Sphingosine Kinase: A Target For Obesity-induced Insulin Resistance

Funding Amount

Summary
Insulin resistance, a characteristic of type 2 diabetes, is linked to abnormal metabolism of lipid (fat) in tissues such as liver and muscle. This project aims to identify a novel pathway which may promote a build up of lipids in liver and therefore leads to the development of type 2 diabetes. This work may provide a basis for understanding and optimizing treatment of insulin resistance by regulating the control of fat metabolism in liver.
REGULATION OF LIPID METABOLISM IN SKELETAL MUSCLE BY IDOL – A Novel Degrader Of The Very Low Density Lipoprotein Receptor

Summary
More than 1 in 5 Australians are estimated to have increased levels of fats (triglycerides; TGs) in the blood, commonly due to excess dietary intake or genetics. The excess TGs are deposited in skeletal muscle where they can cause insulin resistance, increasing the risk of developing diabetes, the fastest growing chronic condition in Australia. I will examine whether a recently identified protein, IDOL, can reduce accumulation of TGs in skeletal muscle and protect against insulin resistance.

Understanding The Role Of Sugar Metabolism In Liver Tumour Growth

Summary
Primary liver cancer is a deadly disease with limited chemotherapeutic options. The investigators of this proposal have recently determined that sugar intake (but not fat or complex carbohydrate) is a dominant driver of liver tumour growth in mice. The current proposal will investigate the specific contributions of glucose versus fructose in tumour burden, and determine whether blocking the conversion of sugars to fat in the liver represents a therapeutic strategy to block tumour growth in mice.
Does Periodic Fasting Improve Insulin Sensitivity And Metabolic Health In Humans?

Summary
A large body of evidence for the health benefits and life-extending properties of dietary restriction exists. Recent findings suggest that periods of fasting can have beneficial effects, even without an overall reduction in caloric intake. This proposal will compare periodic fasting with and without weight loss, versus daily caloric restriction on metabolic health outcomes in humans and examine mechanisms that may contribute to this effects.
