SPOCK1 and hepatocellular carcinoma: Overexpression of SPOCK1 in HCC cells was achieved by transfection, si‐SPOCK1 inhibited the expression of SPOCK1 and the high expression of SPOCK1 could be rescued by miR‐139‐5p, miR‐940 and miR‐193a‐5p (Figures 6A & 7A); the protein expression of SPOCK1 was similar with tendency of SPOCK1 mRNA expression (Figure 6B,C).
