Enterococcus faecalis nucleotide profiles following mupirocin or decoyinine

ABSTRACT: Triplicate samples of E. faecalis OG1RF will be grown in FMC-AUG to OD600 = 0.25. The cultures will be split and exposed to DMSO, mupirocin (0.01mg/mL) or decoyinine (0.1mg/mL) for 15 minutes. 6E9 cells will be harvested by fast filtration, scraped off of membrane into ice-cold PBS, and pelleted by centrifugation, and stored at -80C until shipment.

Enterococcus faecalis nucleotide profiles - pilot

Project description:E. faecalis OG1RF and rel/relQ will be grown in FMC-AUG to OD600 = 0.25. 3E10 cells will be harvested by fast filtration, scraped off of membrane into ice-cold PBS, and pelleted by centrifugation. This process will be repeated with OG1RF only to harvest 3E9 and 3E8 cells. A second OG1RF sample of 3E10 cells will be scraped into formic acid; only acid-soluble extract willl be sent for this sample.

Streptococcus mutans organic acids/amino acid profiles, effect of oxidative stress; pilot

Project description:S. mutans UA159 and ΔspxA1 will be grown in BHI to OD600 = 0.4. Each culture will be split in to 4 samples. For the first sample, 3E10 cells will immediately be harvested by fast filtration, scraped off of membrane into ice-cold PBS, and pelleted by centrifugation. The remaining three samples will be treated with H2O2 to 0.5 mM, and the harvesting process repeated after 15, 30 and 60 minutes.

Shewanella oneidensis outer membrane and outer membrane vesicles

Project description:This project compares the outer membrane proteome to the proteome of outer membrane vesicles of the bacterium Shewanella onedensis. S. oneidensis outer membrane was purified via the sarkosyl method described in (Brown, 2010). A 50 mL overnight culture of cells were harvested by centrifugation at 10,000× g for 10 min. cell pellet suspended in 20 mL of 20 mM ice-cold sodium phosphate (pH 7.5) and passed four times through a French Press (12000 lb/in2). The lysate was centrifuged at 5,000× g for 30 min to remove unbroken cells. The remaining supernatant was centrifuged at 45,000 × g for 1 h to pellet membranes. Crude membranes were suspended in 20 mL 0.5% Sarkosyl in 20 mM sodium phosphate and shaken horizontally at 200 rpm for 30 min at room temperature. The crude membrane sample was centrifuged at 45,000 × g for 1 h to pellet the OM. The pellet of OM was washed in ice-cold sodium phosphate and recentrifuged. The cells were pelleted by centrifugation at 5000 x g for 20 min at 4°C, and the supernatant was filtered through 0.45 μm pore size filters to remove remaining bacterial cells. Vesicles were obtained by centrifugation at 38,400 x g for 1 h at 4°C in an Avanti J-20XP centrifuge (Beckman Coulter, Inc). Pelleted vesicles were resuspended in 25 ml of 50 mM HEPES (pH 6.8) and filtered through 0.45 μm pore size filters. Vesicles were again pelleted as described above and finally resuspended in 50 mM HEPES, pH 6.8. Extracellular DNA, flagella, and pili can all be co-purified. Protocol was adapted from (Perez-Cruz, 2013).

Effect of nitroprusside on the proteomic expression of Desulfovibrio vulgaris Hildenborough

Project description:In this study, the effect of nitroprusside on protein expression of the model sulfate reducing bacterial isolate (Desulfovibrio vulgaris Hildenborough) was investigated. Three different experiments were done with different exposure time to nitroprusside (30 min, 1 hour, and 3 hours). In each experiment, the culture was grown in quadruplet of serum bottles containing 40 ml complex medium (Postgate medium B) under anaerobic condition at 30oC. At mid-log growth phase, each of the quadruplet culture was divided into two (20 ml each) and nitroprusside (0.25 mM) was added to one of each bottle while the other bottles were used as controls. After 30 min, 1 hour, and 3 hours of exposure to nitroprusside, the culture (1 ml) was pelleted and used for proteomic analysis.

RNAseq Analysis CD4+ T cells response to isoalloLCA treatment in vitro

Project description:We examine the transcription response of murine CD4+ T cell cultured under Th0 condition (anti-CD3; anti-CD28; IL-2), treated with DMSO, isoalloLCA (20 uM) for 48 hrs, or in the presence of TGFbeta (0.25 ng/mL). We compare the differential genes regulated by isoalloLCA and TGFbeta.

Mefloquine treatment of NG108 rat neuronal cells

Project description:This data series describes expression data for eight paired, control and treated cell cultures obtained on independent occasions. NG108 rat neuronal cell cultures were exposed to either 0.25% DMSO (control) or 4400 ng/ml mefloquine (treated) for two hours. Validation: Modulation of the following transcripts by mefloquine was confirmed by semi-quantitative RT-PCR: U30186, X63594cds_g_at, X63594cds_at, X17163cds_s_at, rc_AI175959 and rc_AA945867 (unpaired, unequal variance, one tailed t-test, p < 0.05).

Bone marrow-derived mast cells +- IL-33 48h

Project description:Mast cells are tissue resident granulocytes which are most abundant at the interface between tissues and the external environment, such as around blood vessels, in the skin or mucosal surfaces in the lungs and gut. Pathologically they are involved in allergic reactions and anaphylaxis, however they may also play protective roles in responses to some infections, particularly to pathogenic helminths. Mast cells also express high levels of the IL-33 receptor, which like TLRs, activates Myd88 dependent signalling pathways to drive de novo cytokine production in mast cells.IL-33 is a member of the IL-1 family known to stimulate a number of immune cell types including mast cells. IL-33 is a strong activator of de novo cytokine production in mast cells without inducing degranulation, although it has also been shown to synergise with other signals to promote degranulation. Bone Marrow-Derived Mast cells (BMMCs) were cultured as described previously [27]. Briefly, bone marrow was flushed in PBS and the cells pelleted by centrifugation. Cells were cultured at 1 million cells per ml in RPMI 1640 supplemented with 10% FBS (Biosera/Labtech), 5 mM l‐Glutamine (GIBCO Life Technologies), 100 U/ml Penicillin (GIBCO Life Technologies), 100 μg/ml Streptomycin (GIBCO Life Technologies), 25 mM HEPES (Lonza), 1 mM sodium pyruvate (Lonza), 1X nonessential amino acids (Lonza), 50 μM 2‐mercaptoethanol and 30 ng/ml IL‐3 (PeproTech). Cells were passaged twice per week and used between passage 12 and 16. 4 independent BMMC cultures were either stimulated with 10 ng/ml IL-33 for 48 hours or left unstimulated, followed by single shot LC-MS analysis.

Gene expression profiling of Mycobacterium tuberculosis H37Rv in response to compound CDRI-5g

Project description:Gene expression profiling of Mycobacterium tuberculosis H37Rv in response to compound CDRI-5g (Saquib, M. et al. Eur. J. Med. Chem. 46 (2011) 2217-2223) was studied by administration of compound at 10 µg/ml in broth culture. RNA was extracted at two time points 12 h and 24 h of growth from replicating phase and compound added culture. Replicating phase culture was incubated for the same time and used as a control. Experiment was repeated three times and for each time points triplicate culture was pelleted to isolate total RNA using Qiagen RNA isolation kit.

E. coli MG1655 pJV300 stationary phase

Project description:Over-night cultures grown from three single colonies were diluted 1:100 in LB and grown with shaking at 37 °C for 6h. Bacteria were pelleted by centrifugation and fast-freezed in the presence of 0.9 mg/ml lysosyme in TE. Frozen cells were thawed and re-frozen twice in 37 °C and liquid nitrogen, respectively. Total RNA was extracted using TRI-reagent and used for construction of RNA-seq libraries according to the RNAtag-seq method. Libraries were paired-end sequenced using Illumina NextSeq 500 platform.
