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.

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). However, whether this increase in sclerostin serum levels in patients with chronic kidney disease is attributable to increased production or decreased renal elimination of sclerostin is unknown.

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. In a small Turkish family with sclerosteosis, we identified a missense mutation (c.499T>C; p.Cys167Arg) in exon 2 of the SOST gene.
2014-12-02 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. In addition, we review data from Phase I and II studies of the two humanized Function.
The main function of sclerostin is to stop (inhibit) bone formation. The maintenance of bone over time requires a balance between the formation of new bone tissue and the breakdown and removal (resorption) of old bone tissue. Inhibition of bone formation is necessary to ensure that bones are of the correct shape, size, and density.

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 .Samtida poeter
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.
