A bioinformatics approach for exploring and identification of potential target genes of miR-130a-3p in doxorubicin-associated cardiotoxicity

Abstract

Doxorubicin (DOX) is considered one of the most effective chemotherapy drug and is used to treat many types of cancer. On the other hand, the effectiveness of this drug is restricted due to its adverse effects such as cardiotoxicity. However, the exact mechanism of DOX-induced cardiotoxicity has not been fully understood. To better understand the molecular mechanism of DOX-induced cardiotoxicity, this study focused on identifying a heart-specific miRNA and its target genes in the heart. Publicly available data was downloaded from the Gene Expression Omnibus (GEO) database, and differentially expressed genes (DEGs) were extracted by using the online bioinformatics tool iPathwayGuide. Using eight different prediction tools, target genes of miR-130a-3p were identified. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were performed for DEGs intersected with miR-130a-3p targets. Among the HF and non-HF groups, a total of 29 DEGs targeted by miR-130a-3p were identified. We found that SLC8A1, which is among the intersecting genes, might be a crucial gene that is shaped in impaired myocardial function and cardiotoxicity. In conclusion, the findings of the study provided new insights into the potential targets for DOX-induced cardiotoxicity diagnosis, treatment, and/or attenuation.
