ABCB4 and hepatocellular carcinoma: Bioinformatic comparison of the genomic data of post-PHx tumors from Mdr2-KO mice with 76 tumors from three different HCC mouse models (Supplemental Figure 5), and with 155 human HCCs (compared by synteny; Supplemental Figure 6) revealed only rare overlaps of genome amplification patterns between the PHx-induced tumors and other murine or human HCCs.
