The result showed that compared with paired paracancer tissues, lncRNA MALAT1 expression increased in HCC tissues in patients with HCC (Fig. 3A, P < 0.001), and compared with the HCC non-metastasis group, lncRNA MALAT1 expression increased in HCC tissues in HCC metastatic patients (Fig. 3B, P < 0.001), suggesting that lncRNA MALAT1 expresses high in the HCC tissues of HCC metastatic patients. Here, MALAT1 is linked to hepatocellular carcinoma.
