Suppression of Sclerostin and Dickkopf-1 levels in patients with fluorine bone injury

Evidence has been accumulating for the role of Sclerostin and Dickkopf-1 as the antagonists of Wnt/β-Catenin signaling pathway, which suppresses bone formation through inhibiting osteoblastic function. To get deep-inside information about the expression of the antagonists in patients with fluorine bone injury, a case-control study was conducted in two counties in Hubei Province. Urinary and serum fluoride were significantly higher in patients with fluorine bone injury than in healthy controls. Additionally, patients with fluorine bone injury had significantly lower serum Sclerostin and Dickkopf-1 levels compared with healthy controls (P
