Fibroblast-led collective invasion of carcinoma cells with differing roles for RhoGTPases in leading and following cells

Abstract

Imaging of collectively invading cocultures of carcinoma cells and stromal fibroblasts reveals that the leading cell is always a fibroblast and that carcinoma cells move within tracks in the extracellular matrix behind the fibroblast. The generation of these tracks by fibroblasts is sufficient to enable the collective invasion of the squamous cell carcinoma (SCC) cells and requires both protease- and force-mediated matrix remodelling. Force-mediated matrix remodelling depends on integrins alpha3 and alpha5, and Rho-mediated regulation of myosin light chain (MLC) activity in fibroblasts, but these factors are not required in carcinoma cells. Instead, carcinoma cells use Cdc42 and MRCK (myotonic dystrophy kinase-related CDC42-binding protein kinases) mediated regulation of MLC to follow the tracks generated by fibroblasts.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • CAFs are key contributors to ECM remodeling, angiogenesis, and metastasis.

    “These CAFs are characterized by the expression of specific markers, such as desmin and fibroblast activation protein, and are now recognized as key contributors to ECM remodeling, angiogenesis, and metastasis [36,37,38,39,40].”
  • CAF ECM deposition and remodelling depends on RHO and RAB GTPase-mediated control of integrin-mediated adhesions and the actomyosin cytoskeleton and is linked to downregulation of CD36.

    “This depends on RHO and RAB GTPase-mediated control of integrin-mediated adhesions and the actomyosin cytoskeleton81–83 and is linked to downregulation of the transmembrane receptor CD36 (also known as platelet glycoprotein 4)84.”
  • Production of matrix proteases allows the tumour matrix to be remodelled, which can lead to generation of permissive tracks that allow cancer cell invasion.

    “Although chemical crosslinks are not readily reversed, the production of matrix proteases allows the tumour matrix to be remodelled, and this can lead to the generation of permissive tracks that allow cancer cell invasion81.”
  • CAFs secrete growth factors, proinflammatory cytokines, and chemokines, particularly TGF-β, IL-6, and CCL2, which recruit immunosuppressive cells into the tumor stroma and lead to immune escape.

    “In addition, CAFs secrete substantial amounts of growth factors, proinflammatory cytokines, and chemokines, particularly TGF-β, IL-6, and CC-chemokine ligand 2, which recruit immunosuppressive cells into the tumor stroma and lead to immune escape 20-22.”

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.
