Perrotti et al. showed that in myeloid precursor 32Dcl3 cells transfected with BCR-ABL1 and in primary bone marrow cells from individuals with CML-BP, suppression of C/EBPα protein expression is due to the interaction between CEBPA mRNA with the RNA-binding protein hnRNP E2 [99]. This evidence concerns the gene ABL1 and chronic myelogenous leukemia, BCR-ABL1 positive.
