A new class of glutathione S-transferase enzymes named omega (GSTO) has been recently identified and shown to be expressed in a wide range of human tissues. A genetic polymorphism of the GSTO1 gene causing an alanine-to-aspartate (A140D) substitution in amino acid 140 produces a variant with lowered
Screening tools are of utmost necessity in order to identify individuals at risk for thyroid nodule cancer. The polymorphic inheritance of human drug-metabolizing enzymes, such as those encoded by the Glutathione-S-Transferase (GST) system, plays an important role in the development of most human
Nodular or multinodular goiter is the most common non-neoplastic thyroid disease and may be difficult to distinguish from true neoplastic thyroid diseases using microscopic criteria. We have used two-dimensional gel electrophoresis to study the protein patterns of thyroid tissues including normal
METHODS
Selenium (Se) is required for the biosynthesis of selenocysteine-containing proteins. Several selenoenzymes, e.g. glutathione peroxidases and thioredoxin reductases, are expressed in the thyroid. Selenoenzymes of the deiodinase family regulate the levels of thyroid hormones. For clinical
UNASSIGNED
As the most prevalent endocrine system malignancy, papillary thyroid carcinoma had a very fast rising incidence in recent years for unknown reasons besides the fact that the current methods in thyroid cancer diagnosis still hold some limitations. Therefore, the aim of this study was to
Because thyroid nodules are frequent in areas with iodine deficiency the aim of this study was to characterise molecular events during iodine deficiency that could explain mutagenesis and nodule formation. We therefore studied gene expression of catalytic enzymes prominent for H(2)O(2)
