Project description:The SZ-4 cell was originally identified in a Sezary disease patient and expresses FOXP3. There are different subclones of SZ4 cell which have different expression of FOXP3. Here, we used FOXP3 positive and negative SZ4 cell lines to do miRNA microarray.
Project description:The Gene Ontology (GO) is the most widely used ontology for creating biomedical annotations. GO annotations are statements associating a biological entity with a GO term. These statements comprise a large dataset of biological knowledge that is used widely in biomedical research. GO Annotations are available as "gene association files" from the GO website in a tab-delimited file format (GO Annotation File Format) composed of rows of 15 tab-delimited fields. This simple format lacks the knowledge representation (KR) capabilities to represent unambiguously semantic relationships between each field. This paper demonstrates that this KR shortcoming leads users to interpret the files in ways that can be erroneous. We propose a complementary format to represent GO annotation files as knowledge bases using the W3C recommended Web Ontology Language (OWL).
Project description:The data set contains MS/MS data on teeth extracts for Ancient DNA teeth samples ran in both positive and Negative ionization modes
Project description:Seeds of Arabidopsis thaliana wild type and knockout-mutants for flavonoid genes (tt7 [3 lines], fls1, tt3, tt4, tt7tt4 [2 lines] ) were subjected to untargeted metabolomic analyses (LC-MS/MS) in positive and negative ionisation mode.
Project description:Secondary metabolite profiles of Aspergillus fumigatus aneuploids, WT, and nscROE strains under FK506 stress. Data include both positive and negative ionization modes from a 25-minute reverse-phase run conducted in 2025.
Project description:<p>Gallbladder cancer (GBC) is an aggressive malignancy often associated with gallstones (GBCGS), a condition distinct from gallstone disease (GSD). Both GBC and GBCGS are rare, with unclear pathogenesis and no established biomarker-based solutions. This pilot study aimed to identify distinct metabolic signatures in GBC and GBCGS for early diagnosis and stratification of high-risk GSD patients. A comparative untargeted serum metabolomic profiling was performed across three patient groups: GBC (n1=9), GBCGS (n2=11), and GSD (n3=10). A total of 35,385 mass-features in both positive and negative ionization modes with MS/MS characteristics were detected and annotated into 736 biochemicals.</p>
Project description:Punarnava [Boerhaavia diffusa L.] is a medicinal plant and constituent of several Indian traditional medicines. According to Ayurveda, this plant is a rich source of nutrients. Traditionally, it is used to provide relief against various gastrointestinal disorders, treat wounds, reduce joint pains, and as an anti-stress agent. Despite its pharmacological importance, detailed characterization of the metabolite composition of this plant has not been reported to date. Therefore, we have taken up metabolomic profiling of Punarnava choorna, as part of a larger project of metabolomic profiling of ayurvedic drugs. We carried out a global metabolomic analysis using a high-resolution mass spectrometry to investigate metabolite composition of Punarnava choorna. In total 1747 and 4031 features were identified at MS1 using XCMS in the positive and negative modes, respectively. Using MS2Compound, we identified 1229 and 709 features in the positive and negative modes, respectively. We also identified 362 and 191 metabolites at MS2 level in the positive and negative modes, respectively using the MS2Compound tool. The data were searched against the PlantCyc, KEGG, PhenolExplorer and HMDB databases. A large number of nutritionally important metabolites including amino acids, sugars and vitamins were identified in Purnarnava choorna. Further, the identified metabolites were mapped to their potential protein interactors using BindingDB tool. Highest number of interactions was observed for plant serotonins. The data provides molecular evidence to accelerate the discovery of mode of action of Purnarnava choorna.
