Project description:This series includes arrays from two separate experiments where the gene expression profile of mock treated L929 cells was compared to that of L929 cells that had been infected with wildtype versus nt3A mutant Venezuelan equine encephalitis virus replicon particles (VRP). Total RNA was isolated from all samples at 5 hour post-infection. Keywords: virus infection-induced gene expression changes
Project description:This series includes arrays from two separate experiments where the gene expression profile of mock treated L929 cells was compared to that of L929 cells that had been infected with wildtype versus nt3A mutant Venezuelan equine encephalitis virus replicon particles (VRP). Total RNA was isolated from all samples at 5 hour post-infection. Experiment Overall Design: L929 cells were mock treated or infected at an MOI of 5 with either wildtype or nt3A mutant null-VRP, and total RNA was isolated at 5 hpi using the UltraSpec reagent protocol as described above. The UNC-CH Functional Genomics Core Facility provided Affymetrix sample preparation and hybridization services, hybridizing the samples to Affymetrix Mouse Expression 430A (MOE430A) GeneChip arrays, which include analysis of ~22,600 genes. Affymetrix GeneChip Microarray Suite 5.0 software was used for washing, scanning, and basic analysis, with sample quality assessed by examination of 3â to 5â intensity ratios of certain genes. Expression analysis files created by Microarray Suite were imported into GeneSpring 6.2 (Silicon Genetics) for further gene expression analysis and filtering. Two independent array studies were completed, and gene lists were compiled representing only those genes that were up- or downregulated by greater than 2-fold in replicate analyses.
Project description:We utilized oligonucleotide microarrays to measure cellular mRNA decay rates in mock- or reovirus-infected murine L929 cells to determine if changes in host mRNA expression are a consequence of reovirus-induced alterations in cellular mRNA stability.
Project description:In the present study, we discovered an unexpected interplay between immunometabolism and antiviral immunity. Profiling of human bronchial epithelial BEAS-2B cells was performed using Agilent’s SurePrint G3 human gene expression microarray kit. A single-color design provided two types of comparison: (i) IAV-infected versus mock-infected cells, and (ii) succinate-treated infected cells versus mock-infected cells.
Project description:Zea mays transcriptome profiling of infected seedlings by the Ustilago maydis wildtype and the seedling specific effector mutant demonstrated the variation of gene expression in the mutant and the classes of genes that are absent in the mutant as compared to the wildtype U. maydis SG200 strain. Two dye competitive hybridizations were performed on Agilent Oligo arrays. Comparison were done 1) with mock and infected samples at 6dpi. 2) between the two 6dpi infected samples with wildtype and the secreted effector mutant
Project description:A comparison was made between the THP-1(Human monocytic leukemia cells - TIB-202; ATCC) transcriptional responses of; (i) uninfected versus Coxiella burnetii NMII infected and (ii) uninfected versus Coxiella burnetii NMII infected THP-1 cells transiently treated with bacteriostatic levels (10μg/ml) of chloramphenicol (CAM). Briefly, infections were initiated and cultured in parallel with uninfected cells. At 48 hours post infection (hpi), media containing CAM (10μg/ml) was added to one set of cells (uninfected and infected THP-1 cells) and culturing was continued. The other set of cells were mock treated with normal media. Total RNA was isolated at 72 hpi from all conditions. Microarrays were performed for both condition sets and the results from each of the two microarrays were compared to define the host genes modulated by de novo C. burnetii NMII protein synthesis.
Project description:We treated wildtype and RIP3 knockout L929 with TNF for 8 time points respectively, and used SWATH-MS to quantify dynamic proteomic change of these two cell lines under a serial TNF treatments.
Project description:Microarray expression profilling of mouse primary mixed cortical/hippocampal neurons, primary fibroblasts and L929 cells to compare ISGs signature in disctinct cell types Primary mixed cortical/hippocampal neurons, primary fibroblasts (MEFs) and L929 cells were mock-treated or treated with 5U/mL of IFN-beta and RNA was harvested after 24 hours. For neurons and fibroblast, 2 samples were analyzed for each condition.
Project description:ZIKV alters transcriptional responses of infected cells to avoid immune detection. We have compared the transcriptional responses of ZIKV-infected hBMECs and mock-infected hBMECs. Examination of transcriptional responses of ZIKV-infected hBMECs versus mock-infected hBMECs
Project description:Comparison of gene expression in wildtype and MyD88-/- C57BL/6J mouse macrophages treated with 10 ng/mL LPS for 2 hours versus media treated control macrophages, and, wildtype and MyD88-/- C57BL/6J mouse macrophages treated with live E. coli bacteria (log phase; 1 bact per 1 macrophage) for 2 hours versus media treated control macrophages. Cells from 4 mice of each geneotype were used and each individual provided its own control. Hybridizations of treated and control samples from each mouse were dye swap replicated. Wildtype macrophages treated with LPS vs control (GSM22617-GSM22623,GSM22625), MyD88-/- macrophages treated with LPS vs control (GSM22626-GSM22632), wldtype macrophages treated with E. coli vs control (GSM22633-GSM22640, and MyD88-/- macrophages treated with E. coli vs control (GSM22641-GSM22648).
