Abstract

The Hedgehog (Hh) pathway has become an important model to study the cell biology of primary cilia, and reciprocally, the study of ciliary processes provides an opportunity to solve longstanding mysteries in the mechanism of vertebrate Hh signal transduction. The cilium is emerging as an unique compartment for G-protein-coupled receptor (GPCR) signaling in many systems. Two members of the GPCR family, Smoothened and Gpr161, play important roles in the Hh pathway. We review the current understanding of how these proteins may function to regulate Hh signaling and also highlight some of the critical unanswered questions being tackled by the field. Uncovering GPCR-regulated mechanisms important in Hh signaling may provide therapeutic strategies against the Hh pathway that plays important roles in development, regeneration and cancer.

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

  • Additional HH ligands, desert hedgehog and Indian hedgehog, also operate via primary cilia but in a tissue-specific manner, such as in testis cells and growth plate chondrocytes.

    “Additional ligands of the HH family includes desert (DHH) and Indian (IHH) hedgehog, which also operate via primary cilia but in a tissue-specific manner, such as in cells of the testis and in growth plate chondrocytes 105, respectively.”

    From Cellular signalling by primary cilia in development, organ function and disease (2019) · cites this paper as [105]

    The Introduction (page not available) says vertebrate Hedgehog signaling depends on primary cilia and describes ciliary reception of Hedgehog ligands. It does not identify desert or Indian hedgehog or connect either ligand to testis cells or growth plate chondrocytes; searches for both ligand names found no such passage. (LLM, conf=0.84)

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.
