Understanding how cells compact and segregate DNA in vertebrates. How a cell compacts and divides its DNA is still a major unanswered question in biology. This project will determine the way in which a cell compacts its DNA nearly ten thousand fold to allow the faithful and accurate segregation to daughter nuclei.
Unraveling the genetic networks of cancer development. Cancer causes nearly 30% of all deaths in Australia and the aging of our population means that its incidence will increase for the foreseeable future. The past two decades of cancer research have yielded great advances in identifying the genetic mutations that contribute to cancer, but our understanding of how these mutations cooperate to transform a healthy cell into a tumour cell remains limited. High-throughput genomic analysis of DNA fro ....Unraveling the genetic networks of cancer development. Cancer causes nearly 30% of all deaths in Australia and the aging of our population means that its incidence will increase for the foreseeable future. The past two decades of cancer research have yielded great advances in identifying the genetic mutations that contribute to cancer, but our understanding of how these mutations cooperate to transform a healthy cell into a tumour cell remains limited. High-throughput genomic analysis of DNA from large numbers of tumours is essential to identify and understand the combinations of cancer mutations that are most deadly. Such studies can form the basis for developing better diagnostics and new treatments for patients whose tumours are resistant to current therapies.Read moreRead less
The effect of mitochondrial and nuclear-cytoplasmic variation on longevity, metabolism and stress resistance in Drosophila. Much research points to a major role of free radical damage in aging, thus the belief that antioxidants might be beneficial in delaying aging. Free radicals are mostly formed in the subcellular organelles which consume oxygen and produce energy, and this may be the major site of age-related damage. This project seeks to understand the degree to which variation among these ....The effect of mitochondrial and nuclear-cytoplasmic variation on longevity, metabolism and stress resistance in Drosophila.

Free radicals are mostly formed in the subcellular organelles which consume oxygen and produce energy, and this may be the major site of age-related damage. This project seeks to understand the degree to which variation among these subcellular organelles affect free radical damage and aging, using the fruitfly Drosophila melanogaster as a model organism.Read moreRead less

Summary
The dynamic interplay between the matrix and cell fate in developing heart. Malformations in the developing heart can lead to catastrophic defects and embryonic loss. The valves play a critical role in blood flow regulation and are made of a stratified matrix that is laid down early in development. This project aims to determine how the cellular fate of the early valve cells establish the layered matrix and in turn how the matrix can influence cell fate by utilising a multi-omics approach to ide ....The dynamic interplay between the matrix and cell fate in developing heart. Malformations in the developing heart can lead to catastrophic defects and embryonic loss. The valves play a critical role in blood flow regulation and are made of a stratified matrix that is laid down early in development. This project aims to determine how the cellular fate of the early valve cells establish the layered matrix and in turn how the matrix can influence cell fate by utilising a multi-omics approach to identify unique cell populations and integrate transcriptional and protein changes during matrix disruption. This project expects to generate fundamental knowledge on how matrix structure can influence cell fate in the valves and will advance Australia's knowledge base and research capabilities in developmental biology.Read moreRead less
The genetic regulation of organogenesis: endoderm development in the Drosophila embryo. Embryonic development is an important research field in biology, not only for its extraordinary complexity but also because of the insights it provides into molecular processes that underpin a variety of diseases. This project aims to discover genes and molecules that regulate the normal development of one of the most important organs, the gut.
How does Fat cadherin control organ size in Drosophila, and cancer in humans? The primary function of Fat cadherin is to dictate the appropriate size of organs in developing animals. Deficiency in the fat gene results in vastly overgrown organs and can lead to the formation of cancer in humans. Our study will provide important insights into how the size of organs are controlled during development. Our research findings will have important implications for several aspects of human health and biol ....How does Fat cadherin control organ size in Drosophila, and cancer in humans? The primary function of Fat cadherin is to dictate the appropriate size of organs in developing animals. Deficiency in the fat gene results in vastly overgrown organs and can lead to the formation of cancer in humans. Our study will provide important insights into how the size of organs are controlled during development. Our research findings will have important implications for several aspects of human health and biology, and will increase our understanding of diseases that arise due to aberrant tissue growth, such as cancer. Our research findings will thus be of substantial national benefit, given that cancer is now the biggest cause of death in Australia, and that more than 88,000 Australians are diagnosed with cancer each year.

Characterisation of heavy metal transport genes in the plant Arabidopsis: potential roles in metal detoxification and accumulation. Plants have considerable potential for the bioremediation ("phytoremediation") of contaminated soils, including soils polluted with heavy metals.

Plants have considerable potential for the bioremediation ("phytoremediation") of contaminated soils, including soils polluted with heavy metals. Progress has been made in understanding the physiological and biochemical mechanisms by which plants accumulate and detoxify heavy metals. One important aspect of metal detoxification is the transport of metals across cell membranes. The recently completed genome project for the model plant Arabidopsis has identified a family of genes encoding heavy metal transport proteins. This project aims to investigate the roles of these genes in metal detoxification. In the longer term this knowledge can be applied to the improvement of phytoremediation processes.Read moreRead less
Mechanisms of zinc transport and homeostasis in the plant, Arabidopsis. Zinc-deficiency is one of the most widespread factors limiting crop production and affects many soils of south-east and south-west Australia. Certain zinc-efficient (ZE) crop cultivars are able to grow well under zinc deficient conditions but the genetic basis for ZE is not well understood.

Zinc-deficiency is one of the most widespread factors limiting crop production and affects many soils of south-east and south-west Australia. Certain zinc-efficient (ZE) crop cultivars are able to grow well under zinc deficient conditions but the genetic basis for ZE is not well understood. Using a model organism such as Arabidopsis to identify genes in plants that are important in zinc transport and homeostasis will ultimately allow us to assess whether the homologous genes in crop species are responsible for ZE. This may contribute to more rapid and directed strategies in breeding ZE crop cultivars.Read moreRead less
Understanding how the heart becomes more efficient. The body demands that the heart function at utmost efficiency. Trabeculae – folds within the heart lumen – maximise blood flow, contribute to chamber development and form the electrical conduction network of the heart.

The body demands that the heart function at utmost efficiency. Trabeculae – folds within the heart lumen – maximise blood flow, contribute to chamber development and form the electrical conduction network of the heart. Problems with trabeculae formation cause cardiomyopathy and arrhythmia and yet we do not understand its basic development. The project will investigate the earliest stages of when this tissue develops its identity and examine the signalling, genetic, cellular and extracellular cues required to instruct trabeculae to form in the heart. Findings from this research will revise our understanding of when and how trabeculae form and provide key information about how to grow and repair this important tissue.Read moreRead less
