Protective effect of caffeic acid phenethyl ester (CAPE) on fluoride-induced oxidative stress and apoptosis in rat endometrium
High fluoride intake may affect biological systems by increasing free radicals, which may enhance lipid peroxidation levels of the tissues, thus leading to oxidative damage. Caffeic acid phenethyl ester (CAPE), a component of honeybee propolis, protects tissues from reactive oxygen species mediated oxidative stress in ischemia-reperfusion and toxic injuries. Several
Exocyclic DNA adducts in sheep with skeletal fluorosis resident in the proximity to the Portoscuso-Portovesme industrial estate on Sardinia Island, Italy
The mechanisms by which fluoride produces its toxic effects are still not clear. Therefore, we conducted a cross-sectional study to evaluate the fluoride-induced toxicity on randomly selected sheep with skeletal fluorosis resident near the large non-ferrous metallurgy Portoscuso-Portovesme industrial estate and the Carbonia and Gonnessa towns (control district) in respect
Simultaneous administration of fluoride and selenite regulates proliferation and apoptosis in murine osteoblast-like MC3T3-E1 cells by altering osteoprotegerin.
The receptor activator nuclear factor kappa-B ligand (RANKL) and its decoy receptor, osteoprotegerin (OPG), are important for maintaining the balance between bone formation and resorption. However, the regulation of microelements on these factors remains unclear. In this study, we used murine osteoblast-like MC3T3-E1 cells to examine the impact of sodium
Fluorosis caused cellular apoptosis and oxidative stress of rat kidneys
As the strongest electronegative element, fluorine can stimulate the production of superoxide radicals in cells. In view of the important roles of kidneys in bone metabolism, the authors analyzed the quantitative pathomorphological characteristics of renal damage and the potential cellular apoptosis and oxidative stress mechanisms in rats treated with excessive
Apoptotic cell death following exposure to fluoride in rat alveolar macrophages.
Since inhaled fluoride is implicated in the acute respiratory failure, cytotoxic effects of fluoride on alveolar macrophages, primary target cells of inhaled toxicants, were investigated. The LC50 of sodium fluoride was estimated to be 0.41 mM, while 1 mM sodium chloride, bromide and iodide had virtually no effects on the
