Description
RNAseq analysis of cell lines with ADAR1-p150 and ADAR1-p110 knock-outs and primary human tissue samples (from GSE57353 and GSE99392 data sets) to identify sites of ADAR1 editing Overall design: 12 samples: 3 cell lines (HeLa, HeLa-p150KO, HeLa-ADAR1KO) with four conditions each (no treatment, MeV-vac2(GFP)-infected, MeV-CKO(GFP)-infected, IFNA/D-treated). One biological replicate per sample. In addition, raw data files of 9 samples from series GSE57353 and GSE99392 were re-analyzed using the same data processing pipeline.
Publication Title
Extensive editing of cellular and viral double-stranded RNA structures accounts for innate immunity suppression and the proviral activity of ADAR1p150.

Description
The classical concept of bone marrow-derived mesenchymal stem cells (BM-MSC), intended as a uniform, broad potent population, is progressively being substituted by the idea that the bone marrow harbors heterogeneous populations of non-hematopoietic stem cells. This in vivo heterogeneity is also amplified by the different experimental strategies used to isolate/culture them. Among the exogenous factors described to affect MSC in vitro growth, basic-fibroblast growth factor (bFGF) is one of the most common growth factors used to expand stem cells. Moreover, it has been reported that its signaling is associated with the mainteinance of stemness of a variety of stem cells, included MSC. Using an ectopic model of bone regeneration, we have previously described that the implantation of cells with different commitment levels, differentially influences the capacity to recruit host cells, activating endogenous regenerative mechanisms. Due to its properties, we here demonstrate that the addition of bFGF to primary BM cultures, leads to the selection of specific subpopulations able to induce a different host regenerative response, when in vivo implanted in association with suitable ceramic scaffolds. Moreover, taking advantage of a multiparametric and comparative genomic and proteomic approach, it has been evaluated how different culture conditions combine to bring about appreciable changes in the secretome of the cells, that consequently influence their in vivo regenerative behaviour. The full comprehension of the regulatory mechanisms that rule the host response depending on the type and differentiative stage of the transplanted cells could help us to develop novel clinical strategies where host cells could directly contribute to regenerate the appropriate tissue.

Description
Whole-genome expression studies in peripheral tissues of patients affected by schizophrenia (SCZ) can provide new insights into the molecular basis of the disorder and innovative biomarkers that may be of great usefulness in the clinical practice. Recent evidence suggests that skin fibroblasts could represent a non-neural peripheral model useful to investigate molecular alterations in psychiatric disorders.

Description
Huntington''s Disease (HD) is a fatal neurodegenerative disorder caused by an extended polyglutamine repeat in the N-terminus of the huntingtin (Htt) protein. Reactive microglia and elevated cytokine levels are observed in the brains of HD patients, but the extent to which neuroinflammation results from extrinsic or cell-autonomous mechanisms is unknown. Furthermore, the impact of microglia activation on the pathogenesis of HD remains to be established. Using genome-wide approaches, we show that expression of mutant Htt in microglia promotes cell-autonomous pro-inflammatory transcriptional activation within microglia by increasing the expression and transcriptional activities of the myeloid lineage-determining factors PU.1 and C/EBPs. Elevated levels of PU.1 and its target genes are observed in the brains of mouse models and HD individuals. Moreover, mutant Htt expressing microglia exhibit an increased capacity to induce neuronal death ex vivo and in vivo in the presence of sterile inflammation. These findings suggest that expression of mutant Htt in microglia may contribute to neuronal pathology in Huntingtin disease. Overall design: RNA-Seq and ChIP-Seq for PU.1, C/EBP, and H3K4me2 in BV2 cells and RNA-Seq in primary microglia and macrophages

There is much evidence that T cells may be activated via mechanisms which act independently of direct TCR ligation. Despite this, the question of whether such forms of bystander T cell activation occur during immune responses is hotly debated.

Purpose: to identify genes aberrantly expressed upon myocardial ablation of Hif1a Methods: a floxed Hif1a allele was deleted in mouse embryonic hearts using a NXK2.5Cre line. Total RNA was extracted from E12.5 hearts (n=3 for controls and mutants) usinz Trizol and processed for RNA-seq. Reads were mapped to Mm10 reference genome using TopHat2 and Bowtie2. Transcript expression values were determined after transcript normalization with AltAnalyze Results: this analysis revealed a total of 1451 genes significantely (|Fold| > 20% and P<0.05) modulated in Hif1a cKO hearts Overall design: 6 total RNAseq runs with 3 experimental samples and 3 controls samples
