Except of H19, HOTAIR, LINC000982 and LINC00261, most of DElncRNAs were identified as novel lncRNAs associated with STAD, such as the most significantly up-regulated LOC105377924 (Figure 4I), the most significantly down-regulated SEMA3B-AS1 (Figure 4G), and LINC01105 (ENSG00000232044, Figure 4B), which had the highest degree with DEmRNAs in the co-expression network. The gene discussed is SEMA3B; the disease is gastric adenocarcinoma.
