Expression of Bdbd in various cell lines caused arrest at G2/M phase. (A) DNA binding of CBF after the expression of Bdbd in various cell lines. Whole cell extracts were prepared at 48 h after infection with Ad-Bdbd and used in a DNA-binding assay. (B) Flow cytometric analysis of various cell lines at 48 h after infection with Ad-Bdbd in the presence or absence of Tc. Expression of Bdbd was induced in the absence of Tc in NIH 3T3 and Saos-2 cells, whereas it was induced in the presence of doxycycline in U2 OS cells. (C) The MOIs used were 1:3 for U2 OS cells, 1:6 for NIH 3T3 cells and 1:9 for Saos-2 cells.
