Arrhythmogenesis in catecholaminergic polymorphic ventricular tachycardia: insights from a RyR2 R4496C knock-in mouse model.

abstract：:Recent advances in cardiac physiology identify the integrin-linked kinase (ILK) as an essential molecule regulating cardiac growth, contractility, and repair. A key transducer of biochemical signals initiated at the plasma membrane by cell-matrix interactions, ILK now emerges as a crucial player in mechanotransduction...
