Adults affected with XLH develop a mineralization of the bone-tendon attachment site (enthesis), called enthesopathy, which causes significant pain and impaired movement. Entheses in mice with XLH (Hyp) have enhanced bone morphogenetic protein (BMP) and Indian hedgehog (IHH) signaling. Treatment of Hyp mice with the BMP signaling blocker palovarotene attenuated BMP\/IHH signaling in Hyp entheses, thus indicating that BMP signaling plays a pathogenic role in enthesopathy development and that IHH signaling is activated by BMP signaling in entheses. It was previously shown that mRNA expression of growth\/differentiation factor 5 (Gdf5) is enhanced in Hyp entheses at P14. Thus, to determine a role for GDF5 in enthesopathy development, Gdf5 was deleted globally in Hyp mice and conditionally in Scx\u2009+\u2009cells of Hyp mice. In both murine models, BMP\/IHH signaling was similarly decreased in Hyp entheses, leading to decreased enthesopathy. BMP\/IHH signaling remained unaffected in WT entheses with decreased Gdf5 expression. Moreover, deletion of Gdf5 in Hyp entheses starting at P30, after enthesopathy has developed, partially reversed enthesopathy. Taken together, these results demonstrate that while GDF5 is not essential for modulating BMP\/IHH signaling in WT entheses, inappropriate GDF5 activity in Scx\u2009+\u2009cells contributes to XLH enthesopathy development. As such, inhibition of GDF5 signaling may be beneficial for the treatment of XLH enthesopathy.<\/jats:p>","DOI":"10.1093\/jbmr\/zjae086","type":"journal-article","created":{"date-parts":[[2024,6,5]],"date-time":"2024-06-05T17:35:24Z","timestamp":1717608924000},"source":"Crossref","is-referenced-by-count":1,"title":["The
