Dox treatment upregulated cardiotoxicity-related genes. A Volcano plot showing the expression alteration of genes in rat cardiomyocytes upon Dox treatment. B Histogram showing the number of down-regulated and up-regulated genes with different fold change in cardiomyocytes upon Dox treatment. C Heatmap showing the genes with both increased H3K27ac signal and increased mRNA expression in rat cardiomyocytes upon Dox treatment. D Gene ontology analysis showing the biological processes for the genes with both increased H3K27ac signal and increased mRNA expression in rat cardiomyocytes upon Dox treatment. E The representative genes with both increased H3K27ac signal and increased mRNA expression in cardiomyocytes upon Dox treatment, several genes are reported to be associated with Dox-induced cardiotoxicity including Fas, Bax and Bnip3, other genes are potentially associated with cardiotoxicity. F, G H3K27ac signal nearby Bnip3 and Egr-1 (F) and their mRNA expression (G) in cardiomyocytes upon Dox treatment with two replicates. H Gene ontology analysis showing the biological processes for the upregulated genes in cardiomyocytes from an in vivo model upon Dox treatment (GSE223698). I Expression of apoptotic and cell death associated genes in cells from mouse heart upon Dox treatment for 24 h. J Compared to the Dox group, volcano plot showing the expression alteration of genes in cardiomyocytes upon Dox + C646 treatment. K Compared to the Dox group, the percentages of down-regulated and up-regulated genes after Dox + C646 treatment. L Compared to the Dox group, the percentage of down-regulated and up-regulated genes among Dox_H3K27ac-upregulated genes after Dox + C646 treatment. M Gene ontology analysis showing the biological processes for the Dox_H3K27ac-upregulated genes with decreased mRNA expression in cardiomyocytes upon Dox + C646 treatment
