Expression of Fas, FasL, and NF-kappa B in the process of osteoclast-like cell apoptosis effected by sodium fluoride / 中国医学科学院学报

ABSTRACT

<p><b>OBJECTIVE</b>To detect the changes in the expression of apoptosis signals Fas, FasL and NF-kappa B in the process of osteoclast-like cell (OLC) apoptosis effected by sodium fluoride.</p><p><b>METHODS</b>After co-culture of osteoclast-like cells with 0, 5, 10 and 15 mg/L sodium fluoride, Fas, FasL and NF-kappa B antibody expressions were detected by immune-histochemistry.</p><p><b>RESULTS</b>The expression of Fas and FasL increased with the concentration of the sodium fluoride, however the expression of NF-kappa B decreased with the concentration of sodium fluoride.</p><p><b>CONCLUSION</b>In the process of OLC apoptosis induced by sodium fluoride, the expression of Fas and FasL increased, and that of NF-kappa B decreased with the concentration of sodium fluoride respectively, and the changes of the expression present a dose-dependent pattern.</p>
