Sclerostin, a Wnt signaling antagonist encoded by the SOST gene, negatively regulates osteoblasts and inhibits bone formation. Mechanical loading, which induces bone formation, leads to a decrease in sclerostin levels. Recently, neutralizing antibodies against sclerostin were tested successfully for the treatment of osteoporosis in rodents. However, sclerostin is not the only signal involved in mechanotransduction. Therefore we investigated whether treatment with sclerostin an...

Children with osteogenesis imperfecta (OI) still suffer from frequent fractures, despite bisphosphonate treatment. Thus new therapeutic approaches are needed. Sclerostin is a protein that is thought to inhibit bone formation. Treatment with sclerostin antibodies (SclAB) increases bone mass in animal models and in clinical trials and may be a rational therapy for OI as well.Transgenic (TgOI) Col1a1Jrt/+ mice were gene...

Introduction: Bisphosphonate treatment in children with osteogenesis imperfecta reduces bone catabolism and relies on modelling to form new bone. An anabolic treatment, anti-sclerostin antibody (Anti-SOST Ab), is being investigated in clinical trials. We hypothesized that combined treatment may produce superior outcomes in OI.Methods: Female Col1a2 G610C mice and their wild type littermates (WT) were treated from week 5 to week 9 of life with either sali...

Multiple myeloma is characterized by extensive bone marrow tumour and destructive osteolytic lesions. Both increased bone resorption and suppressed bone formation result in lesions and pathological fractures. Anti-resorptive therapies prevent further bone loss but patients continue to fracture, arguing for new therapies which increase bone strength. Anti-Sclerostin (Anti-Scl) is a potent stimulator of bone formation, is currently in clinical trials for osteoporosis, however it...
