Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
KDM5A/LSD1 is an important epigenetic regulator in medulloblastoma, the most frequent brain tumor of childhood. Here, the response of ONS76 medulloblastoma cells upon siRNA-mediated knockdown of KDM5A is analysed.
Publication Title
The KDM1A histone demethylase is a promising new target for the epigenetic therapy of medulloblastoma.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Amplification of MYCN is the most prominent genetic marker of high-stage neuroblastoma, a childhood tumor originating from the neural crest. We generated a cell line (mNB-A1) from tumors developed in transgenic mouse and treated these cells with DMSO (n=6), the BRD4-inhibitor JQ1 (n=3) or the AURKA-inhibitor MLN8237 (n=3) for 24 h.
Publication Title
A Cre-conditional MYCN-driven neuroblastoma mouse model as an improved tool for preclinical studies.

Illumina HiSeq 2000
Description
We found that the midgut shows striking regional differentiation along its anterior-posterior axis. Ten distinct subregions differ in cell morphology, gene expression and aspects of Notch signaling. RNA from isolated regions that was analyzed by RNAseq revealed spatially regulated expression of hundreds of enzymes and other genes with likely tissue functions. Overall design: 10 midgut segments comprising from 1-3 subregions x 3 replicates from each segment = 30 samples

Physiological and stem cell compartmentalization within the Drosophila midgut.

- Affymetrix Maize Genome Array (maize)
Description
Microarray analysis of gene expression patterns in immature ear, seedling, and embryo tissues from the maize inbred lines B73 and Mo17 identified numerous genes with variable expression. Some genes had detectable expression in only one of the two inbreds; most of these genes were detected in the genomic DNA of both inbreds, indicating that the expression differences are likely caused by differential regulation rather than by differences in gene content. Gene expression was also monitored in the reciprocal F1 hybrids B73xMo17 and Mo17xB73. The reciprocal F1 hybrid lines did not display parental effects on gene expression levels. Approximately 80% of the differentially expressed genes displayed additive expression patterns in the hybrids relative to the inbred parents. The approximately 20% of genes that display nonadditive expression patterns tend to be expressed at levels within the parental range, with minimal evidence for novel expression levels greater than the high parent or less than the low parent. Analysis of allele-specific expression patterns in the hybrid suggested that intraspecific variation in gene expression levels is largely attributable to cis-regulatory variation in maize. Collectively, our data suggest that allelic cis-regulatory variation between B73 and Mo17 dictates maintenance of inbred allelic expression levels in the F1 hybrid, resulting in additive expression patterns.

Description
We identified genes whose expression changes between stage 8 and stage 10. We also identified genes whose expression was altered in stage 10 from temperature senstive ecdysone receptor mutant flies raised at the restrictive temperature. The experiments showed a significant number of genes that are upregulated in stage 10 depend EcR-mediated signaling. Overall design: 3 samples x 3 repeats
