Thyroid Hormone and Cardioprotection

Comprehensive Physiology, 2016
ABSTRACT The heart is a major target of thyroid hormones, with maintenance of euthyroid hormone balance critical for proper function. In particular, chronic low thyroid function can eventually lead to dilated heart failure with impaired coronary blood flow.

Thyroid hormone resistance

Annals of Clinical Biochemistry: International Journal of Laboratory Medicine, 2006
Resistance to thyroid hormone (RTH) is a rare autosomal dominant inherited syndrome of reduced end-organ responsiveness to thyroid hormone. Patients with RTH have elevated serum free thyroxine (FT4) and free triiodothyronine (FT3) concentrations and normal or slightly elevated serum thyroid stimulating hormone (TSH) level.

Resistance to Thyroid Hormone

Hormone Research, 2009
Resistance to thyroid hormone (RTH) is usually dominantly inherited and is characterized by elevated free thyroid hormones in the serum and failure to suppress pituitary thyroid stimulating hormone (TSH) secretion with variable refractoriness to hormone action in peripheral tissues.

Novel thyroid hormones

Endocrine, 2019
The field of thyroid hormone signaling has grown more complex in recent years. In particular, it has been suggested that some thyroid hormone derivatives, tentatively named "novel thyroid hormones" or "active thyroid hormone metabolites", may act as independent chemical messengers.

Metabolism of the Thyroid Hormones

Hormone Research, 2008
This review covers the current knowledge about the various metabolic pathways involved in the conversion of thyroid hormones to the thyromimetically active and inactive iodothyronines. The concerted mechanism of systemic and local production of iodothyronines by tissue-specific iodothyronine deiodinase isozymes will ultimately determine the expression ...

Thyroid Hormone Deiodination

Thyroid, 1990
A case is presented of Graves' disease occurring in a patient with hemiagenesis of the thyroid gland. The diagnosis was suspected clinically and was confirmed by laboratory tests and imaging studies, as well as by the presence of thyroid-stimulating antibody.

Thyroid hormones and the heart

Hormone Molecular Biology and Clinical Investigation, 2014
Abstract Thyroid hormones have a significant impact on heart function, mediated by genomic and non-genomic effects. Consequently, thyroid hormones deficit as well as excess are expected to result in profound changes in cardiac function regulation and cardiovascular hemodynamics.

Thyroid hormone and angiogenesis

Vascular Pharmacology, 2010
In models of thyroid hormone-induced cardiac hypertrophy, there is appropriate, supportive angiogenesis. Twenty years ago in one such model, angiogenesis in response to the hormone was observed before hypertrophy developed and it is now understood that iodothyronines induce neovascularization in a variety of settings, including the heart, ischemic ...

Thyroid Hormones and Derivatives: Endogenous Thyroid Hormones and Their Targets

2018
More than a century after the discovery of L-Thyroxine, the main thyroid hormone secreted solely by the thyroid gland, several metabolites of this iodinated, tyrosine-derived ancestral hormone have been identified. These are utilized as hormones during development, differentiation, metamorphosis, and regulation of most biochemical reactions in ...

The Transport of Thyroid Hormones

Clinical Science, 1983
1. Hormones have to be transported from their sites of synthesis to their target organs. For lipophilic hormones, such as steroids and thyroid hormones, transport is accomplished by binding to specific serum proteins, in the case of thyroxine (T4) and tri-iodothyronine (T3) to thyroxine-binding globulin (TBG) and prealbumin (PA).
