Summary
In cataract the clear lens in the eye becomes opaque causing blindness. Cataract is very common in the elderly, but is rarely also seen in babies and children. In babies certain gene defects, and in the elderly the genes and environmental factors contribute to cataract. The EPHA2 gene causes cataract in both young and old people. This project aims to understand how EPHA2 and other related genes cause cataract in young and old people, to prevent, delay or improve its treatment in the future.
Using Modelling To Evaluate STI Epidemiology Control Strategies And Investigate Chlamydial Within-host Disease

Summary
This research will further our understanding of the mechanisms that give rise to the development of Chlamydia within a cell and how it causes disease, ultimately providing targets for drug-vaccine design. This project will also design and evaluate epidemic control strategies to inform policy makers for reducing the incidence and prevalence of sexually transmitted infections. These applications are addressed by developing mathematical models, biophysical theory, and statistical analyses.
How Does Fra-1 Regulate The Invasive Properties Of Tumour Cells?

Funding Amount
$468,119.00
Summary
Most cancer deaths occur when tumours spread and destroy vital body functions. The invasion of tumour cells into surrounding tissue is a critical step during the spread of cancer. This project aims to unravel the molecular mechanisms that control the ability of tumour cells to invade into surrounding tissue and subsequently spread to other sites in the body. We expect to identify potential targets to better diagnose and treat the spread of cancer.
What Contributes To Regional Vulnerability In Neurodegenerative Diseases? A Study Of Familial Cases.

Summary
Unfortunately, as many people live longer, more and more are afflicted by degenerative changes that affect their brain. These neurodegenerative diseases are usually relentlessly progressive and with time render patients incapable of many normal functions. For some families with certain genetic defects, these diseases occur aggressively and early. We would like to study the brains of patients from these families because in most cases the proteins affected by the gene defect have been identified. ....Unfortunately, as many people live longer, more and more are afflicted by degenerative changes that affect their brain. These neurodegenerative diseases are usually relentlessly progressive and with time render patients incapable of many normal functions. For some families with certain genetic defects, these diseases occur aggressively and early. We would like to study the brains of patients from these families because in most cases the proteins affected by the gene defect have been identified. However, despite knowing this important information, the reasons for the death of brain cells are still not understood. This project will provide important new information on which brain cells died in these patients and on the relationship between such cell death and any cellular protein changes. By comparing patients with different genetic defects we will be able to identify the main cellular mechanisms underlying these degenerative changes. This information is essential for the rational design of further experiments aimed at reducing the suffering of all patients with neurodegenerative diseases or at eliminating these diseases altogether.Read moreRead less
For Every Question, There Is An Answer: Application Of Genomic Sequencing And Functional Genomics For Disease Gene Discovery In Children With Orphan Phenotypes

Summary
My PhD study will look closely at the genes in a family to see what is different and whether this difference is the cause of rare health problems. I will focus on children with highly unique conditions in which intellectual disability/developmental delay is a key feature. My study is important because if I can find the exact cause of rare genetic conditions, then I hope to improve the welfare of patients and families affected by these types of conditions.
Gene Discovery And Pathobiology In Muscle Diseases

Summary
I aim to find the genetic causes of muscle diseases that are lethal or severely debilitating. These diseases result in a significant burden to the affected individuals and their families and also on Australia’s Health care system. A genetic diagnosis provides families with answers, allows family planning, such that couples do not have another affected child, enables appropriate clinical management and gives researchers evidence as to how to develop treatments.
Mechanisms Of Action Of The Trefoil Peptides In Promoting Healing In Models Of Inflammatory Bowel Disease

Summary
Preliminary experiments from our laboratory have shown that members of a family of small proteins called trefoil peptides, found naturally in the stomach, intestine and colon, are able to shorten the healing time of ulcers and reduce inflammation, in an animal model of inflammatory bowel disease. Crohn's disease and ulcerative colitis together make up the human inflammatory bowel diseases, or IBD for short.

Crohn's disease and ulcerative colitis together make up the human inflammatory bowel diseases, or IBD for short. They afflict many members of the community, are debilitating, expensive to treat, and current treatments like corticosteroids and suppressors of the immune system have unpleasant and health-threatening side effects. There are therefore good reasons for the development of new forms of therapy which will be better tolerated and which are specific in their actions. We believe that the trefoil peptides may be good candidates on which new treatments for inflammatory disease might be based. The studies outlined in this proposal will test the best route of administration, and how often to give trefoil peptides in order to relieve the symptoms of experimental IBD. In addition the effectiveness of the trefoils will be compared to other agents currently used in IBD treatment, or which are known to relieve inflammation or speed the healing of the ulcerated colon. We will also carry out experiments designed to work out the mechanisms by which the trefoils' healing effects are mediated, and finally we will characterise a new member of the trefoil peptide family which we have recently discovered.Read moreRead less
Mechanisms Of Cortical And Respiratory Degenerations In Amyotrophic Lateral Sclerosis

Summary
This study will be the first to chronicle how and when motor neurons (MNs) in the brain and spinal cord degenerate before, during and after ALS symptoms in 2 different mouse models. The MNs studied control breathing muscles and are a key disease progression and mortality indicator in patients. I expect drastic shape and electrical abnormalities, providing information useful to clinicians about how and when brain and spinal cord MNs degenerate, uncovering new therapeutic targets and time-points.
A -induced Cell Death Signalling By The P75 Neurotrophin Receptor.

Funding Amount
$546,382.00
Summary
The amyloid peptide A is central to the cause of Alzheimer's disease. We have recently found that A can activate the cell death receptor p75NTR which is found in the nerve cells that die in Alzheimer's disease. This project will study whether this death pathway underpins the neuronal death associated with Alzheimer's disease. It will also determine the mechanism by which A activates p75NTR death signalling, and identify biochemical ways to prevent this from occurring.
Controlling The Development And Function Of Hindbrain Commissures In Vertebrate Animals: The Role Of Robo3 Receptor

Funding Amount
$393,834.00
Summary
Commissural axons connect and coordinate activity between neurons of the left and right sides of the central nervous system. In the forebrain, formation of commissural axons is determined by guidance factors at the midline between the two hemispheres, and abnormalities in guidance can cause developmental malformations. The aims of this project are to elucidate function of the Robo/Slit family of molecules in regulating axon guidance of commissural neurons, particularly in the corpus callosum.
