Effects of lithium on stimulated metabolic parameters in dog thyroid slices


, : Effects of lithium on stimulated metabolic parameters in dog thyroid slices. Acta Endocrinologica 121(5): 615-620

Thyroid abnormalities may develop during chronic lithium therapy for affective disorders. Lithium, like iodide, inhibits TSH stimulation of adenylate cyclase and thyroid hormone release. The present study examined the effect of lithium on stimulation of intrathyroidal intermediary metabolism by several agonists. LiCl (5 mmol/l) did not inhibit basal cAMP, glucose oxidation or 32P incorporation into phospholipids in dog thyroid slices. Although LiCl inhibited TSH stimulation of cAMP, it did not abolish the hormone's effect on cAMP-dependent protein kinase. The stimulation of iodide organification, glucose oxidation or 32P incorporation into phospholipids by TSH, carbachol and phorbol esters was not inhibited by lithium. This is in contrast to the effects of iodide, which inhibited stimulation of glucose oxidation and 32P incorporation into phospholipids by various agonists. Thus, although both lithium and iodide inhibited TSH-stimulated cAMP formation, they act differently on intrathyroidal intermediary metabolism.
