Project description:RNA from in vitro grown Salmonella typhimurium is compared with RNA extracted from Salmonella typhimurium from infected chick caecums using a common DNA reference. Keywords: Disease state analysis, infected versus uninfected, common reference
Project description:RNA from in vitro grown Salmonella typhimurium is compared with RNA extracted from Salmonella typhimurium from infected chick caecums using a common DNA reference. Keywords: Disease state analysis, infected versus uninfected, common reference Five replicates from infected chick caecal contents compared to a common reference. Three replicates from in vitro grown Salmonella compared to a common reference. The common reference was genomic DNA and always occupies the Cy3 channel (channel 2).
Project description:HeLa cells transfected with non-targeting control- and anti-SIK2 siRNA were left uninfected or infected with Salmonella and lysed 30 min pi. Following tryptic-digest peptides were labeled using TMT-pro 16-plex and phosphopeptides enriched. The endogenously tagged SIK2-HA IP workflow. Hela wild type or endogenous SIK2-HA-tagged HeLa cells were left uninfected or infected with Salmonella and lysed 1 h post-infection, followed by HA-IP, Tryptic digest, TMT-labeling and LC-MS/MS analysis.
Project description:We have sequenced miRNA libraries from human embryonic, neural and foetal mesenchymal stem cells. We report that the majority of miRNA genes encode mature isomers that vary in size by one or more bases at the 3’ and/or 5’ end of the miRNA. Northern blotting for individual miRNAs showed that the proportions of isomiRs expressed by a single miRNA gene often differ between cell and tissue types. IsomiRs were readily co-immunoprecipitated with Argonaute proteins in vivo and were active in luciferase assays, indicating that they are functional. Bioinformatics analysis predicts substantial differences in targeting between miRNAs with minor 5’ differences and in support of this we report that a 5’ isomiR-9-1 gained the ability to inhibit the expression of DNMT3B and NCAM2 but lost the ability to inhibit CDH1 in vitro. This result was confirmed by the use of isomiR-specific sponges. Our analysis of the miRGator database indicates that a small percentage of human miRNA genes express isomiRs as the dominant transcript in certain cell types and analysis of miRBase shows that 5’ isomiRs have replaced canonical miRNAs many times during evolution. This strongly indicates that isomiRs are of functional importance and have contributed to the evolution of miRNA genes
Project description:Caco-2 cells grown on transwells were infected with Japanese encephalitis virus (JEV) and total RNA was isolated from cells at the time when trans-epithelial electrical resistance was reduced by about 50% of uninfected cells
Project description:The Affymetrix bovine global microarray was used to examine the transcriptional response of Holstein-derived macrophages and dendritic cells infected with heat-inactivated Salmonella (n=6), live Salmonella (n=6) and uninfected controls (n=6) during early infection (2 hours)
Project description:Gene expression profiling of immortalized human mesenchymal stem cells with hTERT/E6/E7 transfected MSCs. hTERT may change gene expression in MSCs. Goal was to determine the gene expressions of immortalized MSCs.
Project description:Human fibroblasts were infected with GFP-expressing Salmonella enterica serovar Typmimurium and further separated by Fluorescence Activated Cell Sorting. RNA from infected and uninfected cells sub-populations were used for genome-wide expression studies
