Pain in fibrous dysplasia: identifying nociceptive mechanisms in a preclinical model.

ABSTRACT: Pain is a common symptom of fibrous dysplasia (FD), a rare mosaic disorder characterized by fibro-osseous lesions in the bone. Despite the prevalence of pain in FD patients, there is little knowledge about the nociceptive mechanisms and few efficacious treatments. As such, understanding FD pain is essential for patient care. The overall aim of this study was to identify nocifensive behaviors and potential underlying mechanisms in a transgenic mouse model of FD, previously shown to display high face and translational validity. Significant nocifensive behaviors were observed in FD mice (male and female), compared to control mice in the burrowing, grid hanging, home cage activity, and wheel running assays. These changes corresponded to lesion development, as visualized by X-ray imaging. Behav
