Targeting and transport: How microtubules control focal adhesion dynamics

Open access
Stehbens, Samantha, Wittmann, Torsten·2012·Journal of Cell Biology

Abstract

Directional cell migration requires force generation that relies on the coordinated remodeling of interactions with the extracellular matrix (ECM), which is mediated by integrin-based focal adhesions (FAs). Normal FA turnover requires dynamic microtubules, and three members of the diverse group of microtubule plus-end-tracking proteins are principally involved in mediating microtubule interactions with FAs. Microtubules also alter the assembly state of FAs by modulating Rho GTPase signaling, and recent evidence suggests that microtubule-mediated clathrin-dependent and -independent endocytosis regulates FA dynamics. In addition, FA-associated microtubules may provide a polarized microtubule track for localized secretion of matrix metalloproteases (MMPs). Thus, different aspects of the molecular mechanisms by which microtubules control FA turnover in migrating cells are beginning to emerge.

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

  • Local stabilization and expansion of microtubules near focal adhesions can potentially trigger GEF-H1 release and RhoA-dependent focal adhesion disassembly during cell movement.

    “Furthermore, local stabilization and expansion of microtubules in the vicinity of focal adhesions 32,74 can potentially trigger GEF-H1 release and RhoA-dependent focal adhesion disassembly during cell movement.”

    From Taxane-induced conformational changes in the microtubule lattice activate GEF-H1-dependent RhoA signalling (2026) · cites this paper as [74]

    In “Microtubules modulate Rho GTPase signaling,” the paper says growing microtubules would be expected to sequester GEF-H1, decreasing rather than triggering RhoA activity; it also says a direct link between GEF-H1 and local microtubule-induced focal adhesion disassembly has not been established. In “Microtubule-mediated transport from and to FAs,” it reports that disassembly induced by microtubule regrowth is independent of RhoA activity. (LLM, conf=0.88)

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.
