These analyses showed 15 genes were implicated in the prognosis of gastric cancer, including AC011374.1, AC018781.1, ADAMTS9-AS1, AL139002.1, AL391152.1, HOTTIP, FLRT1, NKX2-1-AS1, ADAMTS9-AS2, LINC00326, VCAN-AS1, SERPINE1, POU6F2-AS2, IGF2-AS, and miR-145 (Fig. 2). Here, IGF2 is linked to gastric cancer.
