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.
Many Ys in monotremes: multiple sex chromosomes and sex determination in platypus and echidna. Platypus and Echidna are Australian icons, even featuring on our coins. Their unusual biology and ancient relationship to humans make them unique for understanding the mammalian genome, as demonstrated by our recent discovery of ten sex chromosomes in platypus that link mammal and bird sex. Still little is known about their genome, embryo development and how sex is determined. We will identify new gene ....Many Ys in monotremes: multiple sex chromosomes and sex determination in platypus and echidna. Platypus and Echidna are Australian icons, even featuring on our coins. Their unusual biology and ancient relationship to humans make them unique for understanding the mammalian genome, as demonstrated by our recent discovery of ten sex chromosomes in platypus that link mammal and bird sex. Still little is known about their genome, embryo development and how sex is determined. We will identify new genes on all ten sex chromosomes and investigate how they determine sex. The set up of an Australian Monotreme Resource Centre will be crucial for this research and attract worldwide high profile collaborations. We will answer important general questions in monotreme biology and contribute to our understanding of sexual abnormalities in humans.Read moreRead less

Single minded 1 in neuron development and satiety signalling. An understanding of how Single minded 1 (SIM1) regulates target genes may allow new pharmaceutical approaches to be designed to combat obesity. As Sim1 belongs to a family of closely related gene regulatory proteins which function in early development and homeostasis, deciphering the molecular control mechanisms of Sim1 may help understand how the related factors function in processes such as angiogenesis, response to low oxygen stres ....Single minded 1 in neuron development and satiety signalling. An understanding of how Single minded 1 (SIM1) regulates target genes may allow new pharmaceutical approaches to be designed to combat obesity. As Sim1 belongs to a family of closely related gene regulatory proteins which function in early development and homeostasis, deciphering the molecular control mechanisms of Sim1 may help understand how the related factors function in processes such as angiogenesis, response to low oxygen stress, invasion of environmental pollutants and autism spectrum diseases. The ability to manipulate these factors would be of great benefit in treating a range of disorders, but a thorough molecular understanding of these factors needs be obtained prior to attempting design of pharmaceuticals.Read moreRead less
Identification of Biological pathways regulated by circular RNAs. Circular RNAs (circRNAs) are a, recently discovered molecule. circRNAs are highly abundant and expressed in a tissue and disease specific manner. Yet, currently the understanding of how circRNAs regulate biological processes is very poor. This project aims to use pooled shRNA libraries to screen a large panel of cell lines and systematically identify cellular activities that are regulated by circRNAs. The expected outcome of this ....Identification of Biological pathways regulated by circular RNAs. Circular RNAs (circRNAs) are a, recently discovered molecule. circRNAs are highly abundant and expressed in a tissue and disease specific manner. Yet, currently the understanding of how circRNAs regulate biological processes is very poor. This project aims to use pooled shRNA libraries to screen a large panel of cell lines and systematically identify cellular activities that are regulated by circRNAs. The expected outcome of this study will be a catalogue of functionally active circRNAs. Over the past decades, the wealth of knowledge on the function of linear mRNAs has had a significant impact on medicine and agriculture. Similarly understanding how circRNAs regulate cellular activities may have an analogous impact on humans.Read moreRead less
The role of the neuronal Hu proteins in the regulation of the BMP signalling pathway. We aim to understand the critical decision of a neural progenitor to commit to becoming a neuron. The BMP signalling pathway is central in this decision. Neural progenitors appear to become insensitive to BMP signals, and this lack of signalling leads to neuronal differentiation. We hypothesise that neuronal identity is regulated by an unusual genetic switch- the translational regulation by the neuronal Hu pr ....The role of the neuronal Hu proteins in the regulation of the BMP signalling pathway. We aim to understand the critical decision of a neural progenitor to commit to becoming a neuron. The BMP signalling pathway is central in this decision. Neural progenitors appear to become insensitive to BMP signals, and this lack of signalling leads to neuronal differentiation. We hypothesise that neuronal identity is regulated by an unusual genetic switch- the translational regulation by the neuronal Hu proteins of two proteins in the BMP pathway. Verification of a post-transcriptional regulatory mechanism for cell fate determination would be a major discovery, and may prompt investigation of how to harness the neuron-inducing function of the Hu proteins to address the therapeutic need for new neurons in neurologic diseases.Read moreRead less

Cancer and dementia are primarily afflictions of the aged and are increasingly important in an aging Australian population. 95% of all Alzheimer's disease is spontaneous (not inherited) but we know little about the molecular mechanisms underlying it. Our discovery that truncated presenilin proteins potently inhibit normal protein function suggests that changes in presenilin function in aged cells might be a common molecular link between spontaneous and inherited Alzheimer's disease and could contribute to frontotemporal dementia and cancer. Our research will show whether this phenomenon might provide a breakthrough in our understanding of these diseases and be a productive area for research into their amelioration and/or prevention.Read moreRead less
The transcriptional control of lymphatic vessel development. Lymphatic vessels are a vital, but often overlooked, component of the cardiovascular system. These specialised vessels return tissue fluid to the bloodstream, absorb dietary lipids and transport cells of the immune system throughout the body. Defects in the growth and development of lymphatic vessels result in disorders including lymphedema, obesity, inflammatory diseases and cancer. This project aims to define how transcription factor ....The transcriptional control of lymphatic vessel development. Lymphatic vessels are a vital, but often overlooked, component of the cardiovascular system. These specialised vessels return tissue fluid to the bloodstream, absorb dietary lipids and transport cells of the immune system throughout the body. Defects in the growth and development of lymphatic vessels result in disorders including lymphedema, obesity, inflammatory diseases and cancer. This project aims to define how transcription factors program lymphatic vessel identity and control the development of lymphatic vessel valves. This knowledge will provide new insight into the fundamental mechanisms by which the lymphatic vasculature is constructed during development.Read moreRead less
