Transcription profiling of hearts from wild type and thyroid hormone receptor beta-mutant mice (d337T TRb) treated with or without PPARalpha activator to study the molecular effect of thyroid hormone receptor on PPARalpha activation.

ABSTRACT: In this study we used the d337T TRb transgenic mouse that has been created to reproduce the human genetic disease known as resistance to thyroid hormone (RTH) as a model to determine if the d337T TRb mutation would have an effect on PPARa activation. A single amino acid deletion (d337T) abrogates thyroid hormone (T3) binding and transforms the thyroid hormone receptor (TRb) into a constitutive repressor. The principle goal was to determine if T3 regulates myocardial energy metabolism through its nuclear receptors. We introduced a known PPARa activator (WY14, 643) into control and d337T TRb transgenic mice then examined cardiac gene expression using Affymetrix 430_2 expression arrays and RT-PCR. We compared the gene expression of PPARa, RXRb and TRa,b and three PPARa target genes amo
