Metabolism of triiodothyronine in rat hepatocytes.


The metabolism of T3 by isolated rat hepatocytes was analyzed by Sephadex LH-20 chromatography, HPLC, and RIA for T3 sulfate (T3S) and 3,3'-diiodothyronine (3,3'-T2). Type I iodothyronine deiodinase activity was inhibited with propylthiouracil (PTU), and phenol sulfotransferase activity by SO4(2-) depletion or with competitive substrates or inhibitors… (More)
