MetabolomicsStable Isotope–Assisted Plant Metabolomics: Combination of Global and Tracer-Based Labeling for Enhanced Untargeted Profiling and Compound Annotation
Untargeted approaches and thus biological interpretation of metabolomics results are still hampered by the reliable assignment of the global metabolome as well as classification and (putative) identification of metabolites. In this work we present an liquid chromatography-mass spectrometry (LC-MS)-b...

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...

MetabolomicsPronounced uptake and metabolism of organic substrates by diatoms revealed by pulse-labeling metabolomics
Diatoms contribute as a major group of microalgae to approximately 20% of the global carbon fixation. In the plankton, these algae are exposed to a plethora of metabolites, especially when competing algae are lysed. In line with evidence that these phototrophs can also engage in heterotrophy we aske...

TranscriptomicsInfluence of RNA Labeling on Expression Profiling of MicroRNAs
Several technical parameters are now being optimized for microRNA expression profiling experiments, but the finite amount of total RNA available continues to bottleneck clinical investigations. We used microarrays to determine the influence of the labeling reagent on total RNA requirements and data ...

Metabolomics13C-glucose tracing analysis of IFN-treated A549 cells expressing wild-type SARS-CoV-2 Nsp3-4 or a deISGylation-defective Nsp3-4 mutant protein

Interferon (IFN)-stimulated gene 15 (ISG15) regulates diverse cellular processes, including antiviral immunity, through its conjugation to target proteins (ISGylation). Increasing evidence suggests that ISGylation can also reshape cellular metabolism; however, how viruses counteract ISGylation-me...

ProteomicsDecreasing Protein Biotinylation Background in a Diatom Facilitates Proximity Labeling of the Periplastidial Compartment Proteome
Diatoms are ecologically and industrially significant microalgae, crucial for global carbon fixation and biotechnological applications. Their complex plastid membrane structures, resulting from secondary endosymbiosis, remain poorly characterized, particularly the periplastidial compartment (PPC). P...

ProteomicsTunable activated esters for lysine labeling in proteome
The development of various heteroaromatic activated esters designed for selective lysine labeling within the proteome for profiling purposes. Through systematic optimization of the reactivity and selectivity of these esters, we identified a series of effective probe molecules suitable for both in vi...
