Mice with targeted disruption of the Dio2 gene have cold-induced overexpression …

- diabetesjournals.org
MA Christoffolete, CCG Linardi, L de Jesus, KN Ebina, … - Diabetes, 2004 - Am Diabetes Assoc
The Dio2 gene encodes the type 2 deiodinase (D2) that activates thyroxine (T4) to 3,3′,5-triiodothyronine
(T3), the disruption of which (Dio2 −/− ) results in brown adipose tissue (BAT)-specific hypothyroidism
in an otherwise euthyroid animal. In the present studies, cold exposure increased Dio2 ...

The type 2 iodothyronine deiodinase is essential for adaptive thermogenesis in …

LA de Jesus, SD Carvalho, MO Ribeiro, M … - Journal of Clinical …, 2001 - Am Soc Clin Investig
Type 2 iodothyronine deiodinase (D2) is a selenoenzyme, the product of the recently cloned
cAMP-dependent Dio2 gene, which increases 10- to 50-fold during cold stress only in brown
adipose tissue (BAT). Here we report that despite a normal plasma 3,5,3′- ...

Hearing loss and retarded cochlear development in mice lacking type 2 …


L Ng, RJ Goodyear, CA Woods, MJ … - Proceedings of the …, 2004 - National Acad Sciences
The later stages of cochlear differentiation and the developmental onset of hearing require thyroid
hormone. Although thyroid hormone receptors (TRs) are a prerequisite for this process, it is likely
that other factors modify TR activity during cochlear development. The mouse cochlea ...

Insights into the role of deiodinases from studies of genetically modified animals


DLS Germain, A Hernandez, MJ Schneider, VA Galton - Thyroid, 2005 - liebertonline.com
The deiodinases function at a prereceptor level in tissues to modulate the concentrations, and
thus the actions, of thyroid hormones. Although much has been learned in the last two decades
about the biochemical proper- ties and expression patterns of these enzymes, a complete ...

Thermogenesis and energy expenditure: control of heat production by the Ca 2+- …


M Reis, M Farage, L Meis - Molecular membrane biology, 2002 - informahealthcare.com
Summary This report measured the amount of heat released during Ca2+ transport and ATP
hydrolysis by vesicles derived from the sarcoplasmic reticulum of rabbit slow (SM) and fast
(FM) muscle. During ATP hydrolysis, part of the chemical energy released is used to ...

Atypical expression of type 2 iodothyronine deiodinase in thyrotrophs explains the …

- endojournals.org
MA Christoffolete, R Ribeiro, P Singru, C Fekete, WS … - Endocrinology, 2006 - Endocrine Soc
T 4 , the main product of thyroid secretion, is a critical signal in plasma that mediates the
TSH-negative feedback mechanism. As a prohormone, T 4 must be converted to T 3 to acquire
biological activity; thus, type 2 iodothyronine deiodinase (D2) is expected to play a critical ...

The role of deiodinases in amphibian metamorphosis


DD Brown - Thyroid, 2005 - liebertonline.com
Valerie Galton's prediction over 40 years ago that deiodinases would be important in amphibian
metamor- phosis has been confirmed. Expression of iodothyronine deiodinase type 2 (D2) and
type 3 (D3) occurs in em- bryogenesis at relevant locations long before the thyroid gland ...

Conserved cysteines in the type 1 deiodinase selenoprotein are not essential for …


W Croteau, JE Bodwell, JM Richardson, DLS … - Journal of Biological …, 1998 - ASBMB
The iodothyronine deiodinases are a family of oxidoreductases that catalyze the removal of iodide
from thyroid hormones. Each of the three isoforms contain selenocysteine at its active site and
several cysteine residues that may be important for catalytic activity. Of particular interest ...

Association between a novel variant of the human type 2 deiodinase gene …


D Mentuccia, L Proietti-Pannunzi, K Tanner, V Bacci, TI … - Diabetes, 2002 - ncbi.nlm.nih.gov
Thyroid hormone action is an important determinant of energy and glucose metabolism. T4 metabolism
is regulated by the deiodinases of which type 2 is expressed in humans in skeletal muscle and
brown adipose tissue, where its transcription is stimulated by the beta-3 adrenergic ...
