Objective:To explore the role of excessive iodide in inducing apoptosis in thyroid cells and its mechanism.Methods:Normal primary thyroid cells were cultured in NaI of different concentrations with or without IL-1β and methimazole.The morphological changes in thyroid cells were observed by light microscopy and apotosis rate was determined by flow cytometry techique.In the meantime Fas
FasL
p53 level were determined by histochemistry.Results:Thyroid cells treated with iodide excess underwent the morphological changes and apoptosis. There was a gradually increased apotosis rate and Fas/FasL protein expression accompanying increase in iodide concentrations.No changes in p53 protein expression was shown. IL-1β enhanced the effect of iodide cytotoxicity
whereas methimazole inhibited the role of iodide inducing apotosis.Conclusion:These data indicate that excess molecular iodide induces apoptosis in thyroid cell through Fas/FasL channel
