Affymetrix Human Gene 1.0 ST Array (hugene10st)
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.
Publication Title
Gene expression profiling reveals novel protective effects of Aminaphtone on ECV304 endothelial cells.

Description
Mouse embryonic fibroblasts deficient for p53 and expressing mutant RasV12 were infected with lentiviral constructs carrying short hairpin RNAs targeting ARF or a scrambled control. Four days post infection, cells were harvested for microarray analysis.
Publication Title

Description
Gene expression was studied in whole kidneys in a 2 x 2 design. SBH/y were contrasted with SBN/y under basal conditions and after salt loading. Thus, four groups were studied altogether. Five rats were used in each group. Altogether, 20 animals were used, and each animal was studied separately. Gene expression was done in kidney. Differential gene expression was measured 4 weeks after initiation of salt loading. At that time point hypertension invariably evolves fully in SBH/y but not in SBN/y.<br></br><br></br>Affymetrix CHP files are available on request from arrayexpress@ebi.ac.uk

Illumina Genome Analyzer IIx
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.
Publication Title
RECQL5 controls transcript elongation and suppresses genome instability associated with transcription stress.

- Affymetrix Rat Genome 230 2.0 Array (rat2302)
Description
This study was designed to investigate gene expression in kidneys of adult female Sabra rats (SBH/y and SBN/y rat strains) with two indwelling kidneys or after uni-ninephrectomy, seeking those genes that are differentially expressed between the two strains, and between animals with one or two kidneys. SBH/y after uninephrectomy develop proteinuria to a much greater extent than SBN/y. The study was performed as part of an overall effort to detect the genes that are associated with the pathophysiology of proteinuria.
Publication Title
Geno-transcriptomic dissection of proteinuria in the uninephrectomized rat uncovers a molecular complexity with sexual dimorphism.

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.
Publication Title
Human gut derived-organoids provide model to study gluten response and effects of microbiota-derived molecules in celiac disease.

- Illumina HumanHT-12 V4.0 expression beadchip
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
