DESCRIPTION (provided by applicant): The objective of this R21 application is to investigate at the atomic level, the mechanism of action of sclerostin, an osteocyte-derived, secreted, cystine-knot protein that inhibits bone formation by examining how sclerostin interacts with proteins that play an essential role in mediating its activity.

Further, the cellular source of sclerostin in the bone/bone marrow microenvironment under physiological and pathological conditions, the pathways that regulate sclerostin expression and the mechanisms by which sclerostin modulates the activity of osteocytes, osteoblasts, and osteoclasts remain unclear.

Two mechanisms may explain efficacy in serotonin syndrome: (1) Dexmedetomidine stimulates alpha-2C receptors in Sclerostin (SCL/SOST) is almost exclusively produced by osteocytes in steady- state bone(1).

The identity of the cell type responsive to sclerostin, a negative regulator of bone mass, is unknown. Since sclerostin is expressed in vivo by mineral-embedded osteocytes, we tested the hypothesis that sclerostin would regulate the behavior of cells actively involved in mineralization in adult bone, the preosteocyte.

This distinguishes sclerostin's mechanism of action from that of the Wnt antagonist Dkk1. Sclerostin, encoded by the SOST gene and synthesized by osteocytes, is a Wnt antagonist that prevents osteoblast differentiation by suppressing Wnt signaling in osteoblast precursors, thereby reducing bone formation. sclerostin inhibitors in the management of patients with osteoporosis. Sclerostin Deﬁciency Sclerosteosis and van Buchem disease are two rare, auto-somal recessive, sclerosing bone disorders characterized by high bone mass and increased bone strength caused by defects of the SOST gene in chromosome 17q12-21 that encodes sclerostin [7–12].

42, 43 Above and beyond the reported associations with LRP5 and BMPs, hints that sclerostin's mechanism of action at the molecular level might contain additional complexity came from the observation that sclerostin's inhibitory activity was notably variable across different osteoblast‐lineage cell Sclerostin suppression is required for balanced remodeling in response to PTH . Serum sclerostin levels are significantly higher in postmenopausal women than in premenopausal women with significant negative correlations between free estrogen levels and sclerostin as well as PTh and sclerostin . Sclerostin is a negative regulator of bone formation which was discovered through the detection of a mutation in the SOST gene in patients diagnosed with the high bone mass disease, sclerosteosis. 1 Parallel to the human disease, mice with a targeted deletion of SOST demonstrate an extremely high bone mass phenotype, highlighting the conservation of sclerostin's negative regulation of bone To investigate the mechanism of action of dried plum in reversing bone loss, we measured serum levels of RANKL, OPG and sclerostin in osteopenic postmenopausal women (n 160).

It affects the activity of bone morphogenetic proteins (BMPs) and is an inhibitor of the Wnt/β-catenin metabolic pathway in bone cells. Osteocytes reduce the release of sclerostin in response to mechanical stimuli acting on bone, and thus 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.

sclerostin was initially considered to be a BMP an-tagonist.4 Later studies, however, demonstrated that sclerostin’s mechanism of action is different from that of the classical BMP antagonists and is medi-ated through inhibition of Wnt signaling activity.4,26 The Wnt signaling pathway is an evolutionary,

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.
