Description
RNA-seq was performed to assess gene expression alterations by the addition of serial oncogenic hits (mutant-IDH1, P53 knockdown and ATRX knockdown) in human neural stem cells. Overall design: All RNA-seq was performed in duplicates, there are four conditions total. Vector NSCs are the control line and have an empty mCherry vector and a scramble shRNA vector. One hit NSCs express mutant-IDH1 and have a scamble shRNA vector. Two-hit NSCs express mutant IDH1 and have p53 knockdown. Three-hit NSCs express mutant-IDH1, P53 knockdown and ATRX knockdown.

Description
Foxp3+Tregcells are essential modulators of immune responses but under specific conditions can acquire inflammatory properties and potentially contribute to disease pathogenesis. Here we show that the transcription factor Blimp1 is a critical regulator of Foxp3+Treg functional plasticity. The intrinsic expression of Blimp1 was required to prevent Treg from producing Th17-associated cytokines and acquiring an inflammatory phenotype while preserving Foxp3 expression. Mechanistically, Blimp1 acts as a direct repressor of the Il17a/Il17f genes in Foxp3+Treg and binding of Blimp1 at this locus is associated with altered chromatin status, reduced binding the co-activator p300, unaltered binding of the Th17-asssociated transcription factor RORt and more abundant binding of IRF4, which was required for the production of IL17A in Blimp1-deficient Foxp3+Tregcells, as shown by IRF4 siRNA-mediated knockdown. Consistent with their capacity to produce inflammatory cytokines, Blimp1-deficient Foxp3+Treg exacerbate Th17-mediated inflammation in vivo indicating that Blimp1 is required to prevent Treg cells from acquiring pathogenic properties

Description
Peripheral arterial disease (PAD) is a relatively common manifestation of systemic atherosclerosis that leads to progressive narrowing of the lumen of leg arteries. Circulating monocytes are in contact with the arterial wall and can serve as reporters of vascular pathology in the setting of PAD. We performed gene expression analysis of peripheral blood mononuclear cells (PBMC) in patients with PAD and controls without PAD to identify differentially regulated genes. We identified 87 genes differentially expressed in the setting of PAD; 40 genes were upregulated and 47 genes were downregulated. We employed an integrated bioinformatics pipeline coupled with literature curation to characterize the functional coherence of differentially regulated genes. Notably, upregulated genes mediate immune response, inflammation, apoptosis, stress response, phosphorylation, hemostasis, platelet activation and platelet aggregation. Downregulated genes included several genes from the zinc finger family that are involved in transcriptional regulation. These results provide insights into molecular mechanisms relevant to the pathophysiology of PAD.

Description
Small RNAs were deep sequenced from the liver and spleen of adult mice in an effort to identify somatic piRNAs. Following sequencing of all small RNAs, known non-coding RNAs were computationally removed from the dataset. The remaining RNAs were then mapped to the genome and analyzed for sequence characteristics (5'' base, length) typical of known piRNAs. To determine if any of the identified small RNAs were MIWI2 dependent, we deep sequenced small RNAs from liver and spleen of MIWI2 KO mice and analyzed them as above. Overall design: We deep sequenced small RNAs from the liver and spleen of one WT mouse and one MIWI2 knock-out mouse. We then trimmed sequencing adapters and removed known ncRNAs (rRNA, tRNA, snoRNA, snRNA, miRNA) from the dataset before aligning reads to the mm9 assembly of the mouse genome.

Description
RNA-sequencing was conducted to profile the transcriptome of the post-ischemic mouse cortex at multiple reperfusion time-points. RNA was isolated from sham and middle cerebral artery occlusion (MCAO)-operated mice at different reperfusion time points (6 h, 12 h or 24 h; three independent biological replicates per group), converted into cDNA libraries, and used for Illumina deep sequencing on a NexSeq500 instrument. The sequencing reads that passed quality filters were analyzed at the transcript isoform level based on the Tuxedo software package. On average 40.6 million reads were obtained from each sample and genome mapping was on average 82.9% for all samples. We detected 20,748 genes and 56,586 isoforms in the sham group; 22,192 genes and 60,023 isoforms in the 6 h group; 21,771 genes and 59,539 isoforms in the 12 h group; and 21,576 genes and 59,020 isoforms in the 24 h group. Our study represents the first detailed analysis of post-stroke mouse cortex transcriptomes generated using RNA-sequencing technology. Overall design: Genome-wide transcriptomic profiles of healthy and post-ischemic mouse cortices at various reperfusion time-points (6 h, 12 h, or 24 h) were generated using Illumina sequencing.

Description
Purpose:We have the first-reported set of glial-specific transcripts utilizing the Ribotag model. We use this model to explore glial changes in DNBS-induced inflammation and neurokinin-2 receptor (NK2R) antagonism. Methods: Actively translated mRNA profiles of the distal colon myeneteric plexi of Rpl22(+/-)Sox10(+/-) male and female mice 8-10 weeks old were obtained utilizing the HA-tagged ribosomal immunoprecipitation and downstream RNA extraction. Samples meeting RNA quality standards by 18S and 28S rRNA peaks by 2100 Bioanalyzer and RNA 6000 Nano LabChip Kit (Agilent) were deep sequenced with the Illumina HiSeq 4000. Results: We mapped approximately 30-50 millions reads per sample to the mouse genome (v88) and identified approximately 100K ribosome-associated transcripts, with Tuxedo workflow, in distal colon glial cells with DNBS-induced inflammation and NK2R antagonism and their respective controls. Of these transcripts, changes in biological processes associated with inflammation and other important enteric nervous system communications between samples have been identified. Conclusions: Our study demonstrates the first use of the Ribotag model to provide glial cell-specific actively-translated mRNA changes in DNBS-induced inflammation with and without functional NK2R signalling. Overall design: Distal colon glial mRNA samples from Ribotag Rpl22(+/-)Sox10(+/-) mice administered either saline or DNBS and DMSO vehicle or NK2R antagonism.
