Sclerostin

Sclerostin is a protein produced by certain bone cells that regulates bone formation. It acts as an inhibitor, meaning it slows down the activity of cells responsible for building new bone. When sclerostin levels are high, bone growth decreases, which can lead to weaker bones. In contrast, lower levels of sclerostin promote bone formation, making them stronger. Researchers are studying sclerostin because it plays a crucial role in conditions like osteoporosis, where bones become fragile. Understanding this protein could lead to new treatments to improve bone health and prevent fractures.
