Alterations of apoptosis and expressions of Bax and Bcl-2 in the cerebral cortices of rats with chronic fluorosis
The aim of the study was to investigate the influence of chronic fluorosis on apoptosis and the expression of Bax and Bcl-2 in the cerebral cortices of rats in an attempt to elucidate molecular mechanisms. Sixty Sprague Dawley (SD) rats were divided randomly into three groups of 20 each: an
Fluoride-induced thyroid cell apoptosis
In addition to causing skeletal and dental fluorosis, fluoride (F) in drinking water may damage other organs including the thyroid. The objective of this study was to explore the toxicity of F on immortalized human normal thyroid cells (Nthy-ori 3-1) exposed to 0, 0.1, 1, and 3 mmol/L of sodium
Sodium fluoride induces apoptosis in mouse embryonic stem cells through ROS-dependent and caspase- and JNK-mediated pathways
Sodium fluoride (NaF) is used as a source of fluoride ions in diverse applications. Fluoride salt is an effective prophylactic for dental caries and is an essential element required for bone health. However, fluoride is known to cause cytotoxicity in a concentration-dependent manner. Further, no information is available on the
Effects of tyrosine kinase inhibitors on cell death induced by sodium fluoride and pertussis toxin in the pancreatic beta-cell line, RINm5F.
1. Sodium fluoride causes apoptosis of pancreatic beta-cells and this response is enhanced by pre-treatment with pertussis toxin. In the present study, tyrosine kinase inhibitors were used to investigate the mechanisms of action of NaF and pertussis toxin in the beta-cell line, RINm5F. 2. Exposure of RINm5F cells to low concentrations
Triclosan: cytotoxicity, mode of action, and induction of apoptosis in human gingival cells in vitro.
The in vitro cytotoxicology of triclosan, the active ingredient in some mouthrinses and dentifrices used in the prevention and treatment of gingivitis and plaque, was studied using the Smulow-Glickman (S-G) human gingival epithelial cell line. The 24 h midpoint cytotoxicity value was 0.05-0.06 mM triclosan as assessed with the neutral
