Novel target of amiloride analogues - picornaviral RNA polymerase. Picornaviruses cause a range of diseases such as poliomyelitis, meningitis, myocarditis, hepatitis A, neonatal sepsis and common cold. No antiviral treatment is available for these infections. Nearly 50% of antiviral drugs used in medicine are viral polymerase inhibitors; however picornaviral RNA polymerase has been largely overlooked as a drug target. We have discovered a group of compounds that inhibit picornaviral RNA polymera ....Novel target of amiloride analogues - picornaviral RNA polymerase.

Nearly 50% of antiviral drugs used in medicine are viral polymerase inhibitors; however picornaviral RNA polymerase has been largely overlooked as a drug target. We have discovered a group of compounds that inhibit picornaviral RNA polymerase. This project aims to define the inhibition mechanism and to evaluate a potential use of these compounds for antiviral drug development.Read moreRead less
Drug targets in the relict plastid of malaria parasites. Malaria is a major world health problem and new drugs are needed urgently. Essential genes are potentially excellent targets for anti-malarial drugs. This project will use a novel strategy to identify genes that the parasite cannot exist without. Function and drug potential of these genes will be explored.
Discovering the role of pH in regulating mitochondrial biogenesis, so as to improve the design of preventative programs aimed at healthy ageing. Mitochondria are essential for life, and maintaining mitochondrial function plays an important role in preventing the progression of many age-related diseases. It has previously been shown that minimising the decrease in muscle pH that occurs during physical activity promotes greater improvements in mitochondrial function. The next step is to discover t ....Discovering the role of pH in regulating mitochondrial biogenesis, so as to improve the design of preventative programs aimed at healthy ageing. Mitochondria are essential for life, and maintaining mitochondrial function plays an important role in preventing the progression of many age-related diseases. It has previously been shown that minimising the decrease in muscle pH that occurs during physical activity promotes greater improvements in mitochondrial function. The next step is to discover the effects of altering pH on acute and chronic activity-induced changes in signalling proteins and genes that are involved in the regulation of skeletal muscle mitochondrial biogenesis. These experiments will significantly advance the knowledge base concerning factors regulating mitochondrial biogenesis, and will contribute to optimising the design of preventative programs aimed at healthy aging.Read moreRead less

Basic biochemistry and the metabolic regulation of proliferation remain as the fundamental building blocks of knowledge in cell biology that have enabled breakthrough advances in biology and medicine. Polyamines are unique and ubiquitous low-Mr amines that play vital roles in many biological processes, including proliferation, DNA/RNA synthesis, etc. This proposal will mechanistically dissect the "new" biochemistry of polyamines, as we have discovered that polyamines are regulated by iron at 2-major levels, involving >10-key polyamine pathway proteins. This proposal represents first-in-field studies specifically designed to dissect mechanisms involved in this relationship. Our Central Hypothesis is that iron regulates polyamine metabolism.Read moreRead less
Reproductive Autonomy in the Genomic Age. This project aims to provide a better way to help people to think and reflect about new genetic tests in pregnancy. These tests are on the rise. Yet they are occurring in a setting that is overly individualistic and underplays problems that can come from increased information and choice.

These tests are on the rise. Yet they are occurring in a setting that is overly individualistic and underplays problems that can come from increased information and choice. This project will involve an interdisciplinary team to generate new theoretical and practical knowledge to re-frame the concept of 'reproductive autonomy'. Expected outcomes include new bioethics knowledge, innovations in research methodologies, new data and recommendations for practice. The project will provide benefits by generating the first analysis of how reproductive autonomy needs to change to ensure new tests in pregnancy are offered and used well.Read moreRead less
The role of immune cells in controlling blood flow. The project aims to increase our understanding of how neurons in the central nervous system alter blood flow to meet their metabolic needs. Tight control of the retinal vasculature is crucial for maintaining normal vision. Unlike most blood vessels in the body, those in the retina and brain receive no direct neural control. Rather, they rely on support cells to communicate the needs of neurons. This project aims to examine whether resident immu ....The role of immune cells in controlling blood flow. The project aims to increase our understanding of how neurons in the central nervous system alter blood flow to meet their metabolic needs. Tight control of the retinal vasculature is crucial for maintaining normal vision. Unlike most blood vessels in the body, those in the retina and brain receive no direct neural control. Rather, they rely on support cells to communicate the needs of neurons. This project aims to examine whether resident immune cells called microglia regulate blood vessels in response to neural activity. This knowledge would improve our understanding of how blood vessels are controlled in the retina and brain. The results may guide the development of novel ways of examining blood vessel function.Read moreRead less
