E2F1 and neuroblastoma: Kaplan–Meier survival analysis indicated that high expression of PARP1 (P = 1.2 × 10−3 and P = 5.6 × 10−15), E2F1 (P = 2.9 × 10−5 and P = 3.9 × 10−17), MZF1 (P = 6.9 × 10−4 and P = 5.8 × 10−3), c‐Kit (P = 1.2 × 10−3 and P = 1.3 × 10−4), PRKCG (P = 1.3 × 10−2 and P = 3.3 × 10−3), or RET (P = 2.2 × 10−4 and P = 1.7 × 10−6) was associated with poor outcome of NB patients (GSE16476 and GSE62564, Figure 8C; Figure S10, Supporting Information).
