SOX11 and neuroblastoma: Third, we determined which of these genes showed significant correlation with SOX11 expression in 2 independent NB tumor cohorts (GSE8504717 and GSE4554718) and narrowed down the SOX11 early and late regulated gene list and established a SOX11 early (56 genes) and late (68 genes) gene signature (Fig. 4c, Supplementary Data 3).
