To strengthen these findings, we transduced BM and spleen cells from primary WT or Prmt1 KO CML mice with pCDH‐vector, pCDH‐PRMT1WT or pCDH‐PRMT1E153Q lentivirus and transplanted them into the secondary recipients to induce CML (Figure3A). Here, PRMT1 is linked to chronic myelogenous leukemia, BCR-ABL1 positive.
