Project description:D-galactose orally intake ameliorate DNCB-induced atopic dermatitis by modulating microbiota composition and quorum sensing. The increased abundance of bacteroidetes and decreased abundance of firmicutes was confirmed. By D-galactose treatment, Bacteroides population was increased and prevotella, ruminococcus was decreased which is related to atopic dermatitis.
Project description:Applying a gel-based proteomic approach, the dynamic changes in root proteins of drought treated Quercus ilex subsp. Ballota [Desf.] Samp. seedlings were followed. Water stress was applied on 20 day-old holm oak plantlets by water limitation for a period of 10 and 20 days, each followed by 10 days of recovery. Root proteins were extracted using trichloroacetate/acetone/phenol protocol and subjected to two-dimensional electrophoresis. Coomassie colloidal stained gel images were analysed and spot intensity data subjected to multivariate statistical analysis. Selected consistent spots in the three biological replicas, presenting significant changes under stress, were subjected to MALDI-TOF mass spectrometry (peptide mass fingerprinting and MS/MS). For protein identification, combined search was performed with MASCOT search engine over NCBInr Viridiplantae and Uniprot databases. Taxonomy Holm oak (Quercus ilex subsp. Ballota [Desf.] Samp.). Dentro de Q. ilex hay dos subespecies, ilex ilex e ilex Ballota.
Project description:Global top-down proteomics LCMS analysis of proteins purified from soybean root nodules infected with either WT or nifH- mutant Bradyrhizobium japonicum. Raw LCMS data were processed with TopPIC; combined proteoform-spectral-matches, and label free quantitation results are included as separate csv files ("*_all_PrSMs.csv", "*_LFQ_Table.csv"). Also includes MALDI-Orbitrap data of intact proteins. The MALDI raw files and xml files can be loaded into imaging software for viewing ion images. Representative summed spectra are included separately in two "IMAGE-avg11567_from100to200min.raw" files. More detailed analysis and representative proteoform ion images are discussed in the associated manuscript. For sample processing, frozen tissue were homogenized for LCMS and proteins were extracted with the MPlex protocol. For MALDI, frozen tissues were sliced and embedded on ITO slides and sprayed with DHA matrix. LCMS data were processed with TopPIC and TopPICR. Imaging data were collected with Spectroglyph software.
