Triiodothyronine Treatment: Effects on vastus lateralis skeletal muscle


ABSTRACT: Healthy men received 75 5g/d of T3 for 14 days. Microbiopsies of vastus lateralis skeletal muscle were performed before and after the treatment. For microarray experiments, we used samples from five subjects. After amplification of total RNA (Wang et al. 2000a), fluorescently labeled cDNA was prepared from each experimental sample. For each subject, probes from basal and T3 treatment conditions labeled with cyanine (Cy) 3 or Cy5 dyes were hybridized to cDNA microarray. After a filtering procedure to eliminate bad-quality spots and background correction, log2 transformed data for each experiment were normalized and centered to the mean. Set of arrays organized by shared biological context, such as organism, tumors types, processes, etc. Using regression correlation

Thyroid hormones are key regulators of metabolism that modulate transcription via nuclear receptors. Hyperthyroidism is associated with increased metabolic rate, protein breakdown, and weight loss. Although the molecular actions of thyroid hormones have been studied thoroughly, their pleiotropic effects are mediated by complex changes in expression of an unknown number of target genes. Here, we measured patterns of skeletal muscle gene expression in five healthy men treated for 14 days with 75 m  ...[more]
