Genome-wide analysis of long noncoding RNAs and mRNAs associated with contrast-induced acute kidney injury
Purpose:little is known about the roles of lncRNA in the pathogenesis of contrast-induced acute kidney injury (CI-AKI). Here, we compared the expression profiles of lncRNAs and mRNAs in kidney tissue between CI-AKI rats and controls. Methods:Based on a reliable CI-AKI rat model, we sought to investigate the roles of lncRNA in the kidney injury following intra-arterial contrast exposure by RNA sequencing. Results: We identified 88 differentially expressed known and novel lncRNAs at 12 hours following intra-arterial iodinated contrast medium injection. Functional enrichment analysis implied that these lncRNAs were potentially associated with oxidative stress and DNA damage response. Conclusions:These prefound findings provide the first evidence of lncRNA in the development of CI-AKI. Overall design: Three-month-old male Sprague-Dawley rats were used in this study. Kidney lncRNA profiles of CI-AKI rats and controls were generated by deep sequencing.
