This included, for example, known tumor suppressor genes (e.g., DACH1, MGAT2, SENP6, SMAD4) that were jointly underexpressed or known cancer census genes (e.g., BCL11B, CD74, GATA3, MAFB, PDGFB) that were jointly overexpressed in all three comparisons of imatinib-resistant patients to the individual CML phases. This evidence concerns the gene BCL11B and chronic myelogenous leukemia, BCR-ABL1 positive.
