Among pediatric ALL cases, excessive upregulation of miR-128-1 is evident in t(4;11)- and TCF3-PBX1-positive cases, whereas the lowest values of miR-128-2 have been observed in IKZF1 del, PAX5 del and KMT2A-AFF1 fusion-positive cases [76,131,148,149]. Here, PBX1 is linked to acute lymphoblastic leukemia.
