Abstract

Abstract: Background: Infantile pneumonia (IP) is a usual disease in infants and young children. The function and underlying mechanism of circZNF652 on lipopolysaccharide (LPS)‐triggered inflammatory damage in WI‐38 cells were detected in this article. Methods: WI‐38 cells were induced by dosages of LPS to construct inflammatory injury model. WI‐38 cell viability and apoptosis were detected by CCK‐8 assay and flow cytometry, respectively. CircZNF652 and miR‐181a levels were changed and detected by cell transfection and qRT‐PCR. The levels of apoptosis and JNK/p38 and NF‐κB pathways‐related proteins, as well as the level of Cox‐2 were detected by western blot. Finally, the concentrations of inflammatory factors were detected by ELISA. Results: LPS induced inflammatory injury showing as notably decreased the viability, while increased the numbers of apoptotic cells, as well as the levels of apoptosis and inflammatory factors in a dose dependent way. Besides, LPS inducement remarkably enhanced the expression of circZNF652. However, knockdown of circZNF652 remitted LPS‐triggered inflammatory damage and restrained NF‐κB and JNK/p38 pathways. Moreover, circZNF652 knockdown promoted miR‐181a expression. Whereas, miR‐181a inhibition markedly relieved circZNF652 knockdown‐induced impacts. Conclusion: Knockdown of circZNF652 remitted LPS‐triggered WI‐38 cells inflammatory damage through deactivation of NF‐κB and JNK/p38pathways by up‐regulating miR‐181a.
