Following detecting LINC01446 expressions in five GC cells and GES-1 cells, we interfered LINC01446 expressions in the SGC7901 and BGC823 cells that had high LINC01446 expression using si-LINC01446, and overexpressed LINC01446 in the MGC803 cells that had low LINC01446 expression (Fig. 2a–c). This evidence concerns the gene LINC01446 and gastric cancer.
