Abstract

Long non‑coding RNAs (lncRNAs) have been identified as a class of regulatory RNAs that participate in both physiological and pathological conditions, including acute kidney injury. However, the roles of lncRNA dysregulation in the pathogenesis of contrast‑induced acute kidney injury (CI‑AKI) are largely unknown. In the present study, the expression profiles of lncRNAs in kidney tissue were compared between rats with CI‑AKI and controls using high‑throughput RNA sequencing. In total, 910 differentially expressed (DE) lncRNAs (DElncRNAs), including 415 downregulated and 495 upregulated lncRNAs, were identified at 12 h after intra‑arterial iodinated contrast medium injection (fold change ≥2; P<0.05). Eight DElncRNAs were further selected and validated using reverse transcription‑quantitative polymerase chain reaction. A previous study defined microRNA (miRNA) and mRNA expression changes in the same CI‑AKI model. In the present study, a lncRNA‑mRNA co‑expression network comprising 349 DElncRNAs and 202 DEmRNAs was constructed. The function of these DElncRNAs was mainly associated with oxidative stress and inflammation. Additionally, lncRNA‑associated competing endogenous RNA (ceRNA) analysis revealed a network comprising 40 DElncRNA nodes, 5 DEmiRNA nodes and 59 DEmRNA nodes. Among which, the carnosine dipeptidase 1‑specific and the transmembrane protein 184B‑specific networks were likely to be associated with CI‑AKI. The results of the present study revealed the expression profile and potential roles of lncRNAs in CI‑AKI, and provide a framework for further mechanistic studies.
