MetabolomicsHighly sensitive feature detection for high resolution LC/MS

BACKGROUND: Liquid chromatography coupled to mass spectrometry (LC/MS) is an important analytical technology for e.g. metabolomics experiments. Determining the boundaries, centres and intensities of the two-dimensional signals in the LC/MS raw data is called feature detection. Fo...

MetabolomicsgeoRge: A Computational Tool To Detect the Presence of Stable Isotope Labeling in LC/MS-Based Untargeted Metabolomics
Studying the flow of chemical moieties through the complex set of metabolic reactions that happen in the cell is essential to understanding the alterations in homeostasis that occur in disease. Recently, LC/MS-based untargeted metabolomics and isotopically labeled metabolites have been used to facil...

MetabolomicsComparative LC/MS-based profiling of L-arginine producing, canavanine resistant Corynebacterium glutamicum strain ATCC 21831 and type strain ATCC 13032
Corynebacterium glutamicum strain ATCC 21831 is a producer of L-arginine that was created by random mutagenesis. It is resistant to the arginine structural analogue canavanine. In order to identify potential bottlenecks in the biosynthetic pathway that leads to this industrially important amino acid...

MetabolomicsComparative LC/MS-based profiling of silver nitrate-treated Arabidopsis thaliana leaves of wild-type and cyp79B2 cyp79B3 double knockout plants
Indole-3-acetaldoxime (IAOx) represents an early intermediate of the biosynthesis of a variety of indolic secondary metabolites including the phytoanticipin indol-3-ylmethyl glucosinolate and the phytoalexin camalexin (3-thiazol-2′-yl-indole). Arabidopsis thaliana cyp79B2 cyp79B3 double knockout pla...

TranscriptomicsRNA-seq of A431 cell line after gefitinib treatment
RNA sequencing of A431 cell line samples before and after gefitinib treatment, at 0, 2, 6 and 24 hours, was performed in order to characterize the cell line's early and late response to this drug, and to compare against proteomics (mass spectrometry) characterization of the cell line using the same ...

ProteomicsFast and accurate bacterial species identification in biological samples using LC-MS/MS mass spectrometry and machine learning (DDA dataset)
We have developed a new strategy for identifying bacterial species in biological samples using specific LC-MS/MS peptidic signatures. In the first training step, deep proteome coverage of bacteria of interest is obtained in Data Independent Acquisition (DIA) mode, followed by the use of machine lear...
