- Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
The transcription factor FoxP3 partakes dominantly in the specification and function of FoxP3+ CD4+ T regulatory cells (Tregs), but is neither strictly necessary nor sufficient to determine the characteristic Treg transcriptional signature. Computational network inference and experimental testing assessed the contribution of several other transcription factors (TFs). Enforced expression of Helios or Xbp1 elicited specific signatures, but Eos, Irf4, Satb1, Lef1 and Gata1 elicited exactly the same outcome, synergizing with FoxP3 to activate most of the Treg signature, including key TFs, and enhancing FoxP3 occupancy at its genomic targets. Conversely, the Treg signature was robust to inactivation of any single cofactor. A redundant genetic switch thus locks-in the Treg phenotype, a model which accounts for several aspects of Treg physiology, differentiation and stability.

Description
Gangliogliomas, the most frequent neoplasms in patients with pharmacoresistant focal epilepsies, are characterized by histological combinations of glial and dysplastic neuronal elements, a highly differentiated phenotype and rare gene mutations.<br></br><br></br>Here, we have used discrete microdissected ganglioglioma and adjacent control brain tissue obtained from the neurosurgical access to the tumour of identical patients (n = 6) carefully matched for equivalent glial and neuronal elements in an amount sufficient for oligonucleotide microarray hybridization without repetitive amplification. Multivariate statistical analysis identified a rich profile of genes with altered expression in gangliogliomas.

Description
MIST1 is a bHLH transcription factor that is necessary for the maturation of gastric zymogenic cells as they differentiate from their precursor mucous neck cells. In this experiment, mucous neck cells and zymogenic cells of normal, adult C57BL/6 and MIST1 knockout mice were laser-capture microdissected in order to determine MIST1-dependent, zymogenic cell specific gene expression.

Description
The alarmins myeloid-related protein (MRP) 8 and MRP14 are the dominant cytoplasmic proteins in phagocytes. After release by activated phagocytes extracellular MRP8/MRP14 complexes promote inflammation in many diseases, including infections, allergies, autoimmune diseases, rheumatoid arthritis or inflammatory bowel disease. As receptors for the pro-inflammatory effects of human MRP8, the active component of the MRP8/MRP14-complex, Toll-like receptor (TLR) 4 and the multi-ligand receptor of advanced glycation end products (RAGE) are controversial discussed. Using a comparative bioinformatics analysis between genome-wide response patterns of monocytes to MRP8, endotoxin and different cytokines we demonstrated a dominant role of TLR4 during MRP8-mediated phagocyte activation. The relevance of this signaling pathway could be confirmed in independent cell models for TLR4 and RAGE dependent signaling in mouse and man. In addition to well-known proinflammatory functions of MRP8 our systems biology approach unraveled a novel anti-apoptotic effect of MRP8 on monocytes which was confirmed in independent functional experiments. Our data define the dominance of the TLR4-MRP8 axis in activation of human phagocytes which represents a novel attractive target for modulation of overwhelming innate immune responses.

- Illumina MouseWG-6 v2.0 expression beadchip
Description
Here, we examined mouse brain trancriptional changes 1 hour after the 10th daily i.p. treament with one of the four following treaments: i) vehicle control (45% saline, 45% PEG-400 and 10% DMSO administered at 7.5mL/kg), ii) Cpd-60, 45mg/kg , administered at 7.5mL/kg or iii) SAHA, 25mg/kg, administered at 5mL/kg) or iv) CI-994, 10mg/kg, administered at 5mL/kg. Cpd-60 is a benzamide HDAC inhibitor with selectivity for class I HDAC subtypes HDAC1 and HDAC2; CI-994 is a benzamide inhibitor with selectivity for HDACs1,2 and 3; SAHA is a hydroxamic acid HDAC inhibitor with selectivity for class I HDAC subtypes 1,2, and 3 and the class II HDAC subtype HDAC 6. We examined transcript differences using the Illumnia WG-6 2.0 whole genome expression array and profiled 3 specific brain regions (prefrontal cortex, nucleus accumbens, hippocampus) from each of 36 mice (n=6 mice / treatment group) . For application to array chips, we pooled two biological replicates from like treatment and brain region-groups such that 36 samples were applied in total: 4 treatment groups x 3 brain regions per treament group x 3 pools of two samples each for each treatment/brain region.
