Sclerostin function

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, 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. 2020-12-19 · sclerostin.

Antagonizing its function is a potential therapeutic strategy to increase high quality bone. Our studies will allow an atomic-level understanding of the interface between sclerostin and three protein partners that mediate sclerostin function. complete loss of function of sclerostin and thus to the characteristic sclerosteosis phenotype. ©2010 Wiley-Liss, Inc. KEY WORDS: SOST, sclerostin, Wnt signaling, sclerosteosis INTRODUCTION Bone mineral density (BMD) in humans is a quantitative trait determined to a great extent by genetic factors 2018-06-07 · In summary, Dkk1 antibody is potently anabolic when sclerostin protein function is disabled by neutralizing antibody, supporting our previous observations that the skeletal efficacy of Dkk1 inhibition can be unlocked if the compensatory effects of sclerostin upregulation are countered. 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.

Sclerostin, the product of the SOST gene, is a secreted inhibitor of Wnt signaling that is produced by osteocytes to regulate bone formation. While it is often considered an osteocyte-specific protein, SOST expression has been reported in numerous other cell types, including hypertrophic chondrocytes and cementocytes. Function i Negative regulator of bone growth that acts through inhibition of Wnt signaling and bone formation.

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.
