Atrial fibrillation (AF) is the most frequent persistent arrhythmia. Many genes have been reported as a genetic background for AF. However, most transcriptome analyses of AF are limited to the atrial samples and have not been evaluated by multiple cardiac regions.

However, few studies have focused on species differences. Accordingly, challenges remain in studying genes that have universal functions across species and genes that determine species differences.

Here, we used a modified mRNA (modRNA) gene delivery platform to deliver a cocktail, termed 7G-modRNA, of four cardiac-reprogramming genes-Gata4 (G), Mef2c (M), Tbx5 (T), and Hand2 (H)-together with three reprogramming-helper genes-dominant-negative (DN)-TGFβ, DN-Wnt8a, and acid ceramidase (AC)-to induce CM-like cells. We showed that 7G-modRNA reprogrammed 57% of CM-like cells in vitro.
