The effects of sclerostin antibody plus parathyroid hormone (1–34) on bone formation in ovariectomized rats

Abstract: Previous studies have demonstrated the effects of sclerostin antibody (Scl-Ab) and parathyroid hormone (1-34, PTH) on healing in osteoporosis; however, reports about the combined effects of Scl-Ab plus PTH on osteoporosis are limited. This study was designed to investigate the impact of combined treatment with Scl-Ab and PTH on osteoporosis healing in ovariectomized (OVX) rats. After bilateral ovariectomy, 12 weeks were allowed to pass for the establishment of standard conditions for osteoporosis in animal mod… Show more

“…In contrast to Scl-Ab, hPTH substantially increases both bone anabolic (formation) and catabolic (resorption) activities, although the former is more pronounced during the first few months of therapy in humans. hPTH stimulates osteogenesis in PTH1R + osteoprogenitors [18] and increases the activity of mature osteoblasts, resulting in increased bone formation and bone mass [1,2,19]. This activation may be in part due to enhanced Wnt signaling, but other pathways are certainly operative [18,20].…”

“…In four studies [ 33 , 35 , 58 , 59 ], ovariectomy surgery was performed to induce osteopenia. In the initial sample size, 223 ovariectomized (OVX) and 153 sham-ovariectomized (Sham) rats were identified.…”

“…SOSTi (Romosozumab) is a humanized monoclonal antibody that binds sclerostin, preventing binding to LRP5/6 and increasing Wnt pathway activation and bone formation (43). It is FDA-approved for the treatment of osteoporosis (20,44) and has activity in rodents in addition to humans (45,46).…”
