                                 Thyroid hormone



Thyroid hormone (triiodothyronine (T3) and thyroxine (T4)), produced by the thyroid gland, plays an important role in regulation of metabolism, including directly boosts energy metabolism and triggers rapid protein synthesis and regulates mitochondrial gene transcription, etc. Iodine is necessary for the production of T3and T4, deficiency of Iodine can lead to enlarge thyroid grand and goitre.


     Thyroid hormone: Radioiodine treatment and oxidative stress in thyroidectomised patients


Post-operative radioiodine treatment of differentiated thyroid cancer occupies a well determined place in the treatment policy of this disease. In the study to measure erythrocyte malondialdehyde (MDA) levels, as a marker of lipid peroxidation, erythrocyte reduced glutathione (GSH) levels and activities of GSH-Peroxidase and GSH-Reductase as antioxidants, showed that erythrocyte MDA levels were significantly higher, and erythrocyte GSH levels and activities of GSH-related enzymes were significantly lower in thyroidectomised patients after surgery than in healthy controls. Additionally, according to their thyroid hormone levels the patients had hypothyroidism at this time. In patients 2 days after radioiodine treatment both MDA and GSH levels and GSH-related enzyme activities were significantly increased when compared to their own initial levels(18).

     Thyroid hormone and  Oxidative stress


The liver metabolizes the thyroid hormones and regulates their systemic endocrine effects so liver disease could affect thyroid hormone metabolism. In the study to investigate serum levels of oxidative stress and antioxidant in liver diseases as prognostic markers and know the importance of these antioxidants level in relation to thyroid hormones, researchers at the Ain Shams University, found that measurement of the total T(3), NO, MDA, GSH reduced and GSHPx as biomarkers for liver diseases might be a beneficial tool, helping in monitoring the state of liver disease patients.(17).

In the study of Chemiluminescent and respiratory responses in the liver of rats treated with 0.1 mg of triiodothyronine (T3)/kg for 1 to 7 days, showed that the calorigenic response in the hyperthyroid state is accompanied by the development of an hepatic oxidative stress characterized by enhanced spontaneous chemiluminescence, enhanced NADPH-dependent microsomal respiration and a decreased antioxidant cellular activity(16).

In the study to measure the thyroxine 5'-deiodinase I (T(4)5'D-I) activity in thyroid, liver, and kidney and thyroxine 5'-deiodinase II (T(4)5'D-II) activity in brown adipose tissue (BAT) in rats on a low-iodine diet (LID) and to test the possibility that increased deiodinase activity in these tissues might contribute to the maintenance of ther serum 3,5,3'-triiodothyronine (T3) level, found that increased thyroxine(T4)-to-T3 conversion in the greatly enlarged thyroids of LID rats contributed to the maintenance of serum T3. T(4)5'D-II activity in BAT was markedly increased in LID rats and was further greatly increased on cold exposure(15).

     Thyroid hormone: Thyronamines and body temperature and heart rate



The thyronamines which are decarboxylated thyroid hormones initiating physiological actions like lowering body temperature and heart rate, thereby acting in opposite direction to the classical thyroid hormones. So far it is believed that thyronamines function via the activation of a G-protein coupled receptor, TAAR1. The objective of this review is to summarise the recent findings in thyroid hormone synthesis and action and to discuss their implications for diagnosis of thyroid disease and for treatment of patients, according to the study by Institute of Experimental Pediatric Endocrinology, Charité Universitätsmedizin Berlin(14).

     Thyroid hormone: Triiodothyronine stimulates glucose transport in bone cells


In the study to evaluate whether 3,3',5-triiodo-l-thyronine (T₃) stimulates the uptake of glucose in osteoblastic cells, PyMS (a cell line derived from rat bone) cells were kept in serum-free culture medium and treated with T₃, found that T₃ did not influence the cell number but slightly (1.3-fold) increased the protein content of the cell cultures. 2DG ([1-¹⁴C]-2-deoxy-D: -glucose)uptake was low in serum-deprived cell cultures and was increased by T₃ (up to 2.5-fold at 1 nmol l⁻¹ after 4 days) in a dose- and time-dependent manner. Triiodothyronine at 1 nmol l⁻¹ increased GLUT1 and GLUT3 abundance in membranes. Therefore, increased glucose uptake induced by T₃ in osteoblasts may be mediated by the known high-affinity glucose transporters GLUT1 and GLUT3(13).

     Thyroid hormone and skeletal growth

Understanding how bone growth is regulated by hormonal and mechanical factors during early growth periods is important for optimizing the attainment of peak bonemass to prevent or postpone the occurrence of fragility fractures later in life. According to the study by Musculoskeletal Disease Center, Loma Linda VA HealthCare System , there is an important period prior to puberty when the effects of GH are surprisingly small and TH plays a critical role in the regulation of skeletal growth. Daily administration of T3/T4 during days 5 to 14, the time when serum levels of T3 increase rapidly in mice, rescued the skeletal deficit in TH-deficient mice but not in mice lacking both TH and GH. However, treatment of double-mutant mice with both GH and T3/T4 rescued the bone density deficit. Increased body fat in the TH-deficient as well as TH/GH double-mutant mice was rescued by T3/T4 treatment during days 5 to 14(12).
