This study utilized RNA-sequencing to identify differentially expressed mRNAs, miRNAs, and lncRNAs in AMI and MF after AMI, and constructed a ceRNA network. The findings suggest that certain potential biomarkers may play crucial roles in MF after AMI.
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.
