Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
5-aminolevulinic acid (ALA) is the common precursor of all biological synthezised tetrapyrroles. Inhibition of ALA synthesis results in decreased amounts of chlorophylls, heme, siroheme and phytochrome. It was previously shown that 4 out of 5 Arabidopsis mutants uncoupling nuclear gene expression from the physiological state of the chloroplast are affected in plant tetrapyrrole biosynthesis. It is common to all four mutants to show a reduced ALA formation.

Description
To analyze the impact of photosynthetic redox signals, light sources with spectral qualities that preferentially excite either Photosystem I (PSI light) or Photosystem II (PSII light) were used. The light sources have been described in (Wagner et al, Planta 2008). Strong reduction signals were induced by light shifts from PSI to PSII light (PSI-II). In order to find primary regulated genes the acclimation responses were monitored at 30 min and 60 min after a light shift. The control was continuous Psi light at the same time. We used stn7 (a thylakoid redox regulated kinase) to specifically block transduction of photosynthetic redox signal in order to compare real redox regulated with that of other light acclimation pathways.

Description
To elucidated through an unbiased manner which genes and pathways are differentially regulated during mouse colonic inflammation followed by a tissue regeneration phase. In particular, we took advantage of the widely used dextran sodium sulfate (DSS)-induced model of colitis. This model is one of the few characterized by a phase of damage followed by a phase of regeneration. Therefore, this model gave the possibility to identify also sets of genes essential in the regeneration phase, a key step towards the resolution of the inflammation. In short, mice were exposed to DSS in the drinking water for 7 days, then allowed to recover for the following 7 days. During this period, we collected colonic tissue samples every second day to then be analyzed by RNA sequencing (RNA-seq). Next, we performed a RNA-seq analysis from colonic samples throughout the experiment and computed differentially expressed genes (DEGs) taking the complete kinetics of expression into consideration for p-value estimation using EdgeR. Overall design: C57BL/6J female mice were treated with 2.5% DSS in order to induce colinic inflammation. 2-3 animals were sacrificed at different time points when the colonic tissue was collected.

Description
In our studies we were searching for the new factors engaged in mitochondrial nucleic acids metabolism under stress conditions in humans. Quantitative proteomic approach revealed C6orf203 protein as a potential new factor engaged in response to perturbed mitochondrial gene expression. We showed that C6orf203 is a mitochondrial RNA binding protein which is able to rescue diminished mitochondrial transcription in stress conditions. Overall design: The dataset corresponds to RNAseq studies and comprises experiment performed in triplicate. The aim of this study was to examine the influence of C6orf203 silencing on mitochondrial transcriptome. To this end we engineered two stable cell lines with the use of human 293 Flp-In T-Rex cells as parental. First cell line inducible expressed miRNAs silencing endogenous copy of C6orf203 gene while second one expressed additionally transgenic version of FLAG-tagged C6orf203 which contained silent mutations causing insensitivity to miRNA. We also analyzed RNA isolated from parental 293 Flp-In T-Rex cells. RNAseq libraries were prepared with the use of strand-specific library preparation procedures. RNAs were random fragmented and reverse transcribed using random oligomers as primers (dUTP-based protocol, see PMID: 29590189, PMID: 22609201; this pipeline enables analysis of RNAs (> ~100 nucleotides)). RNA was isolated from unfractionated cells using TRI-Reagent. Before preparation of the libraries total RNA was subjected to depletion of nuclear-encoded rRNAs (Ribo-Zero rRNA Removal Kit (Human/Mouse/Rat), Epicenter). Libraries were sequenced with the help of Illumina sequencing platform.

Description
IL-10 is a prototypical anti-inflammatory cytokine, which is fundamental to the maintenance of immune homeostasis, especially in the intestine. There is an assumption that cells producing IL-10 have an immunoregulatory function. However, here we report that IL-10-producing CD4+ T cells are phenotypically and functionally heterogeneous. By combining single cell transcriptome and functional analyses, we identified a subpopulation of IL-10-producing Foxp3Neg CD4+ T cells that displays regulatory activity unlike other IL-10-producing CD4+ T cells, which are unexpectedly pro-inflammatory. The combinatorial expression of co-inhibitory receptors is sufficient to discriminate IL-10-producing CD4+ T cells with regulatory function from others and to identify them across different tissues and disease models in mice and humans. These regulatory IL-10-producing Foxp3Neg CD4+ T cells have a unique transcriptional program, which goes beyond the regulation of IL-10 expression. Finally, we found that patients with Inflammatory Bowel Disease (IBD), demonstrate a deficiency in this specific regulatory T-cell subpopulation. Overall design: We carried out high troughput RNA sequencing of RNA isolated from IL-10 producing Foxp3- CD4+ T-cells, which were isolated from the spleen of mice treated with anti-CD3 antibody.

Description
After 2 and 12 weeks of treatment, we observed significant reductions of 51% and 72%, respectively, in SCORAD scores. Clinical improvements were associated with significant gene expression changes in lesional but also nonlesional skin, particularly reductions in levels of TH2-, TH22-, and some TH17-related molecules (ie, IL-13, IL-22, CCL17, S100As, and elafin/peptidase inhibitor 3), and modulation of epidermal hyperplasia and differentiation measures.
