1589 Objectives Higher concentrations of thyreotropin (TSH) have to be considered as an
exogenic stress factor. Using two poorly differentiated thyroid carcinoma cell lines we …

Apoptosis plays an important role within the endocrine system, particularly in the thyroid
gland, although little is known about its regulation in normal thyroids. Because thyrotropin …

631 Objectives: Studies on the effect of an external irradiation on cell vitality, cell necrosis
and the appearance of DNA damage. Especially, the potential radioprotective/antioxidative …

Background: Poorly differentiated thyroid carcinoma (PDTC) has an unfavorable prognosis.
Surgical management is the principal treatment approach. In addition, radioiodine treatment …

Data and arguments are presented that provide evidence of a role played by thyroid
hormones (TH) in cell reliability improvement. This role may be determined by synergistic TH …

Abstract Background and Objectives Differences in the expression levels of Thyroglobulin
(Tg), Thyroid peroxidase (TPO) and thyrotropin receptor (TSH‐R) in primary and recurrent …

Hypothyroidism is a protective factor against breast cancer but long-term exposure or
overdoses of thyroid replacement therapy with thyroxine (T 4) may increase breast cancer …

OBJECTIVE: Although endocrine therapy of papillary thyroid carcinoma (PTC) by inhibiting
thyroid-stimulating hormone (TSH) has been used for many years, its mechanism of action is …

Apoptosis has been shown to be involved in endocrine tissue homeostasis as well as
regression due to hormone deprivation. The goal of this study was to induce apoptosis and …

Objective: To observe the expression and significance of hormothyrin and thyroid hormone
in thyroid cancer. Methods: The expression of hormothyrin (TSH) and thyroid hormone (TT3 …
