Thyroglobulin gene mutation is a rare cause of congenital hypothyroidism, but thyroglobulin gene mutations are thought to be associated with thyroid cancer development. A 21-year-old Japanese man treated with levothyroxine for congenital hypothyroidism had an enlarged thyroid gland with undetectable serum thyroglobulin despite elevated serum TSH level. The patient was diagnosed with thyroglobul...

Six hundred and twelve monoclonal Ig (MIg) were studied for their antibody activity against the following autoantigens: actin, tubulin, thyroglobulin, myosin, myoglobin, fetuin, albumin, transferrin, and double-stranded DNA (dsDNA). Of these 612 MIg, 36 (i.e., 5.75%) were shown to possess antibody activity. Thirty-two of these 36 (5.22% of the total) were mainly directed against actin. The four...

conclusions thyroid dysfunction was not higher in sle patients compared to healthy individuals. however, anti-tg antibodies were higher in sle patients. it has not yet been established that thyroid function tests should be performed routinely in sle patients. results the mean age of sle patients and controls were 32.16 ± 9.19 and 32.48 ± 9.47 years, respectively (p = 0.821). patients had signif...

INTRODUCTION Clinical manifestations of Immunoglobulin A Deficiency (IgAD) include recurrent infections, atopy and autoimmune diseases. However, to our knowledge, the concomitant evaluations of autoimmune diseases and autoantibodies in a cohort of IgAD patients with current age > 10 years-old and their relatives have not been assessed. OBJECTIVES To evaluate autoimmune diseases and the presen...

32 patients (19 female. 13 male)• suffering from Graves' disease with exophthalmus and five without exophthalmus were studied for various autoantibodies including anti-thyroglobulin (ATAB). anti-microsomal antibody (AMAB). anti-parietal antibodies (APAB) and also circulating immune complex (CrC). 43 normal subjects were tested concurrently. Immunofluorescent technique was employed for auto...

Bovine thyroglobulin was treated with increasing ratios of succinic anhydride, trinitrobenzene sulfonic acid, tetranitromethane, and N-acetylimidazole in an attempt to assess the role of lysine or tyrosine residues in binding to thyroid membrane receptors. Extensive succinylation results in dissociation to 12 S thyroglobulin with retention of a considerable portion of the three-dimensional stru...

Serum thyroglobulin measurement by immunoassay is used to detect residual or recurrent thyroid cancer after thyroid ablation. However, the usefulness of immunoassay is limited by both the requirement for thyroid hormone withdrawal to attain optimal test sensitivity and interference by antithyroglobulin antibodies. To circumvent these problems, we amplified thyroglobulin messenger ribonucleic ac...

The kinetics of iodination and oxidation of hog thyroglobulin were studied with purified hog thyroid peroxidase and the results were compared with the reactions of free tyrosine. From Lineweaver-Burk plots and on the basis of a value of 0.83 for delta epsilon mM at 289 nm/iodine atom incorporated, the rate constant for transfer of an assumed enzyme-bound iodinium cation to thyroglobulin was est...

Bovine thyroglobulin has been subjected to sequential glycohydrolase treatment in order to define further the components of the carbohydrate chain which are important in binding of the glycoprotein to bovine thyroid membranes. Preparations of asialoagalactothyroglobulin exhibit the best binding, suggesting that exposed N-acetylglucosamine residues on the B carbohydrate chain of thyroglobulin pl...

Abstract Background Obesity-related oxidation stress plays a key role in obesity complications; however, its relation to thyroid status is an area for further research. The study aimed assess function obese children and oxidative deoxyribonucleic acid (DNA) damage. Results Fifty 40 normal weight were included . Anthropometric measurement, lipid profile, function, anti-thyroglobulin antibody, pe...
