Of note, the mir-302 family (hsa-mir-302-a, -b, -c and -d) which was highly expressed in embryonic stem cells, was associated with CCNB1 and MIR17HG. This indicated that mir-302 might reduce the proliferation of neuroblastoma as it did in other cancers (54, 55). The gene discussed is MIR17HG; the disease is neuroblastoma.
