(Submitter supplied) RNA expression profiles of 105 primary neuroblastomas derived from customized 4 x 44k oligonucleotide microarrays (Agilent Technologies). These profiles are part of an integrative study combining genomewide epigenetic profiles with transcriptome data of the same neuroblastoma cohort. Tumors were derived from 40 low-risk, 9 intermediate-risk and 56 high-risk patients.

(Submitter supplied) 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.

(Submitter supplied) Neuroblastoma is an embryonic solid tumor of neural crest origin and accounts for 11% of all cancer-related deaths in children. Novel therapeutic strategies are therefore urgently required. MYCN oncogene amplification, which occurs in 20% of neuroblastomas, is a hallmark of high risk. Here we aimed to exploit molecular mechanisms that can be pharmacologically addressed with epigenetically modifying drugs, such as histone deacetylase (HDAC) inhibitors. more...

(Submitter supplied) Single-color gene expression profiles from 3 neuroblastoma cell lines were generated using 44K oligonucleotide microarrays. To gain insights into the molecular processes occurring upon FOXP1 re-expression, we performed series of time-resolved gene expression measurements in FOXP1 and GFP transgenic neuroblastoma cell lines.

(Submitter supplied) The molecular determinants of a healthy human liver cell phenotype remain largely uncharacterized. In addition, the gene expression changes associated with activation of primary human hepatic stellate cells, a key event during fibrogenesis, remain poorly characterized. Here, we provide the transriptomic profile underpinning the healthy phenotype of human hepatocytes, liver sinusoidal endothelial cells (LSECs) and quiescent hepatic stellate cells (qHSCs) as well as activated HSCs (aHSCs) We assess the transcriptome for purified, non-cultured human hepatocytes, liver sinusoidal cells (LSECs) and quiescent hepatic stellate cells (qHSCs) as well as culture-activated HSCs (aHSCs).

(Submitter supplied) The human liver contains multiple cell types whose epigenetic patterns are undetermined. We examined the promoter methylome of purified and uncultured hepatic stellate cells (HSCs), hepatocytes (HEPs) and liver sinusoidal endothelial cells (LSECs), by methylated DNA immunoprecipitation (MeDIP) and array hybridization. Uncultured HSCs, LSECs and Heps show ~7000-8000 methylated promoters, with 60-70% similarity between all cell types. more...

(Submitter supplied) DNA methylation changes in neuroblastoma, a clinically-heterogeneous pediatric tumor, have been described essentially in promoter regions. We analyzed the DNA methylome of neuroblastoma using high-density microarrays and observed differential methylation not only in promoters but also in intragenic and intergenic regions at both CpG and non-CpG sites. These epigenetic changes showed a non-random distribution relative functional chromatin domains, and targeted development and cancer-related genes, relevant for neuroblastoma pathogenesis. more...

(Submitter supplied) It has been already reported that there are undifferentiated/proliferating neuroblasts in the postnatal sympathetic ganglia in TH-MYCN mice, a neuroblastoma model. We established suitable spheroid culture condition that selectively isolates undifferentiated neuroblasts from superior mesenteric ganligon (SMG) of TH-MYCN mice. In order to investigate the chromosomal alterations (gains or losses) of spheres derived from TH-MYCN mice, we carried out array comparative genomic hybridization. more...
