lncRNA MALAT1 expression in HCC cells was detected by qRT-PCR, showing that lncRNA MALAT1 expression decreased in the lncR-inhibitor group compared with the inhibitor-NC group (Fig. 4A, P < 0.001), indicating the success of the construction of the lncRNA MALAT1 silencing model. Here, MALAT1 is linked to hepatocellular carcinoma.
