This project aims to describe newly discovered processes by which bacteria that reside in the gut of an animal influences host mitochondria, the powerhouses of the cell. Using advanced genetic and molecular methodologies, this project aims to generate new knowledge on improving mitochondrial function as well as advance our understanding of the emerging field of microbiome research. Expected outcomes include a novel and universal technology platform in which to engineer small molecules and probiotics to improve mitochondrial health and enhance fitness in a range of animals. This should provide significant benefits, through both scientifically relevant outcomes and economic benefits through technological advancements.Read moreRead less
Investigating the role of gene loops in regulating gene expression. The ability to identify functional variants in regulatory elements will have implications for researchers in multiple fields of biology, from molecular medicine to agriculture. Transfer of expertise and application of the knowledge generated by our research to such fields stands to improve diagnosis of disease predisposition and to improve quality of animal and plant products. These outcomes will benefit all Australians. This kn ....Investigating the role of gene loops in regulating gene expression.

Transfer of expertise and application of the knowledge generated by our research to such fields stands to improve diagnosis of disease predisposition and to improve quality of animal and plant products. These outcomes will benefit all Australians. This knowledge will also improve the education of Australian University students as it contributes to the development of advanced curricula and access to more powerful research methods. In addition, the project will foster important collaborations between Australian researchers and those overseas.Read moreRead less
Signaling Pathways To Enhance Potency Of AMPK-targeting Drugs

Funding Amount
$661,966.00
Summary
Sedentary lifestyles and consumption of high energy foods has led to epidemics of obesity-related metabolic diseases that place enormous financial and medical burden on the Australian economy. An attractive drug target to treat these diseases is AMP-activated protein kinase (AMPK) which functions as both a cellular fuel gauge and co-ordinator of whole-body metabolism. Our goal is to improve AMPK drug potency by identifying novel processes that sensitize AMPK to drugs.
Engineering the defence-vigour balance for increased crop yield. This project aims to investigate a novel hypothesis to increase seed yield and vigour. Translating from a model system it will test whether the deliberate inactivation of a gene in tomato and banana, by RNA interference or genome editing, enhances performance. A dysfunctional gene in the viral defence pathway of the model plant species N. benthamiana boosted its seed yield and vigour. This project will investigate the enhancement, ....Engineering the defence-vigour balance for increased crop yield. This project aims to investigate a novel hypothesis to increase seed yield and vigour. Translating from a model system it will test whether the deliberate inactivation of a gene in tomato and banana, by RNA interference or genome editing, enhances performance. A dysfunctional gene in the viral defence pathway of the model plant species N. benthamiana boosted its seed yield and vigour. This project will investigate the enhancement, determine the consequences to the plant's defences, measure the balance between defence and vigour, and examine the risk of disease to such yield-enhanced crops. This is a radical departure from conventional approaches to crop improvement but if successful would provide an additional solution to the problem of future food security.Read moreRead less
Recombination of mitochondrial genomes: what can we learn from chigger mites? This project will bring three benefits to Australia. First, it will enhance Australia's research capacity in the fields of organelle genomics and evolutionary biology. Second, it will yield highly skilled young researchers: a postdoctoral fellow (Shao), a PhD student and two BSc Honours students. Third, it will generate new knowledge about genome recombination in animal mitochondria. Recombination is a fundamental, yet ....Recombination of mitochondrial genomes: what can we learn from chigger mites? This project will bring three benefits to Australia. First, it will enhance Australia's research capacity in the fields of organelle genomics and evolutionary biology. Second, it will yield highly skilled young researchers: a postdoctoral fellow (Shao), a PhD student and two BSc Honours students. Third, it will generate new knowledge about genome recombination in animal mitochondria. Recombination is a fundamental, yet poorly understood issue in mitochondrial genomics and evolutionary biology. Knowledge from this project will also improve our understanding of other important issues that are associated with animal mitochondria; like the mechanisms of mitochondrial disease and ageing, and the evolution of modern humans and other animals.Read moreRead less
Antibiotic resistance is a looming public health crisis. New antibiotics with new mechanisms of action are desperately needed. The long-term goal of this research is to develop new drugs that disarm bacteria to overcome the problem of antibiotic resistance.
A community based social identity approach to loneliness. Loneliness across Australia is a deep concern. Social prescribing is a novel community-based approach to managing loneliness, however it is unclear when and in what circumstances it is effective. This project aims to test a social identity approach to loneliness, incorporating longitudinal, cross-sectional, and experimental methods to understand how best to engage isolated people in group programs. The expected benefits of this project ar ....A community based social identity approach to loneliness. Loneliness across Australia is a deep concern. Social prescribing is a novel community-based approach to managing loneliness, however it is unclear when and in what circumstances it is effective. This project aims to test a social identity approach to loneliness, incorporating longitudinal, cross-sectional, and experimental methods to understand how best to engage isolated people in group programs. The expected benefits of this project are to produce a validated social prescribing model that can be implemented in multiple settings across Australia in order to reduce loneliness, strengthen communities, and guide more appropriate uses of health services.Read moreRead less
Identifying Novel Long-noncoding RNAs Involved In The Development Of Breast Cancer

Funding Amount
$785,204.00
Summary
Recent studies have identified regions within the human genome in which DNA sequence variations are associated with an increased risk of breast cancer. The aim of this proposal is to identify and characterise these non-coding genes that are modulate breast cancer risk. Understanding how sequences variations that alter these novel genes contribute to breast cancer will provide novel avenues for therapy.
Organisation, expression and diversity of the sub-telomeric regions of the ancient eukaryote, Giardia duodenalis. We propose to extend our findings on the extreme plasticity of the structure and organisation of the sub-telomeric region of the complete genome of Giardia by more extensive chromosome walking, and comparison of different isolates. These regions are subject to gene conversion, transcriptional silencing, gene mobility, recombination, variable surface protein expression, subtelomeric i ....Organisation, expression and diversity of the sub-telomeric regions of the ancient eukaryote, Giardia duodenalis. We propose to extend our findings on the extreme plasticity of the structure and organisation of the sub-telomeric region of the complete genome of Giardia by more extensive chromosome walking, and comparison of different isolates. These regions are subject to gene conversion, transcriptional silencing, gene mobility, recombination, variable surface protein expression, subtelomeric instability and the insertion of transposable elements, a dynamic balance between structural conservation and rapid evolution. This is a rare opportunity to understand the forces at work in moulding eukaryotic sub-telomeric sequences because Giardia is not constrained by sexual homogenisation and the dynamic variability is retained.Read moreRead less
Structural And Functional Analysis Of A Cancer-linked Co-regulator Complex

Funding Amount
$729,571.00
Summary
We seek to understand the mechanisms by which genes are switched on and off throughout our lifetime. A number of multi-component protein machines are involved in this process but their make-up and mechanism of action is not understood. We will investigate the structure and function of one of these machines that has been strongly linked to cancer.
