Nuclear hormone receptors exert transcriptional activation of target genes upon hormone induction via interactions with the basal transcription machinery. This interaction is mediated by cofactors which physically bind to receptors, thereby acting as coactivators or corepressors leading to activation or repression, respectively. Here we report the screening for and cloning of a peroxisome proli...
Gel shift assays have been employed to examine the association of the thyroid hormone receptor with specific DNA sequences in the 5'-flanking DNA of the rat growth hormone (rGH) gene. This DNA is known to have structure(s) that mediate thyroid hormone effects on the rGH promoter. The receptors used were obtained from preparations purified 300-500-fold from rat liver nuclear extracts and contain...
Peroxisome proliferator-activated receptors (PPARs) are members of the ligand-activated nuclear hormone receptor superfamily of transcription factors that includes receptors for steroids, thyroid hormone, retinoic acid, and vitamin D. Upon activation in the cytoplasm, PPARs heterodimerize with retinoid X receptors (RXR) and form a complex that translocates to the nucleus and regulates gene expr...
