CCNB2 and hepatocellular carcinoma: The results showed that the transcriptional levels of TOP2A, CCNB2, PRC1, RACGAP1, AURKA, CDKN3, NUSAP1, CDCA5, ASPM, and NCAPG were significantly overexpressed in HCC tissue when compared with the normal controls (Figures 4A–K), indicating their potential oncogenic effects.
