Thyroid Hormone Activates Fibroblast Growth Factor Receptor-1 in Bone
Open accessAbstract
Thyroid hormone (T3) and the T3 receptor (TR) alpha gene are essential for bone development whereas adult hyperthyroidism increases the risk of osteoporotic fracture. We isolated fibroblast growth factor receptor-1 (FGFR1) as a T3-target gene in osteoblasts by subtraction hybridization. FGFR1 mRNA was induced 2- to 3-fold in osteoblasts treated with T3 for 6-48 h, and FGFR1 protein was stimulated 2- to 4-fold. Induction of FGFR1 was independent of mRNA half-life and abolished by actinomycin D and cycloheximide, indicating the involvement of an intermediary protein. Fibroblast growth factor 2 (FGF2) stimulated MAPK in osteoblasts, and pretreatment with T3 for 6 h induced a more rapid response to FGF that was increased in magnitude by 2- to 3-fold. Similarly, T3 enhanced FGF2-activated autophosphorylation of FGFR1, but did not modify FGF2-induced phosphorylation of the docking protein FRS2. These effects were abolished by the FGFR-selective inhibitors PD166866 and PD161570. In situ hybridization analyses of TRalpha-knockout mice, which have impaired ossification and skeletal mineralization, revealed reduced FGFR1 mRNA expression in osteoblasts and osteocytes, whereas T3 failed to stimulate FGFR1 mRNA or enhance FGF2-activated MAPK signaling in TRalpha-null osteoblasts. These findings implicate FGFR1 signaling in T3-dependent bone development and the pathogenesis of skeletal disorders resulting from thyroid disease.

In the citing paper
“Although the thyroid hormone T3 modulates FGFR1 signaling [18,19,20], no explicit genotype-phenotype correlation links this variant to thyroid dysfunction.”

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.
