Background: Neuroblastoma (NBL) has a distinct nature in different prognostic subgroups.
Procedure: To understand the molecular mechanism of NBL's genesis and biology as well as that of the neural crest development, we constructed full-length-enriched cDNA libraries by an oligo-capping method from two different subsets of primary NBL, one with favorable biology and the other with MYCN amplification.
Results: Sequencing analysis of these libraries revealed that the expression profile was markedly different between both subsets. To identify the genes differentially expressed between the subsets, semi-quantitative RT-PCR analyses are proceeding.
Conclusion: So far, 54 transcripts have been found to be expressed at high levels in favorable NBLs, and significantly at low levels in unfavorable NBLs.
