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

ABSTRACT: 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

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.

SIK2-dependent Phosphoproteome and Interactome upon Salmonella infection

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.

Expression data from HEK293T cells infected with Shigella or treated with Rapamycin

Project description:Shigella is an intracellular bacterial pathogen known to activate numerous innate immunity and inflammatory signaling pathways. Many of these pathways are also involved in mTOR signaling. We used HEK293T cell cultures and sought to understand how Shigella infection and rapamycin treatment affect the transcriptome and in particular whether there were commonly affected pathways in the two experimental conditions. 8 samples were used - 2 control that were uninfected/untreated -- 1 sample lost due to RNA degradation, 3 infected with Shigella for 4 hours, and 3 treated with Rapamycin (50 ug/mL) for 4 hours. All samples were from independent experiments. We used the program AltAnalyze to perform pairwise comparisons between Uninfected with Infected, and Uninfected with Rapamycin using default parameters.

Neutrophils infected with Leishmania donovani

Project description:In the context of studying visceral leishmaniasis, neutrophils infected with Leishmania donovani have been compared to uninfected neutrophils. Compared time points are 0, 6 and 24 hours post infection. Neutrophils of three human donors have been used. Overall 6 samples for infected neutrophils at time point 6 hours and 6 samples for infected neutrophils at time point 24 hours exist, including three biological samples and two technical samples. Uninfected neutrophils represent 3 samples at time point 0 hours, 3 samples at time point 6 hours and 3 samples at time point 24 hours. Transcriptome of Leishmania donovani culture has been assessed in two replicates.

Gene expression changes in liver upon LCMV Cl13 infection.

Project description:2-3 month old female C57Bl/6J mice were intravenously infected with 2x10^6 focus forming units of lymphocytic choriomeningitis virus strain Clone-13. Whole liver tissue was harvested in duplicated from uninfected control mice, uninfected 123d old mice, and from infected at 2, 8, 30, 60, and 123 days post infection. Three TMT 6-plex runs were carried out to monitor the changes in liver protein abundance during the entire course of infection. The first run included samples from day 2 and day 8 after infection along with the uninfected controls. Similarly, the second run included uninfected controls and samples from day 30 and day 60 after infection. The third run included samples day 123 after infection, the corresponding age matched control that was left uninfected for 123 days and the uninfected controls used in the other two runs. The uninfected controls were included in all the three runs as an internal control to monitor reproducibility between the runs.

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.

Targeted_PRM_Urine_Carnitine_Efficacy_Study_Males_Females

Project description:5-week old male and female Swiss Webster mice were infected with 500,000 Trypanosoma cruzi strain Sylvio X/104 parasites. Urine was collected from uninfected mice pre-infection, from infected and uninfected mice every week for 5 weeks post infection, from infected and uninfected mice 67 (females)/68 (males) days post infection, and from infected and uninfected mice 117 (females)/124 (males) days post infection for acute, mid-chronic, and chronic time-points. Metabolites were extracted with methanol and a targeted PRM LCMS analysis was ran on a Thermo Q Exactive Plus instrument with a Phenomenex Luna Omega Polar C18 column.
