Inhibition Of AMPK Signalling As A Strategy For Decreasing Appetite

Summary
The enzyme AMP-activated protein kinase (AMPK) has previously been implicated in mediating increased food intake in response to fasting and the appetite-inducing hormone ghrelin. In this study we propose to investigate whether inhibition of AMPK has promise as a strategy to reduce hunger in the context of dietary restriction and increases in energy expenditure, such as exercise. We will also test whether a new AMPK inhibitor has the potential to reduce appetite signalling in cells and in mice.
AMPK Control Of Lipid Metabolism: Role In Regulating Energy Balance And Insulin Sensitivity

Summary
The control of appetite and maintenance of a lean body mass along with exercise is important for protecting the body against obesity and increased incidence of Type 2 diabetes and cardiovascular disease. We are investigating how the regulation of lipid metabolism controls appetite and body weight and the extent to which these same controls are important for drugs acting to lower blood lipid levels.
Physiological Function Of Nedd4-2 In Regulating The Epithelial Sodium Channel

Summary
The epithelial sodium channel (ENaC) controls sodium balance, blood volume and blood pressure. Abnormal regulation of ENaC is associated with conditions such as hypertension and pulmonary oedema. Delineating the regulation of ENaC is vital in understanding disease mechanisms and in defining targets for novel therapeutics for the treatment of disorders that arise due to sodium imbalance. This grant will enable us to understand how ENaC is regulated by a novel protein known as Nedd4-2.
