Determinants and correlates of circulating sclerostin Serum sclerostin levels increase along the progression of CKD to reach levels that are two- to fourfold higher in patients with end-stage renal disease as compared with individuals with normal renal function.11,27–32 Sclerostin levels may be with amino acids in the loop2 region of sclerostin. Six compound exhibited interaction with Ile95 and 2 compounds with Asn93, an amino acid in the loop2 region known to be involved in sclerostin’s inhibitory effect, suggesting that the identified compounds have the potential to bind and neutralize sclerostin function. A Novel Loss-of-Sclerostin Function Mutation in a First Egyptian Family with Sclerosteosis Alaaeldin Fayez IntroductionSclerosteosis (SOST1: MIM 269500) is an autosomal recessive sclerosing skeletal dysplasia in which bone overgrowth throughout life, affecting mainly the cranial and tubular bones, leads to distortion of facies and entrapment of cranial nerves. 2011-04-06 · Bone overgrowth-associated mutations in the LRP4 gene impair sclerostin facilitator function.

Activating mutations of the putative Wnt co-receptor Lrp5 or inactivating mutations of the secreted molecule Sclerostin cause excessive bone formation in mice and humans. Previous studies have suggested that Sclerostin functions as an Lrp5 antagonist, yet clear in vivo evidence was still missing, and alternative mechanisms have been discussed. Sclerostin interacts with multiple proteins that alter bone formation and resorption and is likely to function by altering several biologically relevant pathways in bone. These results provide in vivo evidence of increased bone formation caused by the absence or decreased synthesis of sclerostin in humans. Sclerostin is a glycoprotein involved in the regulation of bone metabolism, exclusively secreted by osteocytes. It affects the activity of bone morphogenetic proteins (BMPs) and is an inhibitor of the Wnt/β-catenin met - Sclerostin, the product of the SOST gene, is a secreted inhibitor of Wnt signaling that is produced by osteocytes to regulate bone formation.

eCollection 2017. Similar to sclerostin inactivation in humans, mice with a targeted deletion of the sclerostin gene (SOST knockout mice) were found to have high bone mass, demonstrating evolutionary conservation of sclerostin's function as a negative regulator of bone formation.

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.

Sclerostin, encoded by the Sost gene, is a secreted cysteine‐knot protein among the DAN family, which includes proteins antagonize BMP and Wnt signaling. 11 Sclerostin has emerged as a potent inhibitor of bone growth. 12-15 Sclerostin was originally identified as a BMP antagonist because of its cysteine‐knot domain, which was shared by BMP antagonists, and its binding to BMP and potent inhibition on BMP‐induced osteogenesis, 16, 17 although it did not function as classical BMP Sclerostin is now understood to act as an antagonist of the canonical WNT signalling pathway in osteoblast lineage cells, thereby negatively regulating bone formation. Sclerostin serum levels increase gradually as kidney function declines and are approximately 3–4 times higher in patients with end-stage renal failure compared with healthy controls (9, 10).

Manual assertion based on experiment in i 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 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 ( 9 ).
