Dataset Summary
TitleAn interactive mass spectrometry atlas of histone posttranslational modifications in T-cell acute leukemia
DescriptionThe holistic nature of omics studies makes them ideally suited to generate hypotheses on health and disease. Sequencing-based genomics and mass spectrometry (MS)-based proteomics are linked through epigenetic regulation mechanisms. However, epigenomics is currently focused on DNA methylation status using sequencing technologies, while studying histone posttranslational modifications (hPTMs) using MS is lagging, in part because reuse of raw data is impractical. Yet, it is established that targeting these hPTMs using epidrugs is a promising research avenue in cancer treatment. Therefore, we present the most comprehensive MS-based preprocessed hPTM atlas to date, including 21 T-cell acute lymphoblastic leukemia cell lines. We present the data in an intuitive and browsable single licensed Progenesis QIP project and provide all essential quality metrics, allowing users to assess the quality of the data, edit individual peptides, try novel annotation algorithms and export both peptide and protein data for downstream analyses, exemplified by the PeptidoformVisualization tool. This dataset sets the stage for generalizing MS-based histone analysis and provides the first reusable histone dataset for epidrug development.
