A glycoprotein hormone secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). Thyrotropin stimulates THYROID GLAND by increasing the iodide transport, synthesis and release of thyroid hormones (THYROXINE and TRIIODOTHYRONINE). Thyrotropin consists of two noncovalently linked subunits, alpha and beta. Within a species, the alpha subunit is common in the pituitary glycoprotein hormones (TSH; LUTEINIZING HORMONE and FSH), but the beta subunit is unique and confers its biological specificity.
A small circumscribed mass in the THYROID GLAND that can be of neoplastic growth or non-neoplastic abnormality. It lacks a well-defined capsule or glandular architecture. Thyroid nodules are often benign but can be malignant. The growth of nodules can lead to a multinodular goiter (GOITER, NODULAR).
The major hormone derived from the thyroid gland. Thyroxine is synthesized via the iodination of tyrosines (MONOIODOTYROSINE) and the coupling of iodotyrosines (DIIODOTYROSINE) in the THYROGLOBULIN. Thyroxine is released from thyroglobulin by proteolysis and secreted into the blood. Thyroxine is peripherally deiodinated to form TRIIODOTHYRONINE which exerts a broad spectrum of stimulatory effects on cell metabolism.

There was a concomitant, significant decrease in serum thyroxine and triiodothyronine values between September and October (thyroxine, 1.0+/-0.3 mug/100 ml and 0.4 mug/100 ml in September and October, respectively; triiodothyronine, 400.3+/-51.6 ng/100 ml and 80.2 ng/100 ml in September and October, respectively) and marked hypertrophy and hyperplasia of thyrotrophs. These data indicate a progressive hypothyroid condition which, although it may be linked to iodide deficiency, may well be enhanced by other environmental factors. The evidence for involvement of other factors is discussed.  (+info)

Characterization of an amphioxus paired box gene, AmphiPax2/5/8: developmental expression patterns in optic support cells, nephridium, thyroid-like structures and pharyngeal gill slits, but not in the midbrain-hindbrain boundary region. (2/4177)

On the basis of developmental gene expression, the vertebrate central nervous system comprises: a forebrain plus anterior midbrain, a midbrain-hindbrain boundary region (MHB) having organizer properties, and a rhombospinal domain. The vertebrate MHB is characterized by position, by organizer properties and by being the early site of action of Wnt1 and engrailed genes, and of genes of the Pax2/5/8 subfamily. Wada and others (Wada, H., Saiga, H., Satoh, N. and Holland, P. W. H. (1998) Development 125, 1113-1122) suggested that ascidian tunicates have a vertebrate-like MHB on the basis of ascidian Pax258 expression there. In another invertebrate chordate, amphioxus, comparable gene expression evidence for a vertebrate-like MHB is lacking. We, therefore, isolated and characterized AmphiPax2/5/8, the sole member of this subfamily in amphioxus. AmphiPax2/5/8 is initially expressed well back in the rhombospinal domain and not where a MHB would be expected. In contrast, most of the other expression domains of AmphiPax2/5/8 correspond to expression domains of vertebrate Pax2, Pax5 and Pax8 in structures that are probably homologous - support cells of the eye, nephridium, thyroid-like structures and pharyngeal gill slits; although AmphiPax2/5/8 is not transcribed in any structures that could be interpreted as homologues of vertebrate otic placodes or otic vesicles. In sum, the developmental expression of AmphiPax2/5/8 indicates that the amphioxus central nervous system lacks a MHB resembling the vertebrate isthmic region. Additional gene expression data for the developing ascidian and amphioxus nervous systems would help determine whether a MHB is a basal chordate character secondarily lost in amphioxus. The alternative is that the MHB is a vertebrate innovation.  (+info)

The paired-domain transcription factor Pax8 binds to the upstream enhancer of the rat sodium/iodide symporter gene and participates in both thyroid-specific and cyclic-AMP-dependent transcription. (3/4177)

The gene encoding the Na/I symporter (NIS) is expressed at high levels only in thyroid follicular cells, where its expression is regulated by the thyroid-stimulating hormone via the second messenger, cyclic AMP (cAMP). In this study, we demonstrate the presence of an enhancer that is located between nucleotides -2264 and -2495 in the 5'-flanking region of the NIS gene and that recapitulates the most relevant aspects of NIS regulation. When fused to either its own or a heterologous promoter, the NIS upstream enhancer, which we call NUE, stimulates transcription in a thyroid-specific and cAMP-dependent manner. The activity of NUE depends on the four most relevant sites, identified by mutational analysis. The thyroid-specific transcription factor Pax8 binds at two of these sites. Mutations that interfere with Pax8 binding also decrease transcriptional activity of the NUE. Furthermore, expression of Pax8 in nonthyroid cells results in transcriptional activation of NUE, strongly suggesting that the paired-domain protein Pax8 plays an important role in NUE activity. The NUE responds to cAMP in both protein kinase A-dependent and -independent manners, indicating that this enhancer could represent a novel type of cAMP responsive element. Such a cAMP response requires Pax8 but also depends on the integrity of a cAMP responsive element (CRE)-like sequence, thus suggesting a functional interaction between Pax8 and factors binding at the CRE-like site.  (+info)

Diverse developing mouse lineages exhibit high-level c-Myb expression in immature cells and loss of expression upon differentiation. (4/4177)

The c-myb gene encodes a sequence specific transactivator that is required for fetal hematopoiesis, but its potential role in other tissues is less clear because of the early fetal demise of mice with targeted deletions of the c-myb gene and incomplete of knowledge about c-myb's expression pattern. In the hematopoietic system, c-Myb protein acts on target genes whose expression is restricted to individual lineages, despite Myb's presence and role in multiple immature lineages. This suggests that c-Myb actions within different cell type-specific contexts are strongly affected by combinatorial interactions. To consider the possibility of similar c-Myb actions could extend into non-hematopoietic systems in other cell and tissue compartments, we characterized c-myb expression in developing and adult mice using in situ hybridization and correlated this with stage-specific differentiation and mitotic activity. Diverse tissues exhibited strong c-myb expression during development, notably tooth buds, the thyroid primordium, developing trachea and proximal branching airway epithelium, hair follicles, hematopoietic cells, and gastrointestinal crypt epithelial cells. The latter three of these all maintained high expression into adulthood, but with characteristic restriction to immature cell lineages prior to their terminal differentiation. In all sites, during fetal and adult stages, loss of c-Myb expression correlated strikingly with the initiation of terminal differentiation, but not the loss of mitotic activity. Based on these data, we hypothesize that c-Myb's function during cellular differentiation is both an activator of immature gene expression and a suppressor of terminal differentiation in diverse lineages.  (+info)

Measurement of serum TSH in the investigation of patients presenting with thyroid enlargement. (5/4177)

In otherwise euthyroid patients presenting with thyroid enlargement, reduction in serum thyrotrophin (TSH) concentrations measured in a sensitive assay may be a marker of thyroid autonomy and may therefore indicate a benign underlying pathology. We investigated prospectively a cohort of 467 subjects presenting consecutively to our thyroid clinic with nodular or diffuse enlargement of the thyroid. Subjects were divided into those with normal (0.4-5.5 mU/l), low but detectable (0.1-0.39 mU/l) or undetectable (< 0.1 mU/l) serum TSH concentrations. The final pathological diagnosis was defined by fine-needle aspiration cytology and clinical follow-up of at least 2 years or by fine-needle aspiration cytology and histology following surgical treatment. Serum TSH concentrations below normal were found in 75 patients (16.1%), those with low serum TSH results having higher mean free T4 concentrations, were older and were more likely to be female. In those with undetectable serum TSH, no patient had a diagnosis of thyroid neoplasia and in those with low but detectable TSH, thyroid neoplasms were diagnosed in two patients (3.4%). In those with normal serum TSH, 12.0% had a final diagnosis of thyroid neoplasm (p = 0.013). Overall, thyroid malignancy was found in one patient (1.3%) of those with a serum TSH measurement below the normal range and 6.9% of those with normal serum TSH (p < 0.06). Reduction in serum TSH at presentation may identify a group which requires less intensive investigation and follow-up than those without biochemical evidence of thyroid autonomy.  (+info)

RhoA activity is required for fibronectin assembly and counteracts beta1B integrin inhibitory effect in FRT epithelial cells. (6/4177)

FRT thyroid epithelial cells synthesize fibronectin and organize a network of fibronectin fibrils at the basal surface of the cells. Fibronectin fibril formation is enhanced by the overexpression of the ubiquitous beta1A integrin and is inhibited by the expression of the dominant-negative beta1B subunit. We tested the hypotheses that RhoA activity might mediate the integrin-dependent fibronectin fibrillogenesis and might counteract beta1B integrin inhibitory effect. FRT-beta1A cells were transfected with a vector carrying a dominant negative form of RhoA (RhoAN19) or treated with the C3 transferase exoenzyme. Both treatments inhibited fibronectin assembly and caused loss of actin microfilaments and adhesion plaques. On the other hand, FRT-beta1B cells were transfected with the constitutively activated form of RhoA (RhoAV14) or treated with the E. coli cytotoxic necrotizing factor 1, which directly activates RhoA. Either treatment restored microfilament and adhesion plaque assembly and promoted fibronectin fibril organization. A great increase in fibronectin fibril assembly was also obtained by treatment of FRT-beta1B cells with TGF-beta. Our data indicate that RhoA is required to promote fibronectin matrix assembly in FRT cells and that the activation of the signal transduction pathway downstream of RhoA can overcome the inhibitory effect of beta1B integrin.  (+info)

Thyroid volumes and urinary iodine in Swiss school children, 17 years after improved prophylaxis of iodine deficiency. (7/4177)

Salt iodine content in Switzerland was raised from 7.5 to 15 mg per kg in 1980, and since then dietary iodine intake has been considered to be sufficient, even though a slight decrease due to imported food has recently been reported. The aim of this study was to establish normal values for thyroid volumes of school children who can be assumed to have had a sufficient iodine intake all their lifetime. Moreover. the present investigation was undertaken to verify that iodine sufficiency had been achieved equally in two regions each served by one of the two Swiss salt producers. Mean iodine concentration in urine spot samples from school children was 16.1 microg/dl, and it was identical in both the city of Lausanne (n=215) and the city of Solothurn (n=208). Thus it can be stated that in both cities (served by two different salt producers) iodine intake is equal and sufficient. Accordingly, thyroid volumes measured by ultrasound in school children aged 6 to 16 years were the same in both Lausanne (n=202) and Solothurn (n=207). Moreover, the age-adjusted median volumes at the 97th percentiles closely agree with and validate provisional international reference values recently proposed by the World Health Organisation and by the International Council for Control of Iodine Deficiency Disease.  (+info)

Regulation of PiT-1, a sodium-dependent phosphate co-transporter in rat parathyroid glands. (8/4177)

A cDNA encoding an Na+-Pi co-transporter, termed rat PiT-1, has now been isolated from rat parathyroid. Expression of rat PiT-1 in Xenopus oocytes revealed that it possesses Na+-dependent Pi co-transport activity. The amount of PiT-1 mRNA in the parathyroid of vitamin D-deficient rats was reduced compared with that in normal animals, and increased markedly after administration of 1,25-dihydroxyvitamin D3. Furthermore, the abundance of PiT-1 mRNA in the parathyroid was much greater in rats fed a low-Pi diet than in those fed a high-Pi diet. Thus, rat PiT-1 may contribute to the effects of Pi and vitamin D on parathyroid function.  (+info)

Thyroid surgeries are common operations with an extremely low mortality. It is associated with specific morbidities which are dramatically decreased due to the rapid progression in operative techniques which helped to make the thyroid surgery less feared and better understood than it once was. Inferior thyroid artery is one of the vital structures that require special attention during operative technique in order to avoid troublesome and in most cases a preventable complications. We conducted this study to assess the: Prevalence and significance of post-operative hypoparathyroidism following thyroid surgery, with or without inferior thyroid artery ligation. Incidence of recurrent laryngeal nerve injury with or without inferior thyroid artery ligation. Intraoperative and post operative bleeding with or without inferior thyroid artery ligation. A prospective observational study was done from June 2005 to June 2008, at Basrah General Hospital. One hundred and eight patients underwent subtotal
Objective: The purpose of this study was to evaluate the levels of caveolin-1 in thyroid follicular epithelial cells of papillary thyroid cancer, follicular thyroid cancer, and nonmalignant thyroid nodule benign follicular adenoma, as well as to explore the relationship between the levels of caveolin-1 and thyroid function. The serum TSH level was associated with caveolin-1 manifestation in thyroid epithelial cells. Summary: Caveolin-1 may participate in regulating thyroid function and is a potential biomarker of follicular thyroid malignancy. for 10 minutes. The supernatant was added to the sample buffer (4:1), heated at 100C for 10 minutes, and then frozen at ?20C. Western Blot Samples comprising equal amounts of protein were separated by 12% sodium dodecyl sulfate polyacrylamide gradient gel electrophoresis, then electroblotted onto polyvinylidene difluoride membranes. The membranes were clogged with 5% skim milk at room temp for 2 hours and incubated with the primary antibody ...

Thyroid Arteries. The superior thyroid artery is typically the first branch of the external carotid artery. Most of its flow directed into the thyroid bed, with a characteristic thyroid blush on catheter angiography. It is very often seen on a (well-performed) CTA. A superior laryngeal branch often arises from the superior thyroid artery.. The superior thyroid artery (latin: arteria thyreoidea superior) is a branch of the external carotid artery that arises from the anterior surface of the external carotid.The superior thyroid artery supplies the thyroid gland, infrahyoid neck muscles, tissues of the upper part of the larynx, as well as the sternocleidomastoid and cricothyroid muscles.. The superior thyroid artery is located within the neck. Branching off from the external carotid artery, this blood vessel runs past the greater cornu of the hyoid bone (the hyoids back-most ….

Objectives: Celiac disease (CD) is associated with thyroid autoimmunity and other autoimmune diseases. Data are, however, lacking regarding the relationship between thyroid autoimmunity and thyroid function, especially in regard to CD. Our aim was to investigate the impact of thyroid autoimmunity on thyroid function in 12-year-old children with CD compared to their healthy peers. Methods: A case-referent study was conducted as part of a CD screening of 12-year-olds. Our study included 335 children with CD and 1695 randomly selected referents. Thyroid autoimmunity was assessed with antibodies against thyroid peroxidase (TPOAb). Thyroid function was assessed with thyroid-stimulating hormone and free thyroxine. Results: TPOAb positivity significantly increased the risk of developing hypothyroidism in all children. The odds ratios (with 95% confidence intervals) were 5.3 (2.7-11) in healthy 12-year-olds, 10 (3.2-32) in screening-detected CD cases, 19 (2.6-135) in previously diagnosed CD cases, and ...

An ultrasound uses sound waves to develop images, and it is the most sensitive imaging modality available for examining the thyroid gland. A thyroid ultrasound also has the benefit of being non-invasive, it doesnt use ionizing radiation, and it is less expensive than other imaging techniques such as an MRI and CT scan. But does this mean that everyone with a suspected or confirmed thyroid or autoimmune thyroid condition should consider getting a thyroid ultrasound? Ill of course answer this and other questions you may have in this blog post.. When I was diagnosed with Graves Disease, the endocrinologist I saw didnt want to do a thyroid ultrasound. After palpating my thyroid gland she didnt detect any thyroid nodules, and while I appreciated her trying not to recommend any unnecessary tests, I talked her into doing a thyroid ultrasound. Other than some thyroid swelling it came back clean, as I had no thyroid nodules.. Since I requested a thyroid ultrasound even though my endocrinologist ...
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 ...
Thyroid Glands - Tissue and Systems. This article describes the basic anatomy and function of the thyroid gland. An understanding of the basic form and physiology of the thyroid gland will allow better recognition of a possible thyroid cancer. Thyroid cancer is rare and account for less than 1% of all cancers in the United States. It is still important to consider because the majority of thyroid cancers are quite treatable and even curable if detected early enough. This emphasizes the importance of recognizing symptoms that should prompt investigation with possible diagnosis. Early diagnosis and treatment, as with the vast majority of cancers, will provide the best possible outcomes.. The thyroid gland is a small endocrine organ that sits in the front of the neck. The name thyroid comes from a Greek word meaning shield. The thyroid gland looks a bit like an ancient shield or perhaps like a butterfly with two wings and two tips on each wing. The thyroid gland uses iodine and proteins from the ...

Female head and tyroid gland. Coloured computer-enhanced gamma scan (scintigram) of a healthy human thyroid gland. The thyroid gland is a main endocrine gland situated at the base of the neck, and is divided into two lobes (as seen). The radioactive tracer Technetium-99m used in this gamma scan shows areas of activity (yellow) within the gland. The thyroid produces and stores hormones which control the basal metabolic rate of the body, influence growth and maturation, and regulate blood calcium levels. Gamma scanning involves introducing a radioactive tracer into the body, which is taken up by certain organs and detected as gamma rays by a gamma camera. - Stock Image C023/8567
TY - JOUR. T1 - Synergistic repression of thyroid hyperplasia by cyclin C and Pten. AU - Jezek, Jan. AU - Wang, Kun. AU - Yan, Ruilan. AU - Di Cristofano, Antonio. AU - Cooper, Katrina F.. AU - Strich, Randy. PY - 2019/8/15. Y1 - 2019/8/15. N2 - The cyclin C-Cdk8 kinase has been identified as both a tumor suppressor and an oncogene depending on the cell type. The genomic locus encoding cyclin C (Ccnc) is often deleted in aggressive anaplastic thyroid tumors. To test for a potential tumor suppressor role for cyclin C, Ccnc alone, or Ccnc in combination with a previously described thyroid tumor suppressor Pten, was deleted late in thyroid development. Although mice harboring individual Pten or Ccnc deletions exhibited modest thyroid hyperplasia, the double mutant demonstrated dramatic thyroid expansion resulting in animal death by 22 weeks. Further analysis revealed that Ccncthyr-/- tissues exhibited a reduction in signal transducer and activator of transcription 3 (Stat3) phosphorylation at ...
It distributes twigs to the adjacent muscles, and numerous branches to the thyroid gland, connecting with its fellow of the opposite side, and with the inferior thyroid arteries. The branches to the gland are generally two in number. One, the larger, supplies principally the anterior surface; on the isthmus of the gland it connects with the corresponding artery of the opposite side. A second branch descends on the posterior surface of the gland and anastomoses with the inferior thyroid artery.. Besides the arteries distributed to the muscles and to the thyroid gland, the branches of the superior thyroid are:. ...
Scintiscan of the Thyroid Gland. tuha_23_n.jpg: Female teenager with a node of the left lower pole of the thyroid gland which is distinctly palpable. In the Tc 99m- or 123 I-scan a minimal to missing accumulation of the tracer is recognizable in the same place. The diagnosis is an inactive node of the left lower thyroid gland pole. The significance of thyroid scan in childhood concerns the proof of thyroid gland tissue in case of suspected goitre at the tongue base, anywhere else and/or at the normal site; in addition, the recognition of hormonal activity and dignity of thyroid gland nodes in teenagers. As in adults, the work-up examinations of pathologies of the goitre in children include hormonal examinations, ultrasound, and in case of suspected malignancy, fine-needle aspiration. In case of a node of the thyroid gland, a scan is performed with the aim to know if there is no activity at all, normal activity, or hyperactivity in the node; mainly, if the TSH is less than 0.6 mU/L, a scan is ...
Background: Juvenile hypothyroidism is a very common problem in developing parts of world, and produces various skeletal manifestations. One of them is short stature and it is the most common reason for referral to endocrinologist.

The most important effects were represented by the dramatic junB and fra-1 gene induction, which was abolished by the block of the transformation-induced HMGI-C protein synthesis. Here, we have further characterized the transformation-dependent AP-1 activity, by analysing the expression of different jun- and fos-related components, in rat thyroid cell lines ...
HLA Class II molecules are expressed by human thyroid epithelial cells (thyrocytes) in thyroid autoimmunity, although these cells are normally Class II-. gamma-Interferon (gamma-IFN) is probably involved in this expression, as suggested by its ability to induce Class II in cultured normal thyrocytes. We have now found that thyroid stimulating hormone (TSH) enhances Class II expression induced in cultured thyrocytes by gamma-IFN, and effects similar to those of TSH were obtained with dibutyryl cyclic AMP. A proportion of thyrocytes also expressed Class II following treatment with TSH or dibutyryl cyclic AMP in the absence of gamma-IFN, but the optimal activity of these mediators then appeared to be dependent upon the occurrence of some pre-existing Class II expression. These findings give insights into how a variety of mediators may influence Class II expression in thyroid autoimmunity.
NKX2-1 plays a critical role in thyroid differentiation. Recently, we established Side Population cells-derived Thyroid cell line (SPTL) from mouse thyroid Side Population cells. In SPTL cells, NKX2-1, PAX8 and E-cadherin were not expressed when examined by western blotting. Immunocytochemistry revealed that only 1% of SPTL cells were NKX2-1 positive. When GFP-SPTL cells were directly injected into mouse thyroid, a few GFP-SPTL cells with weak expression of NKX2-1 were found in part of thyroid follicle, suggesting that SPTL cells have potential of thyroid stem cells. Comprehensive gene expression analysis indicated that TGF-beta signaling pathway is critical for SPTL cells. TGF-beta signaling and NKX2-1 appear to play an important role in thyroid stem cells and thyroid differentiation. Here we show that NKX2-1 regulates both SMAD and non-SMAD pathways in SPTL cells. To examine the role of NKX2-1 in SPTL cells, we produced SPTL cells having doxycycline-inducible Nkx2-1 expression (named ...
IntroductionDuring pregnancy, physiologic changes in maternal thyroid function take place especially due to hormonal as well as metabolic processes. Human chorionic gonadotropin activates the maternal thyroid gland leading to increased thyroid hormone production. A sufficient availability of maternal thyroid hormones is essential for fetal development, especially during the first trimester of pregnancy, when the fetal thyroid gland is not yet functional.Materials and MethodsCurrent knowledge of thyroid dysfunction including thyroid autoimmunity, hypothyroidism or hyperthyroidism is summarized with special focus on miscarriage and pregnancy disorders. Therefore, a Medline research as well as an analysis of current guidelines on thyroid function and pregnancy was performed.ResultsA study focusing on TSH levels in normal and disturbed pregnancies, the risk of miscarriage in association with thyroid autoantibodies, and (subclinical) hypothyroidism in infertile and fertile women were included
A thyroid function test measures the efficiency of thyroxine and triiodothyronine production by the thyroid gland. These two thyroid hormones which contain iodine, regulate body metabolism. If the hormones are deficient, as in the condition called myxedema, metabolism is slowed down. If they are in excess, as in exophthalmic Goiter, metabolism is accelerated. The oldest method of measuring thyroid function is the determination of the basal metabolic rate, or BMR. The relationship of the BMR to thyroid hormone levels, however, is indirect and inexact. The BMR test has thus been superseded by such test as the radiation method, which measures the rate at which injected radioactive iodine become concentrated in the thyroid gland. This rate is directly related to the rate of thyroid hormone synthesis. Other test include measurement of the competitive protein binding of thyroxine, serum thyroxine, the level of thyroid stimulating hormone (TSH), free thyroxine in blood and urine, and triiodothyronine ...
Hashimotos thyroiditis is also known as struma lymphomatosa, lymphocytic thyroiditis, or chronic autoimmune thyroiditis. It is characterized by autoimmune destruction of the thyroid gland and is the most common cause of hypothyroidism in iodine-sufficient regions. It is more common in females than males. It is classically seen in the fifth decade; however, a juvenile form exists that presents at a mean age of 11 years.[1]. In symptomatic patients, the initial presentation may be that of hyperthyroidism as a result of the destruction of follicles. The destruction of the thyroid gland progresses to hypothyroidism, with decreased T4 and increased thyroid-stimulating hormone. Diffuse enlargement of the thyroid may occur at presentation, though less commonly it can present as one or more nodules. Autoantibodies such as antithyroglobulin and antithyroid peroxidase may also be present and relate to thyroid damage. Most patients have detectable serum concentrations of antibodies against at least one ...
Evidence has accumulated indicating that thyroid function may be considerably influenced by the endocrine pancreas. It is known that thyroid release is stimulated: by insulin administration but relatively little work has been done investigating the effects of diabetes on thyroid release. The present investigation studies thyroid release in normal, semi-starve, and diabetic mice. Diabetes was induced by a single streptozotocin injection (200 mg/kg body weight). The animals were maintained on a low iodine diet (LID) and on a regular iodine diet (RID). Using an in vitro technique, cultured thyroid glands of the diabetic animals were found to have no significant difference in thyroid release on either of the diets employed ...

Thyroid Gland is located in the neck. Thyroid follicles secret thryoglobulin, a storage form of thyroid hormone. Thyroid stimulating hormone (TSH) from anterior pituitary causes conversion of thyroglobulin into thyroid hormones T4 and T3. Almost all body cells are targets of thyroid hormones. Thyroid hormones increase overall metabolic rate, regulate growth and development, and influence onset of sexual maturity. Calcitonin regulates calcium. Thyroid hormones regulate metabolism, thereby affecting body temperature and weight. Thryoid hormones contian iodine, and an iodine deficiency causes the bodys feedback loops to request more thyroid hormones. The thyroid gland enlarges to compensate, causing a condition called goiter.. ...
Recommendation: The clinical presentation is consistent with a cold thyroid gland nodule. The possibility of malignancy is not excluded based on normal thyroid gland function. The workup of such thyroid gland nodules evolved over the past decade. Currently, an ultrasound-guided fine needle biopsy is recommended. The results of the cytology can guide the treatment: observation is recommended for a macrofollicular pattern or clear benign colloid pattern, while surgery is recommended for microfollicular pattern or clear evidence of carcinoma.. The extent of surgery is dictated by the histology as well: a hemithyroidectomy is reasonable if the needle biopsy was not diagnostic of carcinoma but showed a microfollicular pattern. In such a case, it is recommended to perform frozen section histopathology examination of the surgical specimen and proceed to total or subtotal thyroidectomy if cancer was found on the frozen section diagnosis. On the other hand, a total or subtotal thyroidectomy is ...
The TSH stimulation test is used to identify thyroid tissue which is being suppressed by an autonomously functioning thyroid nodule (high levels of circulating thyroid hormone may suppress TSH release and thus, normal glandular function) or functioning thyroid metastasis. Exogenous bovine TSH is administered once daily for 1 to 3 days. Suppressed normal thyroid tissue should be visualized following TSH stimulation. Patients with thyroid atrophy or diseased or damaged thyroid tissue will not have significant change in the appearance of their scans. Although this test was used frequently in the past to distinguish primary from secondary hypothyroidism, it no longer is necessary now that serum TSH levels are now available. In addition, the use of bovine protein may be associated with the risk of a major allergic reaction. More recently, the administration of recombinant human TSH (rhTSH) has been proposed as an effective agent for detecting residual or metastatic thyroid tissue in patient with ...
1. Human thyroid tissue may be kept alive and in good condition in the Lindbergh apparatus for at least 3 weeks, in usable condition from 1 to 2 months, provided that the vascular tree remain patent and functioning.. 2. Experiments with altered amounts of iodin, adrenalin, hormones, and other substances show constant results only in connection with eschatin and pitressin which, in concentrations of 1:1000 in the perfusate almost invariably cause hyperplasia of the explanted tissue.. 3. The original state of the tissue and the character of the symptom complex in the patient from which it was taken appeared to play no part in the subsequent behavior of the tissue explants.. 4. In one experiment a most remarkable metaplasia was observed in the explanted thyroid tissue during the 6 to 8 weeks that it remained in two apparatuses. The cause of this is not evident.. ...
The thyroid gland is a bilobed gland located in the anterior neck in front of the trachea (windpipe), and larynx (voice box). The thyroid is divided into right and left lobes, isthmus, and pyramidal lobe. The gland is very vascular. The thyroid gland has two major classes of cells. The follicular cells produce thyroid hormones, and the parafollicular cells produce Calcitonin. Thyroxin (T4) and triiodothyronine (T3) are the two major hormones produced by the thyroid follicular cells. These hormones are excreted into the bloodstream and play critical roles in regulating body metabolism. Excess thyroid hormone production results in hyperthyroidism and decreased or absent thyroid hormone production results in hypothyroidism. Calcitonin, produced by the parafollicular cells plays a role in calcium metabolism.. The gland is often difficult to feel in its normal state, but enlargement of the gland (goiter) or a thyroid mass may be palpable in the neck as a mass that elevates with swallowing. The ...
Decreased thyroid gland function, hypothyroidism is a disease caused by a lack of thyroid hormones. This disease has a range of specific symptoms.
The thyroid is a butterfly-shaped gland that lies in front of the windpipe, also known as the trachea, and just below the voice box, also called the larynx. This gland makes hormones that regulate the way the body uses energy.. The thyroid gland uses iodine from food to make two thyroid hormones: thyroxine (T4) and triiodothyronine (T3). The thyroid gland stores these hormones and releases them into the bloodstream as they are needed.. If the thyroid gland does not produce enough hormones, it is called hypothyroidism. If the gland produces too many hormones, it is called hyperthyroidism. Problems with the thyroid gland can affect many body systems. Changes in weight, heartbeat, body temperature, digestion, and muscle function are common. Both hypothyroidism and hyperthyroidism can be treated, usually with medicine and sometimes with surgery. ...
The inferior thyroid artery supplies blood to the thyroid and parathyroid glands, plus muscles and structures that help you breathe, eat, and speak.
What is the function of the Thyroid gland?. The thyroid gland produces hormones that can cause hair changes, sleep disruptions, weight fluctuations, mood changes and much more. On the other hand, the gland itself can grow and push on its surroundings, form lumps, and even turn into cancer. It some cases it can even cause voice and swallowing problems.. How is the Thyroid gland function and size assessed?. The thyroid hormone level can be tested via blood work. The size of the thyroid gland or lumpiness may or may not be a cause for hormone disturbance. The shape, size, and presence of lumps inside of the thyroid gland is best assessed by the Ultrasound. The Ultrasound is performed by hand (unlike CAT scan and MRI that is performed by a computer), it is always better for the surgeon to personally evaluate the thyroid gland and have a mental picture of what is happening to the gland.. Most of the thyroid hormone abnormalities can be managed by medications. Low levels of the hormone are treated by ...
Thyroid surgery is an operation to remove part or all of the thyroid gland. It is performed in the hospital, and general anesthesia is usually required. Usually the operation removes the lobe of the thyroid gland containing the lump and possibly the isthmus. A frozen section (an immediate pathological reading) may or may not be used to determine if the rest of the thyroid gland should be removed. Sometimes, based on the result of the frozen section, the surgeon may decide to stop and remove no more thyroid tissue, or proceed to remove the entire thyroid gland, and/or other tissue in the neck. This is a decision usually made in the operating room by the surgeon based on findings at the time of surgery. These options will be discussed by your surgeon with you preoperatively.. After surgery you may have a drain (a tiny piece of plastic tubing), which prevents fluid from building up in the wound. This is removed after the fluid accumulation is minimal. Most patients are discharged two to three ...
Without a functioning thyroid, you dont need to be particularly concerned about soy or other goitrogenic foods (i.e., brussel sprouts, broccoli, etc.) and their ability to interfere with your thyroid function .. Those without a functioning thyroid are totally dependent on thyroid hormone replacement for all their thyroid hormone. You may find that you have less fluctuation in thyroid function and find it easier to stabilize your dose and maintain an optimal TSH level on a consistent dose, as compared to patients with autoimmune thyroid disease who still have a gland. (This is because when the gland is still present and capable of functioning, it may occasionally sputter to life and produce thyroid hormone, making regulation of thyroid levels more difficult.) Thyroid cancer patients who have had the thyroid gland removed are in a unique situation in that they are given thyroid hormone replacement drugs at suppressive levels. This means that the objective is to give sufficient level of ...

The nuclear features which characterise the thyroid gland papillary carcinoma are absent. It is linked to radiation and comprises approximately 10% to 15% of thyroid cancers. Clinically, it usually presents as a solitary mass in the thyroid gland. It is generally unifocal and thickly encapsulated and shows invasion of the capsule or the vessels. Diagnostic procedures include: thyroid function tests, thyroid radioisotope scanning, thyroid ultrasound and fine needle biopsy. Treatment options include: partial or complete thyroidectomy. Adjuvant treatment options include: radioiodine therapy, TSH suppression and external ...
Follicular cells take up iodide and amino acids from the blood circulation on the basolateral side, synthesize thyroglobulin and thyroperoxidase from amino acids and secrete these into the thyroid follicles together with iodide. The follicular cells subsequently take up iodinated thyroglobulin from the follicles by endocytosis, extract thyroid hormones from it with the help of proteases and subsequently release thyroid hormones into the blood. These thyroid hormones are transported throughout the body where they control metabolism (which is the conversion of oxygen and carbohydrates to energy). Every cell in the body depends upon thyroid hormones for regulation of their metabolism. The normal thyroid gland produces about 80% T4 and about 20% T3, however, T3 is about four times as potent as T4. ...
In humans, the thyroid gland is an unpaired organ in the form of a dark red or brownish-red tubercle, located on the neck in front of the upper part of the respiratory throat under the larynx. The gland consists of two lobes (right and left), interconnected by an isthmus. Sometimes the isthmus is absent, and then both lobes are in contact or separated by a gap. For many people, another lobe, which is called pyramidal, moves up from this isthmus in the form of a long outgrowth. The thyroid gland is very rich in blood vessels. Blood is delivered by four arteries, and carried away by the corresponding veins. The gland is abundantly supplied with lymphatic vessels flowing into the deep cervical lymph nodes. The thyroid gland receives innervation from the cervical sympathetic, as well as from the superior laryngeal nerve (nervus laringeus superior). Often in humans and mammals, there are additional thyroid glands in the form of small round, oval or irregularly shaped bodies that are found throughout ...
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 ...
An increased thyroid gland function, hyperthyroidism is a disease characterized by weight loss, increased sweating, tiredness and restlessness. If left untreated, it can endanger the patients life.
One of the most important factors that leads to hypothyroidism is exposure to environmental toxins such as pesticides, which act as hormone or endocrine disruptors and interfere with thyroid hormone metabolism and function.. In fact, one study found that as people lost weight they released pesticides from their fat tissue.. This then interfered with their thyroid function and caused hypothyroidism. The toxins created a slow metabolism and prevented them from losing more weight.. This study highlights the importance of overall detoxification. It is quite a significant finding that shows exactly how toxins interfere with thyroid function.. Heavy metals such as mercury can also affect thyroid function. I see many people with chronic hypothyroidism and other thyroid problems because mercury interferes with normal thyroid function.. The other big factor that interferes with thyroid function is chronic stress.. There is an intimate interaction between stress hormones and thyroid function. The more ...

133 with papillary thyroid carcinoma after total thyroidectomy.. In the patients with mildly suppressed TSH (0.03 , TSH ≤0.3 μIU/mL) and fT3 levels equivalent to their preoperative levels, all metabolic markers remained equivalent to their preoperative levels. The serum biochemical markers of thyroid function in patients on LT4 following total thyroidectomy suggest that the patients with mildly suppressed TSH levels were closest to euthyroid. Whereas those with normal TSH levels were mildly hypothyroid and those with strongly suppressed TSH levels were mildly hyperthyroid. These data may provide novel information on the management of patients following total thyroidectomy for thyroid cancer or benign thyroid disease.. Comment: T4 therapy with TSH between 0.03-0.3 was associated with normal biochemical markers, whereas TSH lower was associated with hyperthyroid markers, and above 0.3 was associated with hypothyroid makers.. ...

If the thyroid gland is producing too much thyroid gland (a condition known as hyperthyroidism), the thyroid gland produces less TSH to reduce the thyroid production of thyroid hormones. After the thyroid gland is not producing enough thyroid gland (a condition known as endometriosis ), the adrenal gland produces more TSH to stimulate the thyroid gland and boost its production.

The earliest oral treatment for hypothyroidism consisted of thyroid extract. George Redmayne Murray of the United Kingdom first described treatment of myxedema with thyroid extract in 1891, and published a description of long-term successful treatment (28 years) of a patient with myxedema (severe hypothyroidism) in 1920[17] His treatment was quickly adopted in North America and Europe. The first recorded American use dates to 1891 by a woman who was still taking it 52 years later at 84 years of age [18] Desiccated thyroid extract is prepared from pig thyroid glands. The glands are dried (desiccated), ground to powder, combined with binder chemicals, and pressed into pills. This was a new use for parts that were previously unwanted slaughterhouse offal, and Armour and Company, the dominant American meatpacker in the 20th century, supplied the best-known brand of thyroid extract.[citation needed] Replacement by thyroid extract in hypothyroidism was one of the most effective treatments of any ...

Hypopthyroidism can therefore be defined as primary when it is the thyroid gland that is diseased and not producing sufficient thyroid hormones. It can alternatively be defined as secondary when the thyroid gland is healthy and able to produce sufficient thyroid hormones but is not stimulated appropriately or has insufficient constituents to produce thyroid hormone. In these cases the problem does not lie in the thyroid gland but in outside factors that influence the gland. Hypothyroidism tends to cause very obvious symptoms and is therefore easily detectable. It is also easily treated and managed with regular intake of synthetic thyroid hormones.. ...
The transcription factor Pax8 is expressed during thyroid development and is involved in the morphogenesis of the thyroid gland and maintenance of the differentiated phenotype. To date, Pax8 has been shown to regulate all the genes that are considered markers of thyroid differentiation. To identify novel Pax8 target genes we performed a genome-wide expression analysis following Pax8 siRNA. The silencing of Pax8 expression in rat thyroid differentiated FRTL-5 cells and the subsequent analysis of the gene expression profile by microarray identified Wnt4 among the down-regulated genes. As the other members of the Wnt family, Wnt4 has been implicated in several developmental processes including regulation of cell fate and patterning during embryogenesis. Up to now, the only data on Wnt4 in thyroid concern its down-regulation as necessary for the progression of thyroid epithelial tumors. Currently, we believe that it could be involved in thyroid morphogenesis, development and in the maintenance of ...
Chapter 6 - The Hypothalamic-Pituitary-Thyroid Axis: Anatomy and Physiology.

The BDNF protein is encoded by a gene that is also called BDNF, found in humans on chromosome 11.[7][8] Structurally, BDNF transcription is controlled by 8 different promoters, each leading to different transcripts containing one of 8 untranslated 5' exons (I to VIII) spliced to the 3' encoding exon. Promoter IV activity, leading to the translation of exon IV-containing mRNA, is strongly stimulated by calcium and is primarily under the control of a Cre regulatory component, suggesting a putative role for the transcription factor CREB and the source of BDNF's activity-dependent effects .[32] There are multiple mechanisms through neuronal activity can increase BDNF exon IV specific expression.[32] Stimulus-mediated neuronal excitation can lead to NMDA receptor activation, triggering a calcium influx.

In humans, the IGF2 gene is located on chromosome 11p15.5, a region which contains numerous imprinted genes. In mice this homologous region is found at distal chromosome 7. In both organisms, Igf2 is imprinted, with expression resulting favourably from the paternally inherited allele. However, in some human brain regions a loss of imprinting occurs resulting in both IGF2 and H19 being transcribed from both parental alleles.[6] The protein CTCF is involved in repressing expression of the gene, by binding to the H19 imprinting control region (ICR) along with Differentially-methylated Region-1 (DMR1) and Matrix Attachment Region −3 (MAR3). These three DNA sequences bind to CTCF in a way that limits downstream enhancer access to the Igf2 region. The mechanism in which CTCF binds to these regions is currently unknown, but could include either a direct DNA-CTCF interaction or it could possibly be mediated by other proteins. In mammals (mice, humans, pigs), only the allele for insulin-like growth ...
