A review of the literature revealed that CCNB2 expression is increased in HCC tissues compared to adjacent nontumor tissues [33], and CCNB2 is a target molecule following knockdown of XPOT [34], TPX2 [35], KPNA2 [36], and TMEM9 [37]. The gene discussed is KPNA2; the disease is hepatocellular carcinoma.
