DNA methylation data from primary neuroblastoma tumors


ABSTRACT: Genome wide DNA methylation profiling of primary neuroblastomas. The Illumina 450k methylation array was used to obtain DNA methylation profiles across approximately 485,000 CpGs in 105 neuroblastomas. Tumors were derived from 40 low-risk, 9 intermediate-risk and 56 high-risk patients. Bisulphite converted DNA from the 105 samples were hybridised to the llumina HumanMethylation450 BeadChip

The broad clinical spectrum of neuroblastoma ranges from spontaneous regression to rapid progression despite intensive multimodal therapy. This diversity is not fully explained by known genetic aberrations, suggesting the possibility of epigenetic involvement in pathogenesis. In pursuit of this hypothesis, we took an integrative approach to analyze the methylomes, transcriptomes, and copy number variations in 105 cases of neuroblastoma, complemented by primary tumor- and cell line-derived global  ...[more]
