The incorporation and localisation of 133Cs in a plant cellular model and the metabolic response induced were analysed as a function of external K concentration using a multidisciplinary approach. Sucrose-fed photosynthetic Arabidopsis thaliana suspension cells, grown in a K-containing or K-depleted medium, were submitted to a 1 mM Cs stress. Cell growth, strongly diminished in absence of K, was not influenced by Cs. In contrast, the chlorophyll content, affected by a Cs stress superposed to K d ...[more]

circITGB6-pulled down proteins in A549 cells

Project description:A549 cells were transfected with 100 pmol DNA probes complementary to the back-splice site of circITGB6 or PDPN 3’UTR region. 24 h later, cells were washed with PBS and lysed with the lysis buffer (150 mM NaCl, 20 mM Tris-HCl, pH 7.5, 1.5 mM MgCl2, 0.5% NP-40, 0.5% Triton X-100, 10% glycerol, RNase inhibitors (Thermo Scientific), protease and phosphatase inhibitor cocktails). Pre-treated streptavidin magnetic beads were incubated with cell lysates at 4°C for 1 h, followed by washing five times with the washing buffer (20 mM Tri-HCl, pH7.5, 1 mM EDTA and 450 mM NaCl) and elution with Laemmli sample buffer. The circITGB6- or PDPN mRNA- interacting proteins were subjected to SDS-PAGE and visualized by coomassie blue staining or immunoblot analysis. Protein bands were excised and identified by LC-MS/MS mass spectrometry and Proteome Discoverer software (version 1.4; Thermo Scientific).

Bacillithiol as Part of the Response of Staphylococcus aureus to Oxidative Stress

Project description:Overnight cultures of wild type COL or the bshA mutant were back-diluted to an O.D.650 of 0.1 in 30 mL of TSB. The cells were grown at 37C with shaking in a 300mL flask until they reached an O.D.650 of 1.1. The cells were then equally separated into 50mL Falcon tubes, so that each tube had 10mL of culture. One tube for each strain was induced with 1 mM diamide and one with 10 mM H2O2, which we did not send for analysis. All cultures were allowed to continue growing at 37C with shaking for another 20 minutes. RNA extractions were carried out as previously described in Tamber et al., Infect Imunn, 2010.

Transcription profiling of Arabidopsis wild type and WRKY33 mutants after salt stress to identify WRKY33 target genes

Project description:Arabidopsis thaliana, wild-type (Col-0) and a T-DNA insertion mutant of WRKY33 gene(SALK_006603, designated as wrky33-1),were hydroponically cultured for 20 d and treated by 150 mM NaCl for 6 h. Roots were harvested and a QiagenOperon oligonucleotide microarray(v1.0.3) was used to identify differentially expressed genes in wrky33-1 mutant compared to wild-type.

Effects of benfotiamine in cultured human myotubes exposed to both normal and high glucose cencentrations

Project description:The aim of the present work was to study the effects of benfotiamine (S-benzoylthiamine O-monophosphate) upon glucose and lipid metabolism and gene expression in differentiated human skeletal muscle cells (myotubes) incubated for 4 days under normal (5.5 mM glucose) and hyperglycemic (20 mM glucose) conditions. Myotubes established from lean, healthy volunteers were treated with benfotiamine for 4 days. Glucose and lipid metabolism were studied with labeled precursors. Gene expression was measured using real time polymerase chain reaction (qPCR) and microarray technology.

Mycobacterium tuberculosis under nitric oxide stress

Project description:To study the entire transcriptional and translational M. tuberculosis response from initial survival to eventual escape from nitric oxide (NO) stress, we exposed exponentially growing M. tuberculosis to 1 mM diethylenetriamine/nitric oxide (DETA/NO) and followed the adaptive response over 48 hours. Samples were obtained from two independent experiments performed in triplicate and we sampled aliquots for transcriptome profiling by RNA sequencing at 20 min, 2 h and 24 h and for mass spectrometry-based shotgun proteomics at 20 min, 40 min, 1 h, 2 h, 4 h, 8 h, 12 h, 24 h and 48 h post NO exposure.

Untargeted metabolomics on control and compound-treated STHdhQ111 cells and control STHdhQ7 cells

Project description:Cells expressing mutant huntingtin were treated in triplicate with serum-free DMEM with vehicle (Q111SST) or serum-free DMEM with one of 14 protective compounds for 24 hours. Wild type cells were also treated with serum-free DMEM with vehicle (Q7SST) as an additional control for 24 hours. We examined the compounds' metabolomic effects on the cells using untargeted mass spectrometry, which measured lipids and polar metabolites.
