CUX1 and neuroblastoma: Among 60 MAZ target genes derived from RNA‐seq results and ChIP‐X analysis, the expression of CUX1, S100 calcium‐binding protein A9 (S100A9), mucin 4 (MUC4), Kruppel‐like factor 10 (KLF10), or thioredoxin‐interacting protein (TXNIP) was significantly correlated with that of MAZ in 54 NB cases (Appendix Fig S7B).
