MiR-520c-3p alleviates LPS-induced A549 cell and mice lung injury via targeting NLRC5.
2020
MicroRNAs (miRNAs) play important roles in the progression of acute lung injury (ALI). So far, little is known about the role of miR-520c-3p in ALI. In this study, the mechanism of the occurrence and development of ALI was explored. We firstly found that miR-520c-3p could inhibit the expression of NLRC5. A549 cells were treated with lipopolysaccharide (LPS) in vitro to simulate ALI cells and inducing ALI model mice. Moreover, miR-520c-3p overexpression enhanced the viability of damaged cells, inhibited LPS-induced apoptosis, and decreased LPS-induced IL-1β, IL-6 and TNF-α. In addition, the NLRC5 was a direct target of miR-520c-3p. And NLRC5 partially aggravated inflammation injury. In conclusion, miR-520c-3p alleviates LPS-induced inflammatory injury via regulating NLRC5.
