Iodothyronines such as triiodothyronine (T(3)) and 3,5-diiodothyronine (T(2)) influence energy expenditure and lipid metabolism. Skeletal muscle contributes significantly to energy homeostasis, and the above iodothyronines are known to act on this tissue. However, little is known about the cellular/molecular events underlying the effects of T(3) and T(2) on skeletal muscle lipid handling. Since...
It is over 40 years since the original demonstration that thyroxine (T4), the principal secretory product of the thyroid, is deiodinated, to 3,5,3'-tri-iodothyronine (T3) in peripheral mammalian tissues. Subsequently it was shown that the antithyroid drug propylthiouracil (PTU) also blocked the metabolic effects of administered T4 in proportion to its inhibition of T4 to T3 conversion, indicati...
conclusions serum t4 and tsh levels in depressive patients were found to be significantly higher than those of the control group, indicating the association between serum t4 and tsh levels and depression in the subjects in 2010 - 2011 in hamedan, northwestern iran. objectives in this study, the serum levels of t3, t4, and tsh in patients with major depressive disorder have been compared to the ...
To investigate mechanisms of extrathyroidal thyroid hormone metabolism, conversion of thyroxine (T(4)) to 3,5,3'-triiodothyronine (T(3)) and degradation of 3,3',5'-triiodothyronine (rT(3)) were studied in rat liver homogenates. Both reactions were enzymatic. For conversion of T(4) to T(3), the K(m) of T(4) was 7.7 muM, and the V(max) was 0.13 pmol T(3)/min per mg protein. For rT(3) degradation,...
