MYCN and neuroblastoma: However, if WDR5 ChIP-seq data in the N-MYC-amplified Be(2)C cell line is considered there does exist some variation within N-MYC-amplified neuroblastoma cell lines as only ~250 WDR5 peaks were detected in Be(2)C cells, the majority of which included the conserved set of WDR5 targets [15].
