(B, C) qRT-PCR analysis of KIF20A mRNA expression level in HepG2 (B) and SK-Hep1 cells (C) transfected with si-NC or si-KIF20A. (D, E) MTS assay analysis of cell proliferation of HepG2 (D) and SK-Hep1 cells (E) transfected with si-NC or si-KIF20A. (F, G) Capsase-3 activity analysis of caspase-3 activities of HepG2 (F) and SK-Hep1 cells (G) transfected with si-NC or si-KIF20A. (H, I) Capsase-9 activity analysis of caspase-9 activities of HepG2 (H) and SK-Hep1 cells (I) transfected with si-NC or si-KIF20A.
