There and back again: understanding the epigenetic remodelling that turns glia into glioma (2020 - 2022)$536,847
Glia are a major cell type within the brain that protect, nourish and insulate neurons. Like neurons, glia are formed via differentiation from neural stem cells. Although differentiation is typically associated with epigenetic locks to prevent a reversal of cell fate, some glia can overcome these inhibitions and differentiate to form glioma tumours capable of rapid proliferation and resistance to treatment.Understanding how glioma cells manage to break out of their chromatin environment jail represents a key means to understanding these tumours and to combating their resistance and lethality. However, the epigenetic changes that occur during glial differentiation and glioma de-differentiation remain a mystery.Here, using the fruit fly as a model organism, together with our new cell-type specific Chromatin TaDa system, we will profile the epigenetic configuration of glial cells within the brain. In order to understand glial differentiation, we will profile the binding of the key cell fate determinant that triggers gliogenesis, Gcm, together with two key epigenetic factors that drive this change, Cbp and the SAGA complex. Finally we will use a well-characterised and relevant fly model of glioma to understand the pathway of differentiation and tumourogenesis. By using of variants of this model to represent different stages of malignancy we will track the epigenetic changes involved in cancer formation. Together with a rapid RNAi screen for chromatin modifying complexes, we will identify the key epigenetic changes to target in interventions. These predictions will be tested on a panel of human glioblastoma cell lines.Our team represents an international collaboration uniquely placed to tackle this problem, consisting of an expert in chromatin states and cell-type specific profiling (CI Marshall), an expert in glia and glial cell fate (CI Giangrande) and experts in glioma and glioma models (AIs Casas Tinto, Quinn and Parsons).

Chromatin State Changes in Intestinal Stem Cell Ageing (2019)$35,000
Adult stem cells must divide to produce new cells to renew and repair tissues. A failure to produce enoughcells could lead to tissue failure while an overproduction of cells can lead to compromised tissue functionand cancer. The incidence of colorectal cancer increases with age, suggesting that in ageing intestinal stemcells this balance may be lost. We use the fruit fly gut as a simple model to study intestinal stem cells. Manyof the signals and genes that regulate human intestinal stem cells are conserved to fruit flies. In youngadult flies the stem cells divide to maintain the gut, but in ageing flies they become mis-regulated andover-proliferate.Changes in cell behaviour such as increased stem cell proliferation usually occur through changes in geneexpression. DNA is packaged into structures called chromatin, some forms of chromatin allow geneexpression, while others are repressive, causing genes to be switched off. This means that chromatin stateplays an important role in stem cell regulation. Individual chromatin components have been shown toregulate stem cells but how chromatin state contributes to stem cell ageing is not known. This project willcharacterize the changes in chromatin states that occur when intestinal stem cells age. This will improveour understanding of how adult stem cells become mis-regulated with age; a critical process for health anddisease. Our work will identify new mechanisms of regulation that could be targeted to improve tissuefunction with age.

Confocal Microscopy (2019)$370,000
Confocal microscope. There is an urgent need for additional confocal microscopes in the Medical Science Precinct research laboratory. By way of example, there is a 2 month waiting list for new users to be trained to use microscopes and a longer waiting period to gain access to image experiments.

Imaging to overcome dementia (2018)$150,000
This grant will enable the purchase of a high-end confocal microscope that will dramatically increase imaging capacity at the Menzies Institute for Medical Research, University of Tasmania. A large number of research groups based at the Menzies are conducting research into the causes of dementia and other neurological diseases, and these will strongly benefit from the acquisition of the new microscope. The microscope will increase both the productivity and impact of the research of these groups, and also enable increased collaborative links between Menzies researchers and national and international partners

A genome-wide analysis of the epigenetic control of learning and memory (2017 - 2019)$547,857
The ability to form and recall memories is a fundamental function of the brain. This ability is affected by neurodegenerative diseases such as Alzheimer's Disease. This project will uncover the regulatory framework that defines the brain cells involved in forming memories, and how these change during Alzheimer's Disease progression.
