For microRNAs co-expressed with PCDH17, some of them were previously reported to be negatively associated with the unfavorable prognostic factors in AML-that is, MDR1 (i.e., miR-381, miR-485, and miR-495) [45], BAALC (miR-10b) [47], and ERG (miR-196a) [48], further supporting the negative prognostic significance of deregulated PCDH17. Here, PCDH17 is linked to acute myeloid leukemia.
