Whereas the gene expressions of ATP7A, SLC25A3, SCO2, COA6, TMEM199, ATP6AP1, LIPT1, DLAT, PDHA1, MTF1, ACP1, FDX2, NUBP2, CIAPIN1, ISCA2, and NDOR1 in HCC tissues were prominently higher than their surrounding tissues, and the differences were all statistically significant (P < 0.001, Figure 2). The gene discussed is MTF1; the disease is hepatocellular carcinoma.
