Abstract:
:Thyroid hormone (T3) and estradiol (Est) modulate biological processes by binding to nuclear receptor proteins that, through interactions with specific response elements in the regulatory regions of genes, modulate gene transcription. Est stimulation of estrogen receptor (ER)-positive breast carcinoma cell growth occurs through its ability to bind to the ER and activate gene transcription. We now report that physiological concentrations of T3 significantly enhance Est stimulation of growth of a number of human breast carcinoma cell lines. The effect of T3 is specific for Est stimulation of growth and has no effect on insulin-like growth factor-I stimulation of growth. The effect of T3 on enhancing Est-mediated growth was specifically blocked by the addition of ligands inducing retinoid X receptor (RXR) homodimer receptor formation, suggesting that RXR-thyroid nuclear receptor (TR) heterodimer formation is required for the T3-mediated effect on estradiol-stimulated growth. Four thyroid nuclear receptors have been described in tissues, TR alpha 1, alpha 2, beta 1, and beta 2. Breast carcinoma cells were found to express TR beta 1 and TR alpha 2 mRNA and very low levels of TR alpha 1 mRNA. T3 did not increase ER mRNA or protein levels and did not enhance Est-mediated increases in gene transcription of a number of genes, i.e., transforming growth factor-alpha and pS2 which contain estrogen-response elements (EREs) in their regulatory regions. However, T3 enhanced Est-stimulated ERE-TK-CAT activity. Thus significant cross-talk appears to occur between the TRs and ER and T3 appears to enhance Est-mediated gene transcription.
