Summary
Liver disease is a serious health problem. Viral hepatitis, obesity and alcohol can result in end-stage liver disease. Organ transplant is the only treatment available. A widening gap between organ donations and recipients mandates alternative treatments are developed. Cell transplantation and artificial liver devices are alternatives which can use liver progenitor cells. We will investigate how factors grow and convert them into liver cells for treating liver disease patients.
When Prometheus Needs A Hand – How Human Amnion Epithelial Cells Resolve Fibrosis And Regenerate The Liver

Summary
Cirrhosis can progress to end stage disease for which transplantation provides the only hope for survival. Liver donors in Australia are scarce; the need for donor organs is increasing. Using stem cells to repair and regenerate damaged liver may provide an alternative to organ transplantation. We are studying placental stem cells that can decrease inflammation and increase progenitor cells to repair and regenerate liver. Our goal is to use these stem cells as treatment for human liver disease

Summary
We have developed a new high-resolution optical imaging technology. The unique aspect of our research has been to redesign the imaging probe, miniaturising it to a few hundred microns in diameter, and encase it in a hypodermic needle – a ‘microscope-in-a-needle’. We are developing specific imaging probes to aid in the assessment of lung disease; the diagnosis of liver disease; and integrated into a brain biopsy needle to enable safer brain biopsies.

Summary
Alzheimer's disease (AD) is a progressive memory disorder. Increased production of a short peptide called amyloid- (A ) aggregates to form the sticky masses in the brains of AD patients. The amount of A in the brain is a balance between production and clearance. Surprisingly, we recently demonstrated that the liver clears the majority of A . These results connect AD and cardiovascular disease (CVD), enabling current CVD therapeutics to target A clearance by the liver.
Re-uniting marsupials and eutherians by embryonic micromanipulation. The unique responsibility for transmitting life from generation to generation normally depends on the gametes. This project will use new reproductive technologies to investigate the properties of the oocyte in reprogramming somatic cell nuclei, and will use the nuclei of both marsupial and eutherian somatic cells to test this. We will also use both marsupial and eutherian genes to insert into the oocyte to create the first tra ....Re-uniting marsupials and eutherians by embryonic micromanipulation.

We will also use both marsupial and eutherian genes to insert into the oocyte to create the first transgenic marsupials. We will also investigate the ability of spermatozoa from species of increasing genetic distance to ferttilise marsupial eggs using intracytoplasmic sperm injection (ICSI).Read moreRead less

Summary
Iron is crucial for many essential biological processes. Recently, we demonstrated that iron-depletion can affects important signalling pathways (e.g., JNK and p38) that play important roles in growth arrest and apoptosis. This study is designed to investigate the cellular and molecular effects of iron depletion which currently remains unclear. The research is crucial for understanding: (1) the effects of iron deficiency and (2) for understanding the effects of iron chelators that are used for t ....Iron is crucial for many essential biological processes.

An X-ray crystallographic investigation into co-receptors on T-lymphocytes. T lymphocytes are an indispensable cellular component of the immune system. The normal process of T cell selection in the thymus, and the ability of mature T cells to respond to foreign antigens are governed by receptor recognition and co-receptor mediated events. The co-receptors encompass a wide spectrum of structurally diverse proteins that are involved in adhesion, co-ligation and signal transduction. This proposa ....An X-ray crystallographic investigation into co-receptors on T-lymphocytes. T lymphocytes are an indispensable cellular component of the immune system.

The co-receptors encompass a wide spectrum of structurally diverse proteins that are involved in adhesion, co-ligation and signal transduction. This proposal aims to investigate, using X-ray crystallography as the primary research tool, co- receptors located on T-lymphocytes. This work will gain fundamental insights into co-receptor function.Read moreRead less
Is transport of miRNAs essential for plant development? This project will provide knowledge of how a new class of biologically active molecule (micro RNA) regulates expression of genes at sites in the plant that are critical for growth and development. MicroRNAs are believed to influence the size and shape of plants, how rapidly they grow and how well they produce and fill seeds. These molecules are part of a group of bioactive signals that move throughout the plant, functioning like hormones bu ....Is transport of miRNAs essential for plant development? This project will provide knowledge of how a new class of biologically active molecule (micro RNA) regulates expression of genes at sites in the plant that are critical for growth and development. MicroRNAs are believed to influence the size and shape of plants, how rapidly they grow and how well they produce and fill seeds. These molecules are part of a group of bioactive signals that move throughout the plant, functioning like hormones but directly influencing how well critical genes work. Their exploitation holds great promise for manipulating plant performance and enhancing crop yields. Read moreRead less
