Analysis of apoptosis in Pml+/+ and Pml-/- MEFs treated with 2.5 or 5.0 µg/mL cis-pt by subdiploid peak analysis. Average of 3 independent experiments ± SD is shown.
Pml+/+ and Pml-/- MEFs were harvested 0 and 2 hours after UV irradiation (60 J/m2). Nuclear extracts were tested for DNA binding activity to a jun2 CRE site. Supershift experiments were performed by using antibodies against c-Jun and ATF-2. Sp1 binding activity was measured as control of loading. Data shown are representative of 3 independent experiments.
