    Triiodothyronine, also known as T 3, is a thyroid affects almost every physiological process in the body, including growth and development, metabolism, body temperature, and heart rate.. Production of T 3 and its prohormone thyroxine (T 4) is activated by thyroid-stimulating hormone (TSH), which is released from the anterior pituitary gland. This pathway is part of a closed-loop. The maximum concentrations of plasma l ‐3,5,3′‐triiodothyronine and l ‐thyroxine are and ngmL −1 in arctic charr Salvelinus alpinus [], 4 and 11 ngmL −1 in coho salmon Oncorhynchus kisutch [], 4 and 14 ngmL −1 in Atlantic salmon Salmo salar [], and and ngmL −1 in masu salmon .

    Application 3,3′,5-Triiodo-L-thyronin e can be used for Insulin-like growth factor I assays performed by using a double antibody radioimmunoassay. The product can also be used for in vitro transfection of T cells.. Packaging 1, 5 g in poly bottle , , mg in poly bottle.   Triiodothyronine (T3) has been shown to induce cellular proliferation in the olfactory epithelium of parr, which corresponds to the changes seen in fish undergoing natural smoltification (Lema & Nevitt, ), and it has also been shown that T4 administration to chum salmon juveniles stimulates the N‐methyl‐D‐aspartate receptor subunit.

    In addition, we quantified heptic mRNA levels for the orphan nuclear receptors estrogen-related receptor α (esrra) and estrogen-related receptor γ (esrrg), which regulate mitochondrial gene expression and biogenesis, and gluconeogenesis, respectively (Villena et al., ; Kim et al., ).

Yearling coho salmon (Oncorhynchus kisutch) were fed diets containing triiodothyronine (T3; 4 or 12gmg), propylthiouracil (PTU; or mg/g), or both T3 (12μg/g) and PTU ( mg/g) from January 10 to May Plasma T4 and T3, concentrations were maintained within normal physiological limits in all groups of treated fish.

Abstract. It has been shown previously that the maximum binding capacity (MBC) of the putative 3,5,3′-triiodothyronine (T 3) receptor in red blood cells (RBCs) and tail tissue of Rana catesbeiana tadpoles is increased during development (1,2), and can be stimulated in RBCs by treatment with thyroid hormone (TH) (3).

The present study was performed to determine if the MBC of tadpole liver. The nuclear uptake of T 3 does not require the mediation of a cytoplasmic carrier as has been postulated for steroid hormones.

Cytosol proteins binding T 3 exhibit a substantially higher capacity and lower affinity than do nuclear sites. These proteins also bind thyroid hormone analogues with a different rank order than do nuclear sites (Dillmann et al., ).

A broad expression pattern of the thyroid hormone receptor (TR) genes, TRa and TRb, in brain, gill, liver, muscle, kidney, ovary, skin and eyeball of coho salmon (Harada et al., ), suggests. The specificity of the nuclear receptor, as judged by the relative affinities of thyroid hormone analogs, is in general agreement with data previously reported for lung and other organs.

A significant decrease in the maximum binding capacity of the lung T3 receptor occurs between 30 and 40 days of age: 0 to 30 days, +/- pmole T3/mg. The effect of tri-iodothyronine injection on the nuclear tri-iodothyronine receptor (putative thyroid-hormone receptor) was examined in rat liver.

Nuclear receptors were extracted from isolated nuclei with M-KCl, and their association constants (Ka) and maximal binding capacities (Cmax.) were determined by Scatchard analyses with and.

Abstract. The concept that thyroxine (T 4) or triiodothyronine (T 3) might act by modification of nuclear RNA synthesis was advanced by Tata in the early ’s (Tata, Ernster, and Suranyi, ).He reported that T 4 induced new RNA and protein synthesis, and indicated later that the earliest observable effect was on the function of nuclear magnesium-dependent polymerase involved in.
