Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
Flaviviruses, particularly Japanese encephalitis virus (JEV) and West Nile virus (WNV), are important causes of virus-induced central nervous system (CNS) disease in humans. We used microarray analysis to identify cellular genes that are differentially regulated following infection of the brain with JEV (P3) or WNV (New York 99). Gene expression data for these flaviviruses was compared to that induced following infection of the brain with reovirus (Type 3 Dearing), an unrelated neurotropic virus. Although several studies have described gene expression changes following virus infection of the brain, this report is the first to directly compare large-scale gene expression data from different viruses. We found that a large number of genes were up-regulated in common to infections with all 3 viruses (fold change > 2, P < 0.001), including genes associated with interferon signaling, the immune system, inflammation and cell death/survival signaling. In addition, genes associated with glutamate signaling were down-regulated in common to infections with all 3 viruses (fold change > 2, P < 0.001). These genes may serve broad spectrum therapeutic targets for virus-induced CNS disease. A distinct set of genes were up-regulated following flavivirus-infection, but not following infection with reovirus. These genes were associated with tRNA charging and may serve as therapeutic targets for flavivirus-induce CNS disease.
Publication Title
Virus-induced transcriptional changes in the brain include the differential expression of genes associated with interferon, apoptosis, interleukin 17 receptor A, and glutamate signaling as well as flavivirus-specific upregulation of tRNA synthetases.

- Affymetrix Human Genome U133A Array (hgu133a)
Description
A characteristic feature of anaplastic large cell lymphoma (ALCL) is the significant reduction of the T-cell expression program despite its T-cell origin, a finding very similar to the loss of B-cell identity of classical Hodgkin lymphoma (cHL). Previously we demonstrated that epigenetic mechanisms are active in cHL to induce this peculiar phenotype. The results show that combined DNA demethylation and histone acetylation of T-cell lines induce an almost complete extinction of the T-cell phenotype, including the down-regulation of essential T-cell receptor signalling pathway genes such as CD3, LCK and ZAP70, as well as an up-regulation of ALCL-characteristic genes. In contrast, combined DNA demethylation and histone acetylation of ALCL cells is not able to reconstitute their T-cell phenotype. This clearly demonstrates that similar epigenetic mechanisms are active in ALCL and cHL which are responsible for the extinction of their cell type characteristic phenotype.

- Affymetrix Drosophila Genome 2.0 Array (drosophila2)
Description
Gene expression is tightly linked to histone acetylation on lysine residues that can be recognized by bromodomains. The testis-specific bromodomain protein tBRD-1 is essential for male fertility and might act as a co-factor of testis-specifc TAFs. Here, we perform microarray analyses and demonstrate that tBRD-1 selectively controls gene expression in male germ cells
Publication Title
tBRD-1 selectively controls gene activity in the Drosophila testis and interacts with two new members of the bromodomain and extra-terminal (BET) family.

- Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
To investigate potential differences between strong and weak oscillators at the gene expression level we carried out a transcriptome analysis for each cell line. Our results indicate that phenotypic circadian clock differences are reflected by gene expression differences both in genes of the core network, but also in additional genes not directly associated with circadian clock functions.
