Regulation of the Bioavailability of TGF-β and TGF-β-Related Proteins

Abstract

The bioavailability of members of the transforming growth factor β (TGF-β) family is controlled by a number of mechanisms. Bona fide TGF-β is sequestered into the matrix in a latent state and must be activated before it can bind to its receptors. Here, we review the molecules and mechanisms that regulate the bioavailability of TGF-β and compare these mechanisms with those used to regulate other TGF-β family members. We also assess the physiological significance of various latent TGF-β activators, as well as other extracellular modulators of TGF-β family signaling, by examining the available in vivo data from knockout mouse models and other biological systems.

  • CAFs support tumor growth and progression via secreted or membrane-associated signals and ECM deposition, which stores TGF-β.

    “CAFs support tumor growth and progression through secreted or membrane-associated signals that benefit the carcinoma cells, and deposition of extracellular matrix (ECM) proteins, which confer instructive signals, and retain and thus store secreted chemokines and cytokines, including TGF-β40,43.”

  • Latent TGF-β1 complexes are deposited in ECM via LTBP1 and require activation to release mature TGF-β that can bind receptors locally.

    “Latent complexes of the TGF-β1 homodimer, often have one of the dimeric pro-segments covalently linked to a fibrillin-like latent TGF-β binding protein 1 (LTBP1) that enables their deposition in the ECM43 (Figure 2B). Secretion of such complexes does not result in release of soluble active TGF-β, but in localized deposition of inactive complexes in proximity to TGF-β expressing cells. As a con”

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.
