摘要: Abstract Objective The purpose of this study was to find out the important lncRNA-miRNA-mRNA axis and pathway in osteosarcoma (OS) through bioinformatics analysis verify biological functions lncRNA/miRNA/mRNA OS vitro vivo assays. Methods differential expression mRNAs lncRNAs were identified microarray analysis, altered pathways by GSEA. Pearson Coefficient used analyze correlations between lncRNAs. Kaplan-Meier survival preformed using patient information GEO database. Their target miRNAs predicted Targetscan miRanda database confirmed dual luciferase reporter assay. QRT-PCR utilized detected relative expressions mRNAs, IL6R protein related proteins western blot. cell viability, migration apoptosis determined MTT assay, Transwell assay flow cytometry. Tumor formation nude mice verified influence LINC01116 vivo. Results Jak-stat signaling activated tissues. positively correlated with expression. MiR-520a-3p targeted 3’-UTR IL6R. Lower levels miR-520a-3p significantly shorter patients. up-regulated while down-regulated OS. promoted viability cells, acted as a tumor suppressor. inhibitor could rescue suppressive effects si-LINC011116 si-IL6R on development. also miR-520a-3p. Down-regulation inhibited growth mice. Conclusion targeting miR-520a-3p, thus activating promoting progression
