TranscriptomicsTranscription profiling of neuroblastoma tumors with and without MYCN amplification
Purpose: Clinical courses of neuroblastomas (NBs) range from rapid progression with fatal outcome despite intensive multimodality therapies to spontaneous regression. Amplified MYCN oncogene defines a subgroup with poor outcome. However, a substantial number of MYCN single-copy NBs exhibits an aggre...

TranscriptomicsTranscription profiling of human neuroblastoma cells with and without MYCN oncogene induction and doxorubicin treatment
Purpose: Clinical courses of neuroblastomas (NBs) range from rapid progression with fatal outcome despite intensive multimodality therapies to spontaneous regression. Amplified MYCN oncogene defines a subgroup with poor outcome. However, a substantial number of MYCN single-copy NBs exhibits an aggre...

TranscriptomicsBone morphogenetic protein-7 is a MYC target with pro-survival functions in childhood medulloblastoma
Medulloblastoma (MB) is the most common malignant brain tumor in children, among whom overexpression or amplification of MYC oncogenes has been associated with poor clinical outcome. Although the MYC functions during normal development and oncogenesis in various systems have been extensively investi...

ProteomicsIncreased levels of the mitochondrial import factor Mia40 can prevent the aggregation of polyQ proteins in the cytosol
The formation of protein aggregates is a hallmark of neurodegenerative diseases. Observations on patient material and model systems demonstrated links between aggregate formation and declining mitochondrial functionality, but the causalities remained unclear. We used yeast as model system to analyze...

TranscriptomicsMYCN and HDAC2 cooperate to repress miR-183 signaling in neuroblastoma.
MYCN is a master regulator controlling many processes necessary for tumor cell survival. Here, we unravel a microRNA network that causes tumor suppressive effects in MYCN-amplified neuroblastoma cells. In profiling studies, histone deacetylase (HDAC) inhibitor treatment most strongly induced miR-183...

TranscriptomicsGRHL1 acts as a tumor suppressor in neuroblastoma and is negatively regulated by MYCN and HDAC3
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 ...

TranscriptomicsRNA expression data from primary neuroblastoma tumors
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 der...
