CCNB1 and hepatocellular carcinoma: Some critical genes were located in these modules, including cycling B1 (CCNB1), SEC62 homolog (S. cerevisiae) (SEC62), and baculoviral IAP repeat-containing 3 (BIRC3) (Figure 1D), which had the highest DiffK(i) values, suggesting that they probably play important roles in the pathogenesis of HCC recurrence.
