Description

Recently, thyroid follicular cells were shown to exhibit atrial natriuretic factor (ANF)-like immunoreactivity and high affinity ANF receptors. In this study, we therefore examined the effects of synthetic rat ANF1-28 on basal and stimulated thyroid hormone secretion in the mouse, according to the McKenzie technique. Iodine deficient mice were pretreated with 125I and thyroxine. ANF (3 nmol/animal) was found to inhibit the increase in blood radioiodine levels that was induced by TSH or vasoactive intestinal polypeptide (VIP). Furthermore, ANF and norepinephrine additively inhibited the TSH-induced increase in blood radioiodine levels. It is concluded that ANF inhibits thyroid hormone secretion, which, therefore, might be locally regulated by intrathyroidal ANF
