MYCN and neuroblastoma: To investigate whether the expression of B-MYB and MYCN is statistically significantly correlated in neuroblastoma patients, we have used three databases: Genesapiens [24] [www.genesapiens.org], Oncomine [25] [www.oncomine.org] and Oncogenomics [26] [home.ccr.cancer.gov/oncology/oncogenomics/].
