We then discuss human disorders of decreased sclerostin function and animal models of sclerostin inhibition. Both have served to elucidate the effects of decreased sclerostin levels and function – increased bone mass and strength and fewer fractures. 2011-10-04 · Sclerostin is a product of mature osteocytes embedded in mineralised bone and is a negative regulator of bone mass and osteoblast differentiation. While evidence suggests that sclerostin has an anti-anabolic role, the possibility also exists that sclerostin has catabolic activity. To test this we treated human primary pre-osteocyte cultures, cells we have found are exquisitely sensitive to View protein in InterPro IPR029034, Cystine-knot_cytokine IPR008835, Sclerostin/SOSTDC1 IPR015665 PANTHER i PTHR14903 , PTHR14903, 1 hit PTHR14903:SF4 , PTHR14903:SF4, Sclerostin antibodies in osteoporosis: latest evidence and therapeutic potential Michael R. McClung Abstract: Sclerostin is an osteocyte-derived glycoprotein that inhibits Wnt/β-catenin signaling and activation of osteoblast function, thereby inhibiting bone formation. It plays a vital role in the regulation of skeletal growth. Kusu et al.

Sclerostin function

The disease is thought to be due to loss‐of‐function mutations in the SOST gene. The SOST gene product, sclerostin, is secreted by osteocytes and transported to the bone surface where it inhibits osteoblastic bone formation by antagonizing Wnt signaling. Sclerostin‐transgenic mice are osteopenic. We evaluated the function of sclerostin in an in vivo model by overexpressing human sclerostin in mice. Sclerostin‐transgenic mice were generated by selectively targeting the expression of human SOST to bone with the mouse osteocalcin promoter, OG2 (Desbois et al., 1994). Sclerostin is a secreted extracellular matrix protein that is expressed at low levels in bone, bone marrow and cartilage. It may also be detected in other tissues such as kidney and liver.

Sclerostin, the product of the SOST gene, is a secreted inhibitor of Wnt signaling that is produced by osteocytes to regulate bone formation.

Induced sclerostin Scientific findings.

Function. Sclerostin, the product of the SOST gene, located on chromosome 17q12–q21 in humans, was originally believed to be a non-classical bone morphogenetic protein (BMP) antagonist. More recently, sclerostin has been identified as binding to LRP5 / 6 receptors and inhibiting the Wnt signaling pathway.

In a small Turkish family with sclerosteosis, we identified a missense mutation (c.499T>C; p.Cys167Arg) in exon 2 of the SOST gene.

NX_Q9BQB4 - SOST - Sclerostin - Function. Negative regulator of bone growth that acts through inhibition of Wnt signaling and bone formation. Humans lacking sclerostin display progressive bone over-growth due to increased bone formation.

Genetic deletion of the Sost gene in mice results in extraordinarily high bone mass (Li et al., 2008). Sclerostin is a Wnt signaling pathway antagonist that results in negative regulation of bone formation by repressing differentiation and proliferation of osteoblasts (3, 4). It also promotes osteoblast apoptosis. Increased sclerostin action is thought to be involved in osteoporosis. Those data implied that sclerostin played an essential role in mediating bone response to mechanical unloading, likely through Wnt/β‐catenin signaling. Our findings also indicated sclerostin is a promising target for preventing disuse osteoporosis.

Supporting the importance of sclerostin in the kidney, though, a meta-analysis of genomewide association studies found robust association between SNPs in B4GALNT3 , which is highly expressed in the kidney, and serum sclerostin ( 93 ). Sclerostin Function. Sclerostin is nearly exclusively produced in osteocytes (van Bezooijen et al., 2009). Mutations in the Sclerostin (SOST) gene can cause sclerosteosis and van Buchem disease which are bone dysplasia disorders characterized by progressive skeletal overgrowth (Wergedal et al., 2003).
