Figure 2: The Effects of Endogenous Thyroglobulin Antibody on the Measurement of Serum Thyroglobulin using Immunoenzymatic (Sandwich) Method. Thyroglobulin Immunoassays. Several immunoassays are commercially available to measure thyroglobulin including the competitive radioimmunoassay (RIA) and the one-step immunoenzymatic (sandwich) assay (IMA). The RIA method is older and more labor intensive compared to IMA. In the RIA method, thyroglobulin competes with 125I labeled human thyroglobulin for a rabbit antibody against human thyroglobulin. After six days of incubation, thyroglobulin - antibody complexes are precipitated with a second anti-rabbit antibody. This method can detect both free thyroglobulin and thyroglobulin bound to antibody. The radioactivity is inversely proportional to the thyroglobulin concentration (2). In contrast to RIA, the IMA can be performed within one hour. The thyroglobulin in the patients sample is mixed with a biotinylated reagent that contains four monoclonal ...

TY - JOUR. T1 - Splitting of human thyroglobulin. III. Comparison of fragments obtained during enzymatic digestion and by reduction and alkylation. AU - Mehta, P. D.. AU - Rose, N. R.. PY - 1974/1/1. Y1 - 1974/1/1. N2 - Purified thyroglobulin was digested with trypsin and papain and was also reduced with dithiothreitol and alkylated with iodoacetamide. The resulting fragments were separated and characterized by immunological techniques. Following enzymatic degradation a small fragment, termed fraction 2, was isolated. It had a sedimentation coefficient of approximately 3S and a mol. wt determined by SDS polyacrylamide gel electrophoresis of approximately 37,000. In the Ouchterlony test, it was antigenically deficient as compared with intact thyroglobulin, when rabbit antisera to human thyroglobulin were used. With human autoantisera, fraction 2 did not show any precipitin reaction in the Ouchterlony test. However, it produced weak inhibition in the tanned cell haemagglutination test. The ...

Highly purified toxin A of Clostridium difficile was obtained by bovine thyroglobulin affinity chromatography followed by two sequential anion-exchange chromatography steps on Q Sepharose FF and Mono Q. After Q Sepharose FF chromatography of a thyroglobulin affinity-purified toxin A preparation, two major peaks of cytotoxicity representing toxins A and B were detected. The homogeneity of the final toxin A preparation obtained from Mono Q anion-exchange fast protein liquid chromatography was ascertained by gel electrophoresis developed by silver stain. The mol. wt of toxin A in non-denaturing conditions was estimated to be 520-540 Kda by native polyacrylamide gel electrophoresis (PAGE) developed by silver stain. In contrast, with sodium dodecyl sulphate (SDS)-PAGE under reducing or non-reducing conditions, a major band of 240 Kda and 10 minor and 27 faint bands (non-reduced conditions), or four minor and 31 faint bands (reduced conditions) were detected after silver staining. In two-dimensional PAGE, the

Combined preoperative serum thyroglobulin level and ACR-thyroid imaging reporting and data system scoring could accurately define malignant thyroid nodules

Spencer C , Petrovic I , Fatemi S. J Clin Endocrinol Metab. 2011 May;96(5):1283-91.. Specimens have thyroglobulin antibody (TgAb) measured prior to thyroglobulin (Tg) testing because the qualitative TgAb status (positive or negative) determines risk for Tg assay interference, and the quantitative TgAb concentration serves as a surrogate tumor marker for differentiated thyroid cancer. This study assessed the reliability of four TgAb methods to detect interfering TgAb [as judged from abnormally low Tg immunometric assay (IMA) to Tg RIA ratios] and determine whether between-method conversion factors might prevent a change in method from disrupting TgAb monitoring. Sera from selected and unselected TgAb-negative and TgAb-positive differentiated thyroid cancer patients had serum Tg measured by both IMA and RIA and TgAb measured by a reference method and three additional methods.: The Tg IMA and Tg RIA values were concordant when TgAb was absent. Tg IMA to Tg RIA ratios below 75% were considered to ...

Dyshormonogenesis due to thyroglobulin (TG) gene mutations is a rare cause of congenital hypothyroidism with an estimated incidence of approximately 1 in 100,000 newborns. The TG gene is organized in 48 exons, spanning over 270 kb on human chromosome 8q24. The human TG mRNA is 8.5 Kb long and the preprotein monomer is composed of a 19 amino acids signal peptide followed by a 2749 residues polypeptide. Until now, one hundred seventeen deleterious mutations in the human TG gene have been identifi ed and characterized, originating structural changes in the protein that alter the normal protein folding, assembly and biosynthesis of thyroid hormones: 19 splice site mutations, 23 nonsense mutations, 57 missense mutations, 13 deletions (9 single nucleotide deletions, 2 multiple nucleotide deletions and 2 involving a large number of nucleotides), 4 single nucleotide insertions or duplication and 1 imperfect DNA inversion. The p.R277*, p.R1511*, p.A2215D, p.R2223H and p.R2317* mutations are the most ...

N2 - Experimental evidence suggests that in autoimmune thyroid diseases (AITDs) the skin is a target of autoantibodies against thyroid-specific antigens; however, the role of these autoantibodies in skin alterations remains unclear. To gain insight into the function of nominally thyroid-specific genes in skin, we analyzed the expression of thyroid-stimulating hormone-receptor (TSH-R), thyroglobulin (Tg), sodium iodide symporter (NIS), and thyroperoxidase (TPO) genes in normal human skin biopsies and cultured primary keratinocytes and dermal fibroblasts. The results revealed the presence of all the transcripts in skin biopsies. ...

[online]. 2011, vol.49, n.3, pp.118-122. ISSN 2078-5151.. BACKGROUND: Thyroglobulin (Tg) is used as a postoperative marker for the follow-up of patients with thyroid carcinoma, but there is no consensus regarding the value that may indicate possible recurrence. AIM: To evaluate Tg levels as a marker for recurrence of thyroid carcinoma. SUBJECTS AND METHODS: Demographics and survival of 80 patients who underwent total thyroidectomy for well-differentiated thyroid cancer were analysed and related to Tg levels. Tg measurements were performed when patients were euthyroid, after completion of treatment. RESULTS: The median Tg value was 1.3 ng/ml. Higher values were found in males, high-risk patients and patients with recurrent disease. Using the median Tg value as ...

Describes when a thyroglobulin test is ordered, how a thyroglobulin test is used, and what the results of a thyroglobulin test might mean

A thyroid test should be something done regularly. Autoimmunity can be detected due to the increased antibodies found in blood, and comparing them with those that are found within the thyroid glands. This can effectively tell whether the thyroid is under attack by ones own immune system. In associations with Hashimotos, thyroglobulin and thyroid peroxidase antibodies are the most pronounced.. The TPO/TG antibodies test can be used to diagnose both Graves antibodies and TSH receptor antibodies. This test can detect minute increase in the number of antibodies even before there is visible change in the amount of TSH. The difference in the two conditions should be adequately expounded by ones GP.. Hashimotos usually develops as a result of increased release of thyroid peroxidase antibodies and thyroglobulin antibodies above 35 in each.. Having these antibodies elevated beyond 35 predisposes one to develop hypothyroidism before the end of a decade. Information on the level of thyroid antibodies ...

so, lets talk about thyroid medication dosing. there are several reasons that this is important. it is extremely important to keep the TSH at a level to suppress the possible stimulation of thyroglobulin. just as a reminder, only thyroid cells produce thyroglobulin. if you do not have a thyroid gland in your body, and you test positive for the presence of thyroglobulin( this should be part of your blood work test), that means that you have, most likely, thyroid cancer cells somewhere else in your body. unfortunately, there is also another factor that adds to the excitement, and that is that some people ( me included) produce thyroglobulin antibodies. this makes the test for thyroglobulin rather difficult to interpret. in my case, i tested positive for the thyroglobulin( TG) the first year, as well as the antibodies. for the next two and a half years, i tested positive for just the antibodies. my physician could not explain the why to me, and it was very stressful. after a little over three ...

Background Increased levels of thyroglobulin (Tg) and thyroid-stimulating hormone (TSH) are associated with differentiated thyroid carcinoma (TC) risk, but strong epidemiological evidence is lacking. Methods Three hundred fifty-seven incident TC case patients (n = 300 women and 57 men; mean age at blood collection = 51.5 years) were identified in the EPIC cohort study and matched with 2 (women) or 3 (men) control subjects using incidence density sampling. Matching included study center, sex, age, date, time, and fasting status at blood collection. Levels of total and free (f) thyroxine (T4) and triiodo-thyronine (T3), TSH, Tg, and anti-Tg antibodies (TgAb) were measured by commercially available immunoassays. Odds ratios (ORs) and 95% confidence intervals (CIs) were computed using conditional logistic regression. All statistical tests were two-sided. Results TC risk was positively associated with Tg (OR for the highest vs lowest quartile = 9.15; 95% CI = 5.28 to 15.90; P , .001) and negatively ...

Iodine is an essential element required for the function of all organ systems. Although the importance of iodine in thyroid hormone synthesis and reproduction is well known, its direct effects on the immune system are elusive. Human leukocytes expressed mRNA of iodide transporters (NIS and PENDRIN) and thyroid-related proteins [thyroglobulin (TG) and thyroid peroxidase (TPO)]. The mRNA levels of PENDRIN and TPO were increased whereas TG transcripts were decreased post leukocyte activation. Flow cytometric analysis revealed that both PENDRIN and NIS were expressed on the surface of leukocyte subsets with the highest expression occurring on monocytes and granulocytes. Treatment of leukocytes with sodium iodide (NaI) resulted in significant changes in immunity-related transcriptome with an emphasis on increased chemokine expression as probed with targeted RNASeq. Similarly, treatment of leukocytes with NaI or Lugols iodine induced increased protein production of both pro- and anti-inflammatory cytokines.

Papillary thyroid carcinoma (PTC) is one type of thyroid cancer and accounts for about 80% of the cases. Routine surveillance by serum thyroglobulin (Tg) and medical imaging is the current practice to monitor disease progression of the patients. However, the presence of anti-Tg antibody or other influence factors may discount the value of serum Tg in disease monitoring. Whether enumeration of circulating epithelial cells (CECs) and its combined analyses with serum Tg help to define disease status of PTC patients was investigated. CECs were first enriched from the peripheral blood of the healthy control subjects (G1, n = 17) and the patients at disease-free status (G2, n = 26) or with distant metastasis (G3, n = 22). The number of CECs expressing epithelial cell adhesion molecule (EpCAM) was determined by immunofluorescence microscopy analyses. The medium number of EpCAM+-CECs was 6 (intequartile range 1-11), 12 (interquartile range 7-16) and 91 (interquartile range 31-206) cells/ml of blood for ...

She told me shes ambivalent about biopsying and cherry-picking, as she calls it. What she calls cherry-picking is going through my neck to biopsy and (eventually) surgically remove any lymph nodes that show any level of cancer, no matter how small.

This has been her decision the last three years, so Im not completely shocked. This time around, though, she is unsure if she wants to do a stimulated thyroglobulin test. A stimulated thyroglobulin means that the patient receives shots of thyrogen (right above the butt - Yay!) and at the end of the week, gets more blood work done to compare to the initial unstimulated thyroglobulin. If the numbers are higher, it means there is thyroid cancer still in the body. This test is much more sensitive in finding any leftover or recurrent cancer cells. When my numbers come back from this test and if they ...

The homopurine–homopyrimidine DNA sequence flanking the thyroglobulin gene does not behave as a transcriptional diode in living cells Christiane Christophe-Hobertus, Daniel ChristopheInstitut de Recherche Interdisciplinaire en Biologie Humaine et Moléculaire (IRIBHM), Institut de Biologie et de Médecine Moléculaires (IBMM), Faculté de Médecine, Université Libre de Bruxelles, Gosselies, Belgium Abstract: Homopurine–homopyrimidine DNA sequences are found at higher than expected frequency around gene promoters in mammalian genomes. They were reported to act as a transcriptional diode in in vitro assays, as only the homopurine DNA strand was transcribed. We show here that the homopurine–homopyrimidine upstream element of the thyroglobulin gene promoter is able to reduce transcription initiated from different promoters, both on transiently transfected plasmids or when integrated into the genome of rat thyroid cells.

Experimental autoimmune thyroiditis (EAT) is a model for Hashimotos thyroiditis which is characterized by mononuclear cell infiltration and follicular destruction. We previously reported on an Eα-transgenic strain (H2A−E+) that is highly susceptible to human (h) thyroglobulin (Tg)-induced EAT, but strongly tolerant to mouse (m)Tg. After mTg and adjuvant, traditional, resistant strains do not develop thyroiditis, nor detectable primed T cell proliferation, but do make anti-mTg Abs. By contrast, this H2Eb+ strain does not even produce mTg Abs. To identify what epitopes in the mouse thyroid hTg-primed, thyroiditogenic T cells recognize to evoke EAT, we first confirmed that hTg-primed cells do not respond to mTg, nor to other thyroid Ags. We next selected the three immunogenic epitopes on hTg known to be processed and presented by H2Eb, as the basis for synthesizing potential mTg epitopes. One 15-mer peptide, mTg409, did prime T cells, elicit Ab, and generate moderate thyroiditis. Thyroiditis ...

Genetically susceptible mice become resistant to experimental autoimmune thyroiditis (EAT) induction with mouse thyroglobulin (MTg) and lipopolysaccharide after pretreatment with deaggregated MTg (dMTg). Recent work showed this suppression to be mediated by CD4+ suppressor T cells (Ts). To study Ts action in vivo, we used a rat IgG2a monoclonal antibody (mAb), YTS 177.9, which modulates CD4 antigen in vivo without depleting CD4+ cells. Initial studies showed that after two 1-mg doses of mAb 7 days apart, extensive CD4 antigen modulation of peripheral blood leukocytes occurred within 4 days. Mice given CD4 mAb 24 hr before dMTg (2 doses, 7 days apart) were resistant to EAT induction when immunized with MTg and LPS 20 days later. Also, anti-rat IgG2a titers were reduced following challenge with heat-aggregated rat IgG2a compared to controls. Subsequent analysis of serum in CD4 mAb-treated animals revealed that mAb was present in the circulation for 14 days. Moreover, mice given CD4 mAb and dMTg, then

The thyroid gland is a small endocrine gland located in the base of the neck. It consists of two lateral lobes connected by an isthmus. The gland produces a variety of metabolic hormones in a negative biofeedback loop.. Thyroglobulin (Tg) is a large glycoprotein (MW 600,000) that is stored in the follicular colloid of the gland. Thyroglobulin functions as aprohormone in the intra-thyroid synthesis of T4 and T3. Lysosomes containing proteases cleave T4 and T3 from Tg, resulting in release of these hormones.. Thyroglobulin is present in the serum of normal healthy individuals and can be elevated in numerous disorders which disrupt thyroid tissue. Elevated circulating levels of Tg have been found in a number of thyroid Conditions including Hashimotos disease, Graves disease. Thyroid Adenoma, sub acute thyroiditis and thyroid carcinoma1.. Thyroid cancer is a relatively common form of cancer. It is not generally malignant, and normal life span can be obtained with appropriate follow-up and ...

AIM: The aim of this study was to evaluate the role of 18F fluorodeoxyglucose-positron emission tomography (FDG-PET), differentiated thyroid carcinoma (DTC) treated with therapeutic (131)I because of elevated thyroglobulin (Tg) levels during follow up. The results of FDG-PET/CT were compared with post-therapy (131)I whole body scan (131I-t-WBS) and Tg at short term follow up.. METHODS: Forty-five patients with DTC underwent a new therapeutic (131I) administration based upon Tg values ,1.5 ng/mL. All patients underwent (131I-t-WBS) 5-7 days after 131I therapy. A few days before 131I administration, a FDG-PET scan was performed in all patients. FDG-PET/CT was considered positive (PET+) when at least one abnormal focus of FDG uptake was found; likewise, 131I-t-WBS was considered positive(WBS+) when at least on abnormal focus of uptake was found. Assessment of short-term response to radioiodine was performed by measuring Tg values.. RESULTS: FDG-PET/CT was positive in 32 patients, 23 of which had ...

The post-therapeutic WBS was performed on the third day after administrating 30 mCi radioiodine (I-131) in the sixth week after total thyroidectomy. Pretreatment was as follows: the patients underwent thyroid hormone withdrawal to increase the radioiodine uptake in residual thyroid tissue. Thyroxine was discontinued 4 weeks before ablation. Instead of thyroxine, triiodothyroxine (20 µg) was given orally twice a day for 2 weeks.Triiodothyroxine was withdrawn, and the patients were instructed to follow a low-iodine diet for 2 weeks before ablation. Before I-131 administration, serum thyroid stimulating hormone (TSH), free T4, T3, TSH-stimulating thyroglobulin (Tg; reference, 1.4 to 78.0 ng/mL), and antithyroglobulin antibody (anti-Tg Ab, negative ,100 IU/mL) were measured [27]. For all patients, TSH increased to above 30 mU/L after thyroid hormone withdrawal [27]. Diagnostic WBS was performed at 6 to 12 months after radioiodine thyroid ablation. The 3 mCi dose was administered 3 days prior to ...

Context: Thyroglobulin (TG) gene mutations cause congenital hypothyroidism (CH) with goiter. A founder effect has been proposed for some frequent mutations. Mutated proteins have a defect in intracellular transport causing intracellular retention with ultrastructural changes that resemble an endoplasmic reticulum storage disease. Objective: To reveal new aspects of thyroglobulin pathophysiology through clinical, cellular, molecular, and genetic studies in a family presenting with CH due to TG mutations from Galicia, an iodine-deficient area of Spain. Design: The included clinical evaluation of family members,DNAsequencing for TG gene mutation and haplotyping analysis, ultrastructural analysis of thyroid tissue specimens from affected subjects, analysis of effects of mutations found on TG gene transcription, and in vitro studies of cellular production and secretion of mutated proteins. Setting: Locations included primary care and university hospitals. Results: Family members with CH, mental ...

The most common cause of canine thyroid disease is autoimmune thyroiditis (estimated 90% of cases). Thyroiditis is an immune-mediated process that develops in genetically susceptible individuals and is characterized by the presence of antithyroid antibodies in the blood or tissues. Thyroiditis is believed to start in most cases around puberty, and gradually progress through mid-life and old age to become clinically expressed hypothyroidism once thyroid glandular reserve has been depleted. During this process, the animal or person becomes more susceptible to immune-mediated or other diseases affecting various target tissues and organs. The prerequisite genetic basis for susceptibility to this disorder has been in established in humans, dogs and several other species.. About half of canine hypothyroidism has been reported to be associated with autoimmune thyroiditis (positive TgAA- Thyroglobulin Autoantibody); the majority of the remaining hypothyroidism is idiopathic (without apparent cause and ...

20 ng/ml) serum Tg levels and negative Anti TgAb. In 75 patients (8.4% of patients or 63% of the Tg+ve subgroup), elevated Tg levels correlated well with positive 131I imaging. In 13 patients with positive correlation Tg/131I WBS, WBS revealed pulmonary (12 pts) or bone (1 pt) metastases, with no uptake in the cervical region. Moreover, 45 patients (5% of all patients or 37.5% of the Tg+ve group) presented discordant elevated Tg levels and negative Anti TgAb but negative WBS imaging. Using the same immune-radiometric method, with optimal sensitivity for Tg and without reported Hook effect for Anti TgAb, we found in 9% of patients the presence of strong positive Anti Tg, interfering with the Tg assay and underestimating serum Tg levels. From 890 patients sera, in 79 % Anti TgAb were < 35 mUI/ml (negative value), 8 % were equivocal (35-65%) and 12 % were strongly positive ( >65 mUI/ml). Conclusions: Detectable or elevated Tg concentrations most often correlate with 131I uptake, allowing ...

Thyroglobulin releases TH by the action of lysosomal proteases inside the follicular cell. Colloid droplets then form on the apical surface of the cell via endocytosis, stimulated by TSH; finally, lysosomes release proteolytic enzymes which will in turn release TH. Considerable amounts of circulating thyroglobulin are only found when the thyroid cell has been damaged. Excess iodide inhibits the release of TH. The treatment of severe hyperthyroidism usually benefits from this effect.3 The TH released in the circulation will bind to carrier molecules: globulin (thyroxine-binding globulin - TBG); transthyretin (TTR), previously called prealbumin (thyroxine-binding prealbumin - TBPA); and albumin. TBG binds 70% of T4 and 80% of T3.6,7 Reverse T3 (rT3) derives from the peripheral monodeiodination of T4.. Mechanism of action of thyroid hormones Most part of the biological effects associated with TH are determined by interactions between T3 and their specific nuclear receptors. The binding of TH with ...

BACKGROUND: The carbohydrate alpha-gal epitope is present in many animal proteins, including those of red meat and animal immunoglobulins, such as cat IgA. Systemic anaphylaxis to the alpha-gal epitope has recently been described. OBJECTIVE: To investigate and compare the prevalence of alpha-gal-specific (s)IgE and its associated factors in the general adult population from two separated (Northern and Southern) European regions (Denmark and Spain, respectively). METHODS: Cross-sectional study of 2297 and 444 randomly selected adults from 11 municipalities in Denmark and one in Spain. Alpha-gal sIgE was assessed by ImmunoCAP to bovine thyroglobulin. Additional assessments included a panel of skin prick test (SPT) to common aeroallergens and epidemiological factors, including the history of tick bites in the Danish series. RESULTS: The prevalence of positive (≥ 0.1 kUA /L) sIgE to alpha-gal was 5.5% and 8.1% in the Danish and Spanish series, respectively. The prevalence of sIgE ≥ 0.35 kUA /L ...

Maturation of the rat fetal thyroid was studied with the aid of I131 and of fluorescence and electron microscopy. The I131 concentration of the fetal gland increased exponentially from day 17 to day 20 of gestation and was related to the weight of the fetus (and presumably the weight of the thyroid) and also to the quantity of I131 accumulated by the fetus. In the 17-day gland, thyroglobulin or immunologically similar material was sparsely present in the incipient lumens of some cell clusters. With maturation, this material increased and was also observed within follicular cells on days 18 to 19 of gestation. On day 20, the specifically reacting material was present in the follicular lumens and was absent from the cytoplasm of follicular epithelium. Ultrastructurally, the earliest thyroid cells examined were replete with all the organelles found in the more mature epithelium. No direct correlation could be made between the cytoplasmic structures and the presence of thyroglobulin, although the ...

In low-risk thyroid cancer treated with total thyroidectomy and radioiodine, sonography and suppressed or stimulated Tg have similar negative predictive values for persistence/recurrence. Importantly, the coexistence of negative sonographic findings and suppressed Tg lower than 1 ng/mL makes the addition of stimulated Tg unlikely to identify clinically important disease..

Treatment with a non-depleting monoclonal antibody to CD4 in the presence of mouse thyroglobulin (MTg) inhibits the development of murine autoimmune thyroiditis. This unresponsiveness was transferrable since such treatment generated a population of donor cells which could suppress the thyroiditis induced in lightly irradiated recipients by subsequent challenge with specific antigen. The suppression appears to be both antigen specific and antigen dependent and seems to discriminate between TH1 and TH2 helper subsets in that there is no significant effect on anti-MTg autoantibodies after challenge.

Amines, aminooxy (also known as oxylamine), hydrazide, azide, alkyne, BCN, and tyramide reactive dyes, as well as dye free acids, are generally stable in aqueous solution when stored at -20°C for 6-12 months or longer, as long as no compounds are present that may react with the dyes functional group. See the product information sheets for specific reactive dyes more information.. Coelenterazines and D-luciferin. Coelenterazines are stable in solid form when stored as recommended; they are not stable in aqueous solution. Concentrated coelenterazine stock solutions (typically 1-100 mg/mL) should be prepared in ethanol or methanol; do not use DMSO or DMF to dissolve coelenterazines, because these solvents will oxidize the compounds. Ethanol or methanol stocks of coelenterazine can be stored at -20°C or below for six months or longer; alcohol stocks may evaporate during storage, so use tightly sealing screw cap vials and wrap the vials with Parafilm for long term storage. Propylene glycol also ...

my son and daugher-in-law think that my husband and i did them a huge favor this weekend. they took their first vacation, or over-night trip away from their baby. they had a well deserved anniversary trip and i hope that they had a great time. actually, they did us a favor. we got to share in the happiness of a child, and it was a good reminder to appreciate all the little things, that, afterall, make life, life. i know that i have an ultrasound and blood work ( thyroglobulin/thyroglobulin ab) tests coming up in october. but until then, i am going to enjoy my life and try not to worry so much about tests. speaking of tests, i found out that i do not have to have a full body scan this year! no low iodine diet- yipee! although i would not mind the 10-15 pound weight loss that i always have when i go on it. my doctor relies on ultrasounds and blood work to check for any problems. any set backs as my grandmother used to say. i wonder what my grandson will remember about me? what i used to say or ...

The c.1588T,C (p.Tyr530His) missense variant in the SLC26A4 gene has been reported as a common deleterious variant associated with Pendred Syndrome (Coyle et al., 1998; Blons et al., 2004). This variant has been reported in several affected individuals, often in trans with a second deleterious variant (V138F, T410M, c.2089+1G,A, V422D, T416P, Y78C, F355S) (Blons et al., 2004; Banghova et al., 2008; Borck et al., 2009; Ladsous et al., 2014). Functional studies have shown this variant affects protein localization within the cell; additionally, some affected individuals harboring this variant have elevated thyroglobulin (Choi et al., 2009; Ladsous et al., 2014). This variant is reported at low frequency within the control population databases (Exome Sequencing Project [ESP] = NA; 1000 Genomes = NA; and ExAC = 0.002). Multiple in silico algorithms predict the variant to have a deleterious effect (GERP = 5.96; CADD = 26.2; PolyPhen = 1; SIFT = 0.02). In addition, reputable diagnostic laboratories ...

Stimulation of thyrocytes with thyroid stimulating hormone (TSH) leads to a morphological change and a massive increase in thyroglobulin (Tg) production. Although Tg is a demanding client of the endoplasmic reticulum (ER), its increase did not result in significant accumulation of unfolded protein in the ER. Instead, ER chaperones and ... read more folding enzymes reached maximum synthesis rates immediately after TSH stimulation, before significant upregulation of Tg synthesis. The resulting increase in folding capacity before client protein production prevented cellular unfolded-protein stress, confirmed by the silence of the most conserved branch of the unfolded protein response. Thyrocytes set an example of physiological adaptation of cells to a future potentially stress-causing situation, which suggests a general strategy for both non-secretory and specialized secretory cells show less ...

Thyroid epithelial cells secrete thyroglobulin (comprising 134 tyrosines) and iodine into colloid. Iodide transport is via a symport with sodium (NIS). Thyroid peroxidise makes iodotyrosines (MIT and DIT) then combines them to make T3 and T4. Some reverse T3 (inactive) also made. Endocytosis and lysis of colloid releases free hormone. All steps TSH controlled. T3 also made peripherally by deiodination of T4.. ...
