lncRNA lincFOXF1 is expressed at low levels in osteosarcoma tissues and cell lines. A, Hierarchical clustering analysis of differential expression of lincFOXF1 in sarcoma and normal tissues. B, lincFOXF1 is obviously decreased in sarcoma, as revealed by GSE17679 GEO data sets (P = 5.4e‐10). C, lincFOXF1 expression in osteosarcoma and adjacent non‐tumour tissues was analysed by qRT‐PCR (n = 45). D, lincFOXF1 expression in osteosarcoma cells, including SAOS2, MG63, MNNG/HOS Cl #5 (MNNG‐HOS), U2OS and 143B cells, compared with the normal osteoblast cell line hFOB1.19 was detected by qRT‐PCR. All experiments were performed in triplicate. Bars: SD; ^* P < 0.05 and ^** P < 0.01
