Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
We established a mouse model, in which transcription factor Tcfap2c can be activated in an inducible and reversible manner in somatic tissues, taking advantage of the tetracycline-dependent regulatory system.
Publication Title
Transgenic overexpression of Tcfap2c/AP-2gamma results in liver failure and intestinal dysplasia.

Description
Analysis of biopsy hippocampal tissue of patients with pharmacoresistant temporal lobe epilepsy (TLE) undergoing neurosurgical removal of the epileptogenic focus for seizure control. Chronic TLE goes along with focal hyperexcitability. Results provide insight into molecular mechanisms that may play a role in seizure propensity

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
Analysis of effect of long-term cryopreservation on peripheral blood mononuclear cells at gene expression level. The hypothesis tested in the present study was that long-term cryopreservation has an influence on the transcriptome profile of peripheral blood mononuclear cells. Results indicated remarkable changes in expression patterns upon cryopreservation of PBMCs, with decreasing signal intensities over time.

Description
Illumina expression microarray analysis of TCam-2, 2102EP, NCCIT, JAR, MPAF, ARZ and FS1 cells 8 and 16 h after 10 nanomolar romidepsin application. DMSO treated cells were used as controls. These data are part of the article 'A signaling cascade including ARID1A, GADD45B and DUSP1 induces apoptosis and affects the cell cycle of germ cell cancers after romidepsin treatment' (Nettersheim et al., 2016).

Description
The use of peripheral blood mononuclear cells (PBMC) for transcriptome analysis has already been proven valuable for assessing disease-associated and drug response related gene signatures. While these proof-of-principle studies have been critically important, the instability of RNA within PBMC prohibits their use in large scale multi-center trials for which samples have to be transported for a prolonged time prior RNA isolation. Therefore, a prerequisite for transcriptome analysis of peripheral blood in clinical trials will be a standardized and valid method to immediately stabilize the RNA profile after blood withdrawal. We demonstrate that the globin mRNA reduction method results in significantly improved data quality of stabilized RNA samples resulting in low intra-group variance and a detection rate of expressed genes similar to PBMC. More important, even small differences in gene expression such as observed between females and males were detected and sufficient to predict gender in whole blood samples.
