Sodium fluoride strongly activated MAPK, in particular JNK1/2 and p38.
The ERK1/2-inhibitor PD98059, the p38-inhibitor SB202190 and the JNK1/2-inhibitor SP600125 partially inhibited the fluoride-induced IL-8 response.

In order to reveal the mechanism of the decreased ability of learning and memory induced by chronic fluorosis, nicotinic acetylcholine receptors (nAChRs) and the pathway of extracellular signal regulated protein kinase (ERK1/2) were investigated by using the rats fed with different concentrations of sodium fluoride for 6 months.

The phosphatase activity of the recombinant LMW-DSPs was inhibited by orthovanadate but not sodium fluoride.
However, none of the DSPs could dephosphorylate MAP kinases such as ERK1, p38, and SAPK/JNK in transiently transfected COS7 cells under the conditions used.

Similarly, diminished stimulation of adenylyl cyclase by GTPgammaS, isoproterenol and sodium fluoride in SHR was also restored towards control WKY rat levels by NAC and DPI treatments.
In addition, the enhanced activity of extracellular signal-regulated kinase 1/2 in SHR as compared with WKY rats, as demonstrated by enhanced phosphorylation of extracellular signal-regulated kinase 1/2, was also restored to WKY rat levels by NAC or DPI.

Recombinant LMW-DSP2 protein exhibited phosphatase activity toward an artificial low molecular weight substrate para-nitrophenyl phosphate, and the activity was inhibited completely by sodium orthovanadate but not sodium fluoride, pyrophosphate, and okadaic acid.
