All these miRNAs have been related to myeloproliferative disorders and leukemia.39, 40, 41 Moreover, the miR-17-5p/20a/106a cluster has been previously shown to repress AML1 translation, while miR-125b represses VDR and miR-155 represses C/EBPβ. This evidence concerns the gene RUNX1 and myeloproliferative disorder.
