Expression of type II iodothyronine deiodinase in brain tumors.
Type II iodothyronine deiodinase (DII) messenger ribonucleic acid (mRNA) and its activity have been demonstrated in human normal brain. Although DII activity has been demonstrated in brain tumors, expression of DII mRNA has not been studied in these tumors. To investigate the mechanisms involved in the expression of DII activity in brain tumors, we studied DII mRNA and DII activity in astrocyto...
متن کاملMolecular cloning, expression and radiation hybrid mapping of the bovine deiodinase type II (DIO2) and deiodinase type III (DIO3) genes.
Thyroid hormones play a critical role in mammalian development and metabolism. Their activity is regulated in a complex, tissue-specific manner by three isoforms of deiodinases. The goal of this study was to sequence the full-length bovine type II deiodinase (DIO2) and type III deiodinase (DIO3) cDNAs and characterize mRNA expression levels of each of the three deiodinase isoforms in several bo...
متن کاملSpecies differences in liver type I iodothyronine deiodinase.
The type I iodothyronine deiodinase (ID-I) of liver is an important enzyme for the conversion of the prohormone thyroxine (T4) to the active thyroid hormone 3,3',5-triiodothyronine (T3). Because it is an integral membrane protein of low abundance, purification of ID-I from rat liver has proven to be difficult. We have analyzed ID-I in liver microsomal fractions from various animals to reveal po...
متن کاملRegulation of type 1 iodothyronine deiodinase by LXRα
The iodothyronine deiodinases are selenoenzymes that regulate the activity of thyroid hormone via specific inner- or outer-ring deiodination. In humans, type 1 deiodinase (D1) is highly expressed in the liver, but the mechanism by which its gene expression is regulated remains to be elucidated. Liver X receptor α (LXRα), a transcription factor of the nuclear receptor superfamily, is highly expr...
متن کاملThe actin cytoskeleton mediates the hormonally regulated translocation of type II iodothyronine 5'-deiodinase in astrocytes.
Thyroid hormone, specifically thyroxine, alters cytoskeletal organization in astrocytes by modulating actin polymerization and, in turn, regulates the turnover of the short-lived membrane protein, type II iodothyronine 5'-deiodinase. In the absence of thyroxine, approximately 35% of the total cellular actin is depolymerized, and greater than 90% of the deiodinase is found in the plasma membrane...
