RNAseq from Membrane vesicles of Pseudomonas aeruginosa

ABSTRACT: Transcriptomic from membrane vesicles retreived at different optical densities secreted by Pseudomonas aeruginosa. Moreover, we performed an RNAseq from cells retrieved at optical density OD=1.6 (exponential phase), to compare with the RNA internalized on vesicles.

In situ imaging of the bacterial flagellar motor reveals stable inner- and outer-membrane associated sub-complexes during motor assembly and disassembly

Project description:Using electron cryo-tomography (ECT), we show that, in three bacterial species, the flagellar motor disassembly process results in stable outer-membrane-embedded sub-complexes. These sub-complexes consist of the periplasmic embellished P- and L-rings, and bend the membrane inward while it remains apparently sealed. Our experiments show that these sub-complexes are more enriched in the cells at high optical-density (OD 600 ). In order to identify candidates for the protein(s) that may play a role in sealing the outer membrane we performed mass spectrometry experiments on membrane vesicles isolated from Shewanella oneidensis MR-1 cells grown to two different optical densities (OD 600 sample 1 ~ 5, OD 600 sample 2 ~ 0.6). Based on certain criteria, we identified few candidate proteins that are overexpressed in cells grown to high OD 600 and that might be involved in sealing the membrane after flagellar motor disassembly.

Cell-density resolved comparative analysis of D. shibae wild-type vs. delta-luxI1 overexpressing luxI1 in trans

Project description:D. shibae delta-luxI1 overexpressing the luxI1 gene in trans was compared to the wild-type in order to identify quorum sensing controlled traits in this organism. Samples were taken at different optical densities in the exponential phase and in the stationary phase. Samples from Dinoroseobacter shibae DFL 12 wild-type and delta-luxI1pDP1 are compared during exponential (OD600 0.1, 0.2, 0.4, 0.6, 0.8) and stationary phase (6h post maximum OD600), two biological replicates

Cell-density resolved comparative analysis of D. shibae wild-type vs. delta-luxI1

Project description:A quorum sensing null mutant was compared with D. shibae wild-type in order to identify quorum sensing controlled traits in this organism. Samples were taken at different optical densities in the exponential phase and in the stationary phase in order to clarify if quorum sensing regulation is dependent on cell-densitiy Samples from Dinoroseobacter shibae DFL 12 wild-type and delta-luxI1 (Dshi_0312) are compared during exponential (OD600 0.1, 0.2, 0.4, 0.6, 0.8) and stationary phase (6h post maximum OD600), two biological replicates

CELL-EXO_01

Project description:In this study, we address mRNA composition of hepatocyte-like derived extracellular vesicles (EVs), using as cellular model the mouse liver derived cell line MLP29, and primary cell culture of rat hepatocyte (RH) obtained by in vivo liver perfusion. The study shows qualitative characterization of RNA, identification of transcripts and its functional characterization through gene expression array technique. To reach a deeper nowledge in the biology of EVs, we perform RNase protection assay, density gradients matching RNA with typical exosomal protein markers, and capture assays to probe that mRNA was internalized. Aim of the project: To identify transcripts present in extracellular vesicles secreted by Rat hepatocytes primary cell culture and to identify extracellular vesicles secreted by mouse hepatocyte cell line MLP29, and in this case, compare the enrichment of transcripts respect to the cell, to know if the composition in the extracellular vesicles is similar to the cell, or if their composition is not directly determined by the abundance of transcripts in the cell.

Stress response regulators identified through genome-wide transcriptome analysis of the stringent response in Rhizobium etli

Project description:The impact on gene expression by the alarmone (p)ppGpp during growth and non-growth was determined by comparing the transcriptome of R. etli CFN42 wild type and rel mutant. This allowed us to better understand the pleiotropic stress phenotype of the rel mutant as well as identifying specific (p)ppGpp-dependent stress regulators. In order to study expression, R. etli CFN42 wild type and rel mutant was grown at 30˚C in acid minimal salts medium supplied with 10 mM NH4Cl and 10 mM succinate while monitoring the optical density (OD) of the culture. Samples were taken at OD600 = 0.3, 0.7 and 6 hours after reaching the maximum OD, representing early/late exponential and stationary phase, respectively.

Transcriptome analysis of Rhizobium etli’s free-living and symbiotic non-growing state.

Project description:Gene expression during stationary phase and symbiosis of R. etli CFN42 was compared to that of exponentially growing cells. This allowed us to better understand how R. etli adapts to a non-growing lifestyle, both the free-living and symbiotic state, as well as to determine to what extent this adaptation is similar in both states. R. etli CFN42 was grown at 30˚C in AMS medium supplied with 10 mM NH4Cl and 10 mM succinate while monitoring the optical density (OD) of the culture. Free-living samples were taken at OD600 = 0.3 and 6 hours after reaching the maximum OD, representing early exponential and stationary phase respectively. Bacteroid samples were obtained from nodules 3 weeks after inoculation of Common bean plants (Phaseolus vulgaris cv Limburgse vroege).

Halobacterium salinarum NRC-1 growth curve

Project description:Halobacterium salinarum NRC-1 was grown in CM media, at 37oC in a waterbath with agitation of 125 rpm under constant light. Analysis of transcriptional changes during growth, in addition to mapping of transcriptome structure under the same conditions, provided interesting insights about regulatory logic within prokaryotic coding regions. Samples were collected at different cell densities, from OD ~0.2 to OD ~5.0. 2 biological replicates were conducted. For each sample, a dye-swap experiment was performed.
