Renal tubular epithelial cell apoptosis is the main mechanism of cisplatin-induced acute kidney injury. The role of microRNAs (miRNAs) in the apoptosis of renal tubular epithelial cells has been suggested, but the underlying mechanism has not been fully elucidated. We used microarray analysis to identify miR-142-5p involved in cisplatin-induced acute kidney injury. miR-142-5p was down-regulated in human renal tubular epithelial (HK-2) cells with cisplatin treatment. Notably, the overexpression of miR-142-5p attenuated the cisplatin-induced HK-2 cell apoptosis and inhibition of miR-142-5p aggravated cisplatin-induced HK-2 cell apoptosis. During cisplatin treatment, p53 was activated. The inhibition of p53 by pifithrin-α attenuated the cisplatin-induced kidney injury and up-regulated miR-142-5p expression. We also identified the Sirtuin7 (SIRT7) as a target of miR-142-5p. Furthermore, we demonstrated that the inhibition of SIRT7 prevented cisplatin-induced HK-2 cell apoptosis and decreased the expression of nuclear factor kappa B (NF-κB). Our data revealed that p53 inhibition could attenuate cisplatin-induced acute kidney injury by up-regulating miR-142-5p to repress SIRT7/NF-κB. These findings may provide a novel therapeutic target of cisplatin-induced acute kidney injury.
