Overexpression and knockdown of CDK2 and CCSP1 and their effects on C/EBP β phosphorylation.

BEAS-2B cells were infected with the indicated lentivirus, and CDK2, CCSP1 and phosphorylated C/EBP β and total C/EBP β were measured by western blotting 72 h later. Upper: representative blots of CDK2, CCSP1 and phosphorylated C/EBP β and total C/EBP β and β-actin are shown. Lower: the optical density of the target band divided by the optical density of the β-actin band. Data are means ± SD from at least three separate replicates.*, p < 0.05; **, p < 0.01 vs cell group or cell + Lv-NC group.
