Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
SMARCB1 (Snf5/Ini1/Baf47) is a potent tumor suppressor, the loss of which serves as the diagnostic feature in Malignant Rhabdoid Tumors (MRT) and Atypical Teratoid/Rhabdoid Tumors (AT/RT), two highly aggressive forms of pediatric neoplasms. Here, we restore Smarcb1 expression in cells derived from Smarcb1-deficient tumors which developed in Smarcb1-heterozygous p53-/- mice.
Publication Title
Loss of IGFBP7 expression and persistent AKT activation contribute to SMARCB1/Snf5-mediated tumorigenesis.

- Affymetrix Rat Genome 230 2.0 Array (rat2302)
Description
The objective of this study was to determine changes in gene expression within the extended amygdala following binge-like drinking by alcohol-preferring (P) rats. Adult male P rats were given 1-hr access to 15 and 30% ethanol (EtOH) three times daily for 8 weeks. Rats (n = 10/time point for EtOH and n = 6/time point for water) were killed by decapitation 1, 6 and 24 hr after the last drinking episode. Brains were extracted and rapidly frozen in isopentane in dry ice. RNA was prepared from individual micropunch samples of the nucleus accumbens shell (ACB-sh) and central nucleus of the amygada (CeA); microarray analyses were conducted with Affymetrix Rat 230.2 chips. EtOH intakes were 1.5-2 g/kg/session. Because too few genes changed at the individual time points, an overall effect, comparing the water and EtOH groups, was determined. In the ACB-sh and CeA, there were 276 and 402 probe sets for named genes, respectively, that were different between the two groups. There were 1.5- to 3.5- fold more genes up-regulated than down-regulated in both regions, with most differences between 1.1- to 1.2-fold. Although there were several significant Biological Processes categories in common between the 2 regions (e.g., synaptic transmission, neurite development), there were few genes in common between the two regions that differed between the EtOH and water groups. Overall, the results suggest that chronic binge-like alcohol drinking by P rats produces changes in the expression of genes that could alter neuronal function by different mechanisms in the ACB-sh and CeA.

- Affymetrix Zebrafish Genome Array (zebrafish)
Description
Ethanol exposure during prenatal development causes fetal alcohol spectrum disorder (FASD), the most frequent preventable birth defect and neurodevelopmental disability syndrome. The molecular targets of ethanol toxicity during development are poorly understood. Developmental stages surrounding gastrulation are very sensitive to ethanol exposure. To understand the effects of ethanol on early transcripts during embryogenesis, we treated zebrafish embryos with ethanol during pre-gastrulation period and examined the transcripts by Affymetrix GeneChip microarray before gastrulation. We identified 521 significantly dysregulated genes, including 61 transcription factors in ethanol-exposed embryos. Sox2, the key regulator of pluripotency and early development was significantly reduced. Functional annotation analysis showed enrichment in transcription regulation, embryonic axes patterning, and signaling pathways, including Wnt, Notch and retinoic acid. We identified all potential genomic targets of 25 dysregulated transcription factors and compared their interactions with the ethanol-dysregulated genes. This analysis predicted that Sox2 targeted a large number of ethanol-dysregulated genes. A gene regulatory network analysis showed that many of the dysregulated genes are targeted by multiple transcription factors. Injection of sox2 mRNA partially rescued ethanol-induced gene expression, epiboly and gastrulation defects. Additional studies of this ethanol dysregulated network may identify therapeutic targets that coordinately regulate early development.

Description
The goal of the study was to identify transcriptional correlates of SLE disease activity both at the cohort and at the individual levels. To do so, we longitudinally profiled the whole blood transcriptomes of 158 SLE patients by microarray for up to 4 years, yielding 924 SLE samples and 48 matched pediatric healthy samples. The transcriptional data are complemented by demographic, laboratory and clinical data.
