 Approximately 75 % of extraskeletal myxoid chondrosarcoma tumors (EMC) harbor a t(9;22) chromosome translocation generating an EWS/NR4A3 fusion protein that is thought to be instrumental in the tumoral process.     ///    We have performed microarray analyses of these cells and identified several genes overexpressed in the presence of EWS/NR4A3 which are also overexpressed in EMC tumors.     ///    Identification of genes regulated by the EWS/NR4A3 fusion protein in extraskeletal myxoid chondrosarcoma..
