Arsenic and fluoride induce apoptosis, inflammation and oxidative stress in cultured human umbilical vein endothelial cells
Excessive amount of inorganic arsenic (iAs) and fluoride (F) coexist in drinking water in many regions, which is associated with high risk of vascular diseases. However, the underlying mechanisms are not well studied. The present study was to evaluate the effects of iAs and F individual or combined exposure on endothelial activation
Arsenic and fluoride induce neural progenitor cell apoptosis.
The aim of the present study is to determine the effect of inorganic arsenic (As) and its metabolites on the viability of the neural progenitor cell (NPC) line C17.2, in order to evaluate cellular mechanisms involved in As developmental neurotoxicity. Moreover, we analyzed the effects of the coexposure to As
Effect of fluoride on expression of pura gene and CaM gene in newborn rat osteoblasts.
To explore the effect of fluoride (F) on the expression of purine-rich element-binding protein (PURA) gene and calmodulin (CaM) gene in osteoblasts of newborn rats, parietal calvaria bone osteoblast cultures of 48-hr-old rats were treated for 48 hr with sodium fluoride (NaF) at concentrations of 0 (control), 0.5, 2, and
[Study on the relationship between renal apoptosis and expression of caspase protein in fluoride induced rat].
OBJECTIVE: To study the relationship between death receptor pathway, mitochondrion pathway and fluoride-induced apoptosis of renal cell. METHODS: Male Sprague-Dawley rats were divided randomly into four groups (control, low-fluoride, medium-fluoride,and high-fluoride) and administered 0, 50, 100, and 200 mg/L of sodium fluoride, respectively, via drinking water for 120 days. The incidence
ZIP1 and zinc inhibits fluoride-induced apoptosis in MC3T3-E1 cells.
Excess fluoride intake could induce apoptosis in the cells. As an essential micronutrient and cytoprotectant, zinc is involved in many types of apoptosis. Here, we studied the effects of zinc and ZIP1 on fluoride-induced apoptosis in mouse MC3T3-E1 cells and examined the underlying molecular mechanisms. Our study found that fluoride
