Epigenetic and neurobehavioural changes in a new mouse model of foetal alcohol spectrum disorders. Foetal alcohol syndrome involves changes in growth, skull structure, central nervous system defects and intellectual disabilities. This project will use a mouse model to study the underlying causes of this disorder, focussing on brain structure and function, and aim to identify markers that can be used for early diagnosis and treatment.
The role of transient DNA methylation on muscular adaptation. Regulation of gene expression is fundamental to all living organisms. This project will utilise the preliminary evidence that DNA methylation, an imprint establishing the phenotype of a specific organ, rapidly drops after an exercise bout, contradicting the dogma that DNA methylation is a locked process.
Extracellular vesicles in the inheritance of acquired traits. This project aims to examine the role of extracellular vesicles (EV) in the transfer of regulatory RNA from somatic cells to germline cells. This project suggests that somatic EVs from the epididymis transfer regulatory RNA to the sperm, and that this RNA exerts its effects in the early embryo of the next generation. This will provide significant benefits, such as a new molecular understanding of heredity that could be key to thriving ....Extracellular vesicles in the inheritance of acquired traits.

This project suggests that somatic EVs from the epididymis transfer regulatory RNA to the sperm, and that this RNA exerts its effects in the early embryo of the next generation.

The nature and extent of mammalian transgenerational epigenetic inheritance. This project aims to understand how biological information can be passed from one generation to the next without being encoded in the genes. The results of this study will inform us how this can happen, and shed light on how often it happens in mammals.
System-level characterisation of the siphonophore, Indo-Pacific man o' war. The Indo-Pacific man o' war (bluebottle), is a cnidarian from the siphonophore order. These animals frequent Australian beaches in swarms and cause thousands of stings every year. The project proposes to profile the genome, transcriptome, epigenome, and proteome of the bluebottle to gain insight into its life cycle, its behaviour, and toxins. Expected outcomes include the generation of novel information related to bluebo ....System-level characterisation of the siphonophore, Indo-Pacific man o' war. The Indo-Pacific man o' war (bluebottle), is a cnidarian from the siphonophore order. These animals frequent Australian beaches in swarms and cause thousands of stings every year. The project proposes to profile the genome, transcriptome, epigenome, and proteome of the bluebottle to gain insight into its life cycle, its behaviour, and toxins. Expected outcomes include the generation of novel information related to bluebottle gene regulation and its toxin repertoire, which will be highly beneficial for the design of future sting treatment strategies. Given that the bluebottle is a colony made of functionally specialised polyps, this study will also provide significant novel insight into the origins and evolution of animal multicellularity.Read moreRead less
How is molecular information passed between generations? This project aims to determine the mechanisms responsible for the inheritance of acquired traits. Sometimes the environment can have effects on the phenotype of not only the exposed individual, but also their children and grandchildren. While it is clear that this can occur, what is not clear is the mechanism by which this happens and the frequency at which it happens. This project will combine use of the model organism Caenorhabditis eleg ....How is molecular information passed between generations?

While it is clear that this can occur, what is not clear is the mechanism by which this happens and the frequency at which it happens. This project will combine use of the model organism Caenorhabditis elegans with biochemistry and structural biology to determine what the molecular mechanism is by which this "transgenerational epigenetic inheritance" occurs.Read moreRead less
Understanding the role of endogenous siRNAs in the maintenance of genomic defenses. The inappropriate expression of retrotransposons can cause increased genomic instability. The underlying molecular pathways that control retrotransposon expression are not known. This project proposes to investigate this question at a molecular level how naturally occurring small endogenous noncoding RNAs (endo-siRNAs) enforce the epigenetic silencing of retrotransposons and examine the likely impact of endo-siRN ....Understanding the role of endogenous siRNAs in the maintenance of genomic defenses. The inappropriate expression of retrotransposons can cause increased genomic instability. The underlying molecular pathways that control retrotransposon expression are not known. This project proposes to investigate this question at a molecular level how naturally occurring small endogenous noncoding RNAs (endo-siRNAs) enforce the epigenetic silencing of retrotransposons and examine the likely impact of endo-siRNAs expression in the packaging and maintenance of retrotransposons. Understanding this fundamental question will advance the scientific knowledge of small RNA functions in our genomic defense systems. Read moreRead less
Radical change in the architecture of a nucleus: loss of typical DNA organisation systems in dinoflagellates. The genetic blueprint of all higher cells is stored in the cell nucleus, and proteins called histones provide the filing system for compactly stacking and organising the cell's DNA. One group of organisms, the dinoflagellate algae, have lost this histone system. This project will provide insight into their alternative DNA management systems.
Decoding Bacterial Epigenetic Regulation. This project aims to characterise bacterial epigenetic regulation by determining the mechanism of action and impact of bacterial DNA methylation.

This project aims to characterise bacterial epigenetic regulation by determining the mechanism of action and impact of bacterial DNA methylation. This project expects to generate new knowledge about fundamental aspects of bacterial gene regulation, using a novel combination of cutting edge DNA and RNA sequencing, proteomic and bioinformatic approaches. The expected outcomes of this project will provide new tools to facilitate the integration of epigenomic analysis into genomic studies, exponentially increasing the volume and value of data gathered. This would provide significant future benefits to all academic, biotechnology, agricultural, veterinary and pharmaceutical applications that involve bacterial genomic analysis.Read moreRead less

Summary
Switching on an immune response involves major changes in the gene expression program of the immune cells. These changes in gene expression take place in the context of DNA packaged into the nucleus in a structure known as chromatin. We will investigate the relationship between chromatin and gene expression changes and how this relationship plays a role in the timing of the immune response. This information will be useful in developing novel means of controlling aberrant immune responses.
