Wan et al. [91] have shown that chronic myeloid leukemia cells (K562) and their secreted exosomes expressed high levels of miR-92a-3p, which inhibited the expression of CCAAT/enhancer binding protein alpha (C/EBPα) transcripts. The gene discussed is CEBPA; the disease is chronic myelogenous leukemia, BCR-ABL1 positive.
