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.
Prion-like Behaviour In Immunity: Super-sized Signalling Platforms?

Funding Amount
$611,995.00
Summary
Prions have been mostly associated with pathologies but recent discoveries show that prion-like behaviour may be beneficial, enhancing our immune response for example. To test this, we want to systematically explore all human proteins involved in the defence against pathogens, find new prion-like trends and probe their role in the innate immune response.
Many drugs modulate the function of proteins imbedded in cell membranes. Extensive research has been undertaken to better understand drug interactions with these proteins to improve drug therapies, but there has been relatively little progress in understanding the role of the cell membrane. This project will investigate how the cell membrane influences protein function and then use this information to develop novel drugs for the treatment of neurological disorders.

Biomolecular research and research training, in which proteomics is core, has become a critical component of post-industrial development in the Hunter region. Development of a cutting edge proteomics facility will benefit a research community comprising over 50 researchers and 150 undergraduate students significantly enhancing their research productivity and translation of outcomes in areas of national importance. These include understanding the impact of the environment on plant and animal development, pest animal control, development of new biotechnology tools, new drugs and new methods for the detection of narcotics and explosives.Read moreRead less
Determination of the mechanisms of immune system regulation of inflammation by the human protein, chaperonin 10. The aim of this project is to determine the mechanisms by which a human protein, chaperonin 10 (Cpn10), regulates the immune system and suppresses inflammation. When cells of the human immune system are challenged with lipopolysaccharide (LPS) (a product of bacterial infection), the pro-inflammatory cytokine TNF is released. Cpn10 has been shown to suppress production of TNF on chall ....Determination of the mechanisms of immune system regulation of inflammation by the human protein, chaperonin 10. The aim of this project is to determine the mechanisms by which a human protein, chaperonin 10 (Cpn10), regulates the immune system and suppresses inflammation. When cells of the human immune system are challenged with lipopolysaccharide (LPS) (a product of bacterial infection), the pro-inflammatory cytokine TNF is released. Cpn10 has been shown to suppress production of TNF on challenge of cells with LPS, while increasing the levels of the anti-inflammatory cytokine IL-10. Investigating the role of Cpn10 in modulating inflammation will contribute to the understanding and treatment of diseases associated with inflammation, including multiple sclerosis and rheumatoid arthritis.Read moreRead less

Nuclear Trafficking of Apolipoprotein-E. Apolipoprotein-E (apoE) regulates specific age-related neurodegenerative and cardiovascular diseases. The role of apoE in these disorders is unclear. This project will benefit our community by providing the basic cell biology knowledge required to understand disease mechanisms and ultimately provide avenues for better treatments.

Apolipoprotein-E (apoE) regulates specific age-related neurodegenerative and cardiovascular diseases. The role of apoE in these disorders is unclear. This project will benefit our community by providing the basic cell biology knowledge required to understand disease mechanisms and ultimately provide avenues for better treatments. Aspects of the project will focus on the modification of apoE by carbohydrates and the interaction of apoE with cellular carbohydrate-containing structures. The importance of carbohydrates in the regulation of cellular and protein function is increasingly recognised and forms a foundation for the rapidly expanding discipline of glycobiology. This project will strengthen Australia's glycobiology research capacity.Read moreRead less
The Role Of Nuclear Architecture In The DNA Damage Response

Summary
The goal of the proposed research is to understand how dynamic changes to the chromatin genome packaging network, interact with the DNA damage response and gene expression machinery, to repair damaged DNA and the impact this has on cancer biology. To do so we are combining cutting edge molecular biology techniques with innovative novel microscopy methods developed by our research team, that far exceed the spatiotemporal resolution currently used to study chromatin biology.
