ABL1 and chronic myelogenous leukemia, BCR-ABL1 positive: As determined by GFP expression, the three transduced melanoma cell lines, 624.Mel 38, SK.Mel 37 and LB373.Mel, expressed comparable levels of ABL-minigene-E255V, whereas the transduced CML cell line, BV173, had a lower level of expression (Figure 3B).
