To further interrogate how MYCN and/or MYC protein(s) control CAMKV expression, we performed validation CHIP-sequencing for MYCN protein in the MYCN amplified neuroblastoma cell lines: COG-N-415, LA-N-5, NB-1643, and for MYC protein in the MYCN non-amplified lines: NB-69 and SK-N-SH (Figure 3C). This evidence concerns the gene STUB1 and neuroblastoma.
