Sclerostin anibody treatment enhanced metaphyseal bone healing

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. Objective. Sclerostin is a Wnt inhibitor produced specifically by osteocytes.

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. Although it is well is crucial to mediate the inhibitory function of sclerostin on Wnt1/ -catenin signaling and on bone formation. Moreover, we describe the identification of LRP4 mutations, which are 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).

More recently, sclerostin has been identified as binding to LRP5 / 6 receptors and inhibiting the Wnt signaling pathway. After discovering that lack of Sost/sclerostin expression is the cause of the high bone mass human syndromes Van Buchem disease and sclerosteosis, extensive animal experimentation and clinical studies demonstrated that sclerostin plays a critical role in bone homeostasis and that its deficiency or pharmacological neutralization increases bone formation.

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 ). 2020-11-18 Sclerosteosis-1 (SOST1: MIM 269500) is linked to a genetic defect in the SOST gene coding for sclerostin. 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 [ 2 2011-06-03 Genetic and phenotypic analysis of the extremely rare high bone mass disease, sclerosteosis, led to the discovery of the protein sclerostin and defined its function as a key negative regulator of bone mass and bone formation. 3-7 Sclerostin, encoded by the SOST gene, is a secreted, cystine‐knot glycoprotein expressed primarily in bone, specifically by osteocytes. 8-10 In humans with 2011-12-01 2020-05-26 Sclerostin might function as a BMP inhibitor, reducing the differentiation of osteoprogenitor cells and promoting osteoblast apoptosis . However, since sclerostin was subsequently shown not to inhibit early BMP‐induced responses in vitro, it was suggested that it might act by modulating Wnt signaling .

Sclerostin (gene name Sost) is a secreted 27 kDa glycoprotein that inhibits the differentiation and activity of bone-forming osteoblasts by antagonizing the Wnt/β-catenin signaling pathway (Baron and Gori, 2018; Drake and Khosla, 2017). 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.
