Further HPA analysis also demonstrated that, compared to normal liver tissues, HCC tissues had significantly higher protein levels of TOP2A, PRC1, RACGAP1, AURKA, NUSAP1, and CDCA5, while we could not obtain the protein expression of CCNB2, CDKN3, ASPM, and NCAPG of HCC from the HPA website. Here, TOP2A is linked to hepatocellular carcinoma.
