Transcriptional regulation by microRNAs. This project aims to better understand microRNAs, which are of central importance to how genes are regulated. Despite recent data indicating microRNAs may also play more extensive and diverse roles as nuclear regulators of gene transcription, research has been restricted to their well known mechanism of action in the cytoplasm where they post transcriptionally silence genes. This project will investigate the potential for microRNAs to regulate transcripti ....Transcriptional regulation by microRNAs. This project aims to better understand microRNAs, which are of central importance to how genes are regulated. Despite recent data indicating microRNAs may also play more extensive and diverse roles as nuclear regulators of gene transcription, research has been restricted to their well known mechanism of action in the cytoplasm where they post transcriptionally silence genes. This project will investigate the potential for microRNAs to regulate transcription on a genome-wide scale and will thereby reveal the full extent of mechanisms by which these important genetic switches control gene expression networks the characteristics of cells. This is of fundamental significance to our understanding of gene regulation.Read moreRead less
Systems modelling of the cardiac fibroblast. The cardiac fibroblast is a specialised cell in the heart. New evidence shows that this cell type is central to heart function, but relatively little is known about how and why. This project will develop mathematical modelling to characterise how the cardiac fibroblast regulates the functioning of the adult heart.
Systems-level characterization of scaffold protein signalling networks. The PEAK family of cell signalling scaffolds regulate cellular responses critical for normal development and physiology. This project will adopt a ‘holistic’ approach to characterizing their mechanism and function, integrating experimental and mathematical approaches and developing predictive computational models. It aims to generate fundamental new knowledge in cell, computational and synthetic biology with broad relevance ....Systems-level characterization of scaffold protein signalling networks. The PEAK family of cell signalling scaffolds regulate cellular responses critical for normal development and physiology. This project will adopt a ‘holistic’ approach to characterizing their mechanism and function, integrating experimental and mathematical approaches and developing predictive computational models. It aims to generate fundamental new knowledge in cell, computational and synthetic biology with broad relevance that will foster establishment of new international linkages. This research will also identify strategies for engineering novel scaffolds that re-program cellular behaviour towards specific, applied outcomes, with potential benefit for the fields of synthetic biology, bioengineering and biotechnology.Read moreRead less
Defining the molecular switches that govern discrete cellular fates. This project aims to elucidate how mammalian cells exploit the same molecular machinery to perform completely distinct jobs. While the repurposing of proteins by cells seems widespread, the mechanisms by which this occurs remains largely undefined. The project expects to generate new knowledge in the areas of cell signalling and systems biology, with important implications for many multi-functional proteins. It will utilise a h ....Defining the molecular switches that govern discrete cellular fates. This project aims to elucidate how mammalian cells exploit the same molecular machinery to perform completely distinct jobs. While the repurposing of proteins by cells seems widespread, the mechanisms by which this occurs remains largely undefined. The project expects to generate new knowledge in the areas of cell signalling and systems biology, with important implications for many multi-functional proteins. It will utilise a highly innovative and interdisciplinary approach that tightly integrates mathematical modelling and biological experiments. The expected outcomes will aid strategies for reprogramming cells towards a desired phenotype, which will bring significant benefits to the fields of synthetic biology and bioengineering.Read moreRead less
The discovery and characterisation of novel protein regulators of blood cell formation. All of the mature blood cells in the human body are derived from a common ancestor cell type known as a stem cell. Our proposed studies will enhance our knowledge of how functional, mature blood cells are formed from stem cells and how dysregulation of these normally tightly controlled pathways can give rise to severe blood diseases.
