ETV5 and pilocytic astrocytoma: Moreover, using the thirty-one Etv5 target genes that were differentially expressed in the murine tumors (Table 2), a large fraction of the probes for those targets were also differentially expressed (unadjusted p-values) in the two human datasets (56.1% in the pediatric pilocytic astrocytoma dataset and 40.8% of the probes in the juvenile pilocytic astrocytoma dataset; Fig 7).
