Abstract

The extracellular matrix (ECM) is a complex meshwork of cross-linked proteins providing both biophysical and biochemical cues that are important regulators of cell proliferation, survival, differentiation, and migration. We present here a proteomic strategy developed to characterize the in vivo ECM composition of normal tissues and tumors using enrichment of protein extracts for ECM components and subsequent analysis by mass spectrometry. In parallel, we have developed a bioinformatic approach to predict the in silico "matrisome" defined as the ensemble of ECM proteins and associated factors. We report the characterization of the extracellular matrices of murine lung and colon, each comprising more than 100 ECM proteins and each presenting a characteristic signature. Moreover, using human tumor xenografts in mice, we show that both tumor cells and stromal cells contribute to the production of the tumor matrix and that tumors of differing metastatic potential differ in both the tumor- and the stroma-derived ECM components. The strategy we describe and illustrate here can be broadly applied and, to facilitate application of these methods by others, we provide resources including laboratory protocols, inventories of ECM domains and proteins, and instructions for bioinformatically deriving the human and mouse matrisome.

  • Hynes and Naba first presented the matrisomics concept in 2012, establishing a matrisome database that classifies ECM into core matrisome proteins (collagens, proteoglycans, and glycoproteins) and matrisome-associated proteins (secreted factors, regulators, and ECM-affiliated proteins), providing a reliable reference for comprehensive dECM analysis.

  • TSC2−/− astrocytes show high expression of extracellular matrix synthesis and remodelling genes including COL3A1, MMP14, DCN, CD44 and TIMP2.

    “In addition, we observed high expression of several genes associated with extracellular matrix synthesis and remodelling, including COL3A1, MMP14, DCN, CD44 and TIMP237 (Fig. 2m, Extended Data Fig. 2b,d and Supplementary Table 8).”

    The Results (page unavailable) classify collagens and proteoglycans as core extracellular-matrix components and matrix metalloproteinases and their regulators as ECM regulators. This supports the cited paper’s role in identifying ECM-related gene categories, but our copy does not explicitly classify all five named genes. The high expression in TSC2−/− astrocytes is presented as the citing authors’ own observation, not a finding attributed to this source. (LLM, conf=0.83)

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.
