Funding Amount

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.
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.
Functional Analysis Of Breast Cancer Susceptibility Regions

Funding Amount
$790,588.00
Summary
Recent studies have identified regions within the human genome in which DNA sequence variations are associated with an increased risk of breast cancer. Several of these regions do not contain any known genes, suggesting that regulatory DNA sequences are responsible for the associated risk. The aim of this proposal is to identify and characterise these DNA sequences. Understanding how sequences variations in these regions contribute to breast cancer will provide novel avenues for therapy.

Understanding how eukaryotic cells work is a major goal of 21st century biology. A crucial step will be to catalogue the functional components of eukaryotic genomes. Australian researchers must be involved in this process at an early stage, in order to maximise commercial opportunities, attract quality researchers and position ourselves for further advances. This project will make major contributions to international efforts in this area, via the development of statistical methods for segmenting genomes, classification of those segments, and study of the resulting classes. In the long term, enhanced understanding of eukaryotic cells will lead to breakthroughs in biology, and to medical, pharmaceutical, agricultural and scientific advances.Read moreRead less
Enhancing wellbeing over the family life course. This project aims to investigate the impact of family life transitions, such as relationship formation and dissolution or births, on wellbeing over the life course. It will do this by analysing data following people over time and will provide information about the negative and positive effects of family transitions for wellbeing, track changes in wellbeing before, during and after transitions, and highlight the intersections of the family life cou ....Enhancing wellbeing over the family life course. This project aims to investigate the impact of family life transitions, such as relationship formation and dissolution or births, on wellbeing over the life course. It will do this by analysing data following people over time and will provide information about the negative and positive effects of family transitions for wellbeing, track changes in wellbeing before, during and after transitions, and highlight the intersections of the family life course with gender, age and socioeconomic status. This will considerably enhance understandings of wellbeing over the family life course, providing insights for targeted policies and interventions to improve health and wellbeing.Read moreRead less
