Abstract

MicroRNAs (miRNAs/miRs) are sensitive biomarkers and endogenous repressors of gene expression by decreasing mRNA stability and interfering with mRNA translation. Despite a number of investigations revealing the dysregulation of miRNA expression associated with cardiotoxicity induced by doxorubicin (Dox), perturbation of miRNAs directly resulting from Dox at early stage in cardiomyocytes and the target gene interaction remain largely unknown. In the present study, high‑throughput deep‑sequencing was used to analyze changes in global miRNA expression in H9c2 cardiomyocytes exposed to 5 µg/ml Dox for 0, 12 or 24 h. Compared with the 0‑h time point, the expression levels of 386 unique miRNAs were altered. Based on miRNA expression and fold‑change, the target genes of 76 selected miRNAs were further analyzed using gene interaction networks and pathway enrichment analysis. These miRNAs were involved in the regulation of different pathways, whose functions included apoptosis, cell proliferation, extracellular matrix remodeling, oxidative stress and lipid metabolism. These differentially expressed miRNAs included let‑7 family, miR‑29b‑3p, miR‑378‑3/5p, miR‑351‑3p, miR‑664‑3p, miR‑455‑3p, miR‑298‑3p, miR‑702‑5p, miR‑128‑1‑5p, miR‑671 and miR‑421‑5p. The present data indicated that global wide miRNA profiling in Dox‑induced cardiomyocytes may provide a novel mechanistic insight into understanding Dox‑induced heart failure and cardiotoxicity, as well as novel biomarkers and therapeutic targets.
