Reciprocal t(9;22) ABL/BCR fusion proteins: leukemogenic potential and effects on B cell commitment..     ///    Our here presented data establish the reciprocal ABL/BCR fusion proteins as second oncogenes encoded by the t(9;22) in addition to BCR/ABL and suggest that ABL/BCR contribute to the determination of the leukemic phenotype through their influence on the lineage commitment..     ///    "Interestingly, BCR/ABL gave origin exclusively to a myeloid phenotype independently from the culture conditions whereas p96(ABL/BCR) and to a minor extent p40(ABL/BCR) forced the B-cell commitment of SL-cells and UCBC. "    ///    The leukemic potential of the ABL/BCR fusion proteins was assessed by in a transduction/transplantation model.
