To address this idea, we examined the global protein synthesis by using an O‐propargyl‐puromycin (OP‐Puro) incorporation assay.[32] After confirming that PRMT1 was highly expressed in CML cells (Figure7A), we detected the global protein synthesis rates in BM cells from CML mice and normal mice. Here, PRMT1 is linked to chronic myelogenous leukemia, BCR-ABL1 positive.
