Summary
An Australian family with a rare myopathy has led to the discovery of a new gene called PYROXD1; a gene that all cells need to survive. PYROXD1 plays a critical role in protecting cells from oxidative stress. We are using patient samples and mouse models to find out what PYROXD1 does that is vital for cell and animal life. We will test whether redox therapies developed for neurodegenerative disorders might help patients with rare neuromuscular disorders, for whom there are no treatment options.
The Role Of Myo18b In Myopathies And Sarcomere Assembly

Summary
Muscle force is provided by a specific structure within the muscle cell termed the sarcomere. Sarcomeres are the engine-room of muscle cells, that act as complex cellular machines to controls muscle contraction. Many muscle degenerative disorders are caused by defects within the sarcomeres, but how this occurs is not well understood. This grant examines how one such muscle waiting disease, or myopathy, results from mutations in a gene encoding a component of the sarcomere called Myo18b.
Novel Skeletal Muscle Enriched Genes In Muscle Biology And Disease

Summary
Each year hundreds of Australians are born with genetic muscle diseases, however, current methods fail to identify the causative disease gene in ~50% of patients. Here we will use expression patterns in skeletal muscle to prioritize novel candidate disease causing genes. We will functionally test the role of genes expressed in skeletal muscle cells using novel experimental assays. Uniquely, we will for the first time incorporate a novel class of gene (long non-coding RNAs) into our study.
Decrypting The Excitation Contraction Coupling Machinery In Skeletal Muscle

Summary
Skeletal muscle function is dependent upon the fine control of calcium levels. When communication of key proteins in muscle are compromised, calcium levels are uncontrolled leading to severe disabilities. The molecular pathways that control signalling between key muscle proteins is currently unknown and shedding light on this topic will aid in the discovery of therapies for muscle-associated disabilities in disease and with aging.
DHPR ? Subunit Binding To A Variably Spliced Region Of RyR1: A Role In EC Coupling And Myotonic Dystrophy

Summary
We have uncovered a communication pathway between two ion channel molecules in muscle cells that underlies human movement. The pathway is critical in normal mobility and is disrupted in myotonic dystrophy. We will study the molecular components of this pathway to understand normal body function and abnormal function in mytotonic dystrophy. The work will facilitate the design of drugs to relieve the mytotonic dystrophy myopathy and form new and much needed class of specific muscle relaxants.
