The role of hedgehog signalling in skeletal health and disease

Alman, Benjamin A.·2015·Nature Reviews Rheumatology

Abstract

Hedgehog ligands bind to protein patched homologue 1 (PTC), a conserved receptor that activates the GLI family of transcription factors, which are involved in development, disease and skeletal repair processes. During embryonic development, hedgehog signalling helps to pattern the limbs and plays a critical part in regulating chondrocyte differentiation and osteogenesis during the longitudinal growth of long bones. This signalling pathway also regulates mesenchymal cell differentiation during skeletal repair and regeneration. In pathologic and degenerative processes, such as osteoarthritis or cartilaginous tumour formation, hedgehog signalling is dysregulated. Several pharmacologic strategies can modulate hedgehog signalling, and targeting this pathway could lead to the development of novel therapeutic approaches. For example, by precisely regulating the level of activity of the hedgehog signalling pathway, the pace of degeneration in osteoarthritis could be slowed, bone repair could be enhanced, and cartilaginous tumour cell viability could be inhibited. As such, regulation of hedgehog signalling could be manipulated to safeguard skeletal health.

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

  • Hedgehog signaling is important for maintaining bone homeostasis in adult mice, with down-regulation of hedgehog signaling being protective against bone loss.

    “In addition to the roles that IHH and SHH play in regulating bone development, hedgehog signaling is also important for maintaining bone homeostasis in adult mice, with down-regulation of hedgehog signaling being protective against bone loss (41, 42).”

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.
