Summary
Glaucoma is the commonest cause of irreversible blindness in the world. Recently, through genetic studies in cohorts of blinding glaucoma cases from Australia, our group has found that variants in two genes increase the risk of blinding glaucoma. This project will investigate how these genes contribute to pathological changes in the optic nerve and retina, at the back of the eye, that lead to glaucoma. This knowledge will be useful for developing new strategies to treat glaucoma.
Minimally-invasive Gene Delivery Of A Novel Inhibitor Of Retinal Angiogenesis

Summary
Excessive growth of blood vessels in the eye causes vision loss and can only be treated with lasers or painful and frequent injections into the eye. Vasostatin is a specific inhibitor of angiogenesis and a promising agent for the management of ocular neovascularisation. We will provide pre-clinical evidence that gene delivery of vasostatin-like peptides is an effective therapeutic strategy and it has potential to revolutionize the current ophthalmic care of age-related macular degeneration.
A System For Measurement Of Vision-specific Quality Of Life Using Item Banking And Computer Adaptive Testing (ViSBank)

Funding Amount
$831,155.00
Summary
When evaluating medical treatments, it is important to consider all effects from the patient’s perspective; their quality of life. This project utilises new technology to develop an adaptable, computerised, internet-based system to measure the effects of eye diseases and their treatments on patients’ quality of life. This system will provide for more accurate, precise and efficient measurement than existing methods.
Nanoparticle-based Anti-VEGF Treatment For Ocular Neovascularization

Funding Amount
$576,921.00
Summary
Diseases like AMD and DR are the leading cause for substantial and irreversible vision loss as a direct effect of pathologic ocular neovascularization and have a significant economic impact on individuals, families, health systems and countries. Nowadays, the treatment requires frequent intravitreal injections of anti-VEGF antibody with all the risks of an invasive intraocular procedure. Nanotechonoly-based drug delivery system will provide a less invasive treatment for this kind of disease.
Brm And Brg-1 Protect From Ultraviolet Radiation-induced Skin And Ocular Damage

Summary
Ultraviolet radiation within sunlight is the most important environmental hazard to which Australians are exposed. It causes cancers of the skin and eye, in addition to other forms of skin and eye damage. However sunlight also has health benefits such as vitamin D production. To protect our health from the sun we need to understand how it causes damage and the meachanisms involved. We have discovered a new pathway that we plan to study, called Brm and Brg-1, that provides protection from UV.
How The Environment And Epigenetics Affect The Brain Disease Gene, MAPT.

Summary
Genetic variants in the microtubule associated protein Tau (MAPT) gene are major risk factors for Alzheimer’s disease and Parkinson’s disease. Environmental or lifestyle factors, such as diet and smoking, have crucial roles in changing the risk of developing these diseases. These environmental factors may exert their influence via a mechanism known as "epigenetics". This project aims to determine whether the MAPT gene is susceptible to epigenetic changes by environmental factors, and whether thi ....Genetic variants in the microtubule associated protein Tau (MAPT) gene are major risk factors for Alzheimer’s disease and Parkinson’s disease. Environmental or lifestyle factors, such as diet and smoking, have crucial roles in changing the risk of developing these diseases. These environmental factors may exert their influence via a mechanism known as "epigenetics". This project aims to determine whether the MAPT gene is susceptible to epigenetic changes by environmental factors, and whether this process will have an impact on these diseases.Read moreRead less
Defining The Changes In Cell Biology Caused By PRESENILIN Truncations Associated With Different Diseases

Summary
Truncations of the PRESENILIN genes in humans can cause two very different diseases: inherited, early onset Alzheimer’s disease (familial Alzheimer's disease) and a skin disease named inherited Acne Inversa. One truncation is also involved in the non-inherited, late onset form of Alzheimer’s disease. Why do these different truncations produce different diseases? Investigating this question will teach us more about the molecular bases of these different diseases. This understanding will be requir ....Truncations of the PRESENILIN genes in humans can cause two very different diseases: inherited, early onset Alzheimer’s disease (familial Alzheimer's disease) and a skin disease named inherited Acne Inversa.

Human Olfactory Neurosphere-derived Cells: A Novel Cellular Model For Parkinson's Disease.

Funding Amount
$365,126.00
Summary
ParkinsonÍs disease (PD) is an incurable, brain disease that affects 75,000 Australians with great societal cost. We are working on adult stem cells called (hONS) grown from peopleÍs olfactory mucosa (in the nose) as a research tool to study PD. Our project examines differences seen in hONS from people with PD and determines how certain cellular processes impact on the function of these cells. This work will enhance our understanding of the biology of PD and identify new targets for therapies.
New High Thoughput Animal Models To Investigate Amyloid Beta Toxicity

Funding Amount
$402,223.00
Summary
Amyloid-beta is widely considered to cause Alzheimer’s disease. The majority of amyloid-beta in Alzheimer's disease brains is found as shortened forms. The role of these shortened forms is uncertain and are not being tested in current animal models. We propose to develop new models to determine and compare their respective toxic effects, and to use these new models to help identify drugs to treat Alzheimer's disease.
Defining The Central Role Of Podocyte Depletion In The Development, Progression And Management Of Glomerular Disease

Funding Amount
$690,855.00
Summary
Podocytes are key cellular components of the kidney’s filtration barrier. Podocyte depletion (cell loss or injury) is a key event in most forms of kidney disease. We will investigate interactions between podocyte depletion and two major risk factors for kidney disease (diabetes and hypertension), assess whether podocyte depletion influences therapeutic outcomes, and commence efforts to develop podocyte-specific therapies.
