This project is included in the designated priority area of research Promoting and Maintaining Good Health and Ageing Well. It represents a mouse model to assist in the study of human disease. It is the first mouse model for SMG-1, a protein kinase that protects against a variety of different forms of stress. The strength of the model is that it can be combined with other mouse models to interrogate and elucidate the events occurring in different pathways for stress. The expectation is that ground-breaking data will be generated with this model providing scientific leadership on the role of this protein. It will also assist in establishing new collaborations.Read moreRead less
The biological and pathological functions of TDP-43. The social and economic burden of neurodegenerative such as MND is enormous. A key histopathological hallmark of this and many other related diseases are deposits of the protein TDP-43. Our research aims at understanding its largely unknown functions, for example by generating transgenic animal models. These will form the base for the development for a TDP-43-directed drug treatment. The national benefit of this research is manifold: by deciph ....The biological and pathological functions of TDP-43. The social and economic burden of neurodegenerative such as MND is enormous. A key histopathological hallmark of this and many other related diseases are deposits of the protein TDP-43. Our research aims at understanding its largely unknown functions, for example by generating transgenic animal models. These will form the base for the development for a TDP-43-directed drug treatment. The national benefit of this research is manifold: by deciphering basic biological mechanisms, patenting new data, developing treatment strategies for un-curable and fatal disorders, and expanding links to Australian biotech and international pharmaceutical companies.Read moreRead less
Role of 3'-phosphorylated phosphoinositides in neurosecretion. Neurons communicate through the release of neurotransmitter by synaptic vesicles. Minute changes underlie normal processes such as memory and modifications of neurotransmitter level contribute to a number of neurological diseases. I am interested in deciphering the role of phosphoinositides, an inner membrane-based lipid, during steps leading to the fusion of a synaptic vesicle with the plasma membrane. I have recently discovered tha ....Role of 3'-phosphorylated phosphoinositides in neurosecretion. Neurons communicate through the release of neurotransmitter by synaptic vesicles. Minute changes underlie normal processes such as memory and modifications of neurotransmitter level contribute to a number of neurological diseases. I am interested in deciphering the role of phosphoinositides, an inner membrane-based lipid, during steps leading to the fusion of a synaptic vesicle with the plasma membrane. I have recently discovered that phosphatidylinositol-3 phosphate production was critical for the vesicle to acquire the competence to fuse with the plasma membrane. This project aim to understand by which mechanism this lipid interacts with the release machinery to promote such priming step.Read moreRead less
Characterisation of the novel mitochondrial protein (CABC1/ADCK3) and its role in protecting against oxidative stress. This is the first detailed characterisation and mechanistic study on a protein that protects against oxidative stress and neurodegeneration. Demonstrating the basis for this oxidative stress and its possible contribution to the cellular phenotype will be of benefit in understanding the disease process and ultimately designing approaches to minimise oxidative stress. An investiga ....Characterisation of the novel mitochondrial protein (CABC1/ADCK3) and its role in protecting against oxidative stress. This is the first detailed characterisation and mechanistic study on a protein that protects against oxidative stress and neurodegeneration. Demonstrating the basis for this oxidative stress and its possible contribution to the cellular phenotype will be of benefit in understanding the disease process and ultimately designing approaches to minimise oxidative stress. An investigation of this protein presents an opportunity for the investigator to work at the forefront in this field adding to Australia's scientific leadership in the area. It also represents an ideal project for post-graduate training and is a collaboration between groups in Brisbane and Melbourne. Read moreRead less
