Despite thyroid tissue heterogeneity, biochemical and morphological features have been associated with certain thyroid diseases. We analyzed the ultracytochemical localization of thyroperoxidase (TPO), TPO-associated hydrogen peroxide-generating site

The effects of the tri-iodothyronine (T(3)) secreted by thyroid cells on the growth of the thyrocyte are poorly known. In this study we analyzed the effects of T(3) on the proliferation of bovine thyroid follicles in primary culture previously deplet

Summary Insulin-like growth factor I (IGF-I) downregulates growth hormone (GH) expression in pituitary cell cultures. However, in vivo different results were found depending on the experimental protocol used. We determined the kinetics of changes of

Nitric oxide (NO) has been proposed as an intracellular signal in the thyroid. The NO effect on function and morphology of bovine thyroid follicles in culture was analyzed by using the NO donors sodium nitroprusside (SNP) and S-nitrosoglutathione (GS

To establish biochemical and functional relations during thyroid development, the activity of thyroid peroxidase (TPO), nicotinamide adenine dinucleotide phosphate (NADPH)-cytochrome c reductase and monoamine oxidase (MAO) in a particulate fraction a

The present work was addressed to study a possible relationship between monoamine oxidase (MAO) and the thyroid iodide transport mechanism. Normal rats treated with clorgyline (a selective MAO-A inhibitor) or tranylcypromine (a non-selective MAO inhi

The characteristics and regulation of monoamine oxidase (MAO) were studied in rat thyroid tissue. A measured Michaelis constant (Km) value of 102 μmol/l was similar to the Km values found in other tissues. Maximal velocity (Vmax) was 1·028 nmol/mg

Monoamines are able to increase the thyroid iodine organification in vitro. A predominance of the A form of monoamine oxidase (MAO) has been previously demonstrated to exist in bovine thyroid tissue. In the present study we have investigated the form

Summary Objective Turner syndrome (TS) is an indication for GH therapy in spite of the modest growth response. Somatic growth depends not only on GH insulin-like growth factor I (IGF-I) axis but also on thyroid hormone (TH) status. We have previously
