Proteomics and direct Protein-SIF of the bacterial ectosymbionts of the ciliate Kentrophoros sp. H

ABSTRACT: Kentrophoros ciliates are found worldwide in coastal marine sediment, and have an obligate symbiosis with sulfur-oxidizing Gammaproteobacteria called Candidatus Kentron. The genomes of different Kentron species suggest that they are chemolithoheterotrophs, producing new biomass from organic carbon substrates. We investigated the metaproteome of Kentrophoros sp. H and its symbiont (from two sites in the Mediterranean), to verify that hypothesized pathways of carbon and energy metabolism are indeed expressed, and to estimate the stable isotope fractionation in biomass, which can be a signature of the carbon sources used by the organism.

Labeling Escherichia coli to saturation with 2.5 % of 15N ammonium in two conditions (aerobic and anaerobic) for benchmarking of protein-based stable isotope probing proteomics (Protein-SIP)

Project description:This dataset is part of a study aimed at developing algorithms for the quantification of stable isotope content in microorganisms after labeling them with stable isotope-labeled substrates. For this dataset Escherichia coli cultures were labeled with 2.5 % of 15N-labeled NH4Cl and grown either anaerobically or aerobically. Cultures of E. coli were grown in M9 minimal medium in which 2.5 % of the ammonium was replaced with 15N-labeled NH4Cl for >10 generations to achieve close to complete labeling of cells. Triplicate cultures were grown. Please note that the unlabeled ammonium that was used of course had a natural content of 15N of around 0.4 %, thus the 0% added label samples have an actual 15N content of 0.4 % and all added label is on top of this value. We included a tab delimited table with this submission providing details on all raw files.

Mixing of Escherichia coli cells labeled with 13C glucose with unlabeled E. coli cells for benchmarking of protein-based stable isotope probing proteomics (Protein-SIP)

Project description:This dataset is part of a study aimed at developing algorithms for the quantification of stable isotope content in microorganisms after labeling them with stable isotope-labeled substrates. In this dataset Escherichia coli cultures were labeled with different percentages (1% or 10%) of either single-carbon 13C glucose (13C2) or fully-labeled 13C glucose (13C1-6). Labeled cells were subsequently mixed with unlabeled E. coli cells in fixed ratios (50%, 90%, 95%, 99%). Cultures of E. coli were grown in M9 minimal medium in which a percentage of the glucose was replaced with 13C2 or 13C1-6 glucose for >10 generations to achieve close to complete labeling of cells. Triplicate cultures were grown for each percentage. Please note that the unlabeled glucose that was used of course had a natural content of 13C of around 1.1%, thus the 0% added label samples have an actual 13C content of 1.1% and all added label is on top of this value. We included a tab delimited table with this submission providing details on all raw files.

TEL-AML1 (ETV6-RUNX1) in B-cells and leukemia (part 3)

Project description:We identified directly and indirectly regulated target genes utilizing an inducible TEL-AML1 system derived from the murine pro B-cell line BA/F3 and a monoclonal antibody directed against TEL-AML1. By integration of promoter binding identified with ChIP-on-chip, gene expression and protein output through microarray technology and stable labelling of amino acids in cell culture (SILAC), we identified directly and indirectly regulated targets of the TEL-AML1 fusion protein. Bound promoter regions of immunoprecipitated AML1 associated genes were first compared to input material and enrichment was calculated. The same was performed for empty vector control cell lines, also treated with the induction reagent mifepriston. Enriched promoter regions were then compared of the both sets. 3 independent replicates each (6 arrays) were performed.
