Why the study?
Understanding chamber-specific ion channel expression profiles is essential for comprehending cardiac electrophysiology, arrhythmia mechanisms, and developing chamber-selective therapeutic strategies.
Provides a comprehensive overview of chamber-specific ion channel expression profiles in the human heart, which is foundational for understanding arrhythmia mechanisms and developing targeted therapies.
The human heart exhibits remarkable chamber-specific ion channel expression patterns that underlie the distinct electrophysiological properties of atrial versus ventricular myocardium. This comprehensive review examines the molecular architecture, biophysical properties, and functional roles of 79 ion channel subunits and related proteins across all four cardiac chambers based on quantitative transcriptomic data from non-diseased donor hearts. Understanding chamber-specific expression profiles is essential for comprehending cardiac electrophysiology, arrhythmia mechanisms, and the development of chamber-selective therapeutic strategies.
