Western blot analysis showing DNA-PKcs and BCR-ABL expression in the human UT-7 clones, expressing variable levels of BCR-ABL.

(A) Western blot analysis showing DNA-PKcs and BCR-ABL expression in the murine Ba/F3 (B) clones, expressing increasing level of BCR-ABL (C3, low; C5, intermediate; C6, high, as previously reported12). This figure, showing a decreased expression of DNA-PK as BCR-ABL increases, is representative of 3 independent experiments. (C) Northern blot analysis showing the levels of DNA-PKcs mRNA in human UT-7 clones.
