TF and atrial fibrillation: To prioritize TFs that are important modulators of the CM transcriptome in individuals with AF, we correlated TF binding motif activities (from the snATAC-seq component of the scAF dataset) or TF expression levels (from the snRNA-seq component of the scAF dataset) with the AF-upregulated signature (Fig. 2e and Supplementary Table 10); similar results were obtained with the downregulated signature (Supplementary Fig. 9 and Supplementary Table 10).
