As shown in Figure 3, the mRNA expression levels of (Fig. 3A) FOXM1, (Fig. 3B) AURKA, (Fig. 3C) CCNA2, (Fig. 3D) CCKN3, (Fig. 3E) MKI67, (Fig. 3F) EZH2, (Fig. 3G) CDC6, (Fig. 3H) CDK1, (Fig. 3I) CCNB1, and (Fig. 3J) TOP2A were significantly upregulated in HCC tissues (P < .01) compared to those in normal liver tissues. The gene discussed is TOP2A; the disease is hepatocellular carcinoma.
