Project description:To have a global picture of the miRNAs regulated upon treatement with secretome of Salmonella infected cells, we assessed small RNA changes, by RNA-sequencing, of HeLa cells treated with sectretome of Salmonella infected cells or mock-treated cells

Project description:It is becoming increasingly clear that cells infected with pathogens can signal to bystander cells. Infected cells have the ability to alert and instruct bystander cells to mount pro-inflammatory cytokine response, thus contributing to clearing infections. Here we analyse secretome of HeLa cells infected with Salmonella enterica serovar Typhimurium strain SL1344. Cells were infected with a MOI of 100 for 14 hours. Secretome from mock- and Salmonella-infected cells was collected for mass-spectrometry analysis.

Project description:We identified miRNAs differentially regulated upon Salmonella infection by comparative deep-sequencing analysis of cDNA libraries prepared from the small RNA population (10–29 nt) of HeLa cells infected with Salmonella (20 hpi) and mock-treated cells. Considering that at a MOI of 25 Salmonella is internalized in only 10-15% of the HeLa cells, we separated the fraction of cells which had internalized Salmonella (Salmonella+) from the bystander fraction (Salmonella-) by fluorescence-activated cell sorting (FACS), and extended the analysis of miRNA changes to these samples. Interestingly, we observed that Salmonella infection induces a significant decrease in the expression of all the detected members of the miR-15 family

Project description:We identified miRNAs differentially regulated upon Salmonella infection by comparative deep-sequencing analysis of cDNA libraries prepared from the small RNA population (10M-bM-^@M-^S29 nt) of HeLa cells infected with Salmonella (20 hpi) and mock-treated cells.

Interestingly, we observed that Salmonella infection induces a significant decrease in the expression of all the detected members of the miR-15 family miRNA profiles of HeLa cells infected with Salmonella Typhimurium were generated by deep sequencing, using Illumina HiSeq2000.

Project description:In a time course study, we characterized global gene expression profile of B. melitensis-infected epithelium-like cells at the onset of infection. B. melitensis-infected HeLa cells exhibited a down-regulated expression profile at 4 h (48 up- and 109 down-regulated genes) that transitioned to an activated transcriptional profile at 12 h post-infection (733 up- and 224 down-regulated genes). The analysis of the results indicates that infected cells undergo an adaptation period during the first 4 h p.i. that is overcome by 12 h p.i., permitting Brucella to replicate intracellularly while minimally affecting host physiological processes. Specific genes and biological processes identified in this study will further help elucidate how both host and Brucella interact during the early infectious process to the eventual benefit of the pathogen and to the detriment of the naM-CM-/ve host. Keywords: Time course study of gene expression profile of Brucella melitensis-infected HeLa cells We generated 4 different samples: A) RNA isolated from Brucella melitensis-infected HeLa cells at 4 h p.i.; B) RNA isolated from non-infected HeLa cells at 4 h p.i. of the A samples; C) RNA isolated from Brucella melitensis-infected HeLa cells at 12 h p.i., and D) RNA isolated from non-infected HeLa cells at 12 h p.i. of the D samples. The B. melitensis-infected HeLa cells gene expression was compared with gene expression from non-infected HeLa cells treated similarly. There are four biological replicates of each sample and time point (n=16). ORFs were single spotted on each microarray. Each replicate was normalized against labeled universal human reference RNA.

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.

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
