In addition, the expression of these six candidate lncRNAs in HCC and nontumor tissues in other GEO RNA‐sequencing datasets (GSE77314, GSE94660, and GSE124535) confirmed the higher expression of most candidate lncRNAs in tumor tissues, save for DLEU2 and NEAT1 in GSE77314 and NEAT1 in GSE94660 (Fig. 2B). The gene discussed is DLEU2; the disease is hepatocellular carcinoma.
