Expression data from spec. transcriptional activity of primary mouse embryonic fibroblasts (MEF) in response to serum.

ABSTRACT: Current methods to analyze gene expression measure steady-state levels of mRNA. In order to specifically analyze mRNA transcription, a technique has been developed that can be applied in-vivo. The technique is referred with the acronym NIAC-NTR (Non Invasive Application and Capture of Newly Transcribed RNA). This method makes use of the cellular pyrimidine salvage pathway and is based on affinity-chromatographic isolation of thiolated mRNA. When combined with data on mRNA steady-state levels, this method is able to assess the relative contributions of mRNA synthesis and degradation/stabilization. It overcomes limitations associated with currently available methods such as mechanistic intervention that disrupts cellular physiology, or the inability to apply the techniques in-vivo. The method has been applied to a model of serum response of cultured primary mouse embryonic fibroblasts. Affymetrix GeneChip microarrays were used to detail regulatory mechanisms of mRNA expression and the relative contributions of RNA synthesis and turnover within distinct pathways, and identification of genes expressed at low abundance at the transcriptional level.

Experiment Overall Design: The gene expression and regulation program at the RNA level early (2h) in response to serum was studied. Total RNA, amplified total RNA and specifically enriched newly transcribed RNA was isolated from serum starved and 2h serum treated MEF cells. This experiment allowed detailed regulatory mechanisms of mRNA expression and the relative contributions of RNA synthesis and turnover within distinct pathways, and identification of genes expressed at low abundance at the transcriptional level of MEF cells early in response to serum.

Transcription profiling of mouse contralateral kidneys in response to ischemia reperfusion injury

Project description:Current methods to analyze gene expression measure steady-state levels of mRNA. In order to specifically analyze mRNA transcription, a technique has been developed that can be applied in-vivo in intact cells and animals. The technique is referred with the acronym NIAC-NTR (Non Invasive Application and Capture of Newly Transcribed RNA). This method makes use of the cellular pyrimidine salvage pathway and is based on affinity-chromatographic isolation of thiolated mRNA. When combined with data on mRNA steady-state levels, this method is able to assess the relative contributions of mRNA synthesis and degradation/stabilization. It overcomes limitations associated with currently available methods such as mechanistic intervention that disrupts cellular physiology, or the inability to apply the techniques in-vivo. The method was applied to study renal ischemia reperfusion injury, demonstrating its applicability for whole organs in-vivo. Affymetrix GeneChip microarrays were used to detail regulatory mechanisms of mRNA expression and the relative contributions of RNA synthesis and turnover within distinct pathways, and identification of genes expressed at low abundance at the transcriptional level. Experiment Overall Design: The gene expression and regulation program at the RNA level of contralateral mouse kidneys of model IRI-mice was studied. Total RNA, amplified total RNA and specifically enriched newly transcribed RNA was isolated from normal untreated mouse kidneys and from contralateral mouse kidneys of IRI-mice. This experiment allowed detailed regulatory mechanisms in-vivo of mRNA expression and the relative contributions of RNA synthesis and turnover within distinct pathways, and identification of genes expressed at low abundance at the transcriptional level of contralateral kidneys early (3h) after ischemia-reperfusion-injury..

Methyl-Spec-seq data for HOXB13

Project description:We developed a novel in-vitro experimental method to characterize the protein-DNA interaction specificity and methylation sensitivity, we called Methyl-Spec-seq. In this data set, mouse HOXB13 (F1-F3) was used as a positive control example to show that Methyl-Spec-seq can determine the relative binding energy for variants with different methylation property, i.e., unmethylated, top hemimethylated, bottom hemimethylated, duplex methylated by either chemical synthesis or enzymatic treatment.

Basonuclin-1 modulates epithelial plasticity and TGF-β1-induced loss of epithelial cell integrity [NIAC-NTR]

Project description:TGF-b1-stimulation induces an epithelial dedifferentiation-process, throughout which epithelial cell sheets disintegrate and gradually switch into fibroblastic-appearing cells (EMT-like transition). The purpose of these profiles was to identify differentially expressed genes that are regulated transcriptionally. Standard microarry-based gene expression profiles measure steady-state RNA but do not provide insight into underlying regulatory principles. NIAC-NTR-based gene expression profiling (Kenzelmann et al., PNAS, 2007) essentially enables the dissection of transcriptionally versus non-transcriptionally regulated genes within respective analysed time-frames. Briefly, NIAC-NTR relies on incorporation of 4sU (thio-uridine) into nascent RNA, which can subsequently be specifically isolated by custom-made columns. Total- and enriched (4sU-labeled) are then further processed for microarray gene expression profiling by standard procedures. This dataset complements previously released data of NIAC-NTR-based gene expression profiling of cells treated with TGF-b1 and 4sU for 2hrs [GSE23833]. The present data and files represent the outcome of NIAC-NTR-based gene expression profiling of cells treated with TGF-b1 for 24hrs and incubation with 4sU for the last 2hrs (22hrs-24hrs of TGF-b1-stimulation).

Expression data from THP1-wt and THP1-NTR+ cells with LSD1 inhibitor (OG86), Nitroreductase NfsB (NTR) prodrug and negative control

Project description:The Nitroreductase NfsB (NTR) prodrug of an LSD1 inhibitor is inactive in wild-type THP1 cells, but the prodrug gets activated in the LSD1 inhibitor by the NTR in NTR-expressing THP1 cells (THP1-NTR+). Cell-type specific inhibition of LSD1 in THP1-NTR+ cells with a NTR prodrug is shown with the expression data of the two cell lines, THP1-wt and THP1-NTR+. Data for the LSD1 inhibitor and a negative control with both cell lines are included.
