Multi-functional probes for global analysis of proteome stress in cells. This project aims to create a suite of multi-functional chemical probes to identify damaged proteins that undergo unfolding or specific modifications in cells under stress. These probes will not only generate fluorescence responses to reflect on protein quality control capacity but allow associated proteins and their networks to be identified in complex cellular environments, which is difficult to achieve by current methods ....Multi-functional probes for global analysis of proteome stress in cells. This project aims to create a suite of multi-functional chemical probes to identify damaged proteins that undergo unfolding or specific modifications in cells under stress. These probes will not only generate fluorescence responses to reflect on protein quality control capacity but allow associated proteins and their networks to be identified in complex cellular environments, which is difficult to achieve by current methods. The expected outcome is to deliver new methodology for a comprehensive understanding of the correlation between quality control machinery, stress responses and cell functions. This should provide significant benefits, including contributing to fundamental knowledge on the molecular causes of neurodegenerative diseases.Read moreRead less

Examining lipid transport by direct visualisation and quantification. This project aims to investigate the least understood aspect of plasma triglyceride metabolism; mechanisms of transport across capillary endothelial cells. This transport regulates plasma triglyceride levels, which are an important factor in determining risk for coronary diseases. An improved understanding of these mechanisms will lead in the long term to better understandings of both heart failure and atherosclerotic heart di ....Examining lipid transport by direct visualisation and quantification.

Summary
Molecular reporters for measuring proteostasis capacity in cells. This project aims to develop fluorescent dyes to report on the change in unfolded protein load, which reflects the proteostasis status in real time in cells under stress conditions. Proteostasis is a housekeeping process cells undertake to maintain the proper folding and functions of proteins. Perturbation of proteostasis has been linked to neurodegenerative diseases, but chemical probes cannot measure the proteostasis capacity in ....Molecular reporters for measuring proteostasis capacity in cells. This project aims to develop fluorescent dyes to report on the change in unfolded protein load, which reflects the proteostasis status in real time in cells under stress conditions. Proteostasis is a housekeeping process cells undertake to maintain the proper folding and functions of proteins. Perturbation of proteostasis has been linked to neurodegenerative diseases, but chemical probes cannot measure the proteostasis capacity in cells. Intended outcomes include a mechanistic understanding of the relationship between protein misfolding, aggregation and proteostasis. This is expected to ultimately benefit the diagnosis of protein folding diseases, including dementia, and improve the quality of life.Read moreRead less
Dissecting a major sulfur cycling pathway: sulfoglycolysis. This project will elucidate the molecular details of sulfoglycolysis, a group of metabolic pathways through which the sulfur-containing sugar sulfoquinovose is catabolized. The project will employ an integrated metabolomic, chemical, biochemical and structural approach to dissect how various sulfoglycolytic organisms degrade sulfoquinovose. This project will deliver a deeper understanding of this major biochemical pathway and develop ne ....Dissecting a major sulfur cycling pathway: sulfoglycolysis.

The project will employ an integrated metabolomic, chemical, biochemical and structural approach to dissect how various sulfoglycolytic organisms degrade sulfoquinovose. This project will deliver a deeper understanding of this major biochemical pathway and develop new chemical and metabolic approaches to manipulate sulfur cycling in the environment. Benefits will include biotechnology applications of newly discovered proteins, and sustainable approaches to reduce our dependence on agricultural fertilisers.Read moreRead less

Summary
Development of sensors for biological redox state. The plethora of antioxidant supplements on the market to prevent aging and disease highlights the great importance of oxidation state in the body. This project involves the development of chemical compounds that can be used to measure oxidation state in living tissue by Magnetic Resonance Imaging (MRI) or microscopy and help us understand various diseases.
Iron, ferroptosis and the biology of ageing. This project aims to determine how and when regulation of iron is lost. Failing iron metabolism during life may dictate the rate of ageing by driving a newly discovered cell death program. Combining biology, chemistry and physics, this collaborative project aims to transform the understanding of the fundamental mechanisms of biological ageing. Anticipated outcomes include new assays for measuring iron in biology and identification of potential pathway ....Iron, ferroptosis and the biology of ageing.
