Resistance to Atrial Fibrillation Domestication and Mitochondrial Dysfunction in Sheep: a potential key role of the TCA Cycle and mitochondrial redox state

Guido Caluori, Stanley Nattel, Benoı̂t Pinson…·Philippe Pasdois

This study compares mitochondrial function and TCA cycle activity in sheep resistant to atrial fibrillation (AF) versus those that develop stable AF, finding differences in redox state and energy metabolism.

Cell-Type-Resolved Transcriptomics Defines Stable and Accessible Markers of the Cardiac Purkinje Fiber in Sheep and Human Translation

Sabine Charron, Néstor Pallares‐Lupon, Marion Constantin…·Richard D. Walton

Laser-capture RNA-seq of sheep Purkinje fibers yields a 331-gene enriched panel; thirteen of sixteen ranked candidates confirmed by RT-qPCR, and CNTN5 is Purkinje-enriched in sheep and human.

Structural Characterization of Cardiac Purkinje Fibers Using Inhomogeneous Magnetization Transfer (ihMT): A proof of Concept MRI-Histology Approach

Arash Forodighasemabadi, Evgenios Kornaropoulos, Marion Constantin…·Julie Magat

This paper uses ihMT MRI to differentiate subregions of cardiac Purkinje fibers in sheep hearts, showing higher ihMTR in free-running PF compared to insertion points and myocardium, with histology confirming collagen differences.
