Figure Lengend Snippet: Molecular basis of electrophysiological changes in MYH7 403/+ iPSC-CMs. (A) Volcano plot of gene expression changes between MYH7 +/+ and MYH7 403/+ iPSC-CMs. FDR, false discovery rate. (B) Comparison of differentially expressed genes. Boxes show the interquartile range, whiskers show the minimum and maximum, and the median is marked with a line. N =4 differentiations. (C) Typical western blots of rhythmonome proteins for MYH7 +/+ and MYH7 403/+ . Antibody signals detected on the same membrane are grouped together. Full western blots, including replicates, are provided in Fig. S4 . (D) Summary data showing fold change in expression for rhythmonome proteins.
