Targeted deletion of Puma inhibits thapsigargin-induced apoptosis. Cardiomyocytes isolated from wild-type (n = 5), puma+/− (n = 4), and Puma−/− (n = 3) mice were grown in tissue culture dishes and exposed to 3 μM thapsigargin for 48 h, or left untreated. Immunoblot analysis was performed using cleaved capase 3 and Puma antibodies. Actin is shown as a loading control. Data are representative of at least three independent experiments.
