Project description:Untargeted UPLC-MS/MS data from a screen of human gut microbiome commensal isolate bacteria from healthy human donor feces. Isolates include Mediterraneibacter gnavus MSK15.77 (NCBI accession NZ_JAAIRR010000000), Bacteroides ovatus MSK22.29 (NCBI accession NZ_JAHOCX010000000), Bifidobacterium longum DFI.2.45 (NCBI accession NZ_JAJCNS010000000), and Lachnoclostridium scindens SL.1.22 (NCBI accession GCA_020555615.1). The dataset includes validated bile acid standards. All using positive ionization.
Project description:Regulation of EHEC gene expression by the gut commensal bacterium B. thetaiotaomicron. EHEC is a human pathogen that colonizes in the colon where B. thetaiotaomicron is a predominant commensal. We used microarrays to evaluate global regulation of EHEC when cultured with B. thetaiotaomicron.
Project description:Human CD14 positive monocytes were purified from major depressed patients or healthy volunteer frozen PBMC. Patients were treated with venlafaxine. Responders and non-responders to venlafaxine were recorded after 6 weeks of treatment
Project description:Human CD14 positive monocytes were purified from major depressed patients or healthy volunteer frozen PBMC. Patients were treated with imipramin. Responders and non-responders to imipramin were recorded after 6 weeks of treatment
Project description:Alterations in gut microbiota have been implicated in the pathogenesis of Colorectal Cancer (CRC). Here we collected fecal samples from 14 CRC patients and 14 healthy volunteer cohorts, and characterized their microbiota using label-free quantitative metaproteomics method. We have quantified 30,062 gut microbial protein groups, 91，902 peptides, and 195 genera of microbes, among which 341 proteins were found significantly different in abundance between the CRC patients and healthy volunteers. Our study demonstrates that gut bacteria involve in CRC pathogenesis not only via taxonomy abundance variations but also functional activity changes.
Project description:Carcinogenesis is a genetic process in which molecular changes occur earlier than histomorphological changes. The key to early detection of oral squamous cell carcinoma (OSCC) is to identify genetic alterations. However, aberrant lncRNA expression profiles in OSCC plasma is still largely unknown. Using an lncRNA microarray, we analyzed the aberrant lncRNA expression profiles in OSCC plasma compared with paired healthy volunteer plasma. Our data revealed 7473 differentially expressed (Fold Change >= 2.0, P-value <= 0.05) lncRNAs, among which 3972 lncRNAs were significantly up-regulated and 3501 lncRNAs were down-regulated in OSCC compared with paired healthy volunteer plasma.
Project description:Flagellins from commensal bacteria can be weak Toll-like receptor (TLR)5 agonists despite high affinity binding to TLR5, ligands we termed “silent flagellins”. To determine if silent flagellins are detectable in the human gut, endogenous flagellins produced by the microbiota were isolated from stool obtained from a healthy adult female donor. TLR5 was used as bait to enrich for silent flagellins and TLR5-bound flagellins were identified by searching peptides against a custom flagellin database built from metagenome sequences.
Project description:Human CD14 positive monocytes were purified from major depressed patients or healthy volunteer frozen PBMC. Patients were treated with Sertralin or Sertralin + Celecoxib. Responders and non-responders to Sertralin and Sertralin + Celecoxib were recorded after 6 weeks of treatment
Project description:Transcriptional profiling of human MSCs comparing control MSCs with parathyroid hormone (PTH)-stimulated MSCs. PTH-stimulated MSCs were treated with 0.1 nM recombinant human PTH (N-terminal fragment, amino acids 1-34) for 48 hours. Human MSCs were isolated from a bone marrow sample obtained from a healthy adult volunteer.
