Summary
Post-translational modification of lysine residues has a major influence on protein function. Many mitochondrial proteins are affected by lysine modifications and recent work has described a role for sirtuin enzymes in regulating these processes. This proposal will investigate whether targeted increases in sirtuin activity can improve mitochondrial function and insulin action in mouse models of obesity and insulin resistance.

Summary
The PREVIEW Study will identify the most efficient lifestyle pattern for the prevention of type-2 diabetes in a population of pre-diabetic overweight or obese individuals. The project comprises two distinct lines of evidence, an intervention study and population studies. The focus will be on diet (specifically protein and glycemic index) and intensity of physical activity, as well as their interaction with the lifestyle factors, habitual stress, sleeping pattern, behavioural, environmental, cult ....The PREVIEW Study will identify the most efficient lifestyle pattern for the prevention of type-2 diabetes in a population of pre-diabetic overweight or obese individuals.

Investigation Of The Mechanism By Which Medium Chain Fatty Acids Prevent The Development Of Obesity And Insulin Resistance - What Role For GPR84?

Funding Amount
$512,541.00
Summary
Medium chain fatty acids do not induce the same degree of obesity and insulin resistance as long chain fatty acids and this is due to changes in metabolism in skeletal muscle and adipose tissue. In this proposal we will investigate whether medium chain fatty acids induce their beneficial effects by interacting with a specific G protein-coupled receptor named GPR84. This receptor may be a new therapeutic target for the treatment of metabolic diseases.
Impact Of Islet Beta Cell Heparan Sulfate In Type 2 Diabetes

Funding Amount
$576,777.00
Summary
Type 2 diabetes (T2D) is a chronic metabolic disease which ultimately leads to the death of insulin-producing islet beta cells, elevated blood sugar levels and daily insulin injections. Since beta cells require the complex sugar heparan sulfate (HS) for survival, we will investigate whether beta cell failure in T2D results from defective HS production. HS replacement will be evaluated as a new therapeutic strategy for preserving beta cell function and preventing the need for insulin injections.
