Mechanism of Action of the Thyroid Hormone on the Heart
SUMMARY The foliowing cardiac effects may be attributed to thyroxin: 1-Thyroxin augments all anaerobic processes in the body includ::ng the heart, and decreases the glycogen content of the heart ( 1, 2, 5, 27). The resistance of the heart to anoxia is increased in hyperthyroidism ( 25). 2- Thyroxin influences the cardiac weight and prevents cardiac atrophy (3, 8, 10, 11, 19, 20, 21, 30...
متن کاملSpecificity of thyroid hormone receptor subtype and steroid receptor coactivator-1 on thyroid hormone action.
Isoforms of the thyroid hormone receptor (TR)alpha and TRbeta genes mediate thyroid hormone action. How TR isoforms modulate tissue-specific thyroid hormone (TH) action remains largely unknown. The steroid receptor coactivator-1 (SRC-1) is among a group of transcriptional coactivator proteins that bind to TRs, along with other members of the nuclear receptor superfamily, and modulate the activi...
متن کاملThyroid hormone action in the absence of thyroid hormone receptor DNA-binding in vivo.
Thyroid hormone action is mediated by thyroid hormone receptors (TRs), which are members of the nuclear hormone receptor superfamily. DNA-binding is presumed to be essential for all nuclear actions of thyroid hormone. To test this hypothesis in vivo, the DNA-binding domain of TR-beta was mutated within its P-box (GS mutant) using gene targeting techniques. This mutation in vitro completely abol...
متن کاملFreedom of expression beyond the thyroid: the thyroid- stimulating hormone receptor in the adipocyte
Introduction The TSH receptor (TSHR) enables thyrocytes to recognize and respond to TSH secreted by pituitary thyrotrophs. It regulates thyrocyte proliferation as well as thyroid hormone production and secretion. Expression of functional TSHR occurs outside of the thyroid gland, and there is ongoing interest in understanding what role TSHR may play in these extra-thyroidal sites. In this regard...
متن کاملThyroid hormone action on liver, heart, and energy expenditure in thyroid hormone receptor beta-deficient mice.
Thyroid hormone (TH) responsive genes can be both positively and negatively regulated by TH through receptors (TR) alpha and beta expressed in most body tissues. However, their relative roles in the regulation of specific gene expression remain unknown. The TR beta knockout mouse, which lacks both TR beta1 and TR beta2 isoforms, provides a model to examine the role of these receptors in mediati...
