Transporting proteins to and within mitochondria. Mitochondria are found in all of our cells and are essential for life. They act like a nuclear power plant, providing the bulk of energy - but they can also kill the cell if the mitochondrial wall (membrane) is opened. Mitochondria contain about 1000 different proteins to function properly but almost all of them are made outside the compartment and must squeeze in through narrow membrane channels. This project will provide new insights into how p ....Transporting proteins to and within mitochondria. Mitochondria are found in all of our cells and are essential for life. They act like a nuclear power plant, providing the bulk of energy - but they can also kill the cell if the mitochondrial wall (membrane) is opened. Mitochondria contain about 1000 different proteins to function properly but almost all of them are made outside the compartment and must squeeze in through narrow membrane channels. This project will provide new insights into how proteins get into mitochondria and what factors help in this process. Besides providing new information about a process that is essential for life, the project will train students in molecular cellular biology techniques and will help foster strong international collaborations.Read moreRead less
Development of novel therapies for the treatment of cancer. Both aging and obesity are significant risk factors for cancer and are becoming a burden on the health care budget. The proposed novel cancer therapy will improve current cancer treatments by enhancing their efficacy, thereby reducing the required dose and minimizing side effects. Such an outcome would not only benefit the well being of the individual but would achieve significant health care cost savings.
Metalloproteomics: A new piece of the systems biology puzzle. Systems biology uses advanced analytical technology to study the complex chemistry of the living cell. Many cellular functions are the result of chemical reactions involving metalloproteins, which are notoriously difficult to study due to the weak bonds between metal and protein that is not normally amenable to traditional proteomic approaches. In partnership with the leading analytical manufacturer Agilent Technologies, this project ....Metalloproteomics: A new piece of the systems biology puzzle. Systems biology uses advanced analytical technology to study the complex chemistry of the living cell. Many cellular functions are the result of chemical reactions involving metalloproteins, which are notoriously difficult to study due to the weak bonds between metal and protein that is not normally amenable to traditional proteomic approaches. In partnership with the leading analytical manufacturer Agilent Technologies, this project aims to adapt and apply advanced mass spectrometry to the study of metalloproteins, developing new methods for studying hundreds of molecules in single experiments. Using the C. elegans model organism the project aims to showcase the importance of metals in biology and develop new solutions for the $2.9 billion proteomics industry.Read moreRead less
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.

Protein structure controls light harvesting in photosynthetic light algae. The strange phenomena of quantum mechanics were not expected to play a direct role in life, however, it appears that quantum effects may be important in the efficient capture of sunlight for photosynthesis. The conditions for the emergence of quantum phenomena appear to be set by the structures of proteins. The aim of this project is to relate protein structure to the emergence of quantum effects in the light harvesting p ....Protein structure controls light harvesting in photosynthetic light algae. The strange phenomena of quantum mechanics were not expected to play a direct role in life, however, it appears that quantum effects may be important in the efficient capture of sunlight for photosynthesis. The conditions for the emergence of quantum phenomena appear to be set by the structures of proteins. The aim of this project is to relate protein structure to the emergence of quantum effects in the light harvesting proteins of marine algae. Understanding the link between structure and quantum effects could improve our knowledge of how nature achieves its remarkable efficiency in utilising the energy from the sun. This is likely to foster new technologies that improve the efficiency of solar energy systems.Read moreRead less

This project aims to use a novel proteomic approach to examine mechanisms of apoptosis at the level of the plasma membrane, mitochondrion, nucleus and cytosol, screening protein extracts of cell organelles by the new technique of SELDI-TOF mass spectrometry in which proteins are adsorbed onto activated chips. This will provide protein mass profiles characteristic of various stages of apoptosis, and will allow identification of proteins of interest by conventional proteomic methods. The establishment of SELDI-MS as a viable tool for cell proteomics would open new opportunities to understand a broad range of cellular functions at the level of protein expression.Read moreRead less

This project aims to develop new knowledge to support the development of strategies to protect wheat from necrotrophic fungi. Crop losses caused by plant diseases are a significant economic, environmental and social challenge in a world facing increased demands on food, fibre and biofuels. Parastagonospora nodorum is an economically important necrotrophic fungal pathogen of wheat. During infection, P. nodorum uses effector proteins to target sensitivity gene products in wheat. This process, known as necrotrophic effector-triggered susceptibility, results in plant cell death and disease. This project aims to investigate the structural basis of necrotrophic effector-triggered susceptibility in the P. nodorum – wheat pathosystem.Read moreRead less
