Interestingly, miR-124 was upregulated in NB3, a MYCN-amplified neuroblastoma cell line [36], which is consistent with a recent report showing miR-124 upregulation in MYCN-amplified neuroblastoma when compared to nine other pediatric solid tumors including rhabdomyosarcoma and non-MYCN-amplified neuroblastoma [43]. This evidence concerns the gene MYCN and neuroblastoma.
