Effect of fluoride on glycerol production in rat adipocytes in vitro.
The effect of 10 mM fluoride on glycerol production in vitro from rat epididymal adipocytes was investigated. Fluoride had no effect on the basal glycerol production, irrespective of the presence or absence of Ca++ and Mg++ ions. When stimulating the glycerol production with 10 mM theophylline, fluoride reduced the stimulation in the absence of either Ca++ or Mg++ or both. In the presence of both ions, fluoride had no effect on the theophylline stimulation. Fluoride also reduced the stimulative effect of adrenaline on glycerol production, but not that of glucagon. Increased adrenaline concentration could not overcome the inhibitory effect of fluoride.
