Summary
Receptors on the cell surface allow cells to respond to their environment. We have recently discovered a new pathway for controlling the amount of receptors displayed on the cell surface, errors within which will lead to defects in development and diseases like cancer. We are studying how this new pathway controls the balance between how much receptors are destroyed after being activated and how much are recycled back for re-use.

Summary
The AMP-activated protein kinase is a metabolic stress sensing protein kinase responsible for matching the supply of energy to the body's functions. During vigorous exercise it senses metabolic stress (reduction in energy) caused by muscle contraction and stimulates glucose uptake and burning of fat to provide energy. The AMP-activated protein kinase also regulates the production of nitric oxide that is important in controlling blood pressure and blood clotting. Reduced caloric intake activates ....The AMP-activated protein kinase is a metabolic stress sensing protein kinase responsible for matching the supply of energy to the body's functions. During vigorous exercise it senses metabolic stress (reduction in energy) caused by muscle contraction and stimulates glucose uptake and burning of fat to provide energy. The AMP-activated protein kinase also regulates the production of nitric oxide that is important in controlling blood pressure and blood clotting. Reduced caloric intake activates the AMP-activated protein kinase to suppress energy consuming activities and modify the expression of genes. Many of the conditions that activate the AMP-activated protein kinase (exercise, reduced caloric intake) are associated with a healthy life style, increased longevity and resistance to age onset diseases including cardiovascular disease (atherosclerosis, hypertension), obesity, neurodegeneration and diabetes. By manipulating the gene for the AMP-activated protein kinase in mice we expect to learn more about its key physiological roles and give new insight into the control of age onset diseases.Read moreRead less

Summary
Sphingosine kinase is a protein involved in the development and progression of numerous types of solid tumors and leukaemias. We have recently made a major break-through by identifing how the cancer-inducing activity of sphingosine kinase is controlled. In this study we will target these control mechanisms to develop potential new anti-cancer therapies.
AMP-activated Protein Kinase (AMPK) In Acute Renal Failure

Summary
Acute renal failure is a common complication of any severe illness. Generally, it is the lack of blood flow, or food that leads to this problem. People who are ill are unable to provide adequate blood flow to their kidneys, so the kidneys become diseased and fail to function. This can be fatal. There are, however, mechanisms in the kidney that are designed to avoid this shortage of energy. The aim of these studies is to find out what these protective mechanisms usually do in the kidney, and unde ....Acute renal failure is a common complication of any severe illness. Generally, it is the lack of blood flow, or food that leads to this problem. People who are ill are unable to provide adequate blood flow to their kidneys, so the kidneys become diseased and fail to function. This can be fatal. There are, however, mechanisms in the kidney that are designed to avoid this shortage of energy. The aim of these studies is to find out what these protective mechanisms usually do in the kidney, and understand why they are not more active. We hope to find ways to switch them on earleir, using drugs, so as to protect the kidneys from injury.Read moreRead less
Neuroprotective Functions Of Autophagy Regulators In Alzheimer's Disease

Summary
The accumulation of the beta amyloid protein has a central role in AD and enhancing its removal improves memory loss in animal AD models. This project builds on my recent finding of regulators of a cell housekeeping system, “autophagy” which accelerate removal of beta amyloid in cells. This study will advance knowledge into the protective functions of the autophagy regulators in reducing AD symptoms. Findings from this work might provide the basis for developing effective anti-AD therapeutics.
Structural Investigation Into The Regulation Of The Colony Stimulating Factor Receptor, C-FMS.

Summary
The colony stimulating factor receptor, c-FMS is a member of a family of protein signalling molecules expressed on the cell surface that are implicated in the development of serious diseases in humans, such as inflammatory diseases and cancer. A number of important proteins bind to and regulate c-FMS in different ways. I intend to visualise these interactions to further understand how c-FMS activity is controlled by alternative means.
