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.
Functional Analysis Of Recently Identified Novel Glaucoma Genes.

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.
Membrane Attachment And Components Of The Ca2+ -triggered Release Mechanism

Summary
Understanding and harnessing the fundamental cellular process of secretion will provide a wealth of new approaches to addressing problems associated with aging & disorders that are major health care burdens (e.g. neurodegeneration & diabetes). Understanding the vesicle docked state, and the contributions of different molecular components to the release process provides for unique insights into the underlying molecular mechanisms, thereby enabling safe, targeted control of this critical process.
Clarifying The Clinical Application And Mechanisms Of Pedunculopontine Nucleus Deep Brain Stimulation For Parkinson’s Disease

Summary
Over 64,000 Australians have Parkinson’s disease. Most patients with Parkinson’s disease ultimately develop gait ‘freezing’ and poor balance, which impair quality of life and cause falls. Unfortunately, gait freezing and poor balance often don’t improve with conventional treatments. We are therefore helping to develop a new treatment for these symptoms, which involves implanting a pacemaker into a very deep region in the brain called the “Pedunculopontine Nucleus’.
Piezo2 And Pain - Is There A Role For Piezo2 In Mechanically Induced Bone Pain?

Funding Amount
$543,848.00
Summary
Pain associated with bone marrow edema, osteoarthritis, bone cancer and fracture puts a significant burden on individuals, society, and the health care system in Australia. A dominant feature of these includes mechanical disturbances of the bone, and this is a trigger for the pain. In this study, we will determine if a newly discovered mechanically gated ion channel (Piezo2) is a key contributor to mechanically induced bone pain and could be a target for development of drugs to treat it.
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.

Targeting MiRNA To Inhibit Leukocyte Differentiation: A Novel Anti-inflammatory Approach For The Treatment Of Asthma
Funder
National Health and Medical Research Council
Funding Amount
$601,386.00
Summary
In asthma, the symptoms are caused by an allergic reaction in the lung and the production of inflammatory cells whose maturation is guided by tiny molecules called “microRNAs”. The critical microRNAs will be identified and strategies to block their function developed and tested for their ability to inhibit allergic inflammation to evaluate this approach as a new treatment for asthma.
Elucidating The Role And Potential For Therapeutic Targeting Of TLR7 In Emphysema And COPD

Funding Amount

Summary
Emphysema is a major cause of illness and death and there are no effective treatments. It is caused by smoking that damages the airways and air sacs but how this occurs is not well understood. We have found that a new factor, called Toll-like receptor 7, is involved in emphysema. In this study we will now characterise its roles in this disease, work out how it induces emphysema and test new inhibitors (antibodies) that we have developed as treatments.
Irritable Bowel Syndrome (IBS) is one of the leading causes of chronic pain both world-wide and in Australia for which there is a lack of treatments. Chronic pain arises from nerve fibres in the colon wall, which fail to 'reset' back to normal following inflammation. Targeting these nerve endings with drugs is a key advance in IBS treatment. This project will identify selective oxytocin analogues that act in the colon to lower pain in sensory nerves thus providing efficacious pain relief in IBS.
Determining Shared Genetic Control Of RNA Transcription Across 45 Human Tissue Types

Funding Amount
$264,684.00
Summary
There is strong evidence that much of the genetic susceptibility to disease acts through altering way genes are turned into proteins via RNA transcripts. One important problem in using transcriptomic data to study diseases is that the genetic control of RNA transcription is known to vary between tissues. This study will use new methods and RNA data from 45 human tissues to show the degree of common genetic control for each RNA transcript between each pair of tissues.
