Effect of BCR-ABL expression on γ irradiation-induced apoptosis.
UT-7 and BCR-ABL transfected cells were irradiated at 0, 2, 5, and 10 Gy and collected 24 hours later. Histograms show the average and SD for at least 3 independent experiments evaluating the apoptotic fractions quantified by flow cytometric analysis of PI iodide and annexin V-FITC–stained cells. The clones with the highest levels of BCR-ABL (UT-7-8/1 and UT-7/9) were refractory to radioinduced apoptosis.
