Some PAX3 targets, such as genes involving melanogenesis (DCT and TYRP1) and myogenesis (MYF5 and MYOD), were not expressed in the two neuroblastoma cells whereas others (RET, MET, PTEN and STX1) were expressed but not altered by PAX3 silencing 4 (Table S4). This evidence concerns the gene PTEN and neuroblastoma.
