MYCN and neuroblastoma: For discovering important transcriptional regulators of NB, we first analysed the differentially expressed transcriptional regulators in 249 (TARGET) NB cases with varied status of age (<18 months vs. >18 months), MYCN amplification (with vs. without), clinical stages of International Neuroblastoma Staging System (INSS, 1+2+4S vs. 3+4) or risk classification (low vs. high).
