Lung adenocarcinoma (LUAD) is a predominant type of lung cancer in never-smoker patients. In this study, we identified a long noncoding RNA (lncRNA) LINC00857 that might regulate radio-sensitivity of LUAD cells. Expression of LINC00857 and baculoviral IAP repeat containing 5 (BIRC5) was determined to be upregulated in LUAD cells and tissues using qRT-PCR and western blot analysis. The correlation between LINC00857 and nuclear factor kappa B subunit 1 (NF-κB1) was verified using RNA immunoprecipitation and chromatin immunoprecipitation assays, while the binding relationship between NF-κB1 and BIRC5 was determined by dual-luciferase reporter assay. It was suggested that LINC00857 could recruit NF-κB1 in BIRC5 promoter region. BIRC5 promoter activity was repressed in response to small interfering-LINC00857 (si-LINC00857) in LUAD cells. Silencing LINC00857 or BIRC5 reduced proliferation and colony formation but enhanced apoptosis and radio-sensitivity of LUAD cells. The experiment in vivo verified the function of silencing LINC00857 on enhancing radio-sensitivity of LUAD cells. Our results reveal a functional regulatory LINC00857-NF-κB1-BIRC5 triplet in LUAD cells, suggesting LINC00857 as a potential target for LUAD treatment. This study identifies the involvement of functional regulatory LINC00857-NF-κB1-BIRC5 triplet in the radio-sensitivity of LUAD cells. Furthermore, targeting LINC00857 is highlighted as a potential strategy to reduce radio-resistance in the treatment of LUAD.
