Bcr-Abl+ cells adherent to fibronectin do not accumulate cytochrome c in the cytoplasm following γ-irradiation.
Bcr-Abl+ BaF3p185 were cultured in the presence or absence of STI571/IL-3 overnight in serum-free medium on fibronectin or polylysin. Nonadherent cells were removed, selectively adherent cells were γ-irradiated with 0, 8, or 50 Gy as indicated. After a growing period of 17 hours, Western blot analysis of cytochrome c in the cytoplasmic fraction (5 μg/lane) was performed.
