Project description:Dear Sir or Madam, we report an in-depth proteogenomics study of Helicobacter pylori strain 26695 and provide the supporting MS data via ProteomExchange. The study includes 2 biological replicates with 6 different datasets: G1: in-gel digestion with trypsin, replicate 1 G2: in-gel digestion with trypsin, replicate 2 T1: SEC fractionation of low molecular weight (LMW) proteins and subsequent trypsin digestion, replicate 1 T2: SEC fractionation of LMW proteins and subsequent trypsin digestion, replicate 2 A1: SEC fractionation of LMW proteins and subsequent AspN digestion, replicate 1 A2: SEC fractionation of LMW proteins and subsequent AspN digestion, replicate 2 L1: SEC fractionation of LMW proteins and subsequent LysC digestion, replicate 1 L2: SEC fractionation of LMW proteins and subsequent LysC digestion, replicate 2 In our proteogenomics approach, we could identify four previously missing protein annotations and were able to correct sequences of six protein coding regions. Furthermore we identified signal peptidase cleavage sites for 72 different proteins. MGFs were generated by Maxquant 1.1 [1] using recalibration of peptide parent masses. For PRIDE (http://www.ebi.ac.uk/pride) submission, we made an additional database search with Mascot and X!Tandem using the SearchGUI [2]. Therefore we searched against a NCBI database of H. pylori strain 26695 complemented with the sequence corrections, signal peptide cleavage sites and missing annotations with the same configurations as described in materials and methods. For pride xml export we used the software PeptideShaker (http://code.google.com/p/peptide-shaker/). The complemented database has entries which will be submitted to the UniProtKB via SPIN. The entries have the according SPIN number as accession number. The NCBI accession numbers for the shortened sequences due to signal peptide cleavage are extended with “_1”. The fasta database is added to the submission.

Project description:Helicobacter pylori (H. pylori) is a human pathogen that infects almost half of the world’s population. Infection with H. pylori is frequently associated with chronic gastritis and can even lead to gastric and duodenal ulcers and gastric cancer. Although the persistent colonization of H. pylori and the development of H. pylori-associated gastritis remain poorly understood, it is believed that, in gastric mucosa, the modulated gastric epithelial cells (GECs) by H. pylori are key contributors. We used microarrays to detail the global programme of gene expression in Helicobacter pylori infected-gastric epithelial cell line AGS cells and identified up-regulated genes induced by Helicobacter pylori infection.

Project description:Helicobacter pylori infection reprograms host gene expression and influences various cellular processes, which have been investigated by cDNA microarray in vitro culture cells and in vivo patients of the chronic abdominal complaint. In this study，the effects of H. pylori infection on host gene expression in the gastric antral mucosa of patients with chronic gastritis were examined.

Project description:In this study transcriptional start sites (TSS) for H. pylori 26695 were determined To detect the complement of transcripts expressed from H. pylori, we collected three independent biological replicates (B1 – B3) from 26695 wild type strain grown to mid-exponential (OD 600 ~0.6) phase under microaerophilic conditions at 37°C in BHI medium. For all three samples, total RNA was extracted and subjected to differential RNA-seq (dRNA-seq) library preparation for primary transcriptome analysis as described previously (Sharma et al., 2010). Specifically, prior to cDNA library construction half of each RNA sample was treated with 5’ terminator exonuclease (+TEX samples), which degrades RNAs containing a 5’-monophosphate (5’-P) and, thus, enriches for primary transcripts containing 5’-triphosphates (5’-PPP). The other half of each sample was left untreated (-TEX samples) and thus contains both primary transcripts (5’-PPP) and processed RNAs (5’-P).
