Abstract

Infantile pneumonia (IP) is an acute lower respiratory infection that imposes a heavy burden on children’s health. Increasing evidence has demonstrated that long non-coding RNA (lncRNA) LINC00707 participates in the regulation of the pneumonia process. Cell proliferative ability and apoptosis were measured using Cell Counting Kit-8 (CCK-8), 5-ethynyl-2’-deoxyuridine (EdU), and flow cytometry assays. Bcl-2 related X protein (Bax), NF-kB activating protein (NKAP), p-P65, P65, p-IκBα, and IκBα protein levels were detected using western blot assay. The binding between miR-382-5p and LINC00707 or NKAP was predicted by starBase v2.0 and then verified by a dual-luciferase reporter and RNA Immunoprecipitation (RIP) assays. LINC00707 and NKAP levels were increased, and miR-382-5p was decreased in LPS-stimulated WI-38 cells. Furthermore, the silencing of LINC00707 could abrogate LPS-engendered WI-38 cell proliferation, apoptosis, and oxidative stress. LINC00707 deficiency could relieve LPS-triggered WI-38 cell damage by regulating the miR-382-5p/NKAP axis, providing a new therapeutic strategy for IP treatment.
