Figure 1. LncRNA LOC100129620 is upregulated in osteosarcoma lung metastasis tissue and osteosarcoma cell lines. (A) Heatmap analysis of the changes of gene expression in osteosarcoma bone primary tissues and osteosarcoma lung metastases. (B) LOC100129620 expression was analyzed by qRT-PCR in osteosarcoma bone primary tissues and osteosarcoma lung metastases. Primary tissues, n = 10; lung metastases, n = 10. (C) The expression of LOC100129620 in hBMSCs, hFOB1.19, and osteosarcoma cell lines (U2OS, MG63, HOS, and Saos-2) was detected by qRT-PCR. (D) The nuclear and cytoplasmic levels of LOC100129620 in U2OS cells were detected by qRT-PCR. GAPDH and lncRNA MALAT1 were used as controls. (E) The expression of LOC100129620 in U2OS cells was detected by in situ hybridization. Blue indicates nuclei (stained with DAPI), and red indicates LOC10012960. Scale bar, 20 μm. Statistical analysis was conducted using Student’s t-test. Values are means ± SD. *P < 0.05 and **P < 0.01.
