The expression of ZNF702P and SIAH1 was associated with certain low-risk characteristics in NB (stage 1 versus stage 4, P-value < 0.05; MYCN-nonamplified versus MNA, P-value < 0.05; one-way ANOVA test), whereas KIF6 was highly expressed in stage 4 and MNA NB (stage 4 versus LOC, P-value < 0.001; MNA versus MYCN-nonamplified tumors, P-value < 0.001, one-way ANOVA test, Fig 7D). This evidence concerns the gene MYCN and neuroblastoma.
