LncRNA Gm12840 mediates WISP1 to regulate ischemia-reperfusion-induced renal fibrosis by sponging miR-677-5p

Abstract

Aim: We aimed to identify that long noncoding RNAs (lncRNAs) are involved in ischemia-reperfusion (IR)-induced late fibrosis of kidney and may constitute novel therapeutic strategies for acute kidney injury-induced chronic kidney disease. Materials & methods: We performed the mouse model of IR later induced renal fibrosis and analyzed lncRNA profiles using second-generation sequencing during the pathogenesis. Results: The expression levels of 43 lncRNAs and 141 lncRNAs were respectively changed significantly 7 days and 2 weeks after IR treatment. Based on the correlation analysis of the differentially expressed genes, the interaction networks of lncRNAs, miRNAs and mRNA were structured. Conclusion: LncRNA (Gm12840) could act as a sponge for miR-677-5p to mediate fibroblast activation induced by TGF-β1 via the WISP1/PKB (Akt) signaling pathway.
