POLD1 knockdown affects cell cycle progression. (A) Cell cycle distribution of the MCF-7/shControl and MCF-7/shPOLD1 cells was analyzed by flow cytometry. (B) Data for the cell cycle assay results. Data points are presented as the mean ± standard error of the mean. *P<0.01, shControl vs. shPOLD1. POLD1, polymerase δ catalytic subunit gene 1; shPOLD1, short hairpin RNA targeting POLD1; shControl, control short hairpin RNA.
