Natural Treg are dependent on the transcription factor FOXP3, but the mechanism of action of FOXP3 is only now becoming defined for human Treg. Tregs are critical for a balanced, responsive immune system, and deviation from this balance results in autoimmune diseases or persistence of cancers. In order to intervene to treat these disease it is essential to first know what makes a normal Treg function, and to then compare this with the disease so that faulty genes can be targeted for intervention ....Natural Treg are dependent on the transcription factor FOXP3, but the mechanism of action of FOXP3 is only now becoming defined for human Treg.

Inferring Global Regulatory Architecture Of Human Gene Expression In Health And Disease
Funder

Funding Amount
$47,427.00
Summary
Our genome encodes ~25,000 genes that shape out an individual from head to toe. Malfunction of a particular gene could cause fatal health problem or disease. Nonetheless, the mis-regulation of functioning genes can also result in serious diseases. In this study, we are going to use large-scale gene regulation information and advanced computing techniques to clarify the regulation network of human genome on a global level. Hence, helping us to understand more about diseases of gene transcription.
The Molecular Function And Role Of The New Metastasis Suppressor NDRG1 In Cancer

Funding Amount
$226,425.00
Summary
With cancer now a leading cause of death in Australia, finding new ways to treat this disease is crucial. Iron is critical for cancer cell growth and metastasis, thus agents that bind iron (called iron chelators) can be used to treat cancer. These drugs up-regulate the gene NDRG1, which has been shown to prevent tumour spread. The role of NDRG1 in tumour growth and spread of cancer cells will be examined as this may lead to novel therapies against cancer (e.g. the use of novel iron chelators).
An Integrative Structural Biology Approach To Understanding The SAGA Transcriptional Master Regulator Implicated In Cancer And Development

Funding Amount
$318,768.00
Summary
Stringent control of gene expression ensures the harmonious life of all human cells. Loss of this control leads to development of a chaotic genome, characteristic of diseased states such as cancer. In this proposal, we aim at capturing and understanding the first key steps of the mechanism that, if dysfunctional, leads to aberrant gene expression. We will use cutting-edge structural bio-imaging to answer questions of fundamental importance to human health and pathologies.
Identifying Novel Molecular Targets For Treating Chronic Pain.

Funding Amount
$402,952.00
Summary
Chronic pain is very common, with one in five Australians suffering long-term pain that is serious enough to cause disability. It is extraordinarily difficult to treat. Medicines used to treat normal pain symptoms are usually ineffective on chronic pain patients because the cause of the pain is different. The aim of this project is to identify new drug targets in the spinal cord that are specific for chronic pain so we can develop new medicines to reverse the symptoms safely and effectively.
Mechanistic And Functional Analysis Of The Id4 Proto-oncogene In Breast And Ovarian Cancer
Funder

Funding Amount
$693,983.00
Summary
Cancer arises through damage to normal regulatory processes in cells. Understanding these damaged processes is essential to implement personalized medicine. This proposal explores the role of the proto-oncogene ID4 in the closely related cancers triple negative breast cancer and serous ovarian cancer. This research may lead to the development of new therapeutic strategies or the refinement of existing strategies for these poor prognosis cancers.
