U937p210BCR-ABL/c6 cells with inducible p210BCR-ABL expression (Tet-On) display one single bcr-abl transgene with moderate p210BCR-ABL expression in the (Doxycycline-) induced state and served as a model of CML CP [17]. The gene discussed is ABL1; the disease is chronic myelogenous leukemia, BCR-ABL1 positive.
