Iodothyronine deiodinases (EC 1.21.99.4 and EC 1.21.99.3) are a subfamily of deiodinase enzymes important in the activation and deactivation of thyroid hormones. Thyroxine (T4), the precursor of 3,5,3-triiodothyronine (T3) is transformed into T3 by deiodinase activity. T3, through binding a nuclear thyroid hormone receptor, influences the expression of genes in practically every vertebrate cell. Iodothyronine deiodinases are unusual in that these enzymes contain selenium, in the form of an otherwise rare amino acid selenocysteine. These enzymes are not to be confused with the iodotyrosine deiodinases that are also deiodinases, but not members of the iodothyronine family. The iodotyrosine deiodinases (unlike the iodothyronine deiodinases) do not use selenocysteine or selenium. The iodotyrosine enzymes work on iodinated single tyrosine residue molecules to scavenge iodine, and do not use as substrates the double-tyrosine residue molecules of the various iodothyronines. In tissues, deiodinases can ...

Recent studies in the field of autoimmune thyroid diseases have largely focused on the delineation of B-cell auto-epitopes recognized by the main autoantigens to improve our understanding of how these molecules are seen by the immune system. Among these autoantigens which are targeted by autoantibodies during the development of autoimmune thyroid diseases, thyroid peroxidase is a major player. Indeed, high amounts of anti-thyroid peroxidase autoantibodies are found in the sera of patients suffering from Graves disease and Hashimotos thyroiditis, respectively hyper and hypothyroidism. Since anti-thyroid peroxidase autoantibodies from patientssera mainly recognize a discontinuous immunodominant region on thyroid peroxidase and due to the complexity of the three dimensional structure of human thyroid peroxidase, numerous investigations have been necessary to closely localize this immunodominant region. The aim of the present review is to summarize the current knowledge regarding the localization of the

Type II iodothyronine deiodinase (iodothyronine 5-deiodinase, iodothyronine 5-monodeiodinase) is an enzyme that in humans is encoded by the DIO2 gene. The protein encoded by this gene belongs to the iodothyronine deiodinase family. It activates thyroid hormone by converting the prohormone thyroxine (T4) by outer ring deiodination (ORD) to bioactive 3,3,5-triiodothyronine (T3). It is highly expressed in the thyroid, and may contribute significantly to the relative increase in thyroidal T3 production in patients with Graves disease and thyroid adenomas. This protein contains selenocysteine (Sec) residues encoded by the UGA codon, which normally signals translation termination. The 3 UTR of Sec-containing genes have a common stem-loop structure, the Sec insertion sequence (SECIS), which is necessary for the recognition of UGA as a Sec codon rather than as a stop signal. Alternative splicing results in multiple transcript variants encoding different isoforms. DIO2 has been shown to interact ...

Cells are not passive bystanders in the process of hormonal signaling and instead can actively customize hormonal action. Thyroid hormone gains access to the intracellular environment via membrane transporters, and while diffusing from the plasma membrane to the nucleus, thyroid hormone signaling is modified via the action of the deiodinases. Although the type 2 deiodinase (D2) converts the prohormone T4 to the biologically active T3, the type 3 deiodinase (D3) converts it to reverse T3, an inactive metabolite. D3 also inactivates T3 to T2, terminating thyroid hormone action. Therefore, D2 confers cells with the capacity to produce extra amounts of T3 and thus enhances thyroid hormone signaling. In contrast expression of D3 results in the opposite action. The Dio2 and Dio3 genes undergo transcriptional regulation throughout embryonic development, childhood, and adult life. In addition, the D2 protein is unique in that it can be switched off and on via an ubiquitin regulated mechanism, triggered ...

The present study was undertaken to determine whether the capacity for 3,5,3′,5′-tetraiodothyronine (T4) conversion into 3,5,3′-tri-iodothyronine (T3), as measured by the activity of thyroxine type II 5′-monodeiodinase (T4-5′D), was altered in the brains of young Zucker fa/fa rats during the period of intense maturation of the central nervous system (i.e. from 10 to 20 days of life). From 7 to 14 days of age, no difference in brain T4-5′D activity could be detected between lean and pre-obese rats; serum free T4 was not affected by the fa gene. During the suckling to weaning transition, T4-5′D reached a plateau in brains of lean rats, while it increased by 50% in brains of pre-obese rats; concurrently, serum free T4 increased in Fa/fa rats, whereas it did not change in fa/fa rats. The increased capacity for conversion of T4 into T3 observed in brains of pre-obese compared with lean rats could not be ascribed to a variation in the amount of T4-5′D, since Vmax. did not differ ...

Thyroid hormones are required for human brain development, but data on local regulation are limited. We describe the ontogenic changes in T(4), T(3), and rT(3) and in the activities of the types I, II, and III iodothyronine deiodinases (D1, D2, and D3) in different brain regions in normal fetuses (13-20 wk postmenstrual age) and premature infants (24-42 wk postmenstrual age). D1 activity was undetectable. The developmental changes in the concentrations of the iodothyronines and D2 and D3 activities showed spatial and temporal specificity but with divergence in the cerebral cortex and cerebellum. T(3) increased in the cortex between 13 and 20 wk to levels higher than adults, unexpected given the low circulating T(3). Considerable D2 activity was found in the cortex, which correlated positively with T(4) (r = 0.65). Cortex D3 activity was very low, as was D3 activity in germinal eminence and choroid plexus. In contrast, cerebellar T(3) was very low and increased only after midgestation. Cerebellum ...

Brown adipose tissue (BAT; brown fat) is the principal site of adaptive thermogenesis in the human newborn and other small mammals. Of paramount importance for thermogenesis is vascular perfusion, which controls the flow of cool blood in, and warmed blood out, of BAT. We have developed an optical method for the quantitative imaging of BAT perfusion in the living, intact animal using the heptamethine indocyanine IR-786 and near-infrared (NIR) fluorescent light. We present a detailed analysis of the physical, chemical, and cellular properties of IR-786, its biodistribution and pharmacokinetics, and its uptake into BAT. Using transgenic animals with homozygous deletion of Type II iodothyronine deiodinase, or homozygous deletion of uncoupling proteins (UCPs) 1 and 2, we demonstrate that BAT perfusion can be measured non- invasively, accurately, and reproducibly. Using these tech- niques, we show that UCP ¡1/¡2 knockout animals, when compared to wild-type animals, have a higher baseline perfusion ...

Our studies of the zebrafish reveal that the dio3 gene is duplicated in this species and that embryonic deiodination is an important determinant of embryo size. Although both dio3 paralogs encode enzymatically active proteins with high affinity for thyroid hormones, their anatomic patterns of ...

N2 - Type 2 deiodinase (D2), which is highly expressed in brown adipose tissue (BAT), is an enzyme that amplifies thyroid hormone signaling in individual cells. Mice with inactivation of the D2 pathway (D2KO) exhibit dramatically impaired thermogenesis in BAT, leading to hypothermia during cold exposure and a greater susceptibility to diet-induced obesity. This was interpreted as a result of defective acute activation of BAT D2. Here we report that the adult D2KO BAT has a permanent thermogenic defect that stems from impaired embryonic BAT development. D2KO embryos have normal serum T3 but due to lack of D2-generated T3 in BAT, this tissue exhibits decreased ...

Altered glucose metabolism in the heart is an important characteristic of cardiovascular and metabolic disease. Because thyroid hormones have major effects on peripheral metabolism, we examined the metabolic effects of heart-selective increase in T3 using transgenic mice expressing human type 2 iodothyronine deiodinase (D2) under the control of the alpha-myosin heavy chain promoter (MHC-D2). Hyperinsulinemic-euglycemic clamps showed normal whole-body glucose disposal but increased hepatic insulin action in MHC-D2 mice as compared to wild-type (WT) littermates. Insulin-stimulated glucose uptake in heart was not altered, but basal myocardial glucose metabolism was increased by more than two-fold in MHC-D2 mice. Myocardial lipid levels were also elevated in MHC-D2 mice, suggesting an overall up-regulation of cardiac metabolism in these mice. The effects of doxorubicin (DOX) treatment on cardiac function and structure were examined using M-mode echocardiography. DOX treatment caused a significant reduction

The most conclusive evidence for using thyroid peroxidase antibody (TPO) is predictive in nature when evaluating possible subclinical hypothyroidism. If this test is positive, hypothyroidism occurs at a rate of 4.3% per year versus 2.6% per year when the antibody is negative. While this scenario does not cover all clinical indications for ordering TPO, there is no definitive evidence that repeat TPO testing provides additional information.1. Based on this information the ordering of TPO within Spectrum Health is being modified. If the test is ordered more than once on a patient, a screen will appear in EPIC indicating the following: This test should typically only be resulted once per lifetime.

Thyroid status is one of the most potent regulators of peripheral thyroid hormone metabolism in vertebrates. Despite this, the few papers that have been published concerning the role of thyroid hormones in the regulation of thyroid function in fish often offer conflicting data. We therefore set out to investigate the effects of tetraiodothyronine (thyroxine) (T4) or tri-iodothyronine (T3) supplementation (48 p.p.m.) via the food on plasma and tissue thyroid hormone levels as well as iodothyronine deiodinase (D) activities in the Nile tilapia (Oreochromis niloticus). T4 supplementation did not induce a hyperthyroid state and subsequently had no effects on the thyroid hormone parameters measured, with the liver as the sole notable exception. In T4-fed tilapias, the hepatic T4 levels increased substantially, and this was accompanied by an increase in in vitro type I deiodinase (D1) activity. Although the lack of effect of T4 supplementation could be partially explained by an inefficient uptake of T4 from

TY - JOUR. T1 - Human myeloperoxidase and thyroid peroxidase, two enzymes with separate and distinct physiological functions, are evolutionarily related members of the same gene family. AU - Kimura, Shioko. AU - Ikeda-Saito, Masao. PY - 1988/1/1. Y1 - 1988/1/1. N2 - Human myeloperoxidase and human thyroid peroxidase nucleotide and amino acid sequences were compared. The global similarities of the nucleotide and amino acid sequences are 46% and 44%, respectively. These similarities are most evident within the coding sequence, especially that encoding the myeloperoxidase functional subunits. These results clearly indicate that myeloperoxidase and thyroid peroxidase are members of the same gene family and diverged from a common ancestral gene. The residues at 416 in myeloperoxidase and 407 in thyroid peroxidase were estimated as possible candidates for the proximal histidine residues that link to the iron centers of the enzymes. The primary structures around these histidine residues were compared ...

This blood test is a combination test used to evaluate both, Thyroid Autoantibodies (TAA) and Thyroid Peroxidase Antibodies (TPO ab). Thyroid autoantibody (TAA) is a test that helps to determine if an autoimmune process is manifesting in the thyroid system. Autoantibodies to thyroglobulin (thyroid hormone) may lead to the destruction of the thyroid gland. Antibodies are more likely to appear after trauma or inflammation of the thyroid gland. Thyroid Peroxidase antibodies (TPO ab) is an important antibody test related to the thyroid gland because thyroid peroxidase is the enzyme responsible for the production of thyroid hormones. This enzyme plays a central role in the function of the thyroid gland. Thyroid peroxidase assists the chemical reaction that adds iodine to a protein called thyroglobulin, a critical step in generating thyroid hormones. Thyroid hormones play an important role in regulating growth, brain development, and the rate of chemical reactions in the body (metabolism ...

Objective: Genetic susceptibility to autoantibody formation in association with autoimmune thyroid disease and type 1 diabetes mellitus has been described with varying frequencies. We have, therefore, investigated the prevalence of anti-thyroid peroxidase (anti-TPO), overt and subclinical hypothyroidism in type 1 diabetic patients.. Methods: Sixty-five subjects with type 1 diabetes mellitus and 65 unrelated normal controls were recruited for the detection of anti-TPO and Thyroid-stimulating hormone (TSH). Written informed consent was obtained after the procedure had been fully explained.. Results: Among 65 type 1 diabetic patients, 18 (27.7%) were positive for anti-TPO and 18 (27.7%) had abnormal serum TSH level. Among these patients 11 (16.0%) had overt hypothyroidism and 7 (10.8%) had subclinical hypothyroidism. Compared with those without thyroid autoimmunity, there was a female preponderance for the type 1 diabetic patients with thyroid autoimmunity (female:male, 24:23 vs 11:7 respectively). ...

Antonio C. Bianco, MD, PhD is a professor of medicine and Chief of the Division of Endocrinology, Diabetes and Metabolism at the University of Miami Miller School of Medicine. Dr. Bianco obtained his M.D., PhD and clinical training in internal medicine and endocrinology in Sao Paulo, Brazil. Dr. Bianco is recognized as an authority in thyroid hormone metabolism and action, and his work has established the importance of the local control of thyroid hormone activation/inactivation via deiodination, as well as fundamental cellular and molecular properties of the deiodinases (D1, D2 and D3). Dr. Biancos work has helped elucidate the three-dimensional structure of the deiodinase-ubiquitination complex, demonstrating that hedgehog-mediated ubiquidation-deubiquidation controls local T3 production by affecting D2 dimerization. This constitutes a posttranslational on/off switch controlling thyroid hormone action in the settings of development, health and disease.. 2002 ATA Grant ...

Iodine deficiency induces multiple intrathyroidal autoregulatory changes leading to an increased triiodothyronine (T(3)) production and secretion, at the expense of thyroxine (T(4)). It is characterized by low serum T(4), normal or slightly elevated T(3), and as a consequence of the latter, normal thyrotropin (TSH). Tissues are also hypothyroxinemic, but their T(3) concentrations are mostly normal and ensure clinical euthyroidism, except for those that depend to a high degree on local generation from T(4) by extrathyroidal mechanisms involving the iodothyronine deiodinases isoenzymes. Thus, unless iodine deficiency is so severe and chronic that intrathyroidal and extrathyroidal mechanisms are no longer sufficient to maintain a normal T(3) in most tissues, individuals are clinically and biochemically euthyroid, but some tissues may be selectively hypothyroid (i.e., the brain). In adults both the intrathyroidal and the extrathyroidal mechanisms reacting to the iodine deficiency are fully operative ...

Type I-iodothyronine monodeiodinase (type I-MD) is abundant in thyroid tissue and contributes to the generation of T3 secreted by the gland. The availability of a specific antibody against rat type I-MD (type I-MD Ab) allowed us to directly identify this enzyme in rat thyroid glands, and in a differentiated strain of rat thyroid cells maintained in continuous culture (FRTL-5 cells). FRTL-5 cells maintain many differentiated functions of thyroid cells, including the expression of TSH receptor and thyroid peroxidase. Using an immunohistochemical technique on rat thyroid sections, a clear staining for type I-MD was demonstrated in follicular cells. The degree of immunoreactivity was greater in small follicles containing little amounts of colloid compared to large follicles lined by functionally inactive cells. Using immunofluorescence (IFL), a strong staining for type I-MD was observed in FRTL-5 cells grown in medium containing TSH. Both in vivo and in culture the staining for type I-MD was ...

TTF-1, a homeodomain-containing transcription factor, which is required for the specific expression of the thyroglobulin and thyroperoxidase gene promoters in differentiated thyroid cell lines, is expressed at the very beginning of rat thyroid differentiation. TTF-1 mRNA is detected in the endodermal cells of the thyroid rudiment in the rat embryo and precedes the expression of the two known target genes by 5 days. No delay is observed between the appearance of TTF-1 mRNA and protein, which shows a clear nuclear localization. In the adult thyroid, TTF-1 is present only in the endoderm-derived follicular cells. Two additional domains of expression of TTF-1 have been observed, the lung and restricted areas of the brain. In the lung, TTF-1 mRNA and protein are also present at the earliest stages of differentiation and are later confined to the bronchial epithelium. In the brain, TTF-1 appears to be restricted to structures of diencephalic origin, including the developing neurohypophysis. The early ...

Next to deiodination, glucuronidation and sulfation of the phenolic hydroxyl group are important pathways of iodothyronine metabolism. Although in general conjugation serves to facilitate the urinary and biliary excretion of lipophilic substances, sulfation of thyroid hormones has another important function. Sulfation protects the tissues against an excess of active thyroid hormone and it can also be used as a reservoir from which active hormone is released by sulfatases when and where it is required. Interaction between sulfation and deiodination has already been described in several mammalian tissues. After an initial characterization of the sulfotransferases we determined the changes in sulfation during chicken embryonic development and induced metamorphosis of the axolotl, a neotenous amphibian. Sulfation assays demonstrate the presence of sulfotransferases in liver, kidney and brain cytosol in one-day-old chicken. Similar to the situation in mammals, the enzyme(s) show a substrate preference for 3

AU - Tomaselli, Gordon F.. PY - 2003/9/1. Y1 - 2003/9/1. N2 - In contrast to fast inactivation, the molecular basis of sodium (Na) channel slow inactivation is poorly understood. It has been suggested that structural rearrangements in the outer pore mediate slow inactivation of Na channels similar to C-type inactivation in potassium (K) channels. We probed the role of the outer ring of charge in inactivation gating by paired cysteine mutagenesis in the rat skeletal muscle Na channel (rNav1.4). The outer charged ring residues were substituted with cysteine, paired with cysteine mutants at other positions in the external pore, and coexpressed with rat brain β 1 in Xenopus oocytes. Dithiolthreitol (DTT) markedly increased the current in E403C+E758C double mutant, indicating the spontaneous formation of a disulfide ...

This gene encodes a member of the G protein-coupled receptor (GPCR) superfamily. This protein functions as a cell surface receptor for bile acids. Treatment of cells expressing this GPCR with bile acids induces the production of intracellular cAMP, activation of a MAP kinase signaling pathway, and internalization of the receptor. The receptor is implicated in the suppression of macrophage functions and regulation of energy homeostasis by bile acids.[2] One effect of this receptor is to activate deiodinases which convert the prohormone thyroxine (T4) to the active hormone triiodothyronine (T3). T3 in turn activates the thyroid hormone receptor which increases metabolic rate.[3][4] ...

Objective: The aim of this study was to evaluate the presence of thyroid autoantibodies in patients with fibromyalgia (FM) and rheumatoid arthritis (RA) and to investigate the relationship of these antibodies with depression, quality of life, and disease symptoms..

Serumfree thyroxine, free triiodothyronine, thyrotropin, and anti-thyroglobulin (TgAb) and anti-thyroid peroxidase antibodies (TPOAb) were measured by immunometric assay. Sociodemographic characteristics, alcohol use, smoking status, morning stiffness, number of joints affected by pain, and presence of accompanying symptoms were recorded. All patients were questioned about the severity of pain, sleep disturbances, fatigue, and morning fatigue. The Fibromyalgia Impact Questionnaire (FIQ) was used to evaluate the quality of life and Beck Depression Inventory (BDI) was used to evaluate the presence of ...

Our work shows a link between anti-TPO antibodies and placental abruption, but that does not necessarily mean that thyroid supplementation would improve the health of the women or babies, said Dr. Brian Casey, professor of obstetrics and gynecology at UT Southwestern and the studys co-lead author.. The thyroid, a small butterfly-shaped gland at the base of the throat, produces hormones that regulate many of the bodys metabolic functions. Thyroid disorders can disrupt sleep, mood and mental sharpness, and cause weight gain or loss.. The thyroid uses an enzyme called thyroid peroxidase (TPO) to incorporate iodine into thyroid hormones. Table salt often contains added iodine so people can produce adequate levels of thyroid hormones.. TPO function is disrupted in some autoimmune diseases, when the body creates antibodies against it. As a result, hormone levels decrease and the bodys metabolism slows. But when antibody levels are still low, the thyroid can sometimes compensate and produce normal ...

by Werner Vosloo , Aug 16, 2011 , Auto-Immune, New, Thyroid Health. BACKGROUND: Hashimotos thyroiditis (HT) is a common disease, and is the most prevalent cause of hypothyroidism. Symptoms and diseases associated with HT are considered to be caused by hypothyroidism. We hypothesized that higher antithyroperoxidase (anti-TPO) antibody levels would be associated with an increased symptom load and a decreased quality of life in a female euthyroid patient collective.. METHODS: In a prospective cohort study 426 consecutive euthyroid female patients undergoing thyroid surgery for benign thyroid disease were included. Main outcome measures were preoperative anti-TPO levels, a symptom questionnaire and the SF-36 questionnaire, and lymphocytic infiltration of the thyroid tissue as evaluated by histology.. RESULTS: Histology revealed HT in 28/426 (6.6%) subjects. To maximize the sum of the predictive values, a cut-off point for anti-TPO of 121.0 IU/mL was calculated (sensitivity 93.3% [95% ...

Mainstream medicine considers a person has hypothyroidism when their TSH is above 4.5. However, many people are suffering many of the symptoms of hypothyroidism without having their TSH above 4.5. A more thorough Functional Medicine approach considers a more complete look at the pituitary and thyroid hormones regulating the thyroid. A full thyroid panel should include TSH, total T4, free T4, total T3, free T3, reverse T3, and thyroperoxidase antibodies and thyroglobulin antibodies.

This important gland has often been described as the mother of all glands because of the vast range of vital body functions orchestrated by the hormones it secretes.. Classified as an endocrine gland, like the parathyroid glands, adrenals, pancreatic and pituitry glands, it produces, stores and secretes specialized hormones into the blood stream, which in turn play a positive role in the support of life sustaining functions of several organs within the human body.. The key thyroid hormones produced and released into the blood stream are triiodothyronine (T3) and thyroxine (T4), with T3 being the biologically active hormone, following its conversion from T4 in the peripheral tissues by a process called deiodination of thyroxine. ( 1 ). The healthy active thyroid will produce 4 times more T4 than T3 (Roughly 80% T4 and 20% T3, ) and then convert the T4 into T3 for uptake in the various organ cells for energy production. Further transformations to T1 and T2 may occur in the peripheral ...

Battery-powered devices could soon be a thing of the past thanks to a group of UK researchers who have created a novel energy harvester to power some of the latest wearable gadgets.. By strapping the energy harvester to the knee joint, a user could power body-monitoring devices such as heart rate monitors, pedometers and accelerometers by simply walking and not have the worry of running out of power and replacing batteries. Soldiers may find this device particularly useful as they often have to carry up to 10kg of power equipment when on foot patrol.. The device was presented June 15 in IOP Publishings journal Smart Materials and Structures by researchers from Cranfield University, the University of Liverpool and University of Salford.. The energy harvesting device, which is designed to fit onto the outside of the knee, is circular and consists of an outer ring and central hub. The outer ring rotates as the knee joint goes through a walking motion. The outer ring is fitted with 72 plectra which ...

RESULTS HbA1c was significantly higher in TPO-Ab+ women than in those who were TPO-Ab− during the second (P , 0.01) and third (P , 0.05) trimesters. HbA1c levels significantly decreased in TPO-Ab− patients when the second (P , 0.01) and third (P , 0.05) trimesters were compared with before the pregnancy and the first trimester. There was a significant increase in the dosage of insulin for TPO-Ab+ versus TPO-Ab− patients during the second (P , 0.05) and third (P , 0.01) trimesters and 3 months postpartum (P , 0.05). TSH was significantly increased in the second (P , 0.001) and third (P , 0.05) trimesters and 3 months postpartum (P , 0.01) when compared with TPO-Ab− patients; 7.6% of the TPO-Ab− group and 29% in the TPO-Ab+ group presented postpartum thyroid dysfunction, and 42% of the TPO-Ab+ women required thyroid treatment.. ...

The phrase how to lose weight and how to lose belly fat are among the top 10 searched phrases on Google. Despite this there are more overweight people and obese than ever before in history. When we talk about how to lose weight, we are talking about some form of dietary restriction and perhaps to increase physical activity. There are many programs available some of them certainly are more effective than others, but the problem really lies with us. We are all looking for that magic pill, that magic program or that effortless diet that will make us thin and trim with the bare minimum of effort. Since such programs do not exist, obesity is epidemic. So, let us consider how we might design a program to lose belly fat and overall to lose weight the most effective way possible.. In addition to dietary restrictions there are many nutrients that can help with weight loss in several different ways. The first way is to lower blood sugar and insulin levels in the overweight and obese. It is excess ...

Vertebrate embryos are exposed to maternal hormones that can profoundly affect their later phenotype. Although it is known that the embryo can metabolize these maternal hormones, the metabolic outcomes, their quantitative dynamics and timing are poorly understood. Moreover, it is unknown whether embryos can adjust their metabolic activity to, for example, hormones or other maternal signals. We studied the dynamics of maternal steroids in fertilized and unfertilized rock pigeon eggs during early incubation. Embryos of this species are naturally exposed to different amounts of maternal steroids in the egg according to their laying position, which provides a natural context to study differential embryonic regulation of the maternal signals. We used mass spectrometric analyses to map changes in the androgen and estrogen pathways of conversion. We show that the active hormones are heavily metabolized only in fertilized eggs, with a corresponding increase in supposedly less potent metabolites already ...
