Summary
This research will use a combination of genomic, biochemical and functional genomics approaches to investigate the role of the atypical mCH form of DNA methylation in neuronal genome regulation and function, and provide new insights into the role of the epigenome in healthy brain function and neural pathologies.
Epigenetic Changes In The Prostate Cancer Microenvironment

Summary
Many men with prostate cancer have slow-growing tumours that are unlikely to spread outside the prostate. These men with low-risk cancer are often monitored to prevent unnecessary aggressive treatments. However, the current methods used to distinguish between slow-growing and aggressive tumours are imprecise and there is a risk of missing aggressive tumours. We aim to identify new biomarkers of prostate cancer by measuring modifications to the DNA in the tumour and surrounding cells
CTCF is a unique architectural protein that regulates the three-dimensional (3D) folding of the genome to switch our genes on, or off. This is important, as it affects how DNA is arranged inside the cells, which is turn assures correct gene expression patterns. Here, we will define the role of CTCF in organizing the 3D genome architecture and identify genetic and epigenetic states that control its function.
Four Dimensional Epigenome Remodelling: Implications For Endocrine Resistance In Breast Cancer

Summary
Patients with estrogen receptor positive breast cancer receive endocrine therapy, however half fail to respond and relapse. Endocrine resistant breast cancer currently represents the most significant challenge to breast cancer treatment. We suggest that three-dimensional epigenetic remodelling is an underlying mechanism that determines endocrine sensitivity that we will exploit as a novel therapeutic strategy to effectively treat patents with recurrent disease.
Defining Epigenetic Predictors Of Long-term Outcomes Of Preterm Birth

Summary
On average, those born premature do worse health-wise than those born at term. However, some do worse than others. Our aim is to identify these people at birth to better help doctors and parents to closely monitor their health. For this, we will be “reading the diary of pregnancy” in the molecules added to chromosomes in blood during pregnancy in young adults with will characterised states of health. We will analyse DNA from blood that we will extract from stored heel prick spots.
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. This will provide significant benefits, such as a new molecular understanding of heredity that could be key to thriving in a changing environment.Read moreRead less
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
