Thyrotropin (TSH) is a well-accepted thyrocyte
growth factor .
Anti-thyroid peroxidase (TPO), located at the apical membrane of the thyrocyte
, is essential for thyroid hormone synthesis, catalysis of iodine oxidation, iodination of tyrosine residues in Tg (Thyroglobulin) and coupling of the iodothyrosines into thyroxine (T4) and triiodothyronine (T3).
Most patients present with mild signs of thyrotoxicosis and possible neurological features, due to pituitary mass; they often have thyroid nodule disease.[sup], Apparently, TSH is the primary mediator of thyrocyte
proliferation.[sup] TSHomas may be associated with thyroid diseases, and in diagnosing TSHoma, the possibility of thyroid disease should be investigated and followed up.
Additionally, in vitro studies have shown that lithium increases thyrocyte
proliferation by Wnt/[beta] signaling (5,6).
Sodium ioidide symporter glycoprotein is necessary for the efficiency of RAI treatment as it is responsible for the iodine transport across the thyrocyte
The thyrotropin receptor and the regulation of thyrocyte
function and growth.
Iodine131 induces apoptosis in HTori-3 human thyrocyte
cell line and G2/M phase arrest in a p53-independent pathway.
This defect is the result of impaired expression/function of the sodium/iodine symporter (NIS) or thyroperoxidase (TPO) caused by oncogene-activated signaling that leads to thyrocyte
The effects of diosgenin in a mouse model of Graves' disease were also investigated and it was observed that this steroid can relieve goiter through the inhibition of thyrocyte
Additionally, iodine deficiency of the area results in an increase of serum TSH which represents the major regulator of the growth and the thyrocyte
's differentiation and proliferation [30, 31].
