""Among the systemic factors, the expression of D1, D2, D3, TRα,TRβ and GHR in hind limb of B. gargarizans larvae were downregulated in 10 mg F−/L group compared to control group...Exposure to 1, 5, 10 and 20 mg F−/L, a significant decrease of Dio2 mRNA levels was detected in hind limb of B. gargarizans at G40. Besides, significant down-regulation of the mRNA expression of Dio2 were observed in hind limb of B. gargarizans exposed to 10 and 20 mg F−/L larvae at Gs 42. However, Dio2 mRNA levels did not have significant difference between controls and experimental concentrations at Gs46. Both Dio3 and TRα exhibited same developmental expression patterns to the mRNA expression of Dio2. The mRNA expression level of TRβ was down-regulated significantly downregulated in both 10 and 20 mg F−/L groups compared to the control group at G40 and G42, respectively."

First, fluoride causes an increase in D1, then, after 90 days, a severe decrease. (Compare to Zhao et al., 1998;1992)

"mRNA expression of Dio1 and MCT8 increased significantly in NCG compared with those in the control group, indicating that fluoride improved Dio1 and MCT8 activities, promoted transmembrane deiodination of T4 and decreased serum levels of T4. These trends in Dio1, MCT8 and T4 are consistent with other studies. In theory, increased Dio1 and MCT8 activities leads to more T4 being converted to T3 over the short term, which would increase serum T3 levels. However, our experimental results show that fluoride treatment decreased T4 and T3 levels at the same time. This may have occurred because fluoride ions increased Dio1 activity, which catalysed T3 further to T2 or monoiodotyrosine, decreasing serum T4 and T3 levels in NCG mice."

"According to real-time PCR results, exposure to fluoride upregulated Dio3 and TRβ mRNA expression and downregulated Dio2 and TRα mRNA level. All above indicated that excessive fluoride could induce morphology malformations, inhibit embryonic growth and development, and disrupt the normal function of maternal thyroid hormone in B. gargarizans embryos."

"However, our study suggests that high dose fluoride could damage follicular cells in thyroid, and thyroid damage results in up-regulation of D3 gene expression and a sharp reduction in thyroid hormone. The decrease of TH had double adverse effects: one is that it delays complete metamorphosis; the other is that it retards ossification and inhibits calcium deposition in bone."
