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.
Translating Disordered Iron Metabolism And Liver Injury Research Into Clinical Practice

Funding Amount
$444,014.00
Summary
Disorders of iron excess or insufficiency are common. A major complication of iron overload is liver disease. Another major cause of liver disease is nonalcoholic fatty liver disease. Most causes of liver disease injure the liver by similar mechanisms. This project will discover new mechanisms by which iron may cause cancer, arthritis, liver and cardiac disease and will define new diagnostic tests and treatments for disorders of iron metabolism and liver disease.
Delineating The Clinical And Molecular Heterogeneity Of Fatty Liver Disease To Inform Treatment

Funding Amount
$1,731,372.00
Summary
Fatty liver disease from excess weight affects 1 in 3 adult Australians. The disease has no treatments and many patients develop liver failure or liver cancer. Clinically, the disease is characterized by marked heterogeneity, a challenge for developing biomarkers and treatments. To move towards precision medicine, this project will undertake an inter-disciplinary program that embraces disease complexity and integrates environmental and genetic risk with the power of mathematical modelling.
The Epidemiology And Burden Of Liver Disease In Australia With An Emphasis On Non-alcoholic Fatty Liver Disease.

Summary
Non alcoholic fatty liver disease is now the commonest cause of abnormal liver function in Australia due to its close association with the obesity epidemic. It is likely to become the leading cause of liver failure and liver cancer over the next few decades. Despite this, the prevalence in Australian populations is unknown. The aim of this project is to assess how common this disorder is, the burden it places on the healthcare system and the effectiveness of treatment for liver cancer caused by ....Non alcoholic fatty liver disease is now the commonest cause of abnormal liver function in Australia due to its close association with the obesity epidemic.

Discovering New Biomarkers In Hepatocellular Carcinoma

Summary
Liver cancer is a leading cause of cancer death with increasing rates and a high mortality. The project will develop new methods to predict liver cancer risk and outcomes using circulating samples rather than invasive biopsies. Our data shows that tissue and cells shed specific blebs into the circulation and these can contain unique information about the tissue of origin. We propose a series of experiments to show that these circulating samples are able to predict risk and outcomes with liver
Studies On The Pathogenesis And Early Diagnosis Of Hepatocellular Carcinoma

Funding Amount
$100,082.00
Summary
Hepatocellular carcinoma (HCC) is the most common primary liver cancer and worldwide is the third and fifth leading cause of cancer death in men and women respectively. Early diagnosis is vital to patient survival. Our research investigates new methods in the early diagnosis of HCC, including new protein markers of the cancer and non-invasive measurements of liver scarring. We also study the genetics of HCC and investigate new genes that could be targets for future therapies.
The Role Of TNF And Its Receptor Family In Liver Progenitor Cell Proliferation And Differentiation

Summary
Maintaining liver function is essential for health, and compromising this ultimately results in death. The liver is unusual, as it can regenerate to replace lost or damaged tissue. Recently it has been established that there are two pathways to liver regeneration. One involves hepatocytes, and this is normally associated with acute liver damage. The other, involves liver progenitor cells; and this is usually observed when there is chronic and severe liver damage, particularly when the proliferat ....Maintaining liver function is essential for health, and compromising this ultimately results in death. The liver is unusual, as it can regenerate to replace lost or damaged tissue. Recently it has been established that there are two pathways to liver regeneration. One involves hepatocytes, and this is normally associated with acute liver damage. The other, involves liver progenitor cells; and this is usually observed when there is chronic and severe liver damage, particularly when the proliferation of hepatocytes is impaired. This study seeks to understand the underlying mechanisms which recruit liver progenitor cells for regeneration. This knowledge can lead to strategies to augment the oval cell contribution to liver regeneration in cases of chronic liver damage, to enhance survival of the patient. It can be applied to strategies to grow and maintain liver stem cells in culture for the purpose of cell and gene therapy to correct liver dysfunction. It is also necessary to identify factors which affect oval cells and understand their mechanism of action because of their link to liver cancer. Oval cells have a Jekyll and Hyde characteristic, and it is important to know what leads them towards liver differentiation and regeneration, and what makes them produce liver cancers.Read moreRead less
Understanding The Role Of Sugar Metabolism In Liver Tumour Growth

Funding Amount
$631,979.00
Summary
Primary liver cancer is a deadly disease with limited chemotherapeutic options. The investigators of this proposal have recently determined that sugar intake (but not fat or complex carbohydrate) is a dominant driver of liver tumour growth in mice. The current proposal will investigate the specific contributions of glucose versus fructose in tumour burden, and determine whether blocking the conversion of sugars to fat in the liver represents a therapeutic strategy to block tumour growth in mice.
