Sclerostin is a glycoprotein encoded by the SOST gene and produced in osteocytes.49–51 Mutant SOST genes have been identified in the condition sclerosteosis, which is characterized by progressive thickening of bone.52,53 Sclerostin is an inhibitor of the Wnt/β-catenin signaling pathway, which stimulates osteoblast differentiation and The SOST gene, which encodes sclerostin, a member of Dan family glycoproteins, was originally identified as the gene responsible for two sclerosing bone dysplasias, sclerosteosis and … Sclerostin, a product of the SOST gene primarily expressed by osteocytes, is a secreted glycoprotein that functions as a key negative regulator of bone formation. 88,89 In humans, reduced sclerostin concentration and/or activity leads to two genetic diseases known as … Thus, sclerostin has quickly become a promising molecular target for the treatment of osteoporosis and other skeletal diseases, and beneficial skeletal outcomes are observed in animal studies and clinical trials using neutralizing antibodies against sclerostin. As already mentioned above, in the bone, sclerostin is mainly produced by the osteocytes, the cells that reside within the bone matrix and comprise between 90%–95% of all bone cells. After its secretion, sclerostin will be anchored to the LRP4 receptor on the osteoblast membrane, by which sclerostin is retained in the bone compartment [20]. The first report of pharmacologic inhibition of sclerostin described the effects of sclerostin antibody (Scl‐Ab) administration in aged ovariectomized (OVX) rats, a widely used model for postmenopausal osteoporosis. 44 In this study, short‐term treatment with Scl‐Ab not only resulted in complete reversal of the 1 year of estrogen‐deficiency‐induced bone loss but also further increased bone mass and bone … 2012-01-20 2020-09-25 2011-10-04 Summary: Sclerostin is a secreted glycoprotein with a C-terminal cysteine knot-like (CTCK) domain and sequence similarity to the DAN (differential screening-selected gene aberrative in neuroblastoma) family of bone morphogenetic protein (BMP) antagonists. Sclerostin is a central intracellular signaling protein with the ultimate effect of inhibiting osteoblastic bone formation.

Sclerostin is a member of the DAN family of glycoproteins . These proteins have been reported to antagonize bone morphogenetic protein (BMP) activity and to consequently inhibit bone formation.

Sclerostin is a secreted glycoprotein with a C-terminal cysteine knot -like (CTCK) domain and sequence similarity to the DAN (differential screening-selected gene aberrative in neuroblastoma) family of bone morphogenetic protein (BMP) antagonists. Sclerostin is a Wnt inhibitor, produced by osteocytes which inhibits osteoblast-induced bone formation (Moester et al., 2010). The production of sclerostin is upregulated by glucocorticoids, while intermittent parathyroid hormone (PTH) inhibits the production by osteocytes. The SOST gene, which encodes sclerostin, a member of Dan family glycoproteins, was originally identified as the gene responsible for two sclerosing bone dysplasias, sclerosteosis and van Buchem disease.
