Connexin43 Deficiency Leads to Ventricular Arrhythmias by Reprogramming Proline Metabolism
Advanced Science, EarlyView.The study demonstrated that connexin43 (Cx43) knockout caused arrhythmic phenotype and decreased proline content in vitro and in vivo. Mechanistically, Cx43 interacts with the amino acid transporter SNAT2 (sodium‐dependent neutral amino acid transporter), and its deficiency disrupts proline transport and metabolism.
