LINC01089 and gastric cancer: In order to study the expression characteristics of LINC01089 in GC tissues, the GEPIA database (http://gepia.cancer-pku.cn/) was used to perform bioinformatics analysis, and it was found that LINC01089 was differentially expressed in GC tissues and normal tissues; moreover, its expression was markedly lower in GC tissues (Fig. 1a).
