    A) Number of Pol II ChIP-seq and input sequencing reads aligned to the mouse genome (experimental) or the human genome (spike-in control). Scale factors are computed by spike-in control reads and sequencing depths and used to normalize Pol II ChIP-seq signals. All data in are derived from mice at 2 weeks post tamoxifen. B) Pol II ChIP-seq read coverage in all mouse genes stratified by gene-body Pol II coverage. Genes with Pol II coverage greater than or equal to 100 (2 in Log 10 ) were considered Pol II-bound (11,942 genes). C) Pol II ChIP-seq read coverage in all human genes, derived from the spike-in control chromatin. D) Gene-body Pol II ChIP-seq read coverage between every pair of biological replicates. E) Principal Component Analysis (PCA) of gene-body Pol II coverage in 11,942 Pol II-bound protein-coding genes. F) Cumulative fraction of 1,759 Pol II-lost genes and all other genes (y-axis) along the scale of differential gene expression between Lmna CKO hearts and wild-type hearts (x-axis). P, Kolmogorov-Smirnov test p -value comparing log 2 fold change of gene expression between Pol II-lost genes and all other genes. G) Gene expression state of Pol II-lost genes, Pol II-gained genes, and all other genes in the cardiomyocyte population in Lmna CKO (n=3) versus WT (n=3) hearts derived from single-nucleus RNA-seq in En et al. 2024. P, DESeq2 p -value. H) Same as F, but along the scale of differential gene expression between Lmna CKO and wild-type pseudo-bulk cardiomyocytes from the single-nucleus RNA-seq. P, Kolmogorov-Smirnov test p -value comparing log 2 fold change of gene expression between Pol II-lost genes and all other genes.
