CTCF and neuroblastoma: Moreover, mining of a public NB dataset (GSE45547) revealed that high expression of hnRNPU (P = 2.2 × 10−10), CTCF (P = 1.8 × 10−4), CXCR4 (P = 2.5 × 10−3), or TPBG (P = 4.5 × 10−2) and low expression of CLU (P = 3.1 × 10−3) or UACA (P = 3.2 × 10−2) was associated with poor outcome of patients (Fig. 6d).
