Additionally, we discovered that LINC00519 also showed 3‐5‐fold upregulation in lung adenocarcinoma (LUAD, another subtype of NSCLC) cells (A549 and H1299) versus normal HBE cells, which was similar to LINC00519 upregulation in LUSC cells (Figure S1A). This evidence concerns the gene LINC00519 and lung adenocarcinoma.
