The effect of antiresorptive drugs on implant therapy - MUEP

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 p … It is now clear that sclerostin is capable of uncoupling bone formation and bone resorption, by inhibiting osteoblast function while stimulating osteoclast function, as the bone gain achieved by pharmacologic inhibition of sclerostin results from stimulation of osteoblast activity and inhibition of bone resorption. Sclerostin is a key molecular coordinator of both bone formation and bone resorption. • Sclerostin’s skeletal actions are mediated by binding to LRP4 chaperone and LRP5/6 co-receptors and inhibition of Wnt/βcatenin signaling. • Sost/sclerostin expression is tightly controlled by transcriptional regulation and epigenetic modifications. • Sclerostin is secreted by mature osteocytes embedded in the mineralized matrix and inhibits bone formation at the bone surface by binding to LRP5/6 co-receptors and Sclerostin production by osteocytes is inhibited by parathyroid hormone, mechanical loading and cytokines including prostaglandin E 2, oncostatin M, cardiotrophin-1 and leukemia inhibitory factor. Sclerostin production is increased by calcitonin.

Promising news in the treatment of osteoporosis is that sequestering sclerostin from circulation with antibodies stimulates robust bone formation. Pre-clinical studies on rodents and monkeys have confirmed that treatment 2017-03-01 · It is now clear that sclerostin is capable of uncoupling bone formation and bone resorption, by inhibiting osteoblast function while stimulating osteoclast function, as the bone gain achieved by pharmacologic inhibition of sclerostin results from stimulation of osteoblast activity and inhibition of bone resorption. In this review, we highlight the current knowledge on the regulation of Sost/sclerotin expression and its mechanism(s) of action, discuss novel observations regarding its role in signaling pathways activated by hormones and mechanical stimuli in bone, and propose future research needed to understand the full potential of therapeutic interventions that modulate Sost/sclerostin expression. It is now clear that sclerostin is capable of uncoupling bone formation and bone resorption, by inhibiting osteoblast function while stimulating osteoclast function, as the bone gain achieved by pharmacologic inhibition of sclerostin results from stimulation of osteoblast activity and inhibition of bone resorption. 2018-05-05 · Sclerostin stimulates RANKL secretion from osteocytes which in turn activates osteoclast and thus induces bone resorption. Sclerostin secretion is inhibited by PTH (parathyroid hormone), TGF-β (transforming growth factor – β), prostaglandin E2 (PGE2) and E2. Romosozumab, a sclerostin inhibitor that is the first agent in its class approved for osteoporosis treatment in postmenopausal women, has a unique mechanism of action that promotes bone formation while decreasing bone resorption. Sclerostin is one key Wnt pathway regulator.

2013-11-29 · As other studies have also shown that Sclerostin can inhibit Wnt3a in vitro , , , we have to accept that Sclerostin is (at least from a mechanistic point of view) a Wnt3a inhibitor even though Sclerostin and Wnt3a do not exhibit overlapping binding sites on LRP6 , and thus the inhibition cannot be explained by a pure competition mechanism.

In contrast to previous reports Sclerostin is a direct modulator/inhibitor of the Wnt signaling pathway and not an antagonist of … Sclerostin Sclerostin which is a potent inhibitor of osteoblastogenesis is a glycoprotein secreted by osteocytes. Sclerostin after secretion by osteocytes travels through osteocyte canaliculi to the bone surface where it binds to coreceptors LRP5 and LRP6 thus preventing colocalization with frizzled protein and Wnt signaling, and thereby reducing osteoblastogenesis and bone formation [3].
