Summary
Alterations in NOD signalling have been implicated in various human inflammatory diseases, particularly in Crohn’s disease and asthma. In this project we will identify new molecules that regulate NOD signalling and test the effect of drugs that inhibit known components of these pathways to determine their utility in treating inflammatory diseases.
Protein Kinase Regulatory Switches: Decision-Making in the Nucleus. This project plans to examine new regulatory mechanisms for an important signalling enzyme in the cell nucleus. It aims to define how this enzyme enters the nucleus, to characterise new modifications that affect its actions, and to establish how a conserved nuclear protein may provide an unexpected regulatory platform to send nucleus-initiated signals back to the cell cytoplasm. This reverse signalling is a novel mechanism for i ....Protein Kinase Regulatory Switches: Decision-Making in the Nucleus. This project plans to examine new regulatory mechanisms for an important signalling enzyme in the cell nucleus. It aims to define how this enzyme enters the nucleus, to characterise new modifications that affect its actions, and to establish how a conserved nuclear protein may provide an unexpected regulatory platform to send nucleus-initiated signals back to the cell cytoplasm. This reverse signalling is a novel mechanism for integrating nuclear actions that has the potential to create a signal transduction circuit triggered by environmental or genetic factors. This information is crucial in defining the molecular logic of signalling events that may be ultimately targeted to control cell growth, differentiation and survival.Read moreRead less

Summary
Estrogen-mediated regulation of gene expression via transcriptional and translational control: complementary, synergistic or opposing responses? Hormones dictate cellular behaviour by activating pre-programmed responses. The sex hormone estrogen affects cell fate by regulating the gene expression, but it is unknown to which extent this response occurs via activation of genes or control of already transcribed gene. The project will investigate how the cell integrates the complex estrogen signals.
The Hippo signalling pathway in dividing and non-dividing cells. This project aims to understand how the Drosophila Hippo pathway performs two very different jobs in the same organ, that is control cell proliferation and differentiation. The redeployment of cellular machinery to do different jobs is very common and efficient, but the mechanism by which this occurs is poorly understood. Using new techniques, this project aims to provide new knowledge to several fields including organ growth contr ....The Hippo signalling pathway in dividing and non-dividing cells. This project aims to understand how the Drosophila Hippo pathway performs two very different jobs in the same organ, that is control cell proliferation and differentiation. The redeployment of cellular machinery to do different jobs is very common and efficient, but the mechanism by which this occurs is poorly understood. Using new techniques, this project aims to provide new knowledge to several fields including organ growth control, cell fate specification, cellular signalling and eye vision. These discoveries are likely to enhance international collaborations and stimulate new research.Read moreRead less
Transcription factor nuclear residency as a driver of gene expression. Persistently active proteins can stay in the nucleus to drive cell growth and prevent cell death. This project will define how one specific active protein can remain in the nucleus and regulate gene expression through the action of unique ribonucleic acid (RNA) molecules. The results will enable persistent gene activation to be manipulated in cancer.
Programmed cell death signalling in innate immunity. This proposal aims to address the under-explored potential for programmed cell death to promote innate immune cell signalling, which is a critical and fundamental biological process. It aims to generate new knowledge in the areas of cell death and innate signalling using innovative interdisciplinary approaches and discover new molecules that impact innate inflammatory responses. The expected outcomes of this project are to enhance our basic un ....Programmed cell death signalling in innate immunity. This proposal aims to address the under-explored potential for programmed cell death to promote innate immune cell signalling, which is a critical and fundamental biological process. It aims to generate new knowledge in the areas of cell death and innate signalling using innovative interdisciplinary approaches and discover new molecules that impact innate inflammatory responses. The expected outcomes of this project are to enhance our basic understanding of cell death, and build interdisciplinary collaborations. This work should provide significant benefit to the economy and health of Australians, as it is expected to identify molecules that will be of interest to the pharmaceutical and biotechnology industries.Read moreRead less
The role of a novel protein, interferon epsilon, in reproductive tract immunity. This project aims to develop a world-first description of a new protein that has a protective role against female reproductive tract infections. This unique protein, called interferon epsilon, was discovered in our laboratory. This project will facilitate development of new therapeutic approaches of benefit in diseases such as Chlamydia and Herpes Simplex Virus.
