Summary
This study investigates a new therapeutic action recently discovered for flecainide, an antiarrhythmic agent that we find to completely prevent and inherited form of stress-induced arrhythmias called CPVT. The findings will provide the first detailed mechanistic understanding of an antiarrhythmic drug, findings that will also give a new direction for drug design to control common arrhythmias such as occur in diseases such as coronary artery disease.

Summary
Calcium signaling is disrupted in muscle diseases, including muscle weakness in the elderly. This is a significant problem as all mobility depends on calcium signaling and its disruption can cause serious disability and death. To alleviate defective calcium signaling, the underlying molecular machinery must be fully understood, yet we have only a broad outline of the processes. We will address this problem to provide a platform for alleviating age-related muscle weakness.
