Transcriptomic profiling of HeLa cells infected with Shigella flexneri

Project description:We evaluated the transcriptome changes induced by infection of Hela 229 cells with Shigella flexneri. The sample set consists of a control (mock), total population of infected sample and infected sample sorted into Shigella positive and Shigella negative population.

HeLa Cells infected with Shigella in the presence/absence of Staurosporin

Project description:Question Addressed: What is the host response (specifically apoptosis pathways) to Shigella infection and what is the contribution of MxiE to the host response? The arrays are apoptosis Exon hit arrays, thus splice variation can be determined. Array data from HeLa cells that remained Uninfected or were infected with wildtype S. flexneri serotype 2a strain 2457T or an isogenic mixE mutant. These groupings are further divided such that Uninfected or Infected cells remained untreated or were treated with the apopotosis inducer staurosporine (STS). The design of the experiment was a time course and samples were harvested at the indicated time points (hr). All hybridizations were conducted against a common reference sample that was made from pooled samples of normal uninfected healthy HeLa cells. Infection: HeLa cells were infected with wt Shigella (wt), mxiE mutant (mixE) or were left uninfected (uninfected) Compound Based Treatment: Cultures were treated with Staurosporin (STS) or were left untreated (untreated) Infection time: Cells were harvested at the indicated time after treatment

Identification of IFNg-regulated, IRF1-dependent genes in Shigella flexneri-infected mouse embryonic fibroblasts (MEFs)

Project description:This experiment was designed to identify IFNg-regulated, IRF1-dependent genes during infection with the intracellular pathogen Shigella flexneri. WT and Irf1-/- MEFs were stimulated for 18 hours with IFNg or left unstimulated; all of the cells were subsequently infected for 6 hours with S. flexneri prior to harvest of total RNA.

Human Sumoylome (SUMO-2) upon bacterial infection

Project description:Given the role of SUMOylation in pathogenic infection, we wanted to evaluate the changes to the host SUMO-2 subproteome during Shigella infection. HeLa cells overexpressing TAP-SUMO-2 or TAP-empty were used in conjunction with SILAC (Stable Isotope Labeling of Amino acids in Culture) (Golebiowski et al, 2009, 2010). Cells were grown in Dulbecco’s modified Eagle’s medium except that L-arginine and L-lysine were replaced with stable isotope (SILAC) forms depending on the treatment. Medium was supplemented with 10% dialyzed fetal calf serum. SILAC experiment compared TAP-containing cells (Lys0 and Arg0) with invasive Shigella flexneri (M90T) infected TAP-SUMO-2-containing cells (4,4,5,5-D4-lysine, Lys4, and 13C6- arginine, Arg6) and TAP-SUMO-2-containing cells infected with (mxiD) non-invasive strain of Shigella (13C6 15N2-lysine, Lys8, and 13C6 15N4 -arginine, Arg10).

Detection of Q-modification in RNAs from S. pombe and S. flexneri via reverse transcription using RT-KTq I614Y (Q-MaP-Seq)

Project description:In most eukaryotes and bacteria, queuosine (Q) replaces the guanosine at the wobble position of tRNAs harboring a GUN anticodon. To faithfully detect Q-modification in RNAs from Schizosaccharomyces pombe and Shigella flexneri, Q-MaP-Seq was established and applied to tRNAs from S. pombe WT (AEP1) cells and Shigella flexneri WT cells and tgt∆ cells. Q-modification of in vitro-transcribed RNAs and RNAs isolated from S. pombe and S. flexneri followed by reverse transcription using the RT-active DNA polymerase variant RT-KTq I614Y and sequencing of unmodified compared to modified RNAs allowed identification of Q-sites within tRNAs.
