The prevalence of thyroid diseases including autoimmune hyperthyroidism (Graves’ disease), thyroiditis, and different forms cancer is increasing every year, while the effectiveness their treatment remains low limited, mainly, to replacement therapy with hormones surgical radioisotope methods. This review presents current state problem pharmacological correction in new approaches regulation func...

The possibility that the elasmobranch pituitary contains thyroid stimulating hormone (TSH) activity was investigated by measuring the increase in the release of thyroxine from thyroid glands of the Atlantic stingray, Dasyatiq sabina, incubated with homogenates of various pituitary regions. The ventral lobe of the pars distalis contained most of the TSH activity, with lesser amounts in the neuro...

background: thyroid carcinoma is the most common malignancy of the endocrine system. papillary thyroid carcinoma (ptc) is the most common type of thyroid cancer, accounting for 70–90% of well-differentiated thyroid malignancies. thyroid papillary microcarcinoma is a subtype of papillary carcinoma that included tumors with less than 10mm diameter. as a result of diagnostic methods improvement, p...

BACKGROUND Anaplastic thyroid cancer is considered to be one of the most aggressive human malignancies, and the mean survival time after diagnosis is approximately six months, regardless of treatments. This study aimed to examine how EpCAM and its related molecules are involved in the characteristics of anaplastic thyroid carcinoma. METHODOLOGY/PRINCIPAL FINDINGS Two differentiated thyroid ca...

This work analyzes the effects of Satureja khuzestanica essential oil (SKEO) on the thyroid and antioxidant system, assessed by measuring levels of tri-iodothyronine (T3), thyroxine (T4), thyroid-stimulating hormone (TSH), malondialdehyde (MDA), reduced glutathione (GSH), and glutathione peroxidase (GPx) activity. Forty adult male Sprague Dawley rats (225 ± 25 g) were divided into five...

Glucuronidation of iodothyronines in rat liver is catalyzed by at least three UDP-glucuronyltransferases (UGTs): bilirubin UGT, phenol UGT, and androsterone UGT. Bilirubin and phenol UGT activities are regulated by thyroid hormone, but the effect of thyroid status on hepatic glucuronidation of iodothyronines is unknown. We examined the effects of hypothyroidism induced by treatment of rats with...

There is evidence that the sympathetic nervous system exerts a control on human thyroid function via an adrenergic innervation of follicle cells. The present study demonstrates that cholinergic nerve fibers also reach follicle cells in the normal human thyroid. In addition, cholinergic agents were found to enhance cGMP accumulation in human thyroid tissue. This effect was blocked by atropine, a...

Deiodinases constitute a group of thioredoxin fold-containing selenoenzymes that play an important function in thyroid hormone homeostasis and control of thyroid hormone action. There are three known deiodinases: D1 and D2 activate the pro-hormone thyroxine (T4) to T3, the most active form of thyroid hormone, while D3 inactivates thyroid hormone and terminates T3 action. A number of studies ind...
