Summary
Hepcidin is a peptide hormone that is a major regulator of iron metabolism. It has been suggested that hepcidin is free in the blood. However, we recently identified that hepcidin binds with alpha-2-macroglobulin (a2-M) in the plasma and this increases the efficacy of this peptide. The demonstration that a2-M plays a role in hepcidin biology will lead to a better understanding of hepcidin physiology, the development of methods for its measurement and improved treatment of iron related diseases.
Discovery And Mechanisms Of Host Cell Factors In HIV Uncoating

$635,098.00
Summary
HIV entry into the host cell involves release of its capsid, a protein shell protecting the viral genome. The capsid hijacks host proteins to cloak itself from cellular defenses while the cell has evolved sensors that can block viral infection. This proposal aims to discover proteins involved in this arms race between host and virus and decipher how they control capsid disassembly. This insight will help design new drugs against HIV infection and new ways to deliver genes for gene therapies.
Structural And Functional Studies On RNA Nuclear Retention Mediated By Paraspeckles: A Novel Gene Regulation

Funding Amount

Summary
Dynamic interactions between proteins and nucleic acids are essential process in gene regulation, where aberrant regulation leads to various diseases including cancers. The project aims to examine the interactions between paraspeckle proteins and nucleic acid molecules via determination of the structures of protein-nucleic acid complexes at the atomic level. The results will provide a better understanding of a recently discovered gene regulation mechanism and a basis for new gene therapy.
Glycine Transporters regulate the concentration of glycine in the spinal cord and brain. It has been suggested that elevating glycine levels in these regions may be useful in treating pain and schizophrenia. This project will provide the basis for the development of new glycine transport inhibitors that may be used to treat these conditions.
Role Of IGF Binding Protein-3 (IGFBP-3) And IGFBP-5 As Modulators Of Nuclear Hormone Signalling

Summary
The insulin-like growth factors are small proteins involved in the growth of most tissues. Their actions are regulated by binding to larger proteins (known as IGFBPs) in the bloodstream and outside the cell. However, some IGFBPs are also found inside cells, where they seem to carry out other functions. We believe that two of these binding proteins, IGFBP-3 and IGFBP-5, change the way cells respond to vitamin A and vitamin D.

Their actions are regulated by binding to larger proteins (known as IGFBPs) in the bloodstream and outside the cell. However, some IGFBPs are also found inside cells, where they seem to carry out other functions. We believe that two of these binding proteins, IGFBP-3 and IGFBP-5, change the way cells respond to vitamin A and vitamin D. These two vitamins are important in cell growth and in the way certain cells perform specialised functions. In test-tube experiments, IGFBP-3 and IGFBP-5 interact directly with the receptors that regulate the effects of these hormones. If the same thing happens inside the cell, IGFBP-3 and IGFBP-5 could change the way these receptors respond to signals from outside the cell. We will investigate what effect these IGFBPs have in living cells and in whole animals and how this may relate to human disease. If we are able to understand how IGFBP-3 and IGFBP-5 affect the way cells respond to vitamin A and D, then we may be able to develop new ways to treat certain human diseases.Read moreRead less
Mobile Indonesians: social differentiation and digital literacies in the twenty first century. This is the first dedicated study of the social implications of mobile telephony's recent and rapid popularisation throughout the country. This project will study metropolitan, urban and rural users to understand how mobile phones create the new and unexpected social networks which will shape tomorrow's Indonesians.
Domestic Subversions: maternalism and cross-cultural histories. This project will assist in the processes of reconciliation, by fostering a sense of a shared history, and increasing public awareness of the complexity of race relations histories in Australia. It will redress a significant gap in Australian knowledge and literature. Very little is known about the history of Aboriginal domestic workers and their relationships with their white employers in Australia, despite growing awareness of the ....Domestic Subversions: maternalism and cross-cultural histories. This project will assist in the processes of reconciliation, by fostering a sense of a shared history, and increasing public awareness of the complexity of race relations histories in Australia. It will redress a significant gap in Australian knowledge and literature. Very little is known about the history of Aboriginal domestic workers and their relationships with their white employers in Australia, despite growing awareness of the significance of domestic service in Aboriginal child removal policies. The project will also assist in establishing Australian historical scholarship at the forefront of leading international research initiatives in gender, race and colonialism studies.

Autobiography of a People: Aboriginal Writing in Queensland, 1890s-1930s. As the recent "history wars" confirm, Australians today care deeply about the colonial past, because its legacies are "all around us and within" (as Oodgeroo noted). This project advances knowledge and conceptual understanding in the key areas of colonial race relations, Indigenous self-representation, and Indigenous literacy.

As the recent "history wars" confirm, Australians today care deeply about the colonial past, because its legacies are "all around us and within" (as Oodgeroo noted). This project advances knowledge and conceptual understanding in the key areas of colonial race relations, Indigenous self-representation, and Indigenous literacy. Aboriginal autobiography is an especially effective tool for stimulating the empathetic imagination, and bridging social, temporal and geographical distances between people. This research will strengthen the nation's social fabric by promoting inter-racial understanding, and by adding historical depth to present thinking about contemporary Aboriginal attitudes to literacy.Read moreRead less
Creativity and cultural production in the Hunter: an applied ethnographic study of new entrepreneurial systems in the creative industries. This project will be an applied study of key collaborative groups across all the major creative industries in the Hunter region in New South Wales. Mapping these industries' approach to creativity and cultural production in the digital realm will provide detailed insights into the dynamic systems at the heart of creative industries.
Cultural Research for the 21st Century: Building Cultural Intelligence for a Complex World. This project will advance our knowledge of the complex cultural challenges facing 21st century Australia, and how these challenges can be addressed through engaged cultural research.

This project will advance our knowledge of the complex cultural challenges facing 21st century Australia, and how these challenges can be addressed through engaged cultural research. It will promote cultural innovation by enabling public institutions to develop effective responses to the increasing complexity of their operating environments, especially in light of society's proliferating cultural diversity. The project will expand the national innovation system by building the capacity of cultural researchers (and humanities and social science researchers more generally) to conduct collaborative and interdisciplinary research that contributes to the solution of important social and cultural problems.
