HNRNPA1 and chronic myelogenous leukemia, BCR-ABL1 positive: The growth-suppressive miR-320 is selectively sorted in CML EVs by RNA binding protein heterogeneous nuclear ribonucleoprotein A1 (hnRNPA1), transferred to BM-MSCs and inhibits β-catenin, thereby hindering osteogenesis, remodeling of the BM niche and promoting CML progression (79).
