Transfer of expertise and application of the knowledge generated by our research to such fields stands to improve diagnosis of disease predisposition and to improve quality of animal and plant products. These outcomes will benefit all Australians. This knowledge will also improve the education of Australian University students as it contributes to the development of advanced curricula and access to more powerful research methods. In addition, the project will foster important collaborations between Australian researchers and those overseas.Read moreRead less
Single Minded 2: Cross coupling or specificity within the bHLH/PAS transcription factor family? Understanding the mechanisms of action of SIM2 may lead to novel ideas towards drug development for diseases such as Down syndrome and cancer. The SIM2 protein can interfere with activity of the related Hypoxia Inducible Factor (HIF), a protein important in stress response and recovery from stroke. Understanding the molecular basis of this interference could aid current strategies being used to manipu ....Single Minded 2: Cross coupling or specificity within the bHLH/PAS transcription factor family?

Structure and function of a new class of multi-zinc finger (MZF) transcriptional regulators. An understanding of how genes are switched on and off during the development and lifetime of an organism is central to developing the ability to fight many diseases in a rational way. This project will advance our knowledge in this area at a fundamental molecular level by examining the mechanisms through which a specific set of proteins controls gene expression.
Marsupial germ cells and genes. Germ cells are the most fascinating cells in the body, since theirs is the unique responsibility for transmitting life from generation to generation. Studies in mice have suggested that position in the embryo determines their origin, but the early embryology of the mouse is so different from that of other mammals that the events need confirming and extending in another species. The simplified embryology of the tammar wallaby makes it ideal for studying one of the ....Marsupial germ cells and genes.

Studies in mice have suggested that position in the embryo determines their origin, but the early embryology of the mouse is so different from that of other mammals that the events need confirming and extending in another species. The simplified embryology of the tammar wallaby makes it ideal for studying one of the most fundamental questions in the whole of biology: what is the basis for the primal distinction between sex and soma?Read moreRead less
How does the unilaminar blastocyst form an embryo? Marsupials are synonymous with Australia and they are scientifically amazing. An understanding how the single-layered marsupial blastocyst cells are directed to form the complex organisation of an embryo would help us understand the biology underlying the developmental potential of all cells. Understanding these processes is not only of great fundamental interest to developmental biology but also for the development of embryonic stem cell lines. ....How does the unilaminar blastocyst form an embryo?

Understanding these processes is not only of great fundamental interest to developmental biology but also for the development of embryonic stem cell lines. This research will continue Australia's high profile in reproductive biology using one of our iconic native mammals. A greater understanding of marsupial reproduction will also contribute to management of our threatened marsupial populations.Read moreRead less
Identification of nuclear reprogramming factors in oocyte cytoplasm. The mature oocyte contains dominant factors that are capable of erasing tissue specific gene expression profiles of somatic cells. These reprogramming factors would be valuable for dedifferentiation of cells and for nuclear transfer in animal cloning. The research involves determination of reprogramming factors present in active cytoplasm following enucleation of the germinal vesicle, blockage of transcription and translation, ....Identification of nuclear reprogramming factors in oocyte cytoplasm. The mature oocyte contains dominant factors that are capable of erasing tissue specific gene expression profiles of somatic cells. These reprogramming factors would be valuable for dedifferentiation of cells and for nuclear transfer in animal cloning. The research involves determination of reprogramming factors present in active cytoplasm following enucleation of the germinal vesicle, blockage of transcription and translation, and timed cultures. The assays will involve maintenance of reprogramming ability and erasure of somatic gene transcription. By subtractive elimination the function of isolated proteins which are involved in reprogramming will be identified for potential recombinant production.Read moreRead less
Integration of Cellular Gene Regulation Processes. This research program aims to identify specific transcriptional regulatory networks in yeast, to determine how some of these networks interact with each other and within these networks to identify the roles of genes whose functions are currently unknown. It will identify systems regulating genes concerned with one-carbon metabolism, cellular responses to oxidative stress and developmental changes associated with meiosis. It will provide a fra ....Integration of Cellular Gene Regulation Processes. This research program aims to identify specific transcriptional regulatory networks in yeast, to determine how some of these networks interact with each other and within these networks to identify the roles of genes whose functions are currently unknown. It will identify systems regulating genes concerned with one-carbon metabolism, cellular responses to oxidative stress and developmental changes associated with meiosis. It will provide a framework to test regulatory network models and to analyse the molecular basis of interactions between control systems. This research will eventually provide the ability to predict how cells respond to drugs and other environmental stimuli.Read moreRead less
Adaptive Evolution of BRCA1 in Ancestral Mammals. This project investigates adaptive evolution of BRCA1 in the early radiation of mammals. We will test the hypothesis that the evolution of mammary glands and X chromosome inactivation has resulted in modification of the BRCA1 protein sequence as it aquired new roles in these processes. We will also investigate the importance of these changes inducing compensatory changes in other parts of the protein.
Regulation of the EphA3 receptor tyrosine kinase in vertebrate development. The Eph/ephrin system has a critical role in normal embryonic development. Amongst vertebrates, the EphA3 gene is one of the most highly conserved genes in this system with critical roles in development of the visual system and in other developmental processes. Understanding how this gene is regulated will help us to understand the critical role of EphA3 in the basic biology of humans and other animals.

Understanding how this gene is regulated will help us to understand the critical role of EphA3 in the basic biology of humans and other animals. This knowledge may also shed light on the basis of congenital abnormalities and other pathological processes and possibly help us to understand how to prevent or treat these conditions.Read moreRead less
