physiology. The ability of the thyroid gland to accumulate radioiodine is also important for the diagnosis and treatment of thyroid disorders ( Mazaferri 2000 ). TSH is the major regulator of thyroid cell proliferation, differentiation, and function

Introduction Central congenital hypothyroidism (CCH) is a rare disorder in which inadequate thyroid hormone biosynthesis occurs due to defective stimulation of a normal thyroid gland by thyroid stimulating hormone (TSH). The underlying molecular

(TSH)-induced uptake of iodide and the release of organified iodine in normal human thyrocytes ( Namba et al. 1993 ). High concentrations of retinol also exert dedifferentiating effects on normal thyrocytes ( Fröhlich et al. 2001 ). These effects

intracerebroventricular administration of NPY to normally fed rats resulted in reduction of circulating levels of thyroid hormones with inappropriately normal or low thyrotropin (TSH), and suppression of proTRH mRNA in the hypothalamic paraventricular nucleus (PVN

) the β-adrenergic receptor kinases (GRK2 and GRK3), and 3) the GRK4, GRK5, and GRK6 subfamily ( Ribas et al . 2007 ). The thyrotropin (TSH) receptor belongs to the GPCR family and is a major determinant of thyroid function ( Vassart & Dumont 1992

Introduction Thyroid hormones are produced and released by the thyroid gland, which regulate the metabolism of the body. The endocrine function of the thyroid gland is mediated by TSH, a glycoprotein hormone produced by the anterior pituitary
