Thyrotoxicosis is characterised by increased osteoclast activity. Thyroid hormone receptor alpha (TRα) is the predominant TR-isoform in bone and mice lacking TRα have skeletal hypothyroidism with impaired osteoclastic bone resorption. By contrast, mice lacking TRβ have skeletal hyperthyroidism and increased bone resorption. Thus, we hypothesized that T3 acts via TRα to stimulate osteoclastogenesis. Osteoclasts were differentiated in vitro ...
