Development of mathematical and statistical methods and tools in bioinformation science will ensure that Australia is at the cutting-edge of modern biology. This will enhance Australia's reputation for dealing with the exponentially growing body of genomic data emerging from life sciences laboratories throughout the world. The proposed project has a broad range of potential applications in biotechnology, particularly in the medical and agricultural industries. Examples include improvements to livestock, in plant breeding such as drought resistance, and better genetic disease diagnosis, including earlier cancer diagnosis, and personalised treatment.Read moreRead less
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
Mechanism of higher-order chromatin formation and its role in controlling gene expression. The organization of genomic DNA into chromatin has solved one of the most difficult engineering problems required for the development of a multicellular organism; the compaction of over two meters DNA into a cell almost one millionth this size. Importantly, this compaction of the genome into chromatin has also been exploited by the cell to regulate the expression of genes. The aim of this investigation is ....Mechanism of higher-order chromatin formation and its role in controlling gene expression. The organization of genomic DNA into chromatin has solved one of the most difficult engineering problems required for the development of a multicellular organism; the compaction of over two meters DNA into a cell almost one millionth this size. Importantly, this compaction of the genome into chromatin has also been exploited by the cell to regulate the expression of genes. The aim of this investigation is to elucidate how genes are assembled into complex active or inactive chromatin structures by employing a novel in vitro system. This information will have important implications for gene therapy strategies.

The Dynamic Control of Chromatin Structure. A human chromosome is a highly heterogeneous global structure because along its axis, it folds to different extents to form either highly compacted domains that repress the expression of genes or less condensed regions that enable genes to be turned on. Changes to the structure or stability of chromosomes, and the corresponding alterations to gene expression, have been linked to many diseases states like defects in human development and cancer. This s ....The Dynamic Control of Chromatin Structure. A human chromosome is a highly heterogeneous global structure because along its axis, it folds to different extents to form either highly compacted domains that repress the expression of genes or less condensed regions that enable genes to be turned on. Changes to the structure or stability of chromosomes, and the corresponding alterations to gene expression, have been linked to many diseases states like defects in human development and cancer. This study will uncover the underpinning mechanism of how our chromosomes are organised into distinct functional domains, which may offer the potential to develop new strategies to correct chromosomal abnormalities.
