ProteomicsSimulated phosphopeptide spectral library for confident site localization
We have developed a new workflow to unambiguously localize phosphorylation sites on proteins. We demonstrate that spectral matching of phosphopeptide datasets against a library of the well-simulated spectra provided higher sensitivity for confident site localization than other tested programs. To co...

ProteomicsSimulated spectral library searching on TripleTOF phosphopeptide datasets
Synthetic phosphopeptides and enriched K562 cell phosphopeptides were analyzed using a TripleTOF 6600 mass spectrometer before and after enzymatic dephosphorylation. Dephosphorylated peptides identified by X!Tandem database searching were subjected to spectral simulation of all possible single phosp...

ProteomicsProlonged exposure to simulated microgravity promotes stemness impairing morphological, metabolic and migratory profile of pancreatic cancer cells: a comprehensive proteomic, lipidomic and trascriptomic analysis
Gravitational biology and its effects on cancer cells are of great interest, especially today that space is more accessible than ever. Despite advances in space research, little is known about the impact of microgravity on tumor and its biology and data from the literature are often contradictory du...

MetabolomicsCASMDB: An Open-Source Database of Metabolite Annotation Data for 1D 1 H NMR-Based Metabolomics
In metabolomics analyses, databases are invaluable for the identification of individual metabolites in experimentally collected samples. Publicly available databases for NMR-based metabolomics are unfortunately incomplete with respect to experimental conditions, such as pH, temperature, and NMR fiel...

ProteomicsHeLa phosphoproteome regulated by PP2A related proteins
HeLa cells were treated with siRNAs of PP2A related proteins or with okadaic acid, in triplicates. Tryptic digests of extracted proteins were analyzed using a Q Exactive mass spectrometer, before and after TiO2 phosphopeptide enrichment. Data were searched with Mascot via Proteome Discoverer. For ph...
