Anne Berit Johnsen

Anne Berit Johnsen is an Associate Professor at the Norwegian University of Science and Technology (NTNU), affiliated with the Department of Teacher Education. Her research focuses on cardiac electrophysiology, particularly the molecular mechanisms underlying sinus bradycardia and ion channel remodeling induced by exercise training. She investigates the role of microRNAs (e.g., miR-423-5p) and transcription factors (e.g., Nkx2.5) in regulating pacemaking ion channels like HCN4, which contribute to heart rate adaptations in athletes and potential implications for sinus node dysfunction. Her work includes studies on human athletes and rodent models, demonstrating how miRNA dysregulation impacts heart rate and ion channel expression. Despite her academic role, no explicit information on educational background, grants, or student advisees is provided in the text.

Research interests include the interplay between exercise physiology, microRNA regulation, ion channel dynamics, and their clinical relevance in cardiovascular conditions. Findings from her studies suggest miR-423-5p as a therapeutic target for pathological sinus node dysfunction in veteran athletes, highlighting novel pathways in cardiac electrophysiological adaptation.

No scientific awards or grants are explicitly mentioned in the text. Collaborations with institutions like the Institute of Circulation and Imaging (as inferred from her co-authored publication) are noted, but her primary affiliation remains the Department of Teacher Education at NTNU.
