Role of suppressor of cytokine signalling proteins (SOCS3) in defective muscle repair and ageing. Old muscles are slower and weaker than young muscles, they are injured more easily and they repair less successfully. This proposal investigates the role of SOCS3-signalling in muscle repair, ultimately to improve healing and to promote healthy ageing that will enable older Australians to enjoy a better quality of life.
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.

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

Summary
This application will define the role of a large cell adhesion molecule, FAT4, in lymphatic vascular development. By understanding how FAT4 functions in lymphatic vessels, we will gain insight to the mechanisms by which mutations in the gene that encodes this protein cause a human lymphoedema syndrome.
T cells play a central role in the immune response. The primary event in T cell activation is the triggering of a specific T cell receptor (TCR). Our studies will define new mechanisms for the regulation of TCR-mediated T cell responses. Our studies may yield novel insight into processes that contribute to the development of type 1 diabetes & inflammatory bowel disease.
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.

Summary
Interrogating the adaptive potential of skeletal muscle. Disruptions to muscle oxidative capacity and growth signalling underpin atrophy and dysfunction with ageing, which impacts on an individual’s quality of life. These biological processes are thought to be mutually exclusive and compete during muscle adaptation. This project aims to define how these processes regulate the extent of muscle adaptation, and how modifying these attributes influence functional capacity in the context of ageing.

Disruptions to muscle oxidative capacity and growth signalling underpin atrophy and dysfunction with ageing, which impacts on an individual’s quality of life. These biological processes are thought to be mutually exclusive and compete during muscle adaptation. This project aims to define how these processes regulate the extent of muscle adaptation, and how modifying these attributes influence functional capacity in the context of ageing. This project will provide fundamental new knowledge in understanding how modifying muscle attributes influence successful ageing. This knowledge will improve resilience, productivity, and wellbeing of all Australians, with implications for reducing societal and economic burden.Read moreRead less

Mechanisms Of Regulation Of Ribosome Biogenesis And Function In Health And Disease

Summary
The PI3K/AKT signalling pathway drives many cancers and until recently was thought to do so by preventing cancer cell death. We have shown this pathway also regulates the synthesis of ribosomes, the cellular “factories” that make protein and by interfering with PI3K/AKT regulated ribosome synthesis, can kill cancer cells. We aim to establish the mechanisms underlying this regulation of ribosome synthesis and to test the hypothesis that ribosome biogenesis is a novel target for cancer treatment.
