Knock-out of CIBZ in ESCs delays G1/S transition.
A and B, deletion of CIBZ delays G1/S transition. The cell cycle distribution of CIBZ−/−1 ESCs were analyzed by flow cytometry with PI staining. A, representative flow cytometry profiles show percentages in each stage of the cell cycle on day 3 after seeding cells. B, graphic representation of the percentage of cells in each phase. Results are mean ± S.E. of five independent experiments. *, p < 0.05. C, Western blotting analysis showed the expression of the indicated proteins in CIBZ−/−1 ESCs. α-Tubulin served as loading controls.
