Summary
As a muscle biologist, I study the mechanisms that regulate skeletal muscle size, so that we can develop therapies for muscle wasting. What sets my research apart is my combination of expertise in muscle biology, and the use of recombinant viral vectors for altering the expression of specific genes exclusively in skeletal muscles. Our approaches enable us to study the inner workings of muscles in ways others cannot, and develop promising new therapies for treating muscle diseases.
Control Of TGF-beta Superfamily Signalling In Human Disease

Summary
Members of the transforming growth factor ? (TGF-?) family of proteins play crucial roles in adult tissue homeostasis. In recent years a new paradigm has emerged suggesting that inhibition of TGF-? signalling could be an effective strategy for restoring homeostasis in disease-affected tissues. Dr Harrison’s overall research strategy is based on this concept, and is particularly focussed on developing specific antagonists of individual TGF-? proteins.
Mechanisms Of Abnormal Expression Of The IGF2 Gene In Disorders Affectin Foetal Growth

Summary
The IGF2 gene is crucial for foetal growth. Only the copy inherited from the father is active, a phenomenon named parental imprinting. In some children with foetal overgrowth or growth retardation, the deregulation of imprinting of the IGF2 gene during the first days of foetal development will influence subsequent growth and will also have major implications in post-natal and adult life. We will investigate the mechanisms resulting in abnormal imprinting of IGF2 early in development.
Tolerance Induction By Antigen-presenting Cell-targeted Antigen

Summary
We have found that by ‘targeting’ antigen to the cells that ‘train’ the immune system we have been able to prevent the development of autoimmune disease. In the research proposed here we aim to develop new ways in which antigens can be targeted to these cells so that this approach can be applied clinically. The proposed studies will also determine how antigens targeted in this way restore self-tolerance and prevent autoimmune disease.
Fetal Cardiovascular Development And The Impact Of Chronic Hypoxia And Fetal Growth Restriction

Summary
Low birth weight occurs in 7% of Australian babies and is associated with an increased risk of cardiovascular disease in adult life. Understanding the mechanisms underlying heart and blood vessel development in low birth weight babies will lead to improved identification and intervention in those individuals at risk of cardiovascular disease in adult life, improving heart health for Australians. Reducing cardiovascular disease will improve both quality and quantity of life for Australians.
The adult heart has an extremely limited capacity for regeneration. In contrast, I recently discovered that the newborn heart can completely regenerate following a heart attack. How and why the heart loses this regenerative capacity after birth is not known. This Fellowship aims to unravel the genetic circuits that govern cardiac regenerative capacity. The proposed research program will develop novel therapies for heart regeneration through molecular targeting of regulatory RNA molecules.
Targeting The Class IIa Histone Deacetylases In Metabolic Disease

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.
