Description
Global Run-On has been performed on WT or KD for RECQL5 cells after release from DRB. When RECQL5 is knocked-down the transcriptional wave front is more advanced, suggesting that transcription is faster. Overall design: Constitutive knock-down cell lines expressing or not endogenous levels of shRNA resistant RECQL5 under a Doxycycline inducible promoter were treated with high doses of DRB to block transcription. Upon release into fresh medium we were able to follow how much and how fast the RNA Pol II progresses through genes by mapping nascent RNA by Run-On. The experiment was performed in two cell line clones.

Description
In addition to KIT and PDGFRA mutations, sequential accumulation of other genetic events is involved in the development and progression of gastrointestinal stromal tumors (GISTs). Until recently, the significance of these other alterations has not been thoroughly investigated. The combination of gene expression profiling and high-resolution genomic copy number analysis offers a detailed molecular portrait of GISTs, providing an essential comprehensive knowledge necessary to guide the discovery of novel target genes involved in tumor development and progression.

Description
The transcription-related DNA damage response was analyzed on a genome-wide scale with great spatial and temporal resolution. Upon UV irradiation, a slowdown of transcript elongation and restriction of gene activity to the promoter-proximal ~25 kilobases is observed. This is associated with a shift from expression of long mRNAs to shorter isoforms, incorporating alternative last exons (ALEs) that are more proximal to the transcription start site. Notably, this includes a shift from a protein-coding ASCC3 mRNA to a shorter transcript isoform of which the RNA, rather than an encoded protein, is critical for the eventual recovery of transcription. The protein-coding ASCC3 isoform counteracts the function of the non-coding isoform, indicating crosstalk between them. Thus, the ASCC3 gene expresses both coding and noncoding transcript isoforms with opposite effects on transcription recovery after UV-induced DNA damage

Overall design: Cells were treated with DRB (100 µM, 3.5 hrs), followed by UVC irradiation (15 J/m2) or left untreated. Cells were washed with PBS to remove DRB immediately after UV irradiation and incubated for 10, 25 or 40 minutes, followed by cell lysis and nuclei isolation. Nuclei were processed for GRO-Seq.

Description
Celiac disease (CeD) is an intestinal immune-mediated disorder caused by gluten ingestion in genetically predisposed subjects. CeD is characterized by villous atrophy, altered intestinal permeability, crypt hyperplasia and innate and adaptive immune response. This study aimed to develop and validate the use of intestinal organoids from celiac patients to study CeD. A repository of organoids from duodenum of non-celiac and celiac patients was generated and characterized accordingly to standard procedures. RNA-seq analysis was employed to study the global gene expression program of CeD (n=3) and non-CeD (n=3) organoids sets. While the three celiac derived organoids shared similar transcriptional signatures the NC samples set appeared more heterogeneous. We found 486 genes differentially expressed between the two groups. Of them, 299 genes were downregulated (FC<2; FDR<0.05) and 187 were upregulated in CeD (FC >2; FDR<0.05). We observed CeD organoids had significantly altered expression of genes associated with barrier function, innate immunity, and stem cell function. Overall design: mRNA profiles of 3 non-celiac healthy controls and 3 celiac organoids derived from duodenal biopsies.

Description
Aminaphtone, a drug used in the treatment of chronic venous insufficiency (CVI), showed a remarkable role in the modulation of several vasoactive factors, like endothelin-1 and adhesion molecules. We analysed in vitro the effects of Aminaphtone on whole-genome gene expression. ECV304 endothelial cells were stimulated with IL-1 100 U/ml in the presence or absence of Aminaphtone 6 g/ml. Gene expression profiles were compared at 1, 3, and 6 h after stimulation by microarray.

Gene expression profiling reveals novel protective effects of Aminaphtone on ECV304 endothelial cells.
