 Context examples 

In vivo, triiodothyronine enters the nucleus and binds to nuclear thyroid hormone receptors that subsequently bind to thyroid response elements (TREs) located in target genes.

(Liothyronine, NCI Thesaurus)

The determination of the amount of free triiodothyronine present in a sample.

(Free Triiodothyronine Measurement, NCI Thesaurus)

In peripheral tissues, levothyroxine is deiodinated by 5'-deiodinase to form triiodothyronine (T3).

(Levothyroxine Sodium, NCI Thesaurus)

A measurement of the free triiodothyronine in a biological specimen.

(Free Triiodothyronine Measurement, NCI Thesaurus/CDISC)

The sodium salt form of liothyronine, a synthetic form of the levorotatory isomer of the naturally occurring thyroid hormone triiodothyronine (T3).

(Liothyronine sodium, NCI Thesaurus)

Thyroxine is de-iodinated to form triiodothyronine (T3) in the peripheral tissues.

(Levothyroxine, NCI Thesaurus)

Receptor binding by triiodothyronine in combination with recruited coactivators results in maximal transcriptional activation after binding to TREs; in general, binding of thyroid hormone receptor alone to TREs leads to repression of gene transcription
