MetabolomicsMonitoring recombinant protein expression in bacteria by rapid evaporative ionisation mass spectrometry

RATIONALE: There is increasing interest in methods of direct analysis mass spectrometry that bypass complex sample preparation steps.

METHODS: One of the most interesting new ionisation methods is rapid evaporative ionisation mass spectrometry (REIMS) in wh...

ProteomicsProteomic Profile of Daphnia pulex using Data-Independent Acquisition Mass Spectrometry and Ion Mobility Separation
In this study, various sample preparation and mass spectrometry acquisition methods were performed for the purpose of improving Daphnia pulex proteome exploration. We observed benefits for employing both in-gel and in-solution methods of trypsin digestion. Furthermore, data independent acquisition m...

ProteomicsBALF exosomes - Pulmonary Sarcoidosis is Associated With Exosomal Vitamin D-Binding Protein and Inflammatory Molecules
Using 8-plex iTRAQ labelling exosmes isolated from bronchial lavage (BALF) were analyzed by LC-MS/MS. The measurements compared control subjects with sarcoidosis patients (15 in all) ; five with löfgrens syndrome and 10 with regular sacroidosis

ProteomicsProteotyping of microbial communities reveals the correlations between the microorganisms and the process parameters
Background: Methane yield and biogas productivity of biogas plants depend on microbial community structure and functionality, substrate supply, and general process parameters. Little is known, however, about the correlations between microbial community function and the process parameters. To close t...

TranscriptomicsGlobal changes in the nuclear positioning of chromatin domains and genomic interactions that orchestrate B cell fate
The genome is folded into domains that are located in either transcriptionally inert or permissive compartments. Here we used genome-wide strategies to characterize domains during B cell development. Structured Interaction Matrix Analysis revealed that CTCF occupancy was primarily associated with i...

ProteomicsMetaproteomics of fecal samples supports the diagnosis of Crohn’s Disease and Ulcerative Colitis
Objective Crohn’s Disease (CD) and Ulcerative Colitis (UC) are chronic inflammatory diseases of the gastrointestinal tract. Reliable diagnosis of these diseases requires a comprehensive examination of the patient, which include invasive endoscopy. This study assesses whether non-invasive LC-MS/MS ba...

ProteomicsBeta-cell Galphas signaling is critical for physiological and pharmacological enhancement of insulin secretion
Islet lysates were adjusted to 5 percent SDS in TEAB, pH 8.5, reduced and alkylated and digested with modified trypsin (Worthington) using an S-trap mini device (Protifi). Peptides were labeled with TMT16 reagents (lot ZH350094). Phosphopeptide enrichment used GL Sciences p10 TiO tips. LC-MS/MS used...

TranscriptomicsTranscription profiling of endotoxin-stimulated human monocytic cells in presence and absence of host defense peptide LL-37
The objective of the study was to evaluate transcriptional response of endotoxin-stimulated human monocytic cells in presence and absence of host defense peptide LL-37. A functional genomics approach was used to establish a temporal transcriptional profile and identify differentially expressed gene...

TranscriptomicsTranscription profiling of human monocytic cells THP-1 stimulated with LPS (10ng/ml) in presence or absence of LL-37 (5 ug/ml), as well as with the peptide alone, for 4 hours
The objective of the study was to evaluate transcriptional response of endotoxin-stimulated human monocytic cells in presence or absence of host defense peptide LL-37 at low physiologically relevant concentrations. Human monocytic cells THP-1 were stimulated with LPS (10ng/ml) in presence or absenc...
