These findings were corroborated in a second series of human HCC (n = 32; (Figure S1), which revealed significantly increased MDM4, SRF, ELK1, and ELK4 mRNA levels in human HCCs compared to paired surrounding non-neoplastic liver tissues (SL) (Figure S2A–D). This evidence concerns the gene ELK4 and hepatocellular carcinoma.
