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. Sclerostin is secreted by the bone resident cell (osteocytes) and inhibits bone formation by inhibiting osteoblast differentiation. Sclerostin deficiency is a cause of sclerostosis (very high bone mineral density) [24]. Sclerostin is different than other markers of bone resorption or formation because it is not just a marker but thought to be part of the actual pathologic process in some cases. Sclerostin, the product of the SOST gene, is a secreted inhibitor of Wnt signaling that is produced by osteocytes to regulate bone formation.

Sclerostin function

Objective. Sclerostin is a Wnt inhibitor produced specifically by osteocytes. However, it is not currently clear whether renal dysfunction has an effect on circulating sclerostin level in patients with type 2 diabetes. The aim of the study was to evaluate this relationship. Design and Patients.

It also promotes osteoblast apoptosis. Increased sclerostin action is thought to be involved in osteoporosis. Sclerostin is produced in osteocytes, which are a type of bone cell. 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.

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. While it is often considered an osteocyte-specific protein, SOST expression has been reported in numerous other cell types, including hypertrophic chondrocytes and cementocytes. In addition, sclerostin appears to have more than one binding partner and is likely to function by interacting with multiprotein signaling complexes, making research in this area experimentally challenging.

Inactivating mutations of the SOST gene lead to exuberant bone growth, as demonstrated in the human disorders sclerosteosis and van Buchem's disease ( 6 – 9 ). NX_Q9BQB4 - SOST - Sclerostin - Function. Negative regulator of bone growth that acts through inhibition of Wnt signaling and bone formation. Sclerostin is a Wnt signaling pathway antagonist that results in negative regulation of bone formation by repressing differentiation and proliferation of osteoblasts (3, 4).

Sclerostin‐transgenic mice are osteopenic. We evaluated the function of sclerostin in an in vivo model by overexpressing human sclerostin in mice. 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 SOST gene product that reduces osteoblastic bone formation by inhibiting canonical Wnt/β-catenin signaling.

While it is often considered an osteocyte-specific protein, SOST expression has been reported in numerous other cell types, including hypertrophic chondrocytes and cementocytes.
