ABL1 and chronic myelogenous leukemia, BCR-ABL1 positive: Next, we transduced the bone marrow (BM) cells from 5‐fluorouracil (5‐FU)‐treated WT or Prmt1fl/fl mice with BCR‐ABL‐iCre‐GFP retrovirus and transplanted them into sublethally irradiated recipients to induce CML after verifying the equal transduction efficiency of BCR‐ABL‐iCre‐GFP retrovirus (Figure2A; Figure S2B, Supporting Information).
