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.
SENSORIMOTOR AND AUTONOMIC DYSREGULATION IN HEREDITARY SENSORY AND AUTONOMIC NEUROPATHIES

Summary
Specific genetic mutations can lead to widespread changes in the body. Here we are looking at the congenital Hereditary and Sensory Autonomic Neuropathies, the most common of which primarily affects Eastern European Jews. Affected individuals have difficulty walking and controlling their blood pressure, and also have an indifference to pain. This series of experiments aims to increase our understanding of the underlying neurophysiological disturbances.
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.
Migratory Behaviour And Cell Cycle Length Of Enteric Neuron Precursors

Summary
The activity of nerves in the intestine is essential for gastrointestinal function. Correct development of intestinal neurons requires migration of precursors to the correct location and control of proliferation to achieve correct neuron number. In this project we will identify the mechanisms regulating migration and proliferation of intestinal neuron precursors during normal development, and in mice with defects in intestinal neurons that are models of human motility disorders.
