To explore the hypothesis that alteration of T3 receptor expression may be an important mechanism controlling the tissue effects of thyroid hormones in the "sick euthyroid" syndrome, specific triiodothyronine (T3) receptor mRNAs were measured in tissues from normal subjects and from patients with liver disease, chronic renal failure, or with multiple organ failure on an intensive care unit (ICU). In all patient groups circulating free thyroxine and free T3 were reduced, while thyroid stimulating hormone remained normal. In patients with liver or renal disease, there were significant increases in levels of both alpha and beta T3 receptor mRNAs in peripheral mononuclear cells (PMNCs); in ICU patients there was a significant increase in beta mRNA. In patients with liver disease increases in T3 receptor mRNAs were not confined to PMNCs but were also found in liver biopsy specimens when levels were compared with those in normal donor liver. After liver transplantation, receptor mRNAs in PMNCs were similar to those in controls; likewise beta mRNA was similar in liver tissue to normal liver. There was, however, persistent elevation in alpha receptor mRNA. Increases in T3 receptor expression in non-thyroidal illness may be responsible for the maintenance of euthyroidism in the face of reduced levels of circulating thyroid hormones.

UI	MeSH Term	Description	Entries
D007676	Kidney Failure, Chronic	The end-stage of CHRONIC RENAL INSUFFICIENCY. It is characterized by the severe irreversible kidney damage (as measured by the level of PROTEINURIA) and the reduction in GLOMERULAR FILTRATION RATE to less than 15 ml per min (Kidney Foundation: Kidney Disease Outcome Quality Initiative, 2002). These patients generally require HEMODIALYSIS or KIDNEY TRANSPLANTATION.

D009693	Nucleic Acid Hybridization	Widely used technique which exploits the ability of complementary sequences in single-stranded DNAs or RNAs to pair with each other to form a double helix. Hybridization can take place between two complimentary DNA sequences, between a single-stranded DNA and a complementary RNA, or between two RNA sequences. The technique is used to detect and isolate specific sequences, measure homology, or define other characteristics of one or both strands.

D011518	Proto-Oncogene Proteins	Products of proto-oncogenes. Normally they do not have oncogenic or transforming properties, but are involved in the regulation or differentiation of cell growth. They often have protein kinase activity.

D011988	Receptors, Thyroid Hormone	Specific high affinity binding proteins for THYROID HORMONES in target cells. They are usually found in the nucleus and regulate DNA transcription. These receptors are activated by hormones that leads to transcription, cell differentiation, and growth suppression. Thyroid hormone receptors are encoded by two genes (GENES, ERBA): erbA-alpha and erbA-beta for alpha and beta thyroid hormone receptors, respectively.
