In Adriamycin-resistant CML cells (K562), the induction of the lncRNA FENDRR (FOXF1 Adjacent Non-Coding Developmental Regulatory RNA) promotes miR-184 sponging, thereby favoring HuR-dependent MDR1 mRNA stabilization [82]. This evidence concerns the gene ABCB1 and chronic myelogenous leukemia, BCR-ABL1 positive.
