Factors controlling lipid accumulation in non-adipose tissues

Funded Activity Summary

The fat cells of the body are designed to store excess fuel for use when supply from the diet is low, or in situations like exercise, demand is high. Fat also accumulates to some extent in the cells of other tissues types, but in some people the accumulation is excessive. This can have a number of serious effects. In the liver and muscle it can interfere with the ability of insulin to properly regulate the amount of glucose present in the blood, contributing to the development of diabetes. In the liver, fat accumulation can also lead to cirrhosis and liver failure. Cardiovascular complications, resulting in premature death, are also likely. However despite these devastating consequences it is not clear what the underlying cause of the over-accumulation of fat is not known. In this project we will investigate in detail several aspects of fat metabolism that we think are important in controlling how tissues take up fat from the circulation and whether it is subsequently stored or burnt for energy. We will study the amount of fat that is taken up by different tissues of the body under a range of conditions including fed, and short- and long-term fasting. We will also use drugs to inhibit or promote the amount of fat that is burnt, to see if this changes the rate at which fat is taken up by different tissues. In addition we will accelerate, by genetic manipulation, the rate at which some key enzymes of fat metabolism are produced, to determine their effect on the amount of fat that is stored by different tissue types. Our aim is to determine the metabolic processes that influence fat accumulation in those adversely affected tissues such as liver, heart and skeletal muscle. The identification of the most important processes will contribute significantly to the targeting of therapies aimed at preventing excess fat accumulation and its associated diseases.
