Abstract

Purpose

Myocardial fibrosis (MF) after acute myocardial infarction (AMI) ultimately results in heart failure, which is a serious threat to human life. This study aimed to excavate critical biomarkers associated with MF after AMI.

Materials and Methods

RNA-sequencing was performed to obtain differentially expressed mRNAs (DEmRNAs), miRNAs (DEmiRNAs) and lncRNAs (DElncRNAs) in AMI and MF after AMI.

Results

Abundant DEmRNAs, DEmiRNAs and DElncRNAs were identified in AMI and MF after AMI. The ceRNA network, which contained 9 lncRNA-miRNA pairs and 9 miRNA-mRNA pairs, was acquired. In AMI, all candidate markers generally exhibited the same pattern as that in our RNA-seq results; while in MF after AMI, except for CENPB, JAK2 and hsa-miR-197-3p, the expression of the others in the qRT-PCR results exhibited the same pattern as that in our RNA-seq results.

Conclusion

We speculated that LINC00664/hsa-miR-197-3p/JAK2 and GAS6-AS1/SNHG22/hsa-miR-135a-5p/CENPB/BCL9L interaction pairs may serve as potential biomarkers in MF after AMI.
