Summary
Mitochondria are the powerhouses in our cells. They burn the carbon fuels we eat and store the energy by making ATP that is used for functions such as muscle contraction and triggering of nerves. Mitochondrial Complex I is a molecular motor that helps to make ATP. “Mitochondrial disease” is often seen when Complex I is not built properly and this results in early childhood death. In this project we will study how Complex I is built and how the mitochondria responds to assembly problems.

Summary
The mitochondrial respiratory chain produces most of the energy required for our cells to grow and function. Complex I is the first enzyme of this chain and its defects are the most prevalent cause of mitochondrial disease, which often results in infant fatality. Defects in complex I have also been associated with Parkinson's disease and oxidative stress. This study will provide important new information into how complex I is built and what goes wrong to cause disease.
Characterising Complex I Function And Dysfunction In Mitochondrial Disease

Summary
The cells in our body produce energy in power plants called “mitochondria”. Mitochondrial disease affects 1 in 5000 live births. Currently there is no cure, but understanding how the genes mutated in mitochondrial disease work is an important step to finding one. Previous research relied on patient samples; however we will employ new technologies allowing us to rapidly model mitochondrial disease in a laboratory setting.
Elucidating The Molecular Regulation Of Gp130 Complex Signalling In Lipid And Glucose Metabolism.

Summary
Overnutrition promotes obesity, which greatly increases the risk of type 2 diabetes and cardiovascular disease. We have provided evidence that activation of gp130 signalling may enhance insulin action and fatty acid oxidation in metabolically active tissues. My research proposal aims to elucidate the molecular regulation of gp130 complex signalling in lipid and glucose metabolism in important metabolic tissues.
