Project description:Expression data from NIH-3T3 cells treated with mock, 100 U/ml IFN alpha or 100 U/ml gamma for 1 or 3h on nt-RNA labeled for 30-60 min at different times of interferon treatment; Differential gene expression caused by IFN alpha or gamma was analyzed in newly transcribed RNA (nt-RNA) of NIH-3T3 cells treated for 1 or 3 h. RNA was labeled for 30 to 60 min and separated from total cellular RNA (tc-RNA) following Trizol RNA preparation and thiol-specific biotinylation; We used microarrays to analyze the effects of IFNalpha and gamma treatment in newly transcribed RNA (nt-RNA) Experiment Overall Design: NIH-3T3 cells (5th to 15th passage after thawing) were split 24 h before start of the experiment. When starting the experiment 80% confluency was reached. The experiment was started by applying fresh, prewarmed, CO2-equilibrated medium containing either mock, 100U/ml IFN alpha or 100 U/ml IFN gamma. Labeling was either started simultaneously, 30 or 150 minutes later.
Project description:Differential gene expression caused by 1h and 3h of IFN alpha or gamma treatment was analyzed in total cellular RNA of NIH-3T3 cells compared to mock; We used microarrays to analyze the effects of 1 and 3h of IFNalpha and gamma treatment in total cellular RNA Experiment Overall Design: NIH-3T3 cells ( 5th to 15th passage after thawing) were split from confluent plates 24h before start of the experiment. At the begin of the experiment about 80% confluency was reached. The experiment was started by applying fresh, prewarmed, CO2-equilibrated medium containing either mock, 100U/ml IFN alpha or 100 U/ml IFN gamma. Labeling was either started together with addition of IFN for 60 minutes or for 30 minutes starting 150 minutes after begin of treatment.
Project description:Differential gene expression caused by 1h and 3h of IFN alpha or gamma treatment was analyzed in total cellular RNA of NIH-3T3 cells compared to mock We used microarrays to analyze the effects of 1 and 3h of IFNalpha and gamma treatment in total cellular RNA Keywords: time course in total cellular RNA (tc-RNA)
Project description:NIH-3T3 cells were pretreated for 15 min with either DMSO (mock) or cycloheximide followed by addition of either mock, 100 U/ml IFNalpha or 100 U/ml IFNgamma for 1h. During the last 30 min, 500 µM 4-thiouridine was added to cell culture medium. Total cellular RNA was isolated using Trizol reagent and nascent RNA was purified as described (Dölken et al. RNA 2008) . Three replicates of nascent RNA were analyzed by Affymetrix Mouse Gene ST 1.0 arrays Primary (translation independent) from secondary (translation dependent) IFN-mediated differential gene expression were studied in NIH-3T3 fibroblasts by studying studying differential gene expression in presence and absence of Cycloheximide (CHX). In addition, the effect of 75 min CHX during the last 30 min of treatment was studied in nascent RNA.

Project description:Analysis of Bone Marrow derived macrophages (BMDMs) incubated in presence of Lipopolysaccharide (LPS) (10ng/ml) + Interferon -gamma (IFN-g) (20ng/ml) for 8 h vs Mock treated controls
Project description:Data from tc-, nt- and p-RNA as well as 1 and 2h of actinomycin-D treatment (5µg/ml) of NIH-3T3 cells used to determine half-lives. RNA was labeled for 15, 30 or 60 minutes with 4-thiouridine. After preparation of tc-RNA, thiol-labeled RNA was biotinylated using biot-HPDP and subsequently tc-RNA was separated into nt- and p-RNA using streptavidin coated magnetic beads. All three fractions were used for microarray analysis. For actinomycin-D experiments only tc-RNA was used prepared from cell before and 1 an 2h after addition of act-D. We used microarrays to analyze the effects of 1 and 3h of IFNalpha and gamma treatment in total cellular RNA Keywords: determination of RNA half-lives in NIH-3T3
Project description:Proteomics of carboxylated polystyrene bead (1.0 um) phagosomes from murine bone marrow-derived macrophages. cells were either resting or treated with 100 U/ml IFN-γ (PeproTech) and 100 ng/ml LPS (Sigma) for 24 h, 20 ng/ml Interleukin-4 (IL4) (BD Pharmingen) for 48 h, 20 ng/ml Interleukin-13 (IL13), 10 ng/ml Interleukin-10 (IL10)for 48 h or Reprogrammed (IL4 was incubated with BMDMs for 24 h, and the medium was replaced with fresh medium containing IFN-γ/LPS to incubate for another 24 h). Phagosomes were isolated after 30 min bead inoculation.
