Figure 4From: Rb induces a proliferative arrest and curtails Brn-2 expression in retinoblastoma cellsComparison of Rb and p27 cell cycle effect. A. Y79 cells were mock infected (lane 1) or infected with BE-GFP, BE-GFP-Rb, or BE-GFP-p27 (lanes 2–4); and examined by western blotting for p27 expression, and for actin expression as a loading control. B. Infected cells were stained with propidium iodide and examined for cell cycle position.Back to article page
