Differential roles of gene family members in development of a cell lineage. This project aims to investigate how a family of genes influence cells in the testis to become mature sperm. Testicular cells regulate gene activity via the Snail family of proteins during sperm development, and interruption of their activities reduces fertility in mice and fruit flies. The project aims to use genetic, cell biological and biochemical studies in Drosophila and mice to compare different Snail family protei ....Differential roles of gene family members in development of a cell lineage. This project aims to investigate how a family of genes influence cells in the testis to become mature sperm. Testicular cells regulate gene activity via the Snail family of proteins during sperm development, and interruption of their activities reduces fertility in mice and fruit flies. The project aims to use genetic, cell biological and biochemical studies in Drosophila and mice to compare different Snail family proteins in spermatogenesis. The outcomes will define the different roles of highly similar proteins from the same family in differentiation of a single cell lineage. This is important in generating functional tissues using in vitro laboratory approaches or understanding how normal development and developmental disorders arise.Read moreRead less
Understanding the potency and role of individual stem cells in the skin using Rainbow technology. To renew itself, the skin and its components rely on the activity of stem cells. This project will define more precisely the role of each individual stem cell by labelling them with a unique colour and following its fate. This project has the potential to change our current view on how the skin maintains and repairs itself.
Targeting mitochondria with mitocans to treat cancer: mechanistic aspects. Mitochondria are the power-house of the cell and also the reservoir of proteins causing the demise of cancer cells, therefore suppressing tumour progression. This project proposes a novel way to modify certain compounds, increasing their level in mitochondria in order to maximise their anti-cancer effect.
Mechanism and function of cell asymmetry during cell death. This project aims to investigate how dying cells rearrange their cellular contents to aid their removal.
More than 200 billions cells die daily in the human body. It is critical that dying cells are rapidly cleared as their buildup can interfere with normal tissue functions. This project will use a suite of contemporary molecular/cell biological approaches to study a newly identified process that occurs during cell death. Expected outc ....Mechanism and function of cell asymmetry during cell death. This project aims to investigate how dying cells rearrange their cellular contents to aid their removal.
More than 200 billions cells die daily in the human body. It is critical that dying cells are rapidly cleared as their buildup can interfere with normal tissue functions. This project will use a suite of contemporary molecular/cell biological approaches to study a newly identified process that occurs during cell death. Expected outcomes include a paradigm-shift in understanding the process of cell clearance.
This project is expected to generate fundamental new knowledge of the mechanisms by which dying cells are efficiently removed from tissues. This should provide significant benefits to the cell death and general cell biology fields.Read moreRead less
The lipidomics of cell fate. This project aims to dissect the roles of lipids in cell fate. The study of lipids, or lipidomics, is an emerging and exciting area of biological science. The fundamental roles of lipids in development remain vastly understudied. This project will look at reprogramming of somatic cells into stem cells, their pluripotency and differentiation. This will be complemented with studies in the zebrafish, which permits the direct study of cell fate in vivo. This approach is ....The lipidomics of cell fate.

This will be complemented with studies in the zebrafish, which permits the direct study of cell fate in vivo. This approach is a powerful way to unlock major events involved in development and to unmask the roles of lipids in these fundamental mechanisms.Read moreRead less
Mechanism and function of dying cell disassembly. This project aims to elucidate the molecular machinery that disassembles dying cells, and the role of this process in cell clearance. Billions of cells in the body die daily as part of normal turnover. Dying cells must be rapidly removed, as their accumulation can interfere with normal tissue functions. To efficiently clear dead cells, dying cells can disassemble into smaller fragments that neighbouring cells engulf. Understanding the mechanistic ....Mechanism and function of dying cell disassembly. This project aims to elucidate the molecular machinery that disassembles dying cells, and the role of this process in cell clearance. Billions of cells in the body die daily as part of normal turnover. Dying cells must be rapidly removed, as their accumulation can interfere with normal tissue functions. To efficiently clear dead cells, dying cells can disassemble into smaller fragments that neighbouring cells engulf. Understanding the mechanistic basis and function of dying cell disassembly is expected to generate knowledge of the downstream consequence of cell death. This breakthrough will be important in many fields of research including cell biology and biochemistry, and generate basic knowledge that can ultimately be applied in medical science to understand or treat pathological conditions associated with cell death.Read moreRead less
Mechanisms by which Beclin1 regulates intestinal homeostasis. This project aims to investigate if Beclin1, a protein which has an important and well-accepted role in promoting cell survival through the program of autophagy, has an alternate job mediating trafficking within a cell. Using novel mouse models and innovative techniques, the project aims to demonstrate the physiological importance of this alternate role for Beclin1. Expected outcomes include enhancing Australia's international researc ....Mechanisms by which Beclin1 regulates intestinal homeostasis.

Unravelling the holistic genetic control of vertebrate development. Understanding the genetic regulation of embryo formation is the cornerstone of developmental biology. As four per cent of Australian children are born with some form of prenatal defect, understanding the basic biology of embryogenesis is paramount for long-range development of future therapies. We have identified a highly conserved transcription factor, Grhl3, which regulates multiple stages of embryonic formation.

As four per cent of Australian children are born with some form of prenatal defect, understanding the basic biology of embryogenesis is paramount for long-range development of future therapies. We have identified a highly conserved transcription factor, Grhl3, which regulates multiple stages of embryonic formation. Using advanced genetic models, this project will characterise the role of Grhl3 in the regulation of cellular migration and craniofacial skeleton and brain development. The project will also identify the target genes which Grhl3 regulates. The identification of such transcriptional networks is imperative to understanding the holistic molecular control of embryogenesis.Read moreRead less
