Abstract

Accelerated osteoclastic bone resorption has a central role in the pathogenesis of osteoporosis and other bone diseases. Identifying the molecular pathways that regulate osteoclast activity provides a key to understanding the causes of these diseases and to the development of new treatments. Here we show that mice with inactivation of cannabinoid type 1 (CB1) receptors have increased bone mass and are protected from ovariectomy-induced bone loss. Pharmacological antagonists of CB1 and CB2 receptors prevented ovariectomy-induced bone loss in vivo and caused osteoclast inhibition in vitro by promoting osteoclast apoptosis and inhibiting production of several osteoclast survival factors. These studies show that the CB1 receptor has a role in the regulation of bone mass and ovariectomy-induced bone loss and that CB1- and CB2-selective cannabinoid receptor antagonists are a new class of osteoclast inhibitors that may be of value in the treatment of osteoporosis and other bone diseases.

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

  • Increased β-adrenergic activity can reduce bone mass.

    “Increased β-adrenergic activity can decrease bone mass, but other neural pathways may be involved (104, 105).”

    From Pathogenesis of osteoporosis: concepts, conflicts, and prospects (2005) · cites this paper as [104]

    The Introduction (page unavailable) says neuroendocrine pathways and neurotransmitters regulate bone remodelling, but does not identify β-adrenergic activity. The Results and Discussion (pages unavailable) address cannabinoid receptors and bone mass; searches for β-adrenergic activity and sympathetic signalling found no passage supporting the specific claim.

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.
