LNCSEA 2.0 annotation analysis predicts that HCG17 in colon adenocarcinoma, MIR646HG, SBF2-AS1, HCG17, LINC01539, LINC00398, TMEM72-AS1, and ATP6V0E2-AS1 in lung adenocarcinoma, and in ATP6V0E2-AS1 in stomach adenocarcinoma, may be involved in the control of gene expression, suggesting the importance of exosomes in regulatory processes during tumorigenesis (Figure 2). The gene discussed is SBF2; the disease is lung adenocarcinoma.
