PVT1 and Ewing sarcoma: Data mining of publicly-available databases which contain PVT1 expression along with annotated clinical parameters was performed for wilm's tumor (n = 148, R2 ID:ps_avgpres_wilmsocga148_u133a), neuroblastoma (n = 476, GSE45547), mantle cell lymphoma (n = 122, GSE93291), ewing's sarcoma (n = 52, GSE17679), osteosarcoma (n = 88, GSE42352), and pediatric glioma (n = 47, SE19578), and revealed that, in neuroblastoma, the expression of PVT1 could have prognostic value (Figure 3).
