Vitamin C Attenuates Sodium Fluoride-Induced Mitochondrial Oxidative Stress and Apoptosis via Sirt1-SOD2 Pathway in F9 Cells.
Abstract Increasing evidence has suggested an important role played by reactive oxygen species (ROS) in the pathogenesis of fluorosis. Accumulating evidence demonstrates that vitamin C administration ameliorate sodium fluoride (NaF)-induced oxidative stress. However, the potentially beneficial effects of vitamin C against NaF-induced cytotoxicity and the underlying molecular mechanisms of this protection are not fully understood. Here, we found that NaF stimulated cytotoxicity, increased mitochondrial reactive oxygen species (mROS) production, and induced apoptosis in F9 embryonic carcinoma cells. Consistent with ...

Analysis of the Role of Insulin Signaling in Bone Turnover Induced by Fluoride.
In conclusion, insulin played the important role in bone lesion induced by excessive amount of fluoride through mediating InR receptor signaling, and IGF1 signaling probably exerted action on bone turnover caused by overdose of fluoride. PMID: 26521058 [PubMed - as supplied by publisher]

Effect of siRNA PERK on Fluoride-Induced Osteoblastic Differentiation in OS732 Cells.
This study proved that the mechanism underlying fluoride induced osteoblastic and osteoclastic differentiation possible was due to activation of ALP and RANKL mediated by PERK in OS732 cells. PMID: 24838929 [PubMed - as supplied by publisher]
