Project description:Escherichia coli release Extracellular Vesicles (EVs) which carry diverse molecular cargo. Pathogenic E.coli EVs contain virulence factors which assist during infection in the host in different mechanisms.The RNA cargo of E.coli EVs has not been assessed in their effect in the host. We used microarray data to asses and compare the global response of bladder cells to EV-RNA from pathogenic E.coli (Uropathogenic UPEC 536) and non-pathogenic E. coli (probiotic Nissle 1917)
Project description:We measured the mRNA abundance in E.coli using RNAseq to calculate mRNA lifetimes. The data is used in support of a larger paper on the proteome and transcriptome of E.coli.
Project description:To determine the total mRNA polyadenylated in E.coli, we transexpressed mammalian nuclear poly(a) binding protein in E.coli through plasmid and chromosomal integration. RNA Seq analysis revealed general upregulation of around 600 genes commonly in between chrosomal MG PABP and plasmid PABP. 32% of the commonly upregulated genes fall into stress response mRNAs.
Project description:We performed tRNAome sequencing to assess the tRNA changes of E.coli under oxidative stress. We found that the global translation inhibition is caused by global down-regulation of almost all tRNA species under oxidative stress. The translation elongation speed is resumed after the cells are fully adapted to the oxidative environment.
