MZF1 and neuroblastoma: In public datasets (GSE16476 and GSE62564), MZF1‐AS1 expression was positively correlated with MZF1 levels (R = 0.395, P = 1.4 × 10−4; R = 0.662, P = 2.3 × 10−64; Figure S3B, Supporting Information), and higher in NB tissues with death (P = 1.0 × 10−2), clinical progression (P = 3.9 × 10−3), high risk (P = 2.5 × 10−3), or unfavorable histology (P = 5.2 × 10−3; Figure S3C, Supporting Information).
