CCNB1 and hepatocellular carcinoma: To explore the functional role of CCNB1 in mediating the effect of SNRPB on HCC progression, we generated four experimental groups: control (NC + shCtrl), SNRPB overexpression (SNRPB + shCtrl), CCNB1 knockdown (NC + shCCNB1), and a combination of SNRPB overexpression and CCNB1 knockdown (SNRPB + shCCNB1).
