The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.

Significance Of Microparticles In The Pathogenesis Of Liver Ischemia Reperfusion Injury
Funder
National Health and Medical Research Council
Funding Amount
$643,958.00
Summary
The overall aim of the project is to investigate the significance of microparticles in liver ischemia reperfusion injury (IRI). IRI causes damage to donor livers stored in preparation for liver transplantation. We postulate that microparticles released from the liver are critical in this form of injury. The expected outcomes are novel insights into liver IRI with the aim of developing new approaches to prevent liver damage during liver surgery, transplantation and shock.
Unraveling Mechanisms Of Liver Transplant Tolerance
Funder
National Health and Medical Research Council
Funding Amount
$694,822.00
Summary
Liver transplants are unique amongst solid organs as they are spontaneously accepted across different individuals and induce acceptance of other organs from the same donor co-transplanted at the same time. Using a new mouse liver transplantation model, this proposal will elucidate how the liver tissue performs this function and identify new markers associated with tolerance in the blood of mice. This knowledge will be used to identify liver transplant patients with reduced rejection risk.
Protecting Fatty Livers From Hepatic Ischemia-reperfusion Injury In Liver Surgery And Transplantation
Funder
National Health and Medical Research Council
Funding Amount
$624,960.00
Summary
About one third of the population have a fatty liver, and this greatly increases risks of liver failure after liver surgery or when fatty donor livers are used for transplantation (such organs are currently disposed of). The disease process is called ischemia-reperfusion injury (IRI). The investigators have recently shown that both fibrates and statins provide partial protection against IRI in fatty livers. This research is directed at establish the protective mechanisms, and whether combination ....About one third of the population have a fatty liver, and this greatly increases risks of liver failure after liver surgery or when fatty donor livers are used for transplantation (such organs are currently disposed of).

Development Of Functional Liver Tissue Engineered From Murine Hepatocyte Or Liver Progenitor Cell Spheroids To Correct Liver Disease
Funder
National Health and Medical Research Council
Funding Amount
$459,482.00
Summary
Many patients suffering from severe liver disease require a liver transplant, but due to a shortage of liver donors, many die prior to liver transplantation. This study investigates novel methods of growing liver tissue from mature liver cells called hepatocytes, or, liver stem cells implanted in a plastic chamber in mice with acute and chronic liver disease. It is anticipated that new liver tissue will grow in the chamber, the mice will be cured, and that this technique can be translated to hum ....Many patients suffering from severe liver disease require a liver transplant, but due to a shortage of liver donors, many die prior to liver transplantation.

Advanced Imaging To Define Hepatic & Intestinal Drug Disposition In Aging & Liver Diseases
Funder
National Health and Medical Research Council
Funding Amount
$762,123.00
Summary
Aged people and liver disease patients have impaired drug absorption and elimination functions. Their response to drugs varies widely when given drug dosage regimens recommended for normal patients. This project will explore the possibility of using in vivo imaging techniques to define the gut and liver function and their response to administered drugs. This grant will help the selection of appropriate drugs and doses for aged people and patients with liver diseases, i.e. personalised medicine.
Cholestasis And Hepatocyte Injury In Chronic Liver Disease
Funder
National Health and Medical Research Council
Funding Amount
$615,967.00
Summary
The aim of this project is to understand the consequences of long-term cholestasis or impaired bile excretion/flow on normal liver cells (hepatocytes) and to test whether specific bile acids can cause irreversible damage to hepatocytes leading to their transformation into pre-malignant cells and hepatocellular carcinoma (primary liver cancer). The results from this project will inform new strategies in screening, prevention and treatment of liver cancer in children and adults with cholestasis.
The Role Of MBOAT7 In Hepatic Inflammation: Implications For Therapy
Funder
National Health and Medical Research Council
Funding Amount
$848,340.00
Summary
When a fatty liver progresses to develop inflammation, patients are at-risk of liver-related morbidity and death. Currently, there are no effective therapies. From human studies, we have discovered that a lipid modifying enzyme (MBOAT7) profoundly regulates liver inflammation. In this proposal, we will obtain a detailed understanding of how the activity of this pathway modulates inflammation. We expect to show that MBOAT7 is a novel ‘druggable’ pathway for the treatment of liver inflammation.
P53 And Hepatocyte Proliferation In Chronic Liver Disease
Funder
National Health and Medical Research Council
Funding Amount
$331,360.00
Summary
The aim of this project is understand how loss of control of p53, a tumour suppressor gene, in liver cells causes the transformation of normal liver cell (hepatocyte) to ‘rouge’ pre-cancerous cells in hepatocellular carcinoma (HCC) or primary liver cancer. We will test novel therapies to restore p53 function in liver cells in order to prevent or retard the development of HCC in patients with cirrhosis and those ‘at risk’ of this rapidly increasing fatal cancer in Australia.
MERTK Receptor Tyrosine Kinase: A Novel Therapeutic Target For Liver Fibrosis
Funder
National Health and Medical Research Council
Funding Amount
$870,972.00
Summary
Hepatic fibrosis is the principal cause of liver-related morbidity and mortality, for which there are no effective therapies. Thus, there is an urgent and unmet need to identify new targets to treat liver fibrosis. We have demonstrated for the first time, that liver fibrosis correlates with elevated hepatic expression of MERTK, a receptor tyrosine kinase. This project will explore whether MERTK function can be exploited to target and reverse liver fibrosis
The Role Of The Hepatocyte And EMMPRIN In Liver Injury
Funder
National Health and Medical Research Council
Funding Amount
$607,487.00
Summary
This research plan investigates the role of the hepatocyte, the principal functional cell within the liver in the development of liver disease. Liver injury can result in end-stage scaring known as cirrhosis as well as leading to liver cancer. Our research aims to identify strategies for reversing the fibrotic process and result damage to the liver
