View SamplesComparison of gene expression profiles between neuroblastoma samples and Ewing family tumor samples. RNA from native tumor samples was processed for DNA-microarray analysis using Affymetrix HG-U133A microarrays. Primary image analysis was performed using MAS 5.0 and data were scaled to an target intesity of 500.
DNA microarrays reveal relationship of Ewing family tumors to both endothelial and fetal neural crest-derived cells and define novel targets.

Novel genetic features of human and mouse Purkinje cell differentiation defined by comparative transcriptomics.
No sample metadata fields
View SamplesTo model human cerebellar disease, we developed a novel, reproducible method to generate cerebellar Purkinje cells (PCs) from human pluripotent stem cells (hPSCs) that formed synapses when cultured with mouse granule cells and fired large calcium currents, measured with the genetically encoded calcium indicator jRGECO1a. Using translating ribosomal affinity purification (TRAP) to compare gene expression of differentiating hPSC-PCs to developing mouse PCs, we found hPSC-PCs to be most similar to late juvenile (P21) mouse PCs. Analysis of mouse PCs defined novel developmental expression patterns for mitochondria and autophagy associated genes, recapitulated in hPSC-PCs. We further identified species differences in gene expression and confirmed protein expression of CD40LG in native human, but not mouse PCs. This study provides a robust method for generating relatively mature hPSC-PCs with human specific gene expression and defines novel genetic features in comparison to the first comprehensive analysis of global gene expression patterns of postnatal mouse PC development.

The cohesin acetyltransferase Eco1 coordinates rDNA replication and transcription.
No sample metadata fields
View SamplesEco1 is an acetyltransferase subunit of the cohesin complex and acts during DNA replication to establish cohesion between sister chromatids. However, cohesin has additional functions in gene expression, DNA damage repair, and higher-order organization of chromosomes. The eco1 mutant W216G disrupts acetyltansferase activity, and causes genome-wide transcriptional defects which can be suppressed by deletion of FOB1, a gene also involved in DNA replication. This experiment investigates gene expression differences between the eco1-W216G mutant, and mutants in FOB1, and RAD61 a gene involved in inhibition of cohesion establishment but mutation of which is able to suppress temperature sensitivity of the eco1-W216G mutant.

View SamplesCommon ALL (cALL) is the most frequent entity of childhood ALL and carries an early pre-B cell phenotype. Expression patterns of 25 pediatric cALL samples were analyzed by use of high-density DNA microarrays HG-U133A.
MondoA is highly overexpressed in acute lymphoblastic leukemia cells and modulates their metabolism, differentiation and survival.
