Multi-component Toxicological Study on Rare Earth Upconversion Nanoparticles

ABSTRACT: UCNPs@PEG was divided into three groups, 0.0 mg/mL, 0.25 mg/mL, 1.0 mg/mL, and each concentration was repeated for three groups. After co-culture with AML12 cells for 24h, the medium was removed by pipette gun, and sterilized PBS was added for washing 3 times. 300μ L RIPA cell lysate was added to the culture dish. The lysed cells were scraped off with sterile cell scraper, and the lysed cell solution was sucked into the cryopreservation tube.(TandemMassTags) Labeled protein for proteomic study. First extract the total protein in cells, then do concentration determination and SDS-PAGE detection, then use TMT labeled protein after protease hydrolysis, label samples after uniform mixing chromatography separation, and then LC-MS/MS analysis. Chromatographic reaction conditions: A phase H2O-FA (99.9: 0.1, v/v), Phase B ACN-H2O-FA (80: 19.9: 0.1, v/v/v), mass resolution 60000, scan charge-to-mass ratio range 350-1500, collision energy 32, resolution 45000, automatic gain control 2e5. Functional annotation analysis of identified proteins was carried out using common protein databases. Differential proteins were screened and GO, KEGG and interaction analysis were carried out respectively. Cluster thermomap and Veen analysis were used to analyze differential data.

Transcriptomic profiling of a heme-deficient mutant (hemA) of Escherichia coli after addition of CORM-3 and inactive CORM-3 (iCORM-3).

Project description:Wild type and hemA strains of Escherichia coli MG1655 were grown under anaerobiosis in batch culture in custom-made, stirred (200 rpm) 250 ml mini-fermenter vessels at 37 °C during continuous sparging with 100 % nitrogen gas. Cells were grown in defined medium (pH 7.0) containing 0.5 % glucose as the sole and limiting source of energy and carbon. The medium was supplemented with 0.1 % casamino acids and 5 % LB to support the growth of the hemA mutant. For maintenance of the hemA mutation, 50 mg/ml kanamycin were added to cultures of the heme-deficient mutant only. CORM-3 (final concentration of 100 uM) was added to wild type and mutant cultures at an OD600 of 0.2. iCORM-3 (final concentration of 100 uM) was added to only mutant cultures at an OD600 of 0.2. Samples were taken immediately prior to the addition of CORM-3 or iCORM-3 and at consecutive time-points thereafter (10, 20, 40, 60 and 120 min) for microarray analysis. Cells were harvested directly into phenol:ethanol to stabilise RNA and total RNA was purified using Qiagen’s RNeasy Mini Kit, according to the manufacturer's instructions.

Transcriptional profiling of Escherichia coli during a transition from zinc starvation to surfeit

Project description:Escherichia coli strain MG1655 was grown in a Zn-depleted custom-built chemostat. Culture volume (120 ml), temperature (37 oC) and stirring speed (440 rpm) were maintained. Steady state values for pH and OD600 were 6.9 and 0.6, respectively. Chemostats were grown for 50 h to allow five culture volumes to pass through the vessel and allow an apparent (pseudo-)steady state to be reached. At this point, ZnSO4.7H2O in water was added to a final concentration of 0.2 M in the chemostat. A 10 ml sample of culture was taken using a polypropylene pipette tip immediately prior to Zn addition and 2.5, 7, 10 and 30 min after addition. Samples were harvested into RNAprotect and total RNA was purified using Qiagen’s RNeasy Mini kit (using the supplier’s protocol) prior to use in microarray analysis. A control experiment was also carried out in which water was added. Biological experiments were carried out twice (i.e. control (water added) and experiment (ZnSO4 added) chemostats were grown separately twice), and a dye swap performed for each experiment, providing at least two technical repeats for each of the two biological repeats at all five time points. Slides were analysed so that time points “with Zn” were compared to the same time point “without Zn” (e.g. 30 min after Zn was added was compared to 30 min after water being added).

Monobromobimane labelling in early- and late-passage primary human mesemchymal stem cells subjected to 2 hour heat shock

Project description:Monobromobimane (mBBr) labelling: mBBr labelling was carried out either immediately prior to 42°C, two hour heat shock, or immediately following heat shock. Medium was removed from culture flasks and cells were washed using PBS. Cells were then labelled by incubation at 37°C with 6 mL of 400 µM mBBr (Sigma-Aldrich, #B4380) for 10 minutes. Following labeling, 6 ml of 2 mM L-glutathione reduced (GSH, SigmaAldrich, #G4251) in PBS was added to quench the mBBr reaction. The quenched mBBr solution was removed and cells were washed with PBS. Mass spectrometry (MS) sample preparation, analysis and data processing: Six 1.6 mm steel beads (Next Advance Inc.) were added to the cell pellet tube with 30 µL SL-DOC (1.1% (w/w) sodium dodecyl sulfate (Sigma), 0.3% (w/w) sodium deoxycholate (Sigma), 25 mM ammonium bicarbonate (AB, Fluka), in de-ionised (DI) water containing 0.1% (v/v) protease inhibitor cocktail (Sigma), and 0.1% (v/v) phosphotase inhibitor cocktail (Sigma).

Transcription profiling of human stimulate neutrophils to investigate the impact of anti-inflammatory agents on the gene expression profiles

Project description:Adenosine, prostaglandin E2, or increased intracellular cyclic AMP concentration each elicit potent anti-inflammatory events in human neutrophils by inhibiting functions such as phagocytosis, superoxide production, adhesion and cytokine release. However, the endogenous molecular pathways mediating these actions are poorly understood. In the present study, we examined their impact on the gene expression profile of stimulated neutrophils. We have identified a set of genes that may be part of important resolution pathways that interfere with cell activation. Identification of these pathways will improve understanding of the capacity of tissues to terminate inflammatory responses and contribute to the development of therapeutic strategies based on endogenous resolution Experiment Overall Design: Neutrophils were resuspended at a concentration of 25 x 106 cells/ml in Hank's balanced salt solution (HBSS; 37Â°C) containing 1% fetal bovine serum, 10 mM HEPES pH 7.4, 1,6 mM Ca2+ and no Mg2+. Adenosine deaminase (ADA; 0.1U/mL) was added to cell suspensions 20 min prior to stimulation. Where mentioned, PGE2, CGS 21680, RO 20-1724 and forskolin, dissolved in DMSO, were added to cell suspensions 10 min before stimulation. The final organic solvent concentration was identical in all samples and did not exceed 0.1% (v/v). Neutrophils were stimulated with a mixture of LPS (100 ng/mL), GM-CSF (1.4 nM), TNF-Î± (100 ng/mL), fMLP (100 nM) and IL-1Î² (30 nM) for 30 min at 37oC. These experiments were performed 5 times in identical conditions, each time with a different donor.

iTRAQ dataset of Pseudomonas aeruginosa PAO1 following dially disulfide treatment

Project description:To establish the effect of DADS on the P. aeruginosa proteome, 50-mL LB medium samples were inoculated at 108 CFU/mL with exponential growth phase P. aeruginosa PAO1. DADS was then added at a concentration of 0 (control) or 0.64 mg/mL, in triplicate. The six experimental groups were incubated for 5 h in a water bath shaker at 37 ºC with a shaking rate of 180 rpm. Cells from the three control groups and three DADS treatment groups were then sampled and centrifuged. The cell precipitate from each experiment group was snap-frozen at -80 ºC.

Transcriptional profiling of Escherichia coli after addition of CORM-3 and iCORM-3 to aerobically and anaerobically growing cells

Project description:Escherichia coli strain MG1655 was grown in a New Brunswick Scientific Bioflow III Biofermentor under continuous culture (chemostat) conditions. Cells were grown in defined media containing 2 mM glycerol as the sole and limiting source of energy and carbon. The working volume was 200 ml, and the dilution rate 0.2 h-1. For aerobic growth, the air-flow rate was 0.1 l/min, and the dissolved oxygen tension was maintained at ~7% air saturation by measuring oxygen dissolved in the culture using a Broadley James D140 OxyProbe® electrode. For anaerobic growth, cells are grown on 100 % nitrogen gas bubbled at 0.1 l/min Cells were grown as above to steady-state, At steady-state, CORM-3 or iCORM-3 was added to the chemostat culture at a final concentration of 40 uM. Samples were taken immediately prior to the addition of CORM-3 or iCORM-3 and over a time course of 2.5, 5, 10, 20, 40 and 80 min exposure to (i)CORM-3 for subsequent analysis using microarrays. Cells were harvested directly into phenol:ethanol to stabilize RNA, and total RNA was purified using Qiagen’s RNeasy Mini kit as recommended by the suppliers.
