Summary
An in situ structural study of Drosophila embryonic patterning. This project aims to develop and deploy an in situ structural biology approach, which enables direct visualisation of large macromolecular structures in cells, to be used in combination with molecular genetics, proteomics and computational biology. In situ structural biology has the potential to revolutionise discovery across life science, providing direct insight into macromolecular structure and function. This project will establi ....An in situ structural study of Drosophila embryonic patterning. This project aims to develop and deploy an in situ structural biology approach, which enables direct visualisation of large macromolecular structures in cells, to be used in combination with molecular genetics, proteomics and computational biology. In situ structural biology has the potential to revolutionise discovery across life science, providing direct insight into macromolecular structure and function. This project will establish the field of in situ structural biology in Australia by studying how a model organism, the fruit fly Drosophila melanogaster controls the development of how the head and tail of the embryo are specified. The project will further develop new instrumentation and approaches that will bring in situ biology to the wider scientific community.Read moreRead less
Awaking quiescent neural stem cells. This project aims to generate new knowledge in the area of the evolutionary size of animals and plants, which is determined by intrinsic cell regulation and is constrained by nutrient availability. Brain size is perhaps the most profound example of this. Brain size regulation is underpinned by control of proliferation of neural stem cells (NSCs). Using Drosophila NSCs, the project will examine how nutrients impact on NSC quiescence versus activation, a key ch ....Awaking quiescent neural stem cells. This project aims to generate new knowledge in the area of the evolutionary size of animals and plants, which is determined by intrinsic cell regulation and is constrained by nutrient availability. Brain size is perhaps the most profound example of this. Brain size regulation is underpinned by control of proliferation of neural stem cells (NSCs). Using Drosophila NSCs, the project will examine how nutrients impact on NSC quiescence versus activation, a key characteristic of stem cell control throughout evolution. This will increase our understanding of how energy metabolism and nutrition influence organ size control in multicellular organisms, by determining how organs communicate with each other to convert nutrient signals to action stem cell proliferation.Read moreRead less
Control of developmental switches by importin 5. Aims: This project will study a key molecular switch called IPO5, a protein that is required for cells and organs to form and function normally, and it will reveal how it works.
Significance: These experiments will provide the first complete description of how this molecular switch controls the behaviour of a cell across its lifespan. IPO5 is highly conserved, so these studies will be relevant to a wide range of animals.
Expected Outcomes: This k ....Control of developmental switches by importin 5. Aims: This project will study a key molecular switch called IPO5, a protein that is required for cells and organs to form and function normally, and it will reveal how it works.
Significance: These experiments will provide the first complete description of how this molecular switch controls the behaviour of a cell across its lifespan. IPO5 is highly conserved, so these studies will be relevant to a wide range of animals.
Expected Outcomes: This knowledge will reveal how IPO5 controls formation of sperm by revealing what other proteins it binds to and how this affects cell signaling and responses to the environment.
Benefits: This will provide information about potential interventions to control fertility or to repair abnormal cells.

Cell death by self-eating: Autophagy-dependent tissue removal. This project aims to study the mechanisms and regulation of autophagy-dependent cell death. Cell death maintains cell and tissue homeostasis. Although most cell death is mediated by apoptosis, other modes of cell deletion have emerged recently. One form of cell death involves autophagy, the catabolic process of cellular self-digestion through lysosomal enzymes. As autophagy is a default mechanism of cell survival under stress, the id ....Cell death by self-eating: Autophagy-dependent tissue removal. This project aims to study the mechanisms and regulation of autophagy-dependent cell death. Cell death maintains cell and tissue homeostasis. Although most cell death is mediated by apoptosis, other modes of cell deletion have emerged recently. One form of cell death involves autophagy, the catabolic process of cellular self-digestion through lysosomal enzymes. As autophagy is a default mechanism of cell survival under stress, the idea of autophagy-dependent cell death has been controversial. This proposal aims to resolve this question and provide highly topical knowledge of broad biological significance.Read moreRead less
Formation of boundaries in the developing embryo. This project aims to decipher how the boundaries between the different organs are established in the developing embryo. The project aims to identify the components of the gene regulatory network that controls lateral plate mesoderm formation, develop a mathematical model that can explain how the domains are formed within this region, and validate novel interactions in vivo in zebrafish. The expected outcome of the project is to reveal how the pro ....Formation of boundaries in the developing embryo. This project aims to decipher how the boundaries between the different organs are established in the developing embryo. The project aims to identify the components of the gene regulatory network that controls lateral plate mesoderm formation, develop a mathematical model that can explain how the domains are formed within this region, and validate novel interactions in vivo in zebrafish. The expected outcome of the project is to reveal how the progenitors of our body parts are instructed to be positioned at the right time and at the right place in the embryo. This project should provide significant benefit such as the expansion of Australia's knowledge base and research capability in cross-disciplinary science.Read moreRead less
Metabolic control of organ growth and regeneration. One of the fundamental questions in biology is to understand how organ size is regulated at the cellular and organismal level. The Hippo/Yap pathway plays a central role in the regulation of organ size and it is impacted by environmental cues including nutrient status. This research proposal aims to use zebrafish to elucidate the role that the Hippo/Yap pathway plays in reprogramming lipid metabolism to fuel tissue growth in development and reg ....Metabolic control of organ growth and regeneration.

The Hippo/Yap pathway plays a central role in the regulation of organ size and it is impacted by environmental cues including nutrient status. This research proposal aims to use zebrafish to elucidate the role that the Hippo/Yap pathway plays in reprogramming lipid metabolism to fuel tissue growth in development and regeneration. Ultimately, this work aims to identify metabolic dependencies required for organ growth and regeneration. Expected outcomes include scholarly publications revealing fundamental principles underlying tissue growth, new resources for the research community and training for research students.Read moreRead less
Understanding self-organising tissues. This project will discover how an organ can form from a mixture of component cells by 'self-organisation'. Understanding of how this can occur, could potentially be applied to the bioengineering of organs from component cells.
A novel DNA damage repair protein as a regulator of DNA double strand break repair and genome integrity. This project aims to define the function of a novel DNA damage repair protein. These data will provide a better understanding of DNA repair biology and may reveal novel diagnostic and treatment options for many diseases associated with DNA repair defects, including cancer.
Role of Musashi in the regulation of cell cycle proteins. We have identified a protein family that directs cell fate and maintains male fertility. This project will provide new avenues for generation of contraceptives in male animals and to regulate stem cells for production of specialised cell types in biotechnological applications.
