects on normal tissue biology. He also uses molecular tools to investigate how genes are controlled. These approaches are providing direct input into the development of therapeutic agents for cancer treatment.
CROSSFIRE: Combined Randomised And Observational Study Of Surgery For Fractures In The Distal Radius In The Elderly

Summary
Fractures (breaks) near the wrist are the most common fractures treated. Treatment previously consisted of straightening and plaster casting in the emergency department, but standard treatment now includes admission to hospital and surgery to apply a plate and screws to the bone. The best evidence we have (which is limited) is that surgical plating does not provide important benefits over plastering. We aim to perform a multicentre trial comparing plating to plaster for these common fractures.
DOES BCL-G, A BH3-ONLY PROTEIN, PLAY A ROLE IN INFLAMMATION-ASSOCIATED COLON CANCER?

Summary
Deregulation of the function of several members of the Bcl-2 family has been shown to be an aggravating factor in autoimmune diseases and cancer. Bcl-G is a new and poorly characterized member of this family. We have produced essential tools to study the physiological function of Bcl-G, and discovered that it plays a role in inflammatory bowel disease. We now plan to investigate its possible role in inflammation-associated colon cancer.?
Investigation Of DUSP5 As A Novel Tumour Suppressor Gene In Colon Cancer

Summary
Colon cancer is the second leading cause of cancer related death in Australia. Understanding the genetic causes of this disease are essential to developing new treatment strategies. The goal of this study is to understand the role of the DUSP5 gene in colon cancer. The findings of this study has the potential to further our understanding of how colon cancers arise and for identifying patients likely to respond to specific existing treatments.
Role Of The EHF Transcription Factor In Regulating The Differentiation Status Of Colon Cancers

Summary
New treatment strategies for colon cancer are urgently needed. This application will test a novel approach for treating colon cancer based on the re-induction of differentiation of colon cancer cells, by reactivating a gene called EHF. We expect this to reduce the propensity for colon cancer cells to spread to distant organs and to increase their sensitivity to chemotherpay. This has the potential to significantly benefit the clinical management of patients with this disease.
I am a molecular-cell biologist studying the genetic regulation of intestinal homeostasis in development and disease with the aim of identifying novel molecular targets for the treatment of disease and that can be validated in relevant preclinical mouse models.
This project aims to develop a new therapy for colorectal cancer (CRC). We have already demonstrated that a molecule called PAK1 is the master regulator of several intracellular signalling pathways, and is essential for CRC growth and invasion. We now plan to study whether inhibitors that block PAK1 activity can prevent the growth of human CRC cells in the laboratory or their development into tumours in animals.
