MALAT1 and hepatocellular carcinoma: To explore whether lncRNA MALAT1 can promote the metastasis of HCC through peripheral vascular infiltration by inhibiting miRNA-613 expression in HCC cells, miRNA-613 inhibitor was added on the basis of knocking down lncRNA MALAT1, and the cells were divided into three groups (including inhibitor-NC, lncR-inhibitor, and lncR/miR613-inhibitor groups) and miRNA-613 expression in HCC cells was detected by qRT-PCR.
