Three low‐risk lncRNAs, AC018752.1, RPL34‐AS1, and COL18A1‐AS1, had higher expression in normal tissue than in tumor tissue, and the remaining 24 high‐risk lncRNAs (AC084018.1, AC012615.6, AC114730.3, AL008718.3, LINC00342, AL136295.7, AC004148.1, AL928654.2, AL135999.1, PTOV1‐AS2, AC090589.3, AC005253.1, AF117829.1, ARHGAP27P1‐BPTFP1‐KPNA2P3, AC009948.2, LINC00115, RUSC1‐AS1, SNHG10, AL133243.3, AC245052.4, RAD51‐AS1, LINC01409, AL162586.1, and AC006435.2) were significantly overexpressed in tumor tissues (Figure 1D). Here, LINC01409 is linked to neoplasm.
