Toxicol. The Biomarkers, EndpointS and other Tools (BEST) resources developed by the FDA-NIH Biomarker Working Group is a valuable resource which classifies and defines biomarker categories and also describes biomarker validation and qualification [Citation138]. Schirle, M., Bantscheff, M. & Kuster, B. Mass. Table 1 describes several types of biomarkers used in drug development, as defined in the BEST document as well as examples from the BEST document and literature, with an emphasis on protein and proteomics related biomarkers.

Google Scholar. Article Similar to SCoPE-MS, Tsai et al. Proteom. Ong, S.-E. et al. A dendritic cell vaccine increases the breadth and diversity of melanoma neoantigen-specific T cells. At the same time, the increasing interest in more disease-relevant cellular models for phenotypic screening, such as complex organoid systems and patient-derived primary cells, makes the considerations in this review regarding increased sensitivity in MS instrumentation and the development of single cell proteomics workflows particularly relevant in this area as well. These therapeutically relevant dark matter antigens are of interest for both cancer vaccine and T cell therapy approaches, where common, tumor specific antigens represent ideal targets. 14, 15741586 (2015). Chem. A dynamic protein interaction landscape of the human centrosome-cilium interface. ACS Chem. Drug Discov.

While immunoassays and targeted MRM MS assays are widely used for clinical assays, the choice of platform ultimately depends on the use case for the biomarker. Science 358, eaan4368 (2017). While these resources have proven invaluable to early target identification, as targets get closer to clinical trials protein expression must be validated to limit potential toxic effects of therapeutic intervention. The challenges associated with clinical validation are likely enough to discourage replication unless a clear, cost effective use case can be made. In the near future, it is possible that a sufficiently sophisticated deep learning algorithm could consider an MS spectrum, retention time, and collisional cross section to predict a peptide sequence without performing a database search. J. Proteome Res. For example, recent improvements in MS instrumentation led to the number of peptides sequenced per outpacing available candidates for sequencing leading to lost instrument time [Citation21]. Biol.

The Multiplexed Proteome Dynamics Profiling (mPDP) workflow further allows additional differentiation of direct compound-induced protein degradation from downstream effects and has been used, e.g., to compare the effects of the heterobifunctional JQ1-VHL degrader vs. the bromodomain inhibitor JQ1 alone [Citation120]. Drug Discov. Sun, R. et al. Another orthogonal strategy to increase proteome coverage is to utilize enrichment approaches for PTMs. Building upon the MassIVE Knowledge Base [Citation65], MassIVE.quant includes experimental design information commonly lacking in public data repositories. By focusing on low-level phospho-tyrosine and immunopeptidomic samples they demonstrate that quantitative dynamic range decreases 2 to 6-fold when a carrier proteome is employed. While these are becoming increasingly available, including for lysine [Citation97], methionine [Citation98] and tyrosine [Citation99], the identification of novel probes that are more robust and allow access to additional amino acids remains of high importance. Proc. 16, 424440 (2017). Spectrom. Methods 10, 186187 (2013). A promiscuous biotin ligase fusion protein identifies proximal and interacting proteins in mammalian cells. Proteogenomics utilizes a combination of proteomics, genomics, and transcriptomics to aid in the discovery and identification of peptides and proteins and pathways evolved a number of years ago [Citation41]. As the number of TAAs targeted for therapeutic intervention increases, the chance that therapies identify low levels of TAA expression in normal tissues increases. Proteomics, post-translational modifications, and integrative analyses reveal molecular heterogeneity within medulloblastoma subgroups. Due to this, MassIVE.quant represents an opportunity for biological findings to be more readily discovered in previously acquired, publicly available data. 10, 5715 (2019). Sci. Canon, J. et al.

Pharmacol. Reinhard, F. B. M. et al. Plasma proteomics, in particular, has been an area of intense focus because blood is readily available, it perfuses the entire body thus providing the opportunity to identify biomarkers across a broad range of diseases and disorders, and because clinical analysis of blood is already a well-established, common diagnostic procedure. Chem. Nucleic Acids Res. For example, emerging engineered T cell therapies target tumor-associated antigens that have increased protein levels in cancer tissue as compared to normal tissue [Citation66,Citation67]. In embarking on assembling this review, we dissected the literature and interviewed colleagues for where they see this field evolving and having an influence in biotechnology and pharmaceutical research. Cox, J.
