Funding Amount
$596,971.00
Summary
Obesity and type 2 diabetes are nationally and globally reaching epidemic rates. This project investigates the regulation of blood flow within muscle and its impact on metabolism. Outcomes from the study may lead to diagnostic tools and treatments for cardiovascular disease associated with obesity, hypertension and type 2 diabetes.
Therapeutic Potential Of Skeletal Muscle Plasticity And Slow Muscle Programming For Muscular Dystrophy

Funding Amount

Summary
There is no cure for DMD, a devastating, life-limiting muscle disease causing progressive muscle wasting in boys and young men. A potential therapy may come from modulating muscle activity patterns to promote a protective slow muscle phenotype through low-frequency stimulation protocols and/or well-described pharmacological ‘exercise mimetics’. This proposal will evaluate their therapeutic merit in mouse models of DMD to answer the key questions to advance this approach to the clinic.
Regulation Of Skeletal Muscle AMP-activated Protein Kinase By Glycogen

Summary
The enzyme AMP protein kinase has three parts (subunits) and is central to controlling the body's metabolism. We have discovered that one subunit is essential for tightly associating the enzyme with muscle glycogen which is a source of high energy and efficient metabolism. We will identify where the enzyme attaches to glycogen, and how diet and exercise alter this association. Understanding this could lead to new approaches for treating Type 2 diabetes where energy metabolism is disrupted.
Nutrient-training Interactions In Human Skeletal Muscle

Funding Amount

Summary
Skeletal muscle accounts for 50% of total body mass with critical roles in body movement and blood glucose regulation. Exercise is a potent stimulus for maintaining/ increasing muscle mass, an effect that is augmented when combined with protein ingestion. The aims of this proposal are to better understand this exercise-nutrient interaction to optimize the prescription of programs and recovery strategies as a countermeasure for muscle degeneration with aging and disease.
The CDP Ethanolamine Pathway: A New Player In Obesity Induced Insulin Resistance

Funding Amount
$652,372.00
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 muscle 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 muscle.
Bioenergetic Deficit In Neurodegeneration: Studies In Motor Neuron Disease (MND)
Funder
National Health and Medical Research Council
Funding Amount
$300,967.00
Summary
Motor neurone disease (MND) is a fatal neurodegenerative disease. There is no known cause and no known cure. We believe that a defect in the way in which the muscle and nerve cells generate energy to sustain survival causes for there to be added metabolic stress on their already high energetic load, ultimately leading to cell death. This project aims to understand the vicious cycle of energy deficiency that leads to the catastrophic events that cause the death of muscle and nerve cells.
