ClC-3 is necessary to prevent fluoride entrance. (A) Q-PCR results. Treatment with Clcn3-specific siRNA downregulated Clcn3 expression by 80% in mouse ameloblast LS8 cells. (B) Comparison of intracellular chloride. Compared with the control, intracellular chloride levels (labeled with MQAE dye) were significantly higher in both 2 mM and 5 mM NaF-treated control groups, whereas no increase was observed in the Clcn3 siRNA-transfected group. (C) Comparison of intracellular concentration of fluoride. The control group exhibited a significant increase in fluorescence after NaF treatment, whereas the Clcn3 siRNA group showed only a weak, non-significant rise in fluoride uptake.
