Proteomic analysis of fluids from the genital tract of ewes during the estrous cycle

ABSTRACT: Fluids samples of oviduct, uterus and cervical mucus were collected in sheep D0 (J0) and D10 (J10) in spontaneous (N) and synchronized (I) by flushing with PBS 1X. Proteins for each fluid were included in-gel (3-4 bands) followed by Coomassie Blue staining. After reduction and alkylation, proteins were in-gel digested with trypsin and peptide mixtures were analyzed by nanoLC-MS/MS using LTQ velos Orbitrap mass spectrometer. Raw data files were converted to MGF with Proteome Discoverer software (version 1.2; Thermo Fischer Scientific, San Jose, USA). Precursor mass range of 350-5000 Da and signal to noise ratio of 1.5 were the criteria used for generation of peak lists. In order to identify the proteins, the peptide and fragment masses obtained were matched automatically against the mammalia section of a locally maintained copy of nr NCBI (01/01/2013). MS/MS ion searches were performed using MASCOT Daemon and search engine (version 2.3; Matrix Science, London, UK). The parameters used for database searches include trypsin as a protease with allowed two missed cleavage, carbamidomethylcysteine (+57 Da), oxidation of methionine (+16) and N-terminal protein acetylation (+42) as variable modifications. The tolerance of the ions was set to 5 ppm for parent and 0.8 Da for fragment ion matches

The female genital tract includes several anatomical regions whose luminal fluids successively interact with gametes and embryos and are involved in the fertilisation and development processes. The luminal fluids from the inner cervix, the uterus and the oviduct were collected along the oestrous cycle at oestrus (Day 0 of the cycle) and during the luteal phase (Day 10) from adult cyclic ewes. The proteomes were assessed by GeLC-MS/MS and quantified by spectral counting. A set of 940 proteins wer ...[more]

Project description:Many protein activities are driven by ATP binding and hydrolysis. Here, we explore the ATP binding proteome of the model plant Arabidopsis thaliana using Acyl-ATP (AcATP) probes. These probes target ATP binding sites and covalently label lysine residues in the ATP binding pocket. Protein extracts were labelled with NHS-LC-Biotin, purified over neutravidin and eluted with formic acid. Eluted proteins were separated by 1-D SDS Gel and digested with Trypsin. Peptide mixtures were analysed by LC-MS/MS on an LTQ Velos. Spectra were searched using Mascot 2.3 using a fixed modification of cysteine (57.02 Da for carbamidomethyl), and variable modifications of methionine (15.99 Da for oxidation) and lysine (339.16 and 355.16 Da for BHAc and OBHAc labeling, respectively). A mass tolerance was set to 0.3 Da for the precursor ions and 0.4 Da for fragment ions. Up to two mis-cleavages for trypsin were permitted since the labeling would prevent cleavage at the labeled lysine. The MS2 spectra were searched against the TAIR10_pep_2012 (version November 2012) containing 35386 proteins of Arabidopsis thaliana, supplemented with a small database with 1095 artefact proteins and a reversed decoy database of the same proteins (totals 72962 entries). An oxidized version of the modifier was observed. Alternatively Arabidopsis leaf proteome was labeled with desthiobiotin-acyl ATP and digested with trypsin. Labeled peptides were purified on streptavidin matrix and sequenced by LC-MS/MS on an LTQ linear ion trap. Here the MS2 spectra were searched using SEQUEST against the TAIR9_pep_20090619 database (version June 2009) containing 32,769 proteins of Arabidopsis thaliana. MS2 searches included fixed iodoacetamide modification of cysteine (57 Da for alkylation), and variable modifications of methionine (16 Da for oxidation) and lysine (196 Da for DBAcATP labeling). Up to three mis-cleavages with trypsin were allowed and non-tryptic or half-tryptic peptides were excluded. A mass tolerance was set to 3 Da for the precursor ions and 1 Da for fragment ions.

Project description:Brachypodium distachyon is a new model plant for wheat, barley and several potential biofuel grasses. The Bd21 leaf was initially treated with salt concentrations ranging from 80 to 320 mM followed by a recovery process prior to proteome analysis. Leaf total protein was extracted according to the method of Wang et al. with minor modifications, followed by 2D DIGE separation as recommended by the manufacturer (GE Healthcare). The differentially expressed proteins spots were identified using ImageMaster 2D Platinum Software Version 5.0 (Amersham Biosciences). Protein identification was carried out by the ABI 4800 Proteomics Analyzer MALDI-TOF/TOF (Applied Biosystems, Foster City) operating in a result-dependent acquisition mode. Peptide mass maps were acquired in positive ion reflector mode (20 kV accelerating voltage) with 1000 laser shots per spectrum. Monoisotopic peak masses were automatically determined within the mass range 800-4000 Da with a signal to noise ratio minimum set to 10 and a local noise window width of m/z 250. Up to five of the most intense ions with minimum signal to noise ratio 50 were selected as precursors for MS/MS acquisition, excluding common trypsin autolysis peaks and matrix ion signals. In MS/MS-positive ion mode, spectra were averaged, collision energy was 2 kV, and default calibration was set. Monoisotopic peak masses were automatically determined with a signal to noise ratio minimum set to 5 and a local noise window width of m/z 250. The MS together with MS/MS spectra were searched against NCBI Brachypodium protein database (26035 entries in total, downloaded on July 16, 2011) using the software MASCOT version 2.1 (Matrix Science) with the following parameter settings: trypsin cleavage, one missed cleavage allowed, carbamidomethylation set as fixed modification, oxidation of methionines and phosphorylation of serine, threonine, and tyrosine allowed as variable modification, peptide mass tolerance set to 100 ppm and fragment tolerance set to ± 0.3 Da. All searches were evaluated based on the significant scores obtained from MASCOT. The results were creditable with Protein Score C. I. % and Total Ion Score C. I. % both above 95% and significance threshold p < 0.05 for the MS/MS.
