Both HA-p73β and HA-ΔNp73β induce cell cycle arrest and apoptosis in MCF-7 cells. (A) Levels of induced expression of HA-p73β and HA-ΔNp73β in MCF-7 stable cell lines are comparable. (B and C) Both HA-p73β and HA-ΔNp73β suppress cell growth in MCF-7 cells. Approximately 105 MCF-7 cells were seeded in 60-mm plates in the presence or absence of tetracycline (2 μg/ml) to regulate the expression of HA-p73β or HA-ΔNp73β. (D and E) Both HA-p73β and HA-ΔNp73β induce cell death in MCF-7 cells. (F and G) Both HA-p73β and HA-ΔNp73β induce cell cycle arrest and apoptosis in MCF-7 cells.
