The MYCN oncogene is amplified in 20% of childhood neuroblastoma and is associated independently with poor prognosis. Alteration of the p53 tumor supressor gene, in contrast, occurs infrequently in these tumors. In this report, we described a 3-year-old girl with stage IV neuroblastoma. Molecular an
Human neuroblastoma cells frequently show amplification of the oncogene MYCN, which maps to 2p24. Previous studies have localized the DEAD box motif gene DDXl to the same chromosome band and demonstrated coamplification of DDXl and MYCN in two retinoblastoma cell lines. Recently, a high frequency of
A DEAD box gene (DDXI) characterized by a motif with a putative RNA helicase was found at elevated levels, with multiple copies, in a neuroblastorna and in some retinoblastoma cell lines in which the MYCN gene was amplified. The present study was aimed at determining whether amplification o f the DD
