ABL1 and chronic myelogenous leukemia, BCR-ABL1 positive: Similar to NEAT1, H19, a maternal lncRNA, is expressed in CML cells with the t(9:22) translocation and its expression depends on the presence of the BCR-ABL fusion protein, since a knockdown of BCR−ABL expression led to a downregulation of H19 expression in K562 cells (92).
