Of these lncRNAs, six were common to tumor cells, RFPL1S (p = 0.019), PPP1R26-AS1 (p = 0.008), RP11-439E19.3 (p = 0.01), CASC15 (p = 5.27 × 10–5), AC004540.5 (p = 0.00042), and CTD-2881E23.2 (p = 8.4 × 10–6), while two were unique to DTCs, ZRANB2-AS2 (p = 0.033) and LINC00511 (p = 0.03) (Figures 1B,D). Here, RFPL1S is linked to neoplasm.
