- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Mutations in the enzymes IDH1 and IDH2 have been identified in a wide variety of tumors like glioma, chondrosarcoma, thyroid cancer, lymphoma, melanoma, and in acute myeloid leukemia. Mutated IDH1/2 produces the metabolite 2-hydroxyglutarate (2HG), which interferes with epigenetic regulation of gene expression, and thus may promote tumorigenesis.
Publication Title
Pan-mutant-IDH1 inhibitor BAY1436032 is highly effective against human IDH1 mutant acute myeloid leukemia in vivo.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
PU.1 is a key transcription factor for macrophage differentiation. Novel PU.1 target genes were identified by mRNA profiling of PU.1-deficient progenitor cells (PUER) before and after PU.1 activation. We used two different types of Affymetrix DNA-microarrays (430 2.0 arrays and ST 1.0 exon arrays) to characterize the global PU.1-regulated transcriptional program underlying the early processes of macrophage differentiation.

Description
Primary human macrophages with a HIF-1alpha or HIF-2alpha knockdown were pretreated with IL-10 for 16h and afterwards for 4h additionaly under hypoxi (1% O2), RNA was isolated usind the Qiagen RNAeasy Kit and cDNA synthesis wos done using Ambion WT Expression Kit. Expression was compared to si control under control conditions.

Description
The transcriptional regulator Rbpj is involved in T-helper (TH) subset polarization, but its function in Treg cells remains unclear. Here we show that Treg-specific Rbpj deletion leads to splenomegaly and lymphadenopathy despite increased numbers of Treg cells with a polyclonal TCR repertoire. A specific defect of Rbpj-deficient Treg cells in controlling TH2 polarization and B cell responses is observed, leading to the spontaneous formation of germinal centers and a TH2-associated immunoglobulin class switch. The observed phenotype is environment-dependent and can be induced by infection with parasitic nematodes. Rbpj-deficient Treg cells adopt open chromatin landscapes and gene expression profiles reminiscent of tissue-derived TH2-polarized Treg cells, with a prevailing footprint of the transcription factor Gata-3. Taken together, our study suggest that Treg cells require Rbpj to specifically restrain TH2 responses, including their own excessive TH2-like differentiation potential. Overall design: We isolated Treg cells from spleens of affected Treg Rbpj-deficient animals and wildtype counterparts. Total RNA was isolated and subjected to gene expression analysis using RNA sequencing

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Twenty-one genes (27 probe sets) were up-regulated in CAF, as compared with NF. Known functions of these genes relate to paracrine or intracellular signaling, transcriptional regulation, extracellular matrix and cell adhesion/migration. Ten genes (14 probe sets) were down-regulated in CAF, including the pluripotency transcription factor KLF4. Quantitative RTPCR analysis of 10 genes validated the array results. Immunohistochemical staining for three gene products confirmed stromal expression in terms of location and relative quantity. Surprisingly, the variability of gene expression was slightly higher in NF than in CAF, suggesting inter-individual heterogeneity of normal stroma.

Description
The study seeks to identify the epigenetic changes caused by exposure of to cigarette smoke condensate. To this goal human bronchial epithelial cells, BEAS-2B, were treated with 5-aza-2deoxycitidine and trychostatin A (5AzaC/TSA) subsequent to a chronic exposure (1 month) to cigarette smoke condensate (CSC). As negative control served BEAS-2B cells that were untreated or treated with CSC/DMSO for one month without the subsequent application of 5Aza/TSA.
