Summary

Rat thyroid slices were submitted to different effectors and hormones in order to investigate their action on the phosphatidylinositol metabolism. Fluoride and vanadate induced a clear increase of the inositol phosphates with half maximal stimulation at 7 mM and 8 mM respectively. The inositol bisphosphate (IP2) and inositol trisphosphate (IP3) accumulation induced by vanadate was relatively higher than that observed in the case of fluoride stimulation. Carbachol stimulated also the generation of inositol phosphates with half maximal activation at 2.5 x 10-6M. In the same conditions, no significant effect on inositol phosphates production could be detected by the action of TSH or TRH.
