HULC and hepatocellular carcinoma: LncSox4 promotes early tumorigenesis in liver cells through the Stat3‐Sox4 pathway11; the lncRNA HULC promotes liver‐cancer progression by inhibiting PTEN via miR‐15a17; and the lncRNA MCM3AP‐AS1 promotes HCC through the miR‐194‐5p/FOXA1 axis and is associated with poor clinical outcomes in patients with HCC.18
