Many heart diseases are associated with impairment of energetics of the heart. Improving the heart's energetics can lead to improved survival and long-term outcomes. Perhexiline is a heart medication that works by improving the way the heart uses energy. Although effective, it is associated with long-term toxicities. Better understanding of this medication may lead to less adverse effects and also provide a basis for further investigation of drug development in the future.
Oxidative Processes In Vascular Health And Disease

Summary
The process that turns cut fruit brown when it is exposed to air is thought to cause disease of our blood vessels and heart as we age. Despite what we first thought, 'blocking' this oxidation process with antioxidant supplements does not lower heart disease. This is because oxidation not only causes harm but also is useful and essential for normal body function. Our research program aims to show which oxidative processes are needed for blood vessel health or cause vessel disease.
Targeting The Class IIa Histone Deacetylases In Metabolic Disease

Funding Amount
$408,388.00
Summary
Dysfunctional metabolism in skeletal muscle is integral in the development of metabolic diseases, such as obesity and type 2 diabetes. This project will examine proteins that alter the way genes are expressed for their role in dysfunctional metabolism in muscle. This project could uncover new therapies for the treatment of metabolic diseases.

Over the last decade, improvement in cardiovascular health has been primarily the result of a better understanding on how to control 'bad' (or LDL) cholesterol. The significance of the proposed studies is that, on the one hand, they will provide new information on how 'good' lipoproteins protect us from atherosclerosis. This information can then be used to regulate 'good' cholesterol in a meaningful manner. On the other hand, the proposed studies will provide fundamental insights into how a range of lifestyle factors, physiological processes and pathological conditions relate to both the function of blood vessel-lining cells and susceptibility of individuals to atherosclerosis.Read moreRead less

Mitochondrial L-arginine Transport And Its Role In The Pathogenesis Of Heart Failure

Funding Amount
$525,660.00
Summary
Heart failure is a common disorder that is marked by significant symptoms and reduced survival. Reduced cardiac performance is the key responsible mechanism. At the tissue level, altered energy metabolism is a major contributor. Mitochondria are the cellular elements that produce energy and in this project we aim to study how a key process that regulates mitochondrial activity behaves in the setting of heart failure.
Mechanistic Studies Of Medium-chain Fatty Acids In Metabolism And Obesity.

National Health and Medical Research Council
Funding Amount
$316,449.00
Summary
A major factor underpinning metabolic disorders such as obesity and diabetes is unlimited access to high-fat diets. However, not all lipids have detrimental effects on metabolic health. Diets rich in medium-chain fatty acids are associated with reduced adiposity and preserved insulin action. This project will examine the mechanisms that underlie the beneficial effects of MCFA, with focus on a novel MCFA-receptor (GPR84) as a potential therapeutic target in the treatment of metabolic disease.
Mitochondrial Sirtuins, Energy Metabolism And Insulin Action
Funder

Funding Amount
$582,925.00
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.
