Abstract

Childhood hypothyroidism delays ossification and bone mineralization, whereas adult thyrotoxicosis causes osteoporosis. To determine how effects of thyroid hormone (T3) during development manifest in adult bone, we characterized TRalpha1(+/m)beta(+/-) mice, which express a mutant T3 receptor (TR) alpha1 with dominant-negative properties due to reduced ligand-binding affinity. Remarkably, adult TRalpha1(+/m)beta(+/-) mice had osteosclerosis with increased bone mineralization even though juveniles had delayed ossification. This phenotype was partially normalized by transient T3 treatment of juveniles and fully reversed in compound TRalpha1(+/m)beta(-/-) mutant mice due to 10-fold elevated hormone levels that allow the mutant TRalpha1 to bind T3. By contrast, deletion of TRbeta in TRalpha1(+/+)beta(-/ -) mice, which causes a 3-fold increase of hormone levels, led to osteoporosis in adults but advanced ossification in juveniles. T3-target gene analysis revealed skeletal hypothyroidism in TRalpha1(m/+)beta(+/-) mice, thyrotoxicosis in TRalpha1(+/+)beta(-/-) mice, and euthyroidism in TRalpha1(+/)beta(-/-) double mutants. Thus, TRalpha1 regulates both skeletal development and adult bone maintenance, with euthyroid status during development being essential to establish normal adult bone structure and mineralization.

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.
