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

Summary
The loss of heart muscle cells during heart attack and heart failure worsens the severity of heart disease. We will study how to protect heart muscle cells by identifying the molecules involved in controlling survival responses. We will use this knowledge to prevent heart muscle cells from dying when exposed to a range of normally harmful conditions. Our study has the potential to prevent heart muscle cell loss, improve heart function and prevent muscle damage in heart disease.

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
