Genes associated with ER stress (e.g., ATF4, NUPR1, DDIT3, TRIB3, CHAC1, SESN2, HERPUD1) were upregulated and genes related to cardiomyopathy and sarcomeric structure (e.g., MYH7, SYNPO2L, LDB3, ACTN2, MYLK3) were downregulated by afatinib, sorafenib, or high-dose ponatinib. This evidence concerns the gene DDIT3 and cardiomyopathy.
