Analysis of publicly available datasets (GSE14340 and GSE16476) indicated that the RBBP4 transcript levels were higher in NB than those in NC (P < 0.0001, unpaired t test), and highly expressed in NB cases with death (P = 0.0354, unpaired t test), progression (P = 0.0403, unpaired t test), or advanced INSS stages (P = 0.0062, unpaired t test, Supplementary Fig. 9c). This evidence concerns the gene RBBP4 and neuroblastoma.
