Summary
Pulmonary hypertension (elevated blood pressure in the lungs) is a life-threatening condition with few treatment options. We have recently identified a new class of drug that may improve blood vessel function in the lungs and thereby provide a new drug for the management of this group of patients.
An Investigation Of The Involvement Of Clotting Factors In Abdominal Aortic Aneurysm (AAA) Progression Within A Mouse Model

Funding Amount
$189,401.00
Summary
Early stage weakening of the main abdominal artery is present in ~100,000 Australians and currently has no accepted therapy. Development of drug therapies which limit progression of the weakening process is urgently needed. In this study involvement of the clotting cascade in artery weakening will be investigated. The study have been planned in order to identify new strategies which can be developed as treatments for artery weakening in patients.
Development Of An Extended Release Oral Formulation Of Milrinone For Patients With Advanced Heart Failure

Summary
Heart failure is a debilitating condition associated with frequent hospitalization. Milrinone is an effective intravenous drug used to treat acute deteriorations. Previously, oral milrinone failed because of the lack of availability of appropriate formulations. We have developed an oral formulation which provides stable release of the medication. This application will evaluate the effectiveness of the drug in man and provide the documentation to take the project forward for partnership with indu ....Heart failure is a debilitating condition associated with frequent hospitalization. Milrinone is an effective intravenous drug used to treat acute deteriorations. Previously, oral milrinone failed because of the lack of availability of appropriate formulations. We have developed an oral formulation which provides stable release of the medication. This application will evaluate the effectiveness of the drug in man and provide the documentation to take the project forward for partnership with industry as a means to clinical translation.Read moreRead less
Actions Of The Polyphenol Epigallocatechin 3-gallate On Insulin Sensitivity

Summary
This project will determine whether the bioactive compound in green tea (called EGCG) can reduce insulin resistance by enhancing the ability of insulin to open very small blood vessels (called capillaries) in muscle. Opening more capillaries will help glucose to be stored in muscle, thus alleviating insulin resistance. Findings from these studies may have important impact on the management of insulin resistance and type 2 diabetes.
Ion channels are molecular pores of excitable membranes facilitating passage of ions and organic solutes across cellular membranes. An ever-increasing number of human and animal diseases result from malfunctioning ion channels making them to important therapeutic targets, which are modulated by a range of currently prescribed drugs. In the recent years the scientific and medical community has become increasingly aware of the role that mechanosensitive ion channels play in pathology of diseases i ....Ion channels are molecular pores of excitable membranes facilitating passage of ions and organic solutes across cellular membranes. An ever-increasing number of human and animal diseases result from malfunctioning ion channels making them to important therapeutic targets, which are modulated by a range of currently prescribed drugs. In the recent years the scientific and medical community has become increasingly aware of the role that mechanosensitive ion channels play in pathology of diseases including cardiac hyperthrophy and arrhythmias.Read moreRead less
Mechanisms Underlying The Contribution Of Uremic Toxins To Cardiorenal Syndrome

Summary
Cardiorenal syndrome (CRS) is an umbrella term that defines disorders of the heart and kidneys whereby “acute or chronic dysfunction in one organ may induce acute or chronic dysfunction of the other”. We have demonstrated a significant association between heart and kidney fibrosis (scarring) and levels of a uremic toxin called indoxyl sulphate (IS), in relevant animal models and that blockade of production of this toxin reduces cardiac fibrosis. This project aims to explore this association.
Novel Therapy For Heart Failure With Preserved Ejection Fraction

Summary
Heart failure is a major cardiovascular problem. Up to half of the patients have a specific problem with heart muscle relaxation. There is no effective therapy for this type of heart failure. We will investigate the effects of new treatment approach using a range of experimental and clinical methods. If successful the treatment could move quickly into clinical practice.
Novel Therapeutic Interventions To Increase Blood Flow To Skeletal Muscle

Summary
Over the past decade it has become clear that the cytokine interleukin (IL)-6 is produced in and released from tissues such as fat and muscle to mediate metabolic processes. In this respect, it acts in a hormone like manner. During this period it has also become apparent that the hormone insulin increases blood flow to skeletal muscle. There is emerging evidence that IL-6 plays a role, not only in metabolic and signalling processes within skeletal muscle, but also in blood flow. This project wil ....Over the past decade it has become clear that the cytokine interleukin (IL)-6 is produced in and released from tissues such as fat and muscle to mediate metabolic processes. In this respect, it acts in a hormone like manner. During this period it has also become apparent that the hormone insulin increases blood flow to skeletal muscle. There is emerging evidence that IL-6 plays a role, not only in metabolic and signalling processes within skeletal muscle, but also in blood flow. This project will determine whether the cytokine IL-6 is a viable therapeutic target in the treatment of blood flow disorders in patients with type 2 diabetes. This has major ramifications since type 2 diabetes has reached pandemic levels in Australia and is estimated to cost the community approximately 800 million dollars per year.Read moreRead less
Heart failure (HF) describes where the heart cannot pump adequately to meet the bodyÍs needs. Mortality remains high; therefore, there is an urgent need for new treatment approaches. The present grant aims to: (1) evaluate treatments for patients at high-risk for future development of HF (2) examine the ability to safely withdraw unnecessary HF drugs (3) focus on the effect of HF on the kidney via novel treatment strategies (4) examine the emerging role of cancer drugs in development of HF.
DEFINING NONCLASSICAL ANGIOTENSIN SIGNALLING AND CARDIOVASCULAR FUNCTION

Summary
Angiotensin II is a hormone which is well known to contribute to high blood pressure and cardiovascular disease. This proposal will use highly novel compounds that we have synthesised that, for the first time, selectively target nonclassical angiotensin-related binding sites, so called NON-AT1 receptors, which are thought to counteract the deleterious effects of angiotensin II that normally causes fibrosis or scarring of the heart which damages healthy muscle.
