Figure 1. LncRNA microarray analysis and high expression of LINC00511 in OS. (A) Heatmap of lncRNA expression in OS tissues (n=6). LncRNAs were selected based on Flod change value>2 and P<0.05; the overexpressed lncRNAs are shown in red, and the downregulated lncRNAs are shown in green. (B) The expression of LINC00511 in Tumor tissues was higher than that in adjacent tissues as detected by qRT-PCR. **P<0.01 compared to the Adjacent group. (C) The expression of LINC00511 in OS cell lines, including MG-63, HOS, Saos-2 and 143B. *P<0.05 and **P<0.01 compared to the noncancerous osteoblast cell line hFOB 1.19.
