Abstract

Somatic mutations have been extensively characterized in breast cancer, but the effects of these genetic alterations on the proteomic landscape remain poorly understood. Here we describe quantitative mass-spectrometry-based proteomic and phosphoproteomic analyses of 105 genomically annotated breast cancers, of which 77 provided high-quality data. Integrated analyses provided insights into the somatic cancer genome including the consequences of chromosomal loss, such as the 5q deletion characteristic of basal-like breast cancer. Interrogation of the 5q trans-effects against the Library of Integrated Network-based Cellular Signatures, connected loss of CETN3 and SKP1 to elevated expression of epidermal growth factor receptor (EGFR), and SKP1 loss also to increased SRC tyrosine kinase. Global proteomic data confirmed a stromal-enriched group of proteins in addition to basal and luminal clusters, and pathway analysis of the phosphoproteome identified a G-protein-coupled receptor cluster that was not readily identified at the mRNA level. In addition to ERBB2, other amplicon-associated highly phosphorylated kinases were identified, including CDK12, PAK1, PTK2, RIPK2 and TLK2. We demonstrate that proteogenomic analysis of breast cancer elucidates the functional consequences of somatic mutations, narrows candidate nominations for driver genes within large deletions and amplified regions, and identifies therapeutic targets.

  • Contemporary proteomic research relies heavily on high-resolution mass spectrometry (HR-MS) platforms including Orbitrap and time-of-flight (TOF) systems.

    “Contemporary proteomic research relies heavily on high-resolution mass spectrometry (HR-MS) platforms including Orbitrap and time-of-flight (TOF) systems.”

    From Artificial intelligence-driven multi-omics approaches in Alzheimer's disease: Progress, challenges, and future directions (2025) · cites this paper as [169]

    The ‘Proteogenomic analysis of TCGA samples’ section says the study used high-resolution, accurate-mass tandem mass spectrometry for breast-tumor proteomics. The Introduction also describes mass spectrometry as a means of analyzing tumor proteomes. Our copy does not identify Orbitrap or time-of-flight systems or establish how heavily proteomic research generally relies on them. (LLM, conf=0.85)

  • AI-based analytical methods are increasingly used for enrichment, site identification, and functional network modeling of PTMs.

    “Given the complexity and low abundance of many PTMs, AI-based analytical methods are increasingly used for enrichment, site identification, and functional network modeling139,169,178,179.”

    From Artificial intelligence-driven multi-omics approaches in Alzheimer's disease: Progress, challenges, and future directions (2025) · cites this paper as [169]

    The Clustering and Network analysis section describes a Joint Random Forest method used to identify network modules, supporting the network-modeling part of the claim. The Proteogenomic analysis of TCGA samples section instead describes experimental phosphopeptide enrichment and mass-spectrometry identification of phosphosites; it does not attribute those steps to AI-based methods. The paper also does not establish that use of such methods is increasing (page numbers unavailable in our copy). (LLM, conf=0.85)

  • HR-MS platforms quantify thousands of proteins across a wide dynamic range.

    “These tools quantify thousands of proteins across a wide dynamic range168,169.”

    From Artificial intelligence-driven multi-omics approaches in Alzheimer's disease: Progress, challenges, and future directions (2025) · cites this paper as [169]

    The ‘Proteogenomic analysis of TCGA samples’ section reports that high-resolution mass spectrometry quantified relative abundances for 12,553 proteins across breast tumors, supporting the ‘thousands of proteins’ part. Our copy does not establish that the measurements spanned a wide dynamic range. (LLM, conf=0.84)

  • Modern mass spectrometry can profile more than 12,000 proteins (>10,000 genes) from mammalian tissue samples.

    “MS can profile more than 12,000 proteins (> 10,000 genes) from mammalian tissue samples [16–18].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
