Taking into account all cases of NSCLC, we found that 9 out of 14 lncRNAs (HAGLR, ADAMTS9-AS2, LINC00261, MCM3AP-AS1, TP53TG1, C14orf132, LINC00968, LINC00312, TP73-AS1) were downregulated in the tumor tissue compared to normal lung tissue; two lncRNAs (LOC344887and LINC00673) were upregulated and three lncRNAs (SOX2-OT, AFAP1-AS1, LOC730101) showed statistically insignificant differences (Table 3, Figure 1A). Here, LINC00261 is linked to neoplasm.
