Iodothyronines
WebIodothyronines produced by the thyroid are highly hydrophobic, and need to be bound to specific proteins for transport through the general blood circulation to their target tissues. In blood, thyroid hormones are not covalently bound to specific thyroid hormone … Web1 mei 2002 · The abilities of various iodothyronines and iodotyrosines to displace the binding of rT 3 to its specific antibody were tested in four to five different concentrations. Cross-reaction of the rT 3 antibody was minimal with all compounds tested. The highest relative cross-reactivity was found for 3,3′-T 2 (1.0%). l-T 3 and d-T 3 showed values of …

Weiss, in Encyclopedia of Endocrine Diseases (Second Edition), 2024. Other Iodothyronines. Progressive deiodination of T 4 and T 3 by the three known deiodinases gives rise to a number of different triiodothyronines and diiodothyronines.Of these, reverse T 3 (3,3′,5′-triiodothyronine) and 3,5-T 2 (3,5-diiodothyronine) have also …

Web12 jan. 2016 · As an effect of ATGL recruitment, iodothyronines stimulated the lipid mobilization from LDs then followed by the up-regulation of carnitine-palmitoyl-transferase (CPT1) expression and the stimulation of cytochrome-c oxidase (COX) activity that seems to indicate a stimulation of mitochondrial function.
WebTransport of iodothyronines by LAT1, LAT2, LAT3, and LAT4 will change their intracellular levels and consequently their metabolism by deiodinating enzymes. To study this, we cotransfected cells with LAT1–4, or MCT8 as a positive control, together with D1 or D3 and analyzed metabolism of T 4, T 3, rT 3, and 3,3′-T 2.
