Abstract

Previously we observed that capsaicin treatment in rats inhibited sensory neuropeptide signaling, with a concurrent reduction in trabecular bone formation and bone volume, and an increase in osteoclast numbers and bone resorption. Calcitonin gene-related peptide (CGRP) is a neuropeptide richly distributed in sensory neurons innervating the skeleton and we postulated that CGRP signaling regulates bone integrity. In this study we examined CGRP effects on stromal and bone cell differentiation and activity in vitro. CGRP receptors were detected by immunocytochemical staining and real time PCR assays in mouse bone marrow stromal cells (BMSCs) and bone marrow macrophages (BMMs). CGRP effects on BMSC proliferation and osteoblastic differentiation were studied using BrdU incorporation, PCR products, alkaline phosphatase (ALP) activity, and mineralization assays. CGRP effects on BMM osteoclastic differentiation and activity were determined by quantifying tartrate-resistant acid phosphatase positive (TRAP+) multinucleated cells, pit erosion area, mRNA levels of TRAP and cathepsin K, and nuclear factor-κB (NF-κB) nuclear localization. BMSCs, osteoblasts, BMMs, and osteoclasts all expressed CGRP receptors. CGRP (10-10-10-8M) stimulated BMSC proliferation, up-regulated the expression of osteoblastic genes, and increased ALP activity and mineralization in the BMSCs. In BMM cultures CGRP (10-8M) inhibited receptor activator of NF-κB ligand (RANKL) activation of NF-κB. CGRP also down-regulated osteoclastic genes like TRAP and cathepsin K, decreased the numbers of TRAP+ cells, and inhibited bone resorption activity in RANKL stimulated BMMs. These results suggest that CGRP signaling maintains bone mass both by directly stimulating stromal cell osteoblastic differentiation and by inhibiting RANKL induced NF-κB activation, osteoclastogenesis, and bone resorption.

  • CGRP acts with higher potency to inhibit osteoclast activity than osteoclast differentiation.

  • In mouse bone marrow cells induced by M-CSF and RANKL, CGRP reduced resorption pit area at 0.1 nM or higher, whereas 10 nM was required to inhibit TRAP-positive cell formation.

    “In cells cultured from mouse bone marrow and induced to differentiate into osteoclasts by M-CSF and RANKL, the area of resorption pits was reduced by CGRP in a concentration of 0.1 nM or higher, whereas higher concentrations of 10 nM CGRP were required for the inhibition of TRAP-positive cell formation”

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.
