GAS6 and neoplasm: An overview of the analysis pipeline is presented in Figure 1A. Five lncRNA candidates were selected; two, EWSAT1 and GAS6-AS1, were selected based on a comprehensive literature search on novel lncRNAs with no previous association with GC development, but deregulated in other tumor entities (Table S1); and three, PCAT18, DANCR, and LINC01133, were selected based on the analysis of GC datasets from GEO.
