In addition to surgery, which is the primary treatment of choice, adjuvant therapy is used to lower the risk of recurrence. However, denosumab, the standard adjuvant treatment currently used, only targets osteoclast-like giant cells and does not affect neoplastic stromal cells. Since some GCTBs are inoperable, or even after surgery, there can be residual tumor cells at the site of the tumor, novel therapies, especially those that target neoplastic stromal cells, are needed. Both cell types in GCTB show altered expression of various specific genes and molecules, and these deregulated molecular profiles could serve as biomarkers and targets for targeted therapy.

Moreover, suppressing remodeling inhibits bone formation in <em>Sost</em>-deficient mice. These latter studies suggest that bone remodeling is required for the full anabolic effect of sclerostin suppression. To address this, we suppressed bone remodeling in mice using the anti-RANKL antibody denosumab and then administered romosozumab, along with continued denosumab. Controls received either vehicle, denosumab alone, or romosozumab alone. The romosozumab-induced increase in bone was not blunted by denosumab. Similarly, the romosozumab-induced increases in osteoblast number and bone formation were not altered by denosumab. The anabolic effect of romosozumab was also not altered in a mouse model of rebound resorption caused by denosumab discontinuation. Nonetheless, denosumab reduced bone formation in Sost-deficient mice. These results demonstrate a striking difference in the dependence on bone remodeling for the anabolic effects of sclerostin suppression versus genetic inactivation of Sost and suggest distinct mechanisms drive osteoblast production in the two conditions. In addition, they suggest that the blunted response to romosozumab in clinical studies is not due to suppressed remodeling.</div></div>","PeriodicalId":9301,"journal":{"name":"Bone","volume":"199 ","pages":"Article 117567"},"PeriodicalIF":3.5,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144313986","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fifty individuals, aged 15.0–17.9 years, with a T1D duration of at least 8 years and (mean ± SD) 10.6 ± 2.1 years were included, hence the participants had diabetes throughout most part of their puberty and growth spurt.

Clinical follow-up data were retrieved from the Swedish National Diabetes Registry. The control group comprised 50 healthy matched adolescents, aged 15.1–17.9 years.
