Figure 3. CK2α was essential for hepatoma cell proliferation and colony-formation.

Figure 3

A, B. Knockdown efficiency of selected CK2α-targeting siRNAs in transfected cells was evaluated by Western blot, and the MTS assay showed that silencing of CK2α suppressed proliferation of Bel-7402 (A) and HepG2 (B) cell lines. C, D. Colony-formation assays indicated decreased growth rates in CK2α-silenced Bel-7402 (C) and HepG2 (D) cell lines. All images are shown at ×200 magnification. Experiments were carried out in triplicate. Data are presented as the mean ± SD of three independent experiments. P-values were calculated using the independent Student's t-test. *P < 0.05 versus control; **P < 0.01 versus control; ***P < 0.001 versus control.
